+# Owner can never be changed due to self-assignment bugin auctionFactoryDebita and orderFactory
+
+### Summary
+
+Both buyOrderFactory.sol and auctionFactoryDebita.sol contracts contain an identical critical bug where the owner address is being assigned to itself (`owner = owner`) instead of being updated to the new address. This makes the ownership transfer functionality completely broken in both contracts, as the owner will always remain unchanged regardless of the input.
+
+
+### Root Cause
+
+In both contracts, the assignment statement `owner = owner` is a self-assignment that has no effect - it's simply assigning the state variable to itself rather than updating it with the new owner address parameter.
+
+**buyOrderFactory.sol:**
+```solidity
+function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner; // BUG: Self-assignment, owner never changes
+}
+```
+
+**auctionFactoryDebita.sol (same issue):**
+```solidity
+function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner; // BUG: Same self-assignment bug
+}
+```
+
+
+### Internal pre-conditions
+
+owner
+
+### External pre-conditions
+
+none
+
+### Attack Path
+
+1. Current owner calls `changeOwner(address newOwner)` with a new address
+2. Ownership checks pass
+3. `owner = owner` executes, but merely assigns the current owner address to itself
+4. Contract owner remains unchanged, making ownership transfer impossible
+
+### Impact
+
+Both contracts suffer from permanently locked ownership, which:
+
+- Makes owner addresses permanent after deployment
+- Prevents recovery if owner keys are compromised
+- Blocks transfer to new management structures
+- Makes it impossible to correct incorrectly set owner addresses
+- Could lead to permanently locked contract functionality if owner access is required for critical functions
+
+### PoC
+
+Paset this code in `BuyOrder.t.sol`
+
+```solidity
+ function testChangeOwnerShadowing() public {
+ address newOwner = address(0x03);
+
+ // Attempt to change owner on behalf of anyone
+ vm.startPrank(newOwner);
+ factory.changeOwner(newOwner);
+ vm.stopPrank();
+
+ // Log the owner after the failed attempt
+ console.log("Owner after failed change attempt:", factory.owner());
+ }
+```
+
+### Mitigation
+
+```solidity
+function changeOwner(address _newOwner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = _newOwner; // Actually update the owner
+}

+# `updateFunds()` function in `DebitaIncentives` contract skips potentially valid token pairs
+
+### Summary
+
+When `updateFunds()` is called at the end of the `matchOffersV3()` function execution it should update the funds of the user and the amount of the principle for any `principle/collateral` token pair that is whitelisted. However, as seen below when the loop finds a pair that is not whitelisted it returns instead of continuing to iterate through `informationOffers` array, ignoring potentially valid pairs.
+
+### Root Cause
+
+`DebitaIncentives:updateFunds()` function returns instead of continuing to iterate through subsequent token pairs.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L316-L318
+
+### Internal pre-conditions
+
+- more than one principle token is borrowed
+- that principle token and borrower's collateral token are not a whitelisted pair in `DebitaIncentives`
+- this pair is not the last one in `informationOffers` array
+
+### External pre-conditions
+
+--
+
+### Attack Path
+
+--
+
+### Impact
+
+Incorrect implementation of the function causes unfair loss of incentives.
+
+The more principle tokens are *after* the unwhitelisted pair in `informationOffers` array the more incentives are lost.
+
+### PoC
+
+--
+
+### Mitigation
+
+Consider the following change :
+```diff

+# Incorrect array sizing in pagination methods leads to underflow and DOS
+
+### Summary
+
+Multiple contracts in the system (auctionFactoryDebita, buyOrderFactory, DebitaV3Aggregator, DebitaIncentives) contain pagination methods that incorrectly calculate array size as `length - offset` instead of `length`. This leads to arithmetic underflow when the offset is greater than the length, causing the transaction to revert. This effectively creates a Denial of Service (DOS) vulnerability in pagination functionality across the system.
+

+
+### Root Cause
+
+In multiple contracts, pagination methods create new arrays with size `length - offset` instead of `length`. When offset is greater than length, this causes an arithmetic underflow:
+```solidity
+// Problematic array initialization in auctionFactoryDebita:
+DutchAuction_veNFT.dutchAuction_INFO[] memory result =
+ new DutchAuction_veNFT.dutchAuction_INFO[](length - offset); // BUG: Underflow when offset > length
+
+// Similar issue in buyOrderFactory:
+BuyOrder.BuyInfo[] memory _activeBuyOrders =
+ new BuyOrder.BuyInfo[](limit - offset); // BUG: Same underflow risk
+```
+
+### Internal pre-conditions
+
+- offset parameter must be greater than length parameter
+- At least one active order must exist in the system
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+- System has some active orders (e.g., 4 active auction orders)
+- legitimate user calls getActiveAuctionOrders with offset > length (e.g., offset=2, limit=1)
+- Function calculates array size as 1-2 = -1
+- Transaction reverts due to arithmetic underflow
+- Pagination functionality becomes unusable for these parameters
+
+### Impact
+
+- Pagination functionality breaks when offset > length
+- Frontend applications relying on these methods may become unusable
+- API integrations may fail unexpectedly
+- System monitoring and data retrieval functions may be disrupted
+- This issue affects multiple core contracts, making it a systemic problem

+# Inability to Change Ownership Due to Variable Shadowing
+
+### Summary
+
+The ` DebitaV3Aggregator::changeOwner` function in does not correctly update the `owner` due to a shadowed variable issue. As a result, the owner cannot successfully change their address, and the contract's ownership remains immutable after deployment. If the owner's address gets compromised, the protocol team do not have a chance to take quick actions of changing ownership.
+
+### Root Cause
+
+In [DebitaV3Aggregator.sol](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682), the function parameter `owner` shadows the state variable `owner`, causing the check `require(msg.sender == owner, "Only owner")` to always revert. since the `owner` variable within the function only references the function argument and not the state variable.
+```solidity
+function changeOwner(address owner) public {
+ //@audit this will always revert when there is an intention to change ownership
+ @>>require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+}
+```

+
+### External pre-conditions

+N/A
+
+### Attack Path
+
+N/A
+
+### Impact
+
+The protocol will be unable to change ownership. In the event that the current owner’s address is compromised, it will be impossible to transfer ownership to a secure address, resulting in a permanent loss of control over the contract.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+To fix the issue, rename the function parameter to avoid shadowing the state variable.
+```solidity

+# A malicious user can delete all the lendOrders in factory by repeatedly calling cancelOffer() & addFunds()
+
+### Summary
+
+A malicious user can delete all the lendOrders in the factory by repeatedly calling `cancelOffer()` & `addFunds()`
+
+### Root Cause
+
+In [addFunds](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L162)(), owner can add funds even after lendOrder is already cancelled ie it doesn't check if lendOrder is active or not. Also, cancelOffer() can be called again & again as this also doesn't check if lendOrder is active or not.
+
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+To understand this issue, let's go step by step:
+
+1. Suppose there are 10 lendOrders created by factory ie index = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] & 3rd index is owned by user1
+2. User1 decided to cancel his lendOrder and called cancelOffer(), this will set the availableAmount = 0 & call deleteOrder() on the factory contract
+```solidity
+ function cancelOffer() public onlyOwner nonReentrant {
+ uint availableAmount = lendInformation.availableAmount;
+ lendInformation.perpetual = false;
+@> lendInformation.availableAmount = 0;
+ require(availableAmount > 0, "No funds to cancel");
+ isActive = false;
+
+ SafeERC20.safeTransfer(
+ IERC20(lendInformation.principle),
+ msg.sender,
+ availableAmount
+ );
+ IDLOFactory(factoryContract).emitDelete(address(this));
+@> IDLOFactory(factoryContract).deleteOrder(address(this));
+ // emit canceled event on factory
+ }
+```
+3. deleteOrder() will set index to 0 & will replace the last index(9th) with 3rd index & will decrease the activeOrdersCount ie remaining index = [0, 1, 2, 3, 4, 5, 6, 7, 8]
+```solidity
+ function deleteOrder(address _lendOrder) external onlyLendOrder {
+ uint index = LendOrderIndex[_lendOrder];
+ LendOrderIndex[_lendOrder] = 0;
+
+ // switch index of the last borrow order to the deleted borrow order
+ allActiveLendOrders[index] = allActiveLendOrders[activeOrdersCount - 1];
+ LendOrderIndex[allActiveLendOrders[activeOrdersCount - 1]] = index;
+
+ // take out last borrow order
+ allActiveLendOrders[activeOrdersCount - 1] = address(0);
+ activeOrdersCount--;
+ }
+```
+4. Now, user1 calls addFunds() to add funds, which will increase the lendInformation.availableAmount
+```solidity
+ function addFunds(uint amount) public nonReentrant {
+...
+@> lendInformation.availableAmount += amount;
+ IDLOFactory(factoryContract).emitUpdate(address(this));
+ }
+```
+5. Again, user1 will call cancelOffer() and require statement will pass because at step-4 we added funds to increase availableAmount. Then again deleteOrder() of factory will be called
+6. This time deleteOrder() will replace the 8th(last index) with 0th index and count will decrease. User1 can repeat this process again and again to remove all the lendOrder from the factory
+
+### Impact
+
+A malicious user can delete all the lendOrder from factory contact, which will result in unexpected behavior/result when a original lendOrder is deleted.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Don't allow owner to add funds when lendOrder is not active. Also, add this check in cancelOffer()
+```diff
+ function addFunds(uint amount) public nonReentrant {
++ require(isActive, "Offer is not active");
+ require(
+ msg.sender == lendInformation.owner ||
+ IAggregator(aggregatorContract).isSenderALoan(msg.sender),
+ "Only owner or loan"
+ );
+ SafeERC20.safeTransferFrom(
+ IERC20(lendInformation.principle),
+ msg.sender,
+ address(this),
+ amount
+ );
+ lendInformation.availableAmount += amount;
+ IDLOFactory(factoryContract).emitUpdate(address(this));
+ }
+```

+# Ineffective Owner Update Logic in `changeOwner` Function
+
+## Summary
+
+The `changeOwner` function in the `AuctionFactory` contract fails to update the owner due to a logical error (`owner = owner;`), rendering it impossible to change the contract owner after deployment, even within the intended 6-hour window.
+
+## Vulnerability Details
+
+In `AuctionFactory` contract, there is a state variable `owner`
+```js
+address owner; // owner of the contract
+```
+Owner is set as msg.sender(contract deployer) in the constructor.
+```js
+ constructor() {
+ owner = msg.sender;
+ feeAddress = msg.sender;
+ deployedTime = block.timestamp;
+ }
+```
+There is a [changeOwner](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L218-L222) function which allows changing the current owner to a new owner within 6 hours of the contract deployment.
+```js
+ function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner; //@audit
+ }
+```
+The statement `owner = owner;` is ineffective as it assigns the argument owner back to itself.
+
+## Impact
+
+Faulty `changeOwner` function. Owner of the contract cant be change after deployment
+
+## Tools Used
+
+Manual Review
+
+## Recommendation
+
+Change the argument to `newOwner` and assign it to the `owner` state variable

+The problem is that input parameter `owner` is exactly the same with the storage variable `owner`. This will cause that only the input parameter `owner` takes effect in this function's scope. We cannot change owner.

+# Insufficient validation of the sequencerUptimeFeed in `DebitaChainlink::getThePrice()`
+
+## Summary
+Insufficient validation of the sequencerUptimeFeed in ``DebitaChainlink::getThePrice``
+## Vulnerability Details
+This is how ``sequencerUptimeFeed`` is validated:
+```javascript
+ function checkSequencer() public view returns (bool) {
+ (, int256 answer, uint256 startedAt, , ) = sequencerUptimeFeed
+ .latestRoundData();
+
+ // Answer == 0: Sequencer is up
+ // Answer == 1: Sequencer is down
+ bool isSequencerUp = answer == 0;
+ if (!isSequencerUp) {
+ revert SequencerDown();
+ }
+ console.logUint(startedAt);
+ // Make sure the grace period has passed after the
+ // sequencer is back up.
+ uint256 timeSinceUp = block.timestamp - startedAt;
+ if (timeSinceUp <= GRACE_PERIOD_TIME) {
+ revert GracePeriodNotOver();
+ }
+
+ return true;
+ }
+```
+However, it is not correctly validated. The `startedAt`can be 0 during an invalid round but that is not validated in the code above.
+Check the [Chainink Docs](https://docs.chain.link/data-feeds/l2-sequencer-feeds) and see for yourself. This is what you can see there:
+> `startedAt`: This timestamp indicates when the sequencer changed status. This timestamp returns `0` if a round is invalid. When the sequencer comes back up after an outage, wait for the `GRACE_PERIOD_TIME` to pass before accepting answers from the data feed. Subtract `startedAt` from `block.timestamp` and revert the request if the result is less than the `GRACE_PERIOD_TIME`.
+
+This makes the check below insufficient as `timeSinceUp` will equal `block.timestamp`since `startedAt` will be 0 making the check always pass.
+```javascript
+ uint256 timeSinceUp = block.timestamp - startedAt;
+ if (timeSinceUp <= GRACE_PERIOD_TIME) {
+ revert GracePeriodNotOver();
+ }

+Consider changing the name of the input parameter of the `DebitaV3Aggregator::changeOwner` function in such a way that it does not conflict with any state variables. For instance, we could use `address _owner` instead of `address owner` as shown below:
+
+```diff
+- function changeOwner(address owner) public {
++ function changeOwner(address _owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+- owner = owner;
++ owner = _owner;
+ }

+# The protocol assumes that every ERC20 has .decimals() function.
+
+### Summary
+
+Debita Finance uses `.decimals()` that ensures the calculation properly considers the token's precision. Without this, the computations might misrepresent the actual token values. However there are ERC20 that lacks this function and they are 100% ERC20 compatible.
+
+### Root Cause
+
+In [`DebitaV3Aggregator`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L167) There are three places where `.decimals()` is used:
+
+
+[DebitaV3Aggregator::L348](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L348):
+
+```solidity
+uint principleDecimals = ERC20(principles[i]).decimals();
+```
+
+[DebitaV3Aggregator::L371](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L371):
+
+```solidity
+uint decimalsCollateral = ERC20(borrowInfo.valuableAsset).decimals();
+```
+
+[DebitaV3Aggreagor::L453](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L455-L456):
+
+```solidity

+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+The Borrow offers or Lend offers that uses ERC20 without `.decimals()` function will not be able to be matched by anyone since the aggregator contracts expects both of them to implement it.
+
+
+The protocol's answer for the question about weird tokens from sherlock sayst that:
+
+> any ERC20 that follows exactly the standard (eg. 18/6 decimals)
+
+However, *exactly the standard* does not means that `decimals()` is included. According to the [Official EIP20 Documentation](https://eips.ethereum.org/EIPS/eip-20#decimals) this function is `OPTIONAL`
+
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Recommend using a tryCatch block to query the decimals. If it fails, hardcode it to 18 for scaling.

+# An attacker can wipe the orderbook in DebitaLendOfferFactory.sol
+
+### Summary
+
+A malicious actor can wipe the complete lend offer factory orderbook. Excluding gas costs, the attack does not bear any cost to the attacker. As a result, the "orderbook" implemented in DLOFactory will be emptied, resulting in a DOS-like state where lender funds and order matching will be temporarily inaccessible.
+
+### Root Cause
+
+The function `cancelOffer` only checks the existence of funds in the contract:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L148
+However, it does not check whether the offer has been canceled already (i.e. `require(isActive, "Offer is not active");`
+Similarly, it is also possible to add funds to an already canceled offer as the same check is missing here:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L162
+Therefore an attacker can repeatedly call `addFunds(uint amount)` and `cancelOffer()` on a single lend order to wipe the orderbook:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207
+
+### Internal pre-conditions
+
+N/A
+
+### External pre-conditions
+
+N/A
+
+### Attack Path
+
+1. Attacker creates lend order
+2. Attacker calls lendOrder.cancelOffer()
+3. Attacker repeatedly calls lendOrder.addFunds(uint amount) and lendOrder.cancelOffer() until orderbook is "empty" (activeOrdersCount == 0)
+
+### Impact
+
+The attacker can temporarily block order matching and withdrawals from lend orders (withdrawals will fail when the order book is empty due to integer underflow). Order matching can be fixed by resubmitting lend orders. Withdrawals can be fixed by submitting "dummy" lend orders with a trivial amount of tokens as start amount (e.g. 1) so that the real lend orders can be cancelled instead.

+It may be possible that the check is not performed so that lend orders can receive funds even when they were inactived. In that case, implementing a separate function to withdraw funds but not trigger deletion may also be a viable fix.

+# User's reward can be locked in DebitaIncentives
+
+### Summary
+
+Certain ERC20 tokens, such as [ZRX](https://etherscan.io/address/0xE41d2489571d322189246DaFA5ebDe1F4699F498#code) follows standard erc20 principle but do not revert on failed transfers but instead return false. This behavior can be exploited to manipulate and inflate the incentive calculations in `DebitaIncentives`. Specifically, malicious users can artificially increase the values of `lentIncentivesPerTokenPerEpoch` and `borrowedIncentivesPerTokenPerEpoch` in lines [269-273](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L269-L273), leading to locked rewards for legitimate users.
+
+### Root Cause
+
+The `IERC20::transferFrom` function in `DebitaIncentives` assumes that all transfers will revert on failure, rather than checking the return value to confirm success. This results in incorrect updates to incentive variables when interacting with tokens that do not conform to this assumption
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. A malicious user calls `DebitaIncentives::incentivizePair()` with a non-standard ERC20 token such as ZRX as incentiveToken, which does not revert on failed transfer
+
+2. The incentivizePair() function updates incentive variables:
+ * `lentIncentivesPerTokenPerEpoch[principle][hashVariables(incentivizeToken, epoch)]`
+ * `borrowedIncentivesPerTokenPerEpoch[principle][hashVariables(incentivizeToken, epoch)]`
+ These updates occur even if the malicious user does not have sufficient balance, as the transfer does not revert and no check for a `false` return value exists.
+
+3. The attacker can repeatedly call `incentivizePair()` to inflate these incentive values to arbitrary levels.
+
+4. When legitimate lenders and borrowers who used these weird tokens, attempt to claim rewards using `claimIncentives()`, the `amountToClaim` calculation in line [200-201](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L200-L201) is based on the inflated values. If the contract lacks sufficient token balance to pay out these rewards, no tokens are transferred.
+
+5. Despite the failed token transfer, the claim is marked as complete in `claimedIncentives[msg.sender][hashVariablesT(principle, epoch, token)]`. As a result, users are unable to claim their rewards in the future, effectively locking their incentives.
+
+### Impact
+
+1. Incentive variables (`lentIncentivesPerTokenPerEpoch` and `borrowedIncentivesPerTokenPerEpoch`) are artificially inflated, disrupting the reward system
+2. Rewards for lenders and borrowers who interacted with the protocol using some weird tokens (eg- ZRX) are permanently locked. Affected users will have no way to recover their rewards
+

+# wrong Update of bribeCountPerPrincipleOnEpoch in incentivizePair function in the DebitaIncentives Contract
+
+### Summary
+
+The bribeCountPerPrincipleOnEpoch mapping is incorrectly updated within the incentivizePair function in the DebitaIncentives Contract. Specifically, the logic increments the count for incentivizeToken instead of the intended principle. This leads to inconsistent data storage, where the bribe count for the principle remains unchanged, potentially resulting in incorrect indexing and logic failures in the contract.
+
+### Root Cause
+
+The statement bribeCountPerPrincipleOnEpoch[epoch][incentivizeToken]++; updates the count for incentivizeToken instead of principle.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L264
+
+The intention is incrementing the count for the principle (the primary identifier),
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L117-L120

+# Unauthorized Caller Will Bypass Ownership Update Affecting Contract Control
+
+### Summary
+
+The `changeOwner` function in the smart contract contains a critical flaw that allows any user to call the function without effectively changing the ownership of the contract. This issue arises from a naming conflict between the function parameter and the public variable `owner`, leading to a situation where the intended owner is not updated. This audit identifies the problem and offers recommendations for remediation.
+
+
+### Root Cause
+
+In [DebitaV3Aggregator](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682), the function parameter `owner` shadows the public state variable `owner`. As a result, when checking `msg.sender == owner`, it compares `msg.sender` against the parameter instead of the actual state variable, allowing unauthorized callers to bypass ownership updates.
+
+
+### Internal pre-conditions
+
+1. The contract must have an initialized public variable owner that represents the current owner of the contract.
+2. The deployedTime variable must be defined and set at the time of contract deployment.
+
+### External pre-conditions
+
+1. The caller of the function must be an address that is intended to be the new owner.
+2. The transaction must occur within 6 hours of contract deployment.
+
+### Attack Path
+
+1. Any user can call `changeOwner` with any address as a parameter.
+2. If they are also recognized as `msg.sender`, they will pass the check (`msg.sender == owner`), but since the parameter shadows the state variable, no actual change in ownership occurs.
+3. This allows unauthorized users to manipulate contract behavior without updating ownership.
+
+### Impact
+
+The flaw permits unauthorized users to invoke the function without affecting ownership, undermining contract security and control. This can lead to potential exploitation where malicious actors can gain access to sensitive functionalities that should only be available to the legitimate owner.
+
+
+### PoC
+
+To illustrate this vulnerability, consider the following scenario:
+1. Assume `owner` is set to `0x123...abc during deployment.
+2. An attacker (e.g., `0x456...def`) calls:
+
+```solidity
+changeOwner(0x456...def);
+```
+
+3. If `0x456...def` is also recognized as `msg.sender`, they will pass the check, but since `owner` in context refers to the parameter, no actual change occurs.
+
+This means that any user can call this function without changing ownership effectively, leading to potential exploitation.
+
+### Mitigation
+
+To remediate this issue, it is recommended to rename either the function parameter or the public variable so that they do not conflict. Here’s a corrected version of the function:
+```solidity
+function changeOwner(address newOwner) public {
+ require(msg.sender == owner, "Only owner can change ownership");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = newOwner; // Update state variable 'owner' correctly
+}
+```

+# Failure to Burn lenderID After Debt is Claimed in LendOffer Protocol
+
+### Summary
+
+In the payDebt function in the DebitaV3Loan contract, when the loan offer is a perpetual , and the owner of the lendOffer matches the currentOwnerOfOffer (i.e the current older of the lenderID),

+ both the principal and interest are correctly sent to the lendOffer contract, marking the debt as claimed. The protocol also updates offer.debtClaimed to true. However, it neglects to call the burn function on the ownershipContract to destroy the associated lenderID. This omission results in an orphaned lenderID, leading to inconsistencies in ownership records and potential misuse.
+
+### Root Cause
+
+The ownershipContract.burn(offer.lenderID) function is not invoked when a debt is successfully claimed and offer.debtClaimed is set to true.
+This oversight leaves the lenderID in existence, which should no longer represent a valid loan after the debt is claimed.
+
+### Internal pre-conditions
+
+The payDebt() function is called, and the conditions lendInfo.perpetual and lendInfo.owner == currentOwnerOfOffer evaluate to true.

+# DoS Vulnerability Allows NFT Collateral Orders to Fail Due to Improper Validation
+
+### Summary
+
+When creating a borrow order with NFT collateral (_isNFT == true), the contract attempts to check the balance of the collateral using the IERC20.balanceOf function. However, NFTs (ERC-721) do not track balances in this way, causing the validation to fail. This results in a Denial of Service (DoS) for borrowers attempting to create orders with NFT collateral, effectively blocking the creation of such orders.
+
+### Root Cause
+
+
+
+The root cause of the issue is the improper handling of collateral type differentiation in the order creation logic. Specifically:
+
+- The function assumes a uniform validation method (`IERC20.balanceOf`) for both ERC-20 and ERC-721 tokens.
+- NFTs (ERC-721) do not use a `balanceOf` function to track ownership, resulting in incorrect validation when `_isNFT == true`.
+- This mismatch leads to a failure in the collateral validation step, preventing the creation of borrow orders with NFT collateral.
+
+### **Key Problematic Line**
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L143C2-L144C66
+
+```solidity
+uint balance = IERC20(_collateral).balanceOf(address(borrowOffer));
+require(balance >= _collateralAmount, "Invalid balance");
+```
+
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L89C9-L93C1
+
+```solidity
+if (_isNFT) {
+ require(_receiptID != 0, "Receipt ID cannot be 0");
+ require(_collateralAmount == 1, "Started Borrow Amount must be 1");
+ }
+```
+
+For NFT collateral, this check is invalid because:
+- `IERC20.balanceOf` does not apply to ERC-721 tokens.
+- NFTs are verified through ownership (`IERC721.ownerOf`), not balances.
+
+This oversight causes the logic to break for NFT-based borrow orders because the balance would be zero and collateralAmount 1.
+
+
+### Impact
+
+Borrowers attempting to create a borrow order with NFT collateral (`_isNFT == true`) will fail the collateral validation step due to the inappropriate use of `IERC20.balanceOf`.
+
+
+
+### Mitigation
+
+
+Update the collateral validation to differentiate between fungible (ERC-20) and non-fungible (ERC-721) tokens:
+
+```solidity
+if (_isNFT) {
+ require(
+ IERC721(_collateral).ownerOf(_receiptID) == address(borrowOffer),
+ "NFT not transferred"
+ );
+} else {
+ uint balance = IERC20(_collateral).balanceOf(address(borrowOffer));
+ require(balance >= _collateralAmount, "Invalid balance");
+}
+```

+# Entitled lenders/borrowers not able to claim incentives

+### Summary
+
+When a borrower order is matched with multiple lend offers and there is a middle order principle token that is not added as whitelisted pair in `DebitaIncentives`, then all the following principal token lenders will not be able to claim incentives.
+
+### Root Cause
+
+[Source](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L316C13-L318C14)

+```
+
+Because of this issue, incentives are not updated for the following whitelisted pairs in the loop.

+1. Borrower creates a borrow order, accepting AERO, DAI and BUSD as principles and offers NFR as collateral
+2. Lender1 creates lend order with AERO as principle
+3. Lender2 creates lend order with DAI as principle
+4. Lender3 creates lend order with BUSD as principle
+5. Owner of `DebitaIncentives` whitelists AERO/NFR and BUSD/NFR pairs (note that DAI is not whitelisted)
+6. Incentivizer incentivizes above two pairs
+7. Time lapses 15 days epoch is changed
+8. Connector matches the borrow order with above three lend offers in same sequence
+9. Time lapses 15 days epoch is changed
+10. Lender3 with the lend offer having BUSD as principle (that is whitelisted and incentivized), tries to claim incentives, but fails and transaction reverts.
+
+### Impact
+
+Entitled lenders/borrowers will not be able to claim the incentives because funds will not be updated in above mentioned scenario.

+# Last lenders to a defaulted loans which utilizes TaxTokensReceipt NFT as collateral, won't be able to withdraw their collateral.
+
+### Summary
+
+The ``TaxTokenReceipt.sol`` contract purpose is to allow people to deposit Fee on transfer tokens, and in exchange mints them an NFT that they can use to create borrow orders, with the specified FOT token representing the underlying asset. As we can see from the [TaxTokenReceipt::deposit()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L58-L75) function, and the comment above it:
+```solidity
+ // expect that owners of the token will excempt from tax this contract
+ function deposit(uint amount) public nonReentrant returns (uint) {
+ uint balanceBefore = ERC20(tokenAddress).balanceOf(address(this));
+ SafeERC20.safeTransferFrom(
+ ERC20(tokenAddress),
+ msg.sender,
+ address(this),
+ amount
+ );
+ uint balanceAfter = ERC20(tokenAddress).balanceOf(address(this));
+ uint difference = balanceAfter - balanceBefore;
+ require(difference >= amount, "TaxTokensReceipts: deposit failed");
+ tokenID++;
+ tokenAmountPerID[tokenID] = amount;
+ _mint(msg.sender, tokenID);
+ emit Deposited(msg.sender, amount);
+ return tokenID;
+ }
+```
+There will be some kind of whitelist which is expected to allow a certain FOT token not to charge any fee when deposited into the ``TaxTokensReceipt.sol`` contract. If the NFT is used as a collateral in a borrow order, and that borrower fails to repay his debt, then an auction for said NFT will be created. The ``sellingToken`` of the auction will be the underlying FOT token of the ``TaxTokensReceipt.sol`` contract. When somebody decides to buy the NFT on auction he has to call the [Auction::buyNFT()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109-L161) function:
+```solidity
+ function buyNFT() public onlyActiveAuction {
+ // get memory data
+ dutchAuction_INFO memory m_currentAuction = s_CurrentAuction;
+ // get current price of the auction
+ uint currentPrice = getCurrentPrice();
+ // desactivate auction from storage
+ s_CurrentAuction.isActive = false;
+ uint fee;
+ if (m_currentAuction.isLiquidation) {
+ fee = auctionFactory(factory).auctionFee();
+ } else {
+ fee = auctionFactory(factory).publicAuctionFee();
+ }
+
+ // calculate fee
+ uint feeAmount = (currentPrice * fee) / 10000;
+ // get fee address
+ address feeAddress = auctionFactory(factory).feeAddress();
+ // Transfer liquidation token from the buyer to the owner of the auction
+ SafeERC20.safeTransferFrom(
+ IERC20(m_currentAuction.sellingToken),
+ msg.sender,
+ s_ownerOfAuction,
+ currentPrice - feeAmount
+ );
+
+ SafeERC20.safeTransferFrom(
+ IERC20(m_currentAuction.sellingToken),
+ msg.sender,
+ feeAddress,
+ feeAmount
+ );
+
+ // If it's a liquidation, handle it properly
+ if (m_currentAuction.isLiquidation) {
+ debitaLoan(s_ownerOfAuction).handleAuctionSell(
+ currentPrice - feeAmount
+ );
+ }
+ IERC721 Token = IERC721(s_CurrentAuction.nftAddress);
+ Token.safeTransferFrom(
+ address(this),
+ msg.sender,
+ s_CurrentAuction.nftCollateralID
+ );
+
+ auctionFactory(factory)._deleteAuctionOrder(address(this));
+ auctionFactory(factory).emitAuctionDeleted(
+ address(this),
+ s_ownerOfAuction
+ );
+ // event offerBought
+ }
+```
+ There is a separate problem in the [Auction::buyNFT()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109-L161) function, where the function will always revert, because in the overridden [TaxTokensReceipt::transferFrom()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L93-L120) function neither the ``to`` nor the ``from`` addresses are whitelisted. However this is a separate issue, and fixing it doesn't prevent the issue described in this report. As can be seen from the above code snippet, some price calculations are performed, then the FOT token is transferred to the feeAddress and to the appropriate Loan contract. Then the [DebitaV3Loan::handleAuctionSell()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L318-L334) function is called:
+```solidity
+ function handleAuctionSell(uint amount) external nonReentrant {
+ require(
+ msg.sender == auctionData.auctionAddress,
+ "Not auction contract"
+ );
+ require(auctionData.alreadySold == false, "Already sold");
+ LoanData memory m_loan = loanData;
+ IveNFTEqualizer.receiptInstance memory nftData = IveNFTEqualizer(

+ ).getDataByReceipt(m_loan.NftID);
+ uint PRECISION = 10 ** nftData.decimals;
+ auctionData.soldAmount = amount;
+ auctionData.alreadySold = true;
+ auctionData.tokenPerCollateralUsed = ((amount * PRECISION) /
+ (loanData.valuableCollateralUsed));
+ Aggregator(AggregatorContract).emitLoanUpdated(address(this));
+ }
+```
+
+As can be seen from the code snippet above there are no checks that check what is the actual amount of tokens that was transferred to the contract. The transferred amount is assumed to be the currentPrice - feeAmount from the [Auction::buyNFT()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109-L161) function:
+```solidity
+ debitaLoan(s_ownerOfAuction).handleAuctionSell(
+ currentPrice - feeAmount
+ );
+```
+Let's consider the following scenario:
+ - The collateral used for the borrow order is a TaxTokensReceipt NFT which has **2e18** locked amount, the decimals are **18**.
+ - The requested principal is USDC, and the borrower has requested **2_700e6 USDC** for **1e18** of the underlying token in the TaxTokensReceipt NFT, this is a ratio of **2_700e6**.
+ - The borrow order is matched against 2 separate lend orders, each providing **2_700e6 USDC** as the principal token. And each infoOfOffers for the lenders has ``collateralUsed`` = **1e18**
+ - When the loan is created the ``valuableCollateralUsed`` parameter of the loan will be equal to **2e18**
+ - Consider the underlaying FOT token has **5%** fee on transfer
+ - The loan defaults, and the [createAuctionForCollateral()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L417-L489) function is called, which creates an auction for the NFT.
+ - Consider there is a buyer who buys the NFT immediately via the [Auction::buyNFT()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109-L161) function. Consider the Debita protocol doesn't charge fees for easier calculations.
+ - The user who calls the the [Auction::buyNFT()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109-L161) function will have to transfer 2e18 of the NFT underlying token, however there is 5% fee on transfer to addresses that are not the ``TaxTokensReceipt.sol`` contract, thus the actual amount that will be transferred to the ``DebitaV3Loan.sol`` instance will be **2e18 - (2e18 \* 5%) = 1.9e18**, but the ``amount`` parameter of the [DebitaV3Loan::handleAuctionSell()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L318-L334) function will be **2e18**
+ - Then the tokenPerCollateralUsed will calculated in the following way
+```solidity
+auctionData.tokenPerCollateralUsed = ((amount * PRECISION) / (loanData.valuableCollateralUsed));
+```
+ - We get **(2e18 \* 1e18) / 2e18 = 1e18**
+ - When the first lender call the [claimCollateralAsLender()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L340-L372) function, it will internally call the [claimCollateralAsNFTLender()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L374-L411) function, and the amount that is transferred to the lender will be calculated in the following way:
+```solidity
+uint payment = (auctionData.tokenPerCollateralUsed * offer.collateralUsed) / (10 ** decimalsCollateral);
+```
+ - payment will be equal to **(1e18 \* 1e18) / 1e18 = 1e18**
+ - The ``DebitaV3Loan.sol`` instance will transfer 1e18 of the underlying tokens to the first lender (the first lender will receive 0.95e18, considering that there is 5% fee on transfer)
+ - However when the second lender decides to claim his collateral, his payment will be calculated to be equal to **1e18** as well, however the ``DebitaV3Loan.sol`` instance only has **0.9e18** tokens. As only **1.9e18** underlying tokens were transferred to it from the auction. The call to the [claimCollateralAsLender()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L340-L372) function will revert as there are not enough funds in the contract.
+
+This results in second lender essentially loosing his claim to the underlying tokens which act as a collateral, and those underlying tokens will be locked in the contract forever. There are no partial withdraws or any sweeping functions. The last user to withdraw won't be able to, essentially loosing the initial principal he provided to the borrower. Depending on the amount of the loan, the way orders are matched, the price at which the underlying collateral is bough, and the fee charged on transfer by the underlying FOT token, it is possible that several of the last users that wish to claim their share of the collateral won't be able to.
+
+### Root Cause
+The [DebitaV3Loan::handleAuctionSell()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L318-L334) function expects that the amount parameter provided to it from the [Auction::buyNFT()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109-L161) function will be equal to the actual amount of tokens that is transferred to the ``DebitaV3Loan.sol`` instance, however that won't be the case when the collateral is a TaxTokensReceipt NFT, and the underlying asset is a FOT token.
+
+### Internal pre-conditions
+
+1. Borrower creates a Borrow Order utilizing a ``TaxTokenReceipt.sol`` NFT, with the underlying collateral being a FOT token.
+2. The Borrower defaults on his loan, and the loan is liquidated.
+3. The bug regarding the [Auction::buyNFT()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109-L161) function, reverting due to the NFT not being able to be transferred is fixed.

+The DebitaFinance team claims to support FOT tokens via the ``TaxTokensReceipt.sol`` contract, and that the underlying FOT token won't charge fees when it is being deposited/transferred only to the ``TaxTokensReceipt.sol`` contract. However when a TaxTokensReceipt NFT is used as a collateral by a borrower, and that borrower defaults on his loan, due to the nature of FOT tokens, the last lender won't be able to withdraw his share of the underlying token of the collateral.

+_No response_
+
+### Mitigation
+
+Consider whether you want to support FOT tokens, as the current implementation is not supporting all FOT tokens as deposits in the ``TaxTokensReceipt.sol`` contract can happen only for certain tokens that don't charge fees when depositing into certain contracts. Otherwise the whole flow has to be changed, the [DebitaV3Loan::handleAuctionSell()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L318-L334) function, has to be called lets say by the borrower, or by lenders so it can check the balance before and after the FOT tokens are transferred from the Auction, and use that amount to calculate the ``auctionData.tokenPerCollateralUsed``.

+# The DebitaFinance protocol claims to support FOT tokens, but it doesn't
+
+### Summary
+
+According to the Readme the DebiteFinance protocol supports FOT tokens via the ``TaxTokensReceipt.sol`` contract:
+> Fee-on-transfer tokens will be used only in TaxTokensReceipt contract
+
+However this is not the case, as we can see from the [deposit()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L58-L75) function:
+```solidity
+ // expect that owners of the token will excempt from tax this contract
+ function deposit(uint amount) public nonReentrant returns (uint) {
+ uint balanceBefore = ERC20(tokenAddress).balanceOf(address(this));
+ SafeERC20.safeTransferFrom(
+ ERC20(tokenAddress),
+ msg.sender,
+ address(this),
+ amount
+ );
+ uint balanceAfter = ERC20(tokenAddress).balanceOf(address(this));
+ uint difference = balanceAfter - balanceBefore;
+ require(difference >= amount, "TaxTokensReceipts: deposit failed");
+ tokenID++;
+ tokenAmountPerID[tokenID] = amount;
+ _mint(msg.sender, tokenID);
+ emit Deposited(msg.sender, amount);
+ return tokenID;
+ }
+```
+The FOT tokens are expected not the charge any fee when they are being deposited into the ``TaxTokensReceipt.sol`` contract, however most already created tokens that are being used don't have such mechanisms. This means that the majority of FOT tokens can't be utilized within the DebiteFinance protocol, contrary to what the protocol team claims.

+### Root Cause

+In `DebitaV3Aggregator::changeOwner` the `owner` parameter name shadows the name of `owner` storage variable.

+# `addFunds()` can be called on an inactive lend order leading to deleted lend offer still being usable for matching
+
+### Summary
+
+`cancelOffer()` functions in both `DBOImplementation` and `DLOImplementation` contracts are meant to permanently disactivate given borrow/lend orders. Although they successfully set `isActive` variable to `false`:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L195
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L149
+, they fail to update `isBorrowOrderLegit` and `isLendOrderLegit` mappings on the factory contracts.
+
+The lend order has an `addFunds()` function that allows the increase of `availableAmount`. Because this function and `acceptLendingOffer()` fail to revert when `isActive` is `false`, the canceled lend offer can be successfully used in `matchOffersV3()`.
+
+As the borrow order does not have such `addFunds()` functionality it can be used in `matchOffersV3()` and pass `isBorrowOrderLegit` check, but it'll fail when `acceptBorrowOffer()` is called because `availableAmount` is still set to 0 after cancelation. So the root cause's impact is limited to lend offers.
+
+### Root Cause
+
+- `isBorrowOrderLegit` and `isLendOrderLegit` mappings for deleted orders are not set to `false` in `deleteOrder()` and `deleteBorrowOrder()` functions leading to `matchOffersV3()` having insufficient order validation
+- `addFunds()`, `acceptLendingOffer()`, and `cancelOffer()` can be called when if `isActive` is `false` in `DLOImplementation` contract
+
+
+### Internal pre-conditions
+
+- lend offer is canceled and then included for offer matching, either by a random user or the owner of the lend order
+
+
+### External pre-conditions
+
+--
+
+### Attack Path
+
+--
+
+### Impact
+
+A canceled offer can still be used rendering the offer cancellation and order deletion mechanisms broken and useless.
+
+This is pure speculation but the off-chain mechanisms might encounter issues when inactive lend orders successfully emit new events - for instance, when `acceptLendingOffer()` executes.
+
+### PoC
+
+To visualize how this vulnerabilitiy works add the following test to `TwoLendersERC20Loan.t.sol` test file :
+```solidity
+ function test_canceledOfferUsedForMatching() public {
+ // cancel existing lend offer
+ LendOrder.cancelOffer();
+ DLOImplementation.LendInfo memory lendInformation = LendOrder.getLendInfo();
+ assertEq(lendInformation.perpetual, false);
+ assertEq(lendInformation.availableAmount, 0);
+ assertEq(LendOrder.isActive(), false);
+ // adding funds to a NON-ACTIVE lend offer
+ AEROContract.approve(address(LendOrder), 5e18);
+ LendOrder.addFunds(5e18);
+ lendInformation = LendOrder.getLendInfo();
+ assertEq(lendInformation.availableAmount, 5e18);
+
+
+ matchOffers();
+ }
+```
+and run
+```shell
+forge test --mt test_canceledOfferUsedForMatching -vvv
+```
+This test case cancels existing valid lend offer. Then adds back funds to it and successfully calls `matchOffers()` where a deleted order is used in a loan.
+
+### Mitigation
+
+The simplest way to solve this issue is to set `isBorrowOrderLegit` and `isLendOrderLegit` to false when deleting an order AND make sure to add the following check to `addFunds()`, `cancelOffer()` (for both lender and borrow offers ), `acceptLendingOffer()` and `acceptBorrowOffer()` functions:
+```solidity
+require(isActive, "Offer is not active");
+```
+Note that this check still allows `addFunds()` to be called when `availableAmount` is zero if `perpetual` is `true` because in that case `isActive` cannot be set to `false`.
+
+Although I don't see any serious impact other than `BorrowOrderUpdated()` event emission caused by lack of such validation in the `updateBorrowOrder()` function, consider adding it there as well - `updateLendOrder()` is already checking whether the offer is active.
+
+If `isBorrowOrderLegit` and `isLendOrderLegit` are meant to exclusively check whether given order was created in a factory, `matchOffersV3()` needs to check `isActive` status of the used offers.

+# Front-running prevents lenders from changing perpetual status of orders
+
+### Summary
+
+Whenever a lender calls [DLOImplementation::changePerpetual()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L178-L188) to change the perpetual status of their lend order from `false` to `true`, anyone can front-run this by calling `DebitaV3Aggregator::matchOffersV3()` to match the lend order with a borrow order.
+This prevents the perpetual status from being changed.
+
+### Root Cause
+
+In `DLOImplementation:131`, the lend order is marked as inactive if its perpetual status is currently set to `false` and the available amount is `0`. This causes calls to change the perpetual status of the lend order to revert.
+
+### Internal pre-conditions
+
+1. A borrow order compatible with the lend order must be available. If not, the user could create a compatible one in their front-running call.
+
+### External pre-conditions
+
+None.
+
+### Attack Path
+
+1. LenderA calls `DLOFactory::createLendOrder()` to create a non-perpetual LendOrderA.
+2. In the future, LenderA decides to use the perpetual feature of the protocol and calls `DLOImplementation::changePerpetual()` to set the perpetual status of the not fully filled LendOrderA to `true`.
+3. A malicious actor front-runs this call by matching LendOrderA with a compatible borrow order, fully filling LendOrderA. As a result, the perpetual status cannot be changed.
+
+### Impact
+
+Lenders will not be able to change the perpetual status of their lend order to `true` once it is set to `false`.
+This means the perpetual lend order feature will not be available for some orders. Lenders need to create perpetual lend orders from the beginning if they wish to use that feature. If their only available funds are tied up in a lend order whose perpetual status they wanted to change to `true`, they would need to wait for the borrower to repay the debt before creating a new perpetual lend order. This process could take months.
+
+### PoC
+
+Add the following test to `BasicDebitaAggregator.t.sol`:
+
+```solidity
+function testChangePerpetualRevert() public {
+ address[] memory lendOrders = allDynamicData.getDynamicAddressArray(1);
+ uint[] memory lendAmountPerOrder = allDynamicData.getDynamicUintArray(
+ 1
+ );
+ uint[] memory porcentageOfRatioPerLendOrder = allDynamicData
+ .getDynamicUintArray(1);
+ address[] memory principles = allDynamicData.getDynamicAddressArray(1);
+ uint[] memory indexForPrinciple_BorrowOrder = allDynamicData
+ .getDynamicUintArray(1);
+ uint[] memory indexForCollateral_LendOrder = allDynamicData
+ .getDynamicUintArray(1);
+ uint[] memory indexPrinciple_LendOrder = allDynamicData
+ .getDynamicUintArray(1);
+
+ lendOrders[0] = address(LendOrder);
+ lendAmountPerOrder[0] = 5e18;
+ porcentageOfRatioPerLendOrder[0] = 10000;
+ principles[0] = AERO;
+
+ address loan = DebitaV3AggregatorContract.matchOffersV3(
+ lendOrders,
+ lendAmountPerOrder,
+ porcentageOfRatioPerLendOrder,
+ address(BorrowOrder),
+ principles,
+ indexForPrinciple_BorrowOrder,
+ indexForCollateral_LendOrder,
+ indexPrinciple_LendOrder
+ );
+
+ vm.expectRevert("Offer is not active");
+ LendOrder.changePerpetual(true);
+}
+```
+
+### Mitigation
+
+A mitigation for this vulnerability cannot be easily implemented. It should be considered allowing lenders to change the perpetual status of their lend orders even when they are fully filled, as funds can still be added when the lend order is inactive.

+# DebitaChainlink doesn't validate minAnswer/maxAnswer
+
+### Summary
+
+According to the readme the protocol will be deployed to Optimism
+>On what chains are the smart contracts going to be deployed?
+Sonic (Prev. Fantom), Base, Arbitrum & OP
+
+The current implementation of the ``DebitaChainlink.sol`` contract doesn't validate the minAnswer/maxAnswer as can be seen from the [getThePrice()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L30-L47) function:
+
+```solidity
+ function getThePrice(address tokenAddress) public view returns (int) {
+ // falta hacer un chequeo para las l2
+ address _priceFeed = priceFeeds[tokenAddress];
+ require(!isPaused, "Contract is paused");
+ require(_priceFeed != address(0), "Price feed not set");
+ AggregatorV3Interface priceFeed = AggregatorV3Interface(_priceFeed);
+
+ // if sequencer is set, check if it's up
+ // if it's down, revert
+ if (address(sequencerUptimeFeed) != address(0)) {
+ checkSequencer();
+ }
+ (, int price, , , ) = priceFeed.latestRoundData();
+
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+ require(price > 0, "Invalid price");
+ return price;
+ }
+```
+It only checks whether the price is bigger than 0. However most of the data feeds on Optimism still return minAnswer/maxAnswer.
+
+For example:
+- The USDT/USD data feed [aggregator contract](https://optimistic.etherscan.io/address/0xAc37790fF4aBf9483fAe2D1f62fC61fE6b8E4789#readContract), we can still see that the returned minAnswer is **1000000**
+- The BTC/USD data feed [aggregator contract](https://optimistic.etherscan.io/address/0x0C1272d2aC652D10d03bb4dEB0D31F15ea3EAb2b#readContract), we can still see that the returned minAnswer is **10000000000**
+
+Most of the data feeds on OP function in this way, given that the protocol is expected to work with a lot of different tokens, this will be problematic.
+
+### Root Cause
+
+Missing minAnswer/maxAnswer check in the [getThePrice()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L30-L47) function.

+
+### Impact
+
+If a scenario similar to the LUNA crash happens again, for example the USDT/USD pair will be returning prices that are bigger than the actual price. If users utilize oracles and LTVs to get their desired ratio, and the actual USDT/USD price is less than the minAnswer returned from the data feed, borrowers will receive much less USDT tokens for the collateral they are providing, than they are supposed to.

+# Owner of managed veAERO will steal all the collateral to lenders
+
+### Summary
+
+The owner of a managed veAERO can create a loan using that veNFT as collateral and steal it at any point in time, leaving lenders without collateral when the loan defaults.
+
+### Root Cause
+
+The root cause is that the `veNFTAerodrome` contract allows depositing managed veAERO, which has a different behavior than normal veAERO.
+
+### Internal pre-conditions
+
+1. The owner of the managed veAERO NFT has to open a loan using that managed veAERO as collateral.
+
+### External pre-conditions
+
+1. The attacker must obtain managed veAERO. Currently, this can be done by requesting one directly to the Aerodrome protocol.
+
+These managed veAERO NFTs are called Relays on the Aerodrome front end. The website states the following about those:
+> Partner protocols can request a Relay strategy, this will soon require an open governance proposal to be voted and passed by the veAERO voters.
+
+Currently, there are more than 45 of these Relays so any of those can execute this attack and steal a great amount of funds from lenders within Debita. Also, an attacker could get one from Aerodrome and then execute this attack in Debita.
+
+### Attack Path
+
+1. The attacker gets one managed veAERO (Relay), or it already has one
+2. The attacker then creates a normal veAERO token with a ton of funds and deposits into that Relay (`Voter::depositManaged`), so the locked amount of AERO on the Relay is now really high.
+3. The attacker locks that Relay in [`veNFTAerodrome`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/veNFTS/Aerodrome/Receipt-veNFT.sol#L63-L111) and gets a `veNFTVault`, which uses as collateral for a loan.
+4. When the loan is open and the attacker has received the loaned funds, it uses the normal veAERO and withdraws the delegated amount to the Relay (`Voter::withdrawManaged`).
+5. Time passes and the loan defaults.
+6. When the lenders want to claim the collateral, the locked amount of AERO within the Relay will be 0, meaning the collateral left in the loan will be worthless.
+
+### Impact
+
+An attacker can open a big loan using a managed veAERO (Relay) as collateral and then steal all that collateral from the lenders. This is a direct and significant loss of funds for lenders, hence the high severity.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+To mitigate this issue, do not allow depositing managed veAERO (Relay) into `veNFTAerodrome` so they cannot be used as collateral.

+# When extending a loan `missingBorrowFee` will always be larger than it should be due to incorrect implementation
+
+### Summary
+
+Due to incorrect fee calculation in `extendLoan()` function the borrower that initially paid less than `maxFee` will pay `maxFee - PercentageOfFeePaid` for the extended loan duration *REGARDLESS* of whether the new loan duration should result in `maxFee` threshold being met.
+
+### Root Cause
+
+When `feeOfMaxDeadline` is calculated:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L602
+the resulting value will be extremely large because `offer.maxDeadline` is a value set to `lendInfo.maxDuration + block.timestamp` in `matchOffersV3()`:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L511
+And therefore the following condition will always be met:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L604-L605
+
+-
+
+### Internal pre-conditions
+
+- valid loan is created with initial duration of < 20 days
+- the borrower decides to extend the loan after 10% of the loan duration
+
+
+### External pre-conditions
+
+--
+
+### Attack Path
+
+--
+
+### Impact
+
+Borrowers will have to pay more fees than they should when extending a loan, leading to significant loss of funds ( > 0.01% and > 10$ ).
+
+Assume that the initial duration was 5 days and the borrower paid `0.2%` fee. After 1 day they decided to extend the loan. The max loan duration for the complementary lend order was 7 days ( lonely lend order for simplicity ). The borrower expects to pay an extra `0.08%` fee for the additional two days ( `feePerDay * 2` ). Instead, they pay `0.6%` ( `0.8% - 0.2%` ).
+
+Sherlock's medium severity issue criteria:
+A relevant loss is said to be a user's loss of more than 0.01% and 10 USD of principal. As illustrated above it's easy for this issue to cause a loss of `0.52%` of principal (0.6%-0.08%), for which to be more than 10 USD the loan has to be for ~1923 USD of value in the given principal (10/0.0072) - practical amount for a loan.
+
+### PoC
+
+It can be provided if required to prove medium severity. The `maxDeadline` is clearly not meant to be used for this calculation so the PoC for that seems unnecessary.
+
+### Mitigation
+
+Consider utilizing `extendedTime` variable ( which is currently unused ) to calculate the missing borrow fee that has to be paid directly:
+```diff
+- uint feeOfMaxDeadline = ((offer.maxDeadline * feePerDay) / 86400);
++ uint missingBorrowFee = ((extendTime * feePerDay) / 86400);
+```
+and then add `missingBorrowFee` to `PorcentageOfFeePaid` and ensure it's not larger than `maxFee` - if this sum would be smaller than `minFee` then `missingBorrowFee` should be 0 - the borrower already paid 0.2% in `matchOffersV3()`.

+# Borrower will grief lenders by extending the lock of veNFTs when loan defaults
+
+### Summary
+
+When a loan that is using a veNFT as collateral defaults, the borrower can grief the lenders by extending the lock the the maximum duration allowed.
+
+### Root Cause
+
+The root cause is that the borrower of a loan is allowed to extend the lock duration of a veNFT when the loan is defaulted, griefing the lenders.
+
+- [`veNFTAerodrome::extendMultiple`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/veNFTS/Aerodrome/Receipt-veNFT.sol#L155-L167)

+
+
+
+### Internal pre-conditions
+
+- There must be a loan using veAERO as collateral and the loan must default.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. A malicious borrower gets a veNFT that is locked for some amount of time (e.g. 2 months).
+2. The borrower locks that veNFT into a receipt to use it as collateral for a loan
+3. A loan is created with that veNFT as collateral.
+4. Time passes and the loan defaults.
+5. The borrower then calls `extendMultiple` to extend the loan duration of the veNFT with the maximum duration allowed (4 years for Aerodrome and 26 weeks for Equalizer).
+6. When the veNFT is auctioned, the final price for that veNFT will likely be lower because the lock amount is now higher.
+
+### Impact
+
+A borrower of a defaulted loan can extend the lock duration of the veNFT collateral, therefore griefing the lenders because they will receive less funds for the auction.
+
+It's complicated to theorize how much the value of a veNFT will decrease if it's locked for 4 years or for 2 months but it's safe to assume that will cause some loss of funds, even if constrained; hence the medium severity.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+To mitigate this issue, is recommended to take the following precautions before allowing a manager of a veNFT to increase the lock amount:
+- Don't allow to increase the lock duration if the loan is defaulted.
+- Don't allow to increase the lock duration for a period higher than the loan duration.

+# Multiple Cancellations of the Same Lend Offer, Triggering Repeated LendOrderDeleted and LendOrderUpdated Events
+
+### Summary
+
+A vulnerability exists in the `DebitaLendOffer-Implementation::cancelOffer` function, which allows an attacker to **cancel the same lend offer multiple times**. This occurs when the attacker first calls `addFunds` on a canceled order, and then calls `cancelOffer` again. The repeated cancellations lead to the `DebitaLendOfferFactory::emitDelete` and `DebitaLendOfferFactory::emitUpdate` functions being invoked multiple times, triggering the `LendOrderDeleted` and `LendOrderUpdated` events multiple times for the same order. This results in incorrect contract behavior and misleading event logs.
+
+### Vulnerability Details
+
+1. **Attack Flow: Repeated Cancellations via `addFunds`**:
+ - The attacker creates a lend offer via `DebitaLendOfferFactory::createLendOrder`.
+ - The attacker then calls `DebitaLendOffer-Implementation::cancelOffer` to cancel the offer.
+ - After the offer is canceled, the attacker **calls `addFunds`** on the same canceled order. The `addFunds` function does not validate whether the order is still active, so it allows the attacker to add additional funds to the canceled order.
+ - Once funds are added, the attacker can **call `cancelOffer` again** on the same order. Since the `cancelOffer` function does not check the `isActive` status, it allows the canceled order to be canceled again.
+ - This leads to the repeated triggering of the `DebitaLendOfferFactory::emitDelete` function, which causes the `LendOrderDeleted` event to be emitted multiple times for the same order, even though the order has already been canceled.
+
+2. **Incorrect Event Emissions**:
+ - The `LendOrderDeleted` event is intended to be triggered once when a lend order is deleted. However, due to the repeated cancellations, the event is incorrectly triggered multiple times for the same order.
+ - This results in **misleading event logs**, where the same order is marked as "deleted" multiple times, which could confuse external systems and users that rely on this event to track canceled orders.
+
+3. **Impact on External Systems and Protocol Integrity**:
+ - External systems that rely on the `LendOrderDeleted` event to track the status of orders may be misled into thinking that an order has been deleted multiple times. This could cause synchronization issues with external applications or state inconsistencies in those systems.
+ - Additionally, repeated emissions of the `LendOrderDeleted` event may cause **incorrect state updates** and undermine the protocol’s ability to accurately manage and track active lend offers.

+
+### Attack Path
+
+1. The attacker creates an order via `DebitaLendOfferFactory::createLendOrder`.
+2. The attacker repeatedly calls `cancelOffer`, `addFunds`, `cancelOffer`, ...
+
+
+### Impact
+
+- **Incorrect Event Emissions**: The `LendOrderDeleted` event is emitted multiple times for the same order, leading to misleading logs and inaccurate tracking of canceled orders.
+- **Protocol Integrity**: The vulnerability affects the protocol’s ability to accurately track and manage lend offers, potentially causing issues with order deletion, event emissions, and user fund management.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+1. **Prevent Multiple Cancellations**: Add a check in the `cancelOffer` function to verify if the order has already been canceled (by checking the `isActive` flag). If the order is already canceled, the function should revert and prevent any further cancellations.
+
+2. **Prevent Fund Addition to Canceled Orders**: Modify the `addFunds` function to check whether the lend offer is active before allowing additional funds to be added. This ensures that no funds can be added to a canceled order, preventing the attacker from manipulating the offer's state.
+
+3. **Correct Event Emissions**: Ensure that the `LendOrderDeleted` event is emitted only once per order. The contract should check the order’s status before emitting the event to ensure it is not triggered multiple times for the same order. The `emitDelete` function should be called only if the order is truly being deleted for the first time.

+# Incorrect Handling of owner Parameter in `changeOwner` Function
+
+## Summary
+The `changeOwner` function, as implemented in `DebitaV3Aggregator.sol`, `AuctionFactory.sol`, and `BuyOrderFactory.sol`, fails to update the contract's actual owner due to a naming conflict between the function parameter and the state variable. This bug causes the function to behave incorrectly, leading to a failure in ownership transfer.
+
+## Vulnerability Details
+## Root Cause:
+The function parameter owner shadows the state variable owner. When assigning the new owner, owner = owner, the function assigns the value of the parameter owner to itself rather than updating the state variable. Consequently, the actual state variable owner remains unchanged.
+
+## Behavior of the Bug:
+
+The first require statement `(require(msg.sender == owner, "Only owner");)` checks the new owner's address instead of the current owner's address. If the actual owner attempts to call this function, it reverts because `msg.sender` will never match the new owner's address.
+Even if the function were executed without the revert, the state variable owner would not be updated, as the assignment affects only the function-scoped parameter.
+
+## Code Snippet
+[AuctionFactory.sol](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L218-L222)

+
+``` javascript
+function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+```
+## Impact
+Ownership cannot be transferred. This issue locks critical administrative functions and halts any further development or updates that rely on ownership changes.
+
+## POC
+Enter this line into your terminal .
+```solidity
+ forge test --mt testchangeowner -vvvv
+```
+Add deployedtime variable and initalize it in your setup function with block.timestamp . Add this test case to BasicDebitaAggregator.t.sol .
+
+```javascript
+
+ uint deployedtime ;
+ function testchangeowner() public {
+ // The previous owner of contract is owner1.
+ address owner1 = DebitaV3AggregatorContract.owner();
+ address owner2 = address(0x08);
+ console.log("Old Owner of the contract is", owner1);
+ console.log("Owner want to change their role with ", owner2);
+ vm.warp(deployedtime + 7 hours);
+ // Only new owner can call changeOwner .
+ vm.startPrank(owner2);
+ DebitaV3AggregatorContract.changeOwner(owner2);
+ console.log("New Owner of the contract is", DebitaV3AggregatorContract.owner());
+ // The actual owner of the contract is not changed
+ assertEq(owner1 , DebitaV3AggregatorContract.owner());
+ }
+```
+## Recommendation
+Rename the owner parameter in the `changeOwner` function to a distinct name (e.g., _owner) to avoid shadowing the state variable:
+```solidity
+function changeOwner(address _owner) public {
+ require(msg.sender == owner, "Only owner"); // Verify current owner
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = _owner; // Update state variable with new owner
+}

+# Incorrect Comparison in `payDebt()` : Should Use `>` Instead of `>=` for Deadline Check
+
+## Summary
+In the `payDebt` function of the contract, there is a deadline check using `nextDeadline() >= block.timestamp`. This comparison should instead be using `nextDeadline() > block.timestamp` to ensure that the deadline has not already passed when the user attempts to make a payment. The current check allows the borrower to make a payment exactly at the deadline time, which may not be the intended behavior.
+
+## Vulnerability Details
+### Root Cause:
+The function compares the next deadline using >=, which permits payments exactly at the deadline time.
+In this case, if nextDeadline() is equal to block.timestamp, the payment will be allowed, even though the deadline has technically passed.
+
+## Code Snippet
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L194-L197
+
+## Expected Behavior:
+
+1. The check should ensure that the current timestamp is strictly less than the deadline to prevent payments after the deadline has passed.
+2. By using >=, the contract may allow payments at the exact deadline, which can lead to undesired behavior, especially in time-sensitive systems.
+### Issue with the Current Comparison:
+The borrower could potentially pay exactly at the deadline (when nextDeadline() equals block.timestamp), which may not align with the business logic or the intended functionality of the contract, where the payment should strictly happen before the deadline.
+## Impact
+The borrower can make payments exactly at the deadline, which may not be the intended behavior in the protocol. The payment should only be accepted if the current time is strictly before the deadline. This behavior could lead to edge-case issues with other time-dependent logic in the system, such as token transfers, fee calculations, or other contract interactions.
+## Recommendation
+To fix the issue, replace the >= operator with > in the require statement, ensuring that payments are only accepted if the deadline is strictly in the future.

+# Unsafe Usage of ERC20 `transfer` and `transferFrom` in `DebitaIncentives` Contract
+
+## Summary
+The `DebitaIncentives` contract assumes that all ERC20 tokens conform to the standard of returning a boolean (bool) value for the `transfer` and `transferFrom` functions. However, tokens like USDT deviate from this standard. This causes two key functions, `claimIncentives` and `incentivizePair`, to behave incorrectly. Transfers may fail silently, allowing operations to appear successful even if tokens are not transferred.
+## Vulnerability Details
+**claimIncentives:**
+This function attempts to transfer tokens to users. If the token does not return a boolean, the function may succeed but fail to transfer the tokens. Users will not receive their incentives, but the transaction will appear successful.
+**incentivizePair:**
+This function attempts to transfer tokens to the contract. If the token does not return a boolean, the function may fail to transfer the tokens without reverting, leaving the contract without the intended funds.
+## Code Snippets
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L203
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L268-L273
+## Impact
+The `claimIncentives` function might indicate successful transfers even if the transfer did not occur, resulting in incorrect behavior.
+The `incentivizePair` function might appear to succeed while the tokens are not transferred to the contract, leading to incorrect accounting and potential financial discrepancies.
+## Recommendation
+Use OpenZeppelin’s SafeERC20 library to handle token transfers. This library ensures compatibility with non-standard tokens like USDT by properly verifying the success of transfer and transferFrom operations.

+# Legitimate Lenders and Borrowers Will Not Be Incentivized.
+
+### Summary
+
+The `DebitaIncentives::updateFunds()` function contains a logical error that prevents legitimate lenders and borrowers from being incentivized.
+
+### Root Cause
+
+- The arises from the [DebitaIncentives::updateFunds()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L317) function:
+```solidity
+ function updateFunds(
+ infoOfOffers[] memory informationOffers,
+ address collateral,
+ address[] memory lenders,
+ address borrower
+ ) public onlyAggregator {
+ for (uint i = 0; i < lenders.length; i++) {
+ bool validPair = isPairWhitelisted[informationOffers[i].principle][
+ collateral
+ ];
+ if (!validPair) {
+@> return;
+ }
+ ------ SKIP ------
+ }
+ }
+```
+If the `i`th pair is not whitelisted, the function returns immediately, skipping updates for the subsequent pairs even if they are valid.
+
+
+### Internal pre-conditions
+
+- There are whitelisted pairs, e.g: USDC/WBTC.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Assume that two lend offers match with a borrow offer.
+ 1. The the first lender's principal is `USDC` and the second lender's principal is `USDT`.
+ 2. The borrower's collateral is `WBTC`.
+2. Suppose the `USDC/WBTC` pair is not whitelisted, but `USDT/WBTC` pair is whitelisted.
+3. When `updateFunds()` processes the first pair (index `0`), it encounters a non whitelisted pair `USDC/WBTC` and returns immediately.
+4. Consequently, the valid `USDT/WBTC` pair is not updated, and the second lender and the borrower lose incentives.
+
+
+### Impact
+
+Loss of funds because lenders and borrowers lose incentives.
+
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+It is recommended to replace the `return` statement with the `continue` to ensure the loop processes all pairs:
+```diff
+ if (!validPair) {
+- return;
++ continue;
+ }
+```
+This change ensures that the function skips invalid pairs but processes valid ones, updating the incentives correctly.

+In [`Auction.sol:118`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/auctions/Auction.sol#L118) for fee calculation, it reads the fee set by the owner of the factory [`AuctionFactory:changeAuctionFee`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L198) and gets levied to every ongoing auctions
+
+### Internal pre-conditions
+
+The `AuctionFactory.sol` owner changes the auction fee or increases the auction fee
+
+### External pre-conditions
+
+N/A
+
+### Attack Path
+
+1. Seller sets the floor amount and initial amount by doing the math with the existing auction fee of (floorAmount/currentPrice-fee)
+2. Admin increases the fee
+3. Seller gets less amount than the anticipated math in 1
+
+### Impact
+
+The seller gets less than they anticipated with a math of (floorAmount or currentPrice - fee)
+
+### PoC
+
+N/A
+
+### Mitigation
+
+Since the `auction.sol` takes a bunch of parameters during its deployment from the factory a `fee` can be taken similarly and calculated making the fee fixed for that auction. Helps sellers to price better too.

+# Rounding error in `DebitaIncentives.claimIncentives()` function.
+
+### Summary
+
+There is a rounding error in `DebitaIncentives.claimIncentives()` function.
+
+
+### Root Cause
+
+- The [DebitaIncentives.claimIncentives()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L142-L214) function contains a rounding error in calculating percents:
+```solidity
+ function claimIncentives(
+ address[] memory principles,
+ address[][] memory tokensIncentives,
+ uint epoch
+ ) public {
+ // get information
+ require(epoch < currentEpoch(), "Epoch not finished");

+ // get the total lent amount for the epoch and principle
+ uint totalLentAmount = totalUsedTokenPerEpoch[principle][epoch];
+
+ uint porcentageLent;
+
+ if (lentAmount > 0) {
+161: porcentageLent = (lentAmount * 10000) / totalLentAmount;
+ }
+
+ uint borrowAmount = borrowAmountPerEpoch[msg.sender][
+ hashVariables(principle, epoch)
+ ];
+ uint totalBorrowAmount = totalUsedTokenPerEpoch[principle][epoch];
+ uint porcentageBorrow;
+
+ require(

+ "No borrowed or lent amount"
+ );
+
+175: porcentageBorrow = (borrowAmount * 10000) / totalBorrowAmount;
+
+ for (uint j = 0; j < tokensIncentives[i].length; j++) {
+ address token = tokensIncentives[i][j];
+ uint lentIncentive = lentIncentivesPerTokenPerEpoch[principle][

+ }
+ }
+```
+As can be seen, since `porcentageLent` is less than `10000` in `L161`, a lender will lose incentives up to `0.01%`. The same problem exists in `L175`.

+### Internal pre-conditions

+### Attack Path
+
+1. Assume that a lender's lent percentage is `0.0499%`.
+2. Since `porcentageLent` is calculated as `4` (`0.04%`) in `L161`, the lender will lose about `20%` (`(0.0499 - 0.04) / 0.0499`) incentives of his own.

+# Unnecessary Formula Will Revert Extending Loans.
+
+### Summary
+
+The `DevitaV3Loan::extendLoan()` function contains a unnecessary formula that may cause an underflow in certain conditions, leading to a DOS for the function.
+
+### Root Cause
+
+- The issue lies in the [DevitaV3Loan::extendLoan()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L590-L592) function, where the following calculation is performed:
+```solidity
+ uint extendedTime = offer.maxDeadline -
+ alreadyUsedTime -
+ block.timestamp;
+```
+- The variable `extendedTime` is not used elsewhere in the function.
+- However, this calculation can underflow if `alreadyUsedTime` exceeds `offer.maxDeadline - block.timestamp`, causing the function to revert.
+
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Suppose the maximum loan duration (`offer.maxDeadline`) is 30 days.
+2. After `20 days`, the borrower attempts to extend the loan.
+3. At this point:
+ - `alreadyUsedTime = 20 days`
+ - `offer.maxDeadline - block.timestamp = 10 days`
+4. Since `20 days > 10 days`, the subtraction in the formula underflows, causing the function to revert.
+
+
+### Impact
+
+- The borrower cannot extend the loan, breaking the contract's functionality.
+- This results in borrower liquidation, leading to a potential loss of funds.
+
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+It is recommended to remove the unnecessary formula.

+# An attacker can wipe the orderbook in buyOrderFactory.sol
+
+### Summary
+
+A malicious actor can wipe the complete buy order orderbook in `buyOrderFactory.sol`. The attack - excluding gas costs - does not bear any financial burden on the attacker. As a result of the exploit, the orderbook will be temporarily inaccessible in the factory, leading to a DoS state in buy order matching, and in closing and selling existing positions.
+
+### Root Cause
+
+The function `sellNFT(uint receiptID)` lacks reentrancy protection:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L92
+
+### Internal pre-conditions
+
+N/A
+
+### External pre-conditions
+
+N/A
+
+### Attack Path
+
+1. Attacker calls `createBuyOrder(address _token, address wantedToken, uint _amount, uint ratio)` with exploit contract supplied in parameter `wantedToken`
+2. Attacker calls `sellNFT(uint receiptID)` which triggers the exploit sequence
+3. Exploit contract will reenter `sellNFT` multiple times, triggering a cascade of buy order deletions
+
+### Impact
+
+The orderbook in `buyOrderFactory.sol` will be inaccessible. The function `getActiveBuyOrders(uint offset, uint limit)` is used by off-chain services to gather buy order data - this data will be temporarily blocked. Deleting existing buy orders (`deleteBuyOrder()`) and selling NFTs (`sellNFT(uint receiptID)`) will also be temporarily blocked until the issue is resolved manually. Issue can be resolved manually by:
+- Opening dummy buy orders with very little collateral
+- Closing/selling positions on existing "legit" orders
+
+### PoC
+
+Note: the PoC is somewhat hastily developed as the audit deadline is quite short relative to the project scope. Executing the PoC with the verbose flag (forge test -vvvv) will show that deletion is triggered multiple times.

+# Active Order Count Manipulation Through Multiple Cancellations
+
+### Summary
+
+Malicious users can manipulate the `activeOrdersCount` in the `DebitaLendOfferFactory` contract by exploiting a flaw in the interaction between cancelOffer() and addFunds() functions. The ability to call addFunds on a canceled lend offer will cause a logical flaw that allows repeated calls to cancelOffer. This reduces the activeOrdersCount to zero, resulting in underflow issues. The underflow creates two significant problems:
+1. Other lenders cannot cancel their offers.
+2. Matching lending offers in acceptLendingOffer fails when all available amounts used
+
+
+### Root Cause
+
+The root cause stems from two key design flaws:
+1. The cancelOffer() function in `DebitaLendOffer-Implementation.sol `sets isActive = false but doesn't prevent subsequent calls to addFunds()
+2. The addFunds() function only checks for owner or loan sender permissions but doesn't verify the offer's active status
+
+```solidity
+ function cancelOffer() public onlyOwner nonReentrant {
+ uint availableAmount = lendInformation.availableAmount;
+ lendInformation.perpetual = false;
+ lendInformation.availableAmount = 0;
+ require(availableAmount > 0, "No funds to cancel");
+ isActive = false;
+
+ SafeERC20.safeTransfer(
+ IERC20(lendInformation.principle),
+ msg.sender,
+ availableAmount
+ );
+ IDLOFactory(factoryContract).emitDelete(address(this));
+ IDLOFactory(factoryContract).deleteOrder(address(this));
+ // emit canceled event on factory
+ }
+```
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L157
+
+This allows a malicious user to:
+- Cancel an offer (decreasing activeOrdersCount)
+ - Add new funds to the cancelled offer
+- Cancel again (further decreasing activeOrdersCount)
+- Repeat until activeOrdersCount is 0
+
+
+```solidity
+function deleteOrder(address _lendOrder) external onlyLendOrder {
+ ...
+ activeOrdersCount--;
+}
+```
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207
+
+### Internal pre-conditions
+
+1. Attacker must be the owner of a lending offer
+2. The lending offer must have been successfully created through the factory
+3. The offer must have available funds to cancel initially
+4. The attacker must have additional funds to add after cancellation
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. A user creates a lend offer and cancels it by calling cancelOffer, which reduces activeOrdersCount via deleteOrder.
+2. The user adds funds to the canceled offer using addFunds.
+3. The user repeats step 1, reducing activeOrdersCount further with each cycle.
+4. When activeOrdersCount underflows:
+- Other lenders are unable to cancel their offers.
+- Matching offers in acceptLendingOffer fails.
+
+### Impact
+
+Other Lenders unable to cancel their offers due to the underflow in activeOrdersCount.
+acceptLendingOffer() also calls deleteOrder() when an offer's availableAmount is 0. This prevents new lending matches from being processed
+
+### PoC
+
+Inside PerpetualMixPrinciples.t.sol test file
+
+```solidity
+ function testOrderCountUnderflow() public {
+ assertEq(
+ DLOFactoryContract.activeOrdersCount(),3);
+
+ vm.startPrank(secondLender);
+ wETHContract.approve(address(SecondLendOrder), 5e18);

+# Borrower can force lenders to wait till `maxDeadline` to claim collaterals , if he fails to repay the debt.
+
+### Summary
+
+The `extendLoan` function extends the loan repay time to lender's `maxDeadline` . However, if the borrower not want to repay loan for that lender , than by leveraging the `extendLoan` function, the borrower might restrict lender to call `createAuctionForCollateral` till `maxDeadline`.
+
+```solidity
+require(nextDeadline() < block.timestamp, "Deadline not passed");
+```
+
+### Root Cause
+
+The borrower offer having 1 day duration and the lender offer having min duration as 1 day and max duration as 100 days is matched by the aggregator and loan created.
+
+So if the borrower is not want/able to repay the loan before 1 day, then he might call the `extendLoan` function and can increase time for the lenders to claim the borrower's collateral till the lenders `maxDuration(maxDeadline)`.
+
+```solidity

+# Permanent Loss of Lender NFT Due to Improper Claim Flow
+
+### Summary
+
+When a lender attempts to claim NFT collateral, their lender NFT can be burned without receiving any assets in return if specific conditions aren't met. This results in a permanent loss of claim rights and potential value locked in the protocol.
+
+
+### Root Cause
+
+The vulnerability stems from an improper flow control in the claimCollateralAsLender function. If calleteral is NFT `claimCollateralAsLender` calls `claimCollateralAsNFTLender` function.
+The `claimCollateralAsNFTLender` function does not revert if neither of its conditions (auctionInitialized or a single accepted offer) is satisfied. Instead, it simply returns false, leaving the lender without their claim.
+
+```solidity
+function claimCollateralAsLender(uint lenderID) public nonReentrant returns (bool) {
+ // Burns NFT immediately without checking if claim will succeed
+ ownershipContract.burn(offer.lenderID);
+
+ // Checks conditions after burning
+ if (m_loan.auctionInitialized) {
+ // auction claim logic
+ } else if (m_loan._acceptedOffers.length == 1 && !m_loan.auctionInitialized) {
+ // single lender claim logic
+ }
+ return false; // Returns false if conditions not met, but NFT is already burned
+}
+```
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L374
+
+### Internal pre-conditions
+
+1. The collateral must be an NFT
+2. The loan must have multiple lenders (_acceptedOffers.length > 1)
+3. The auction must not be initialized
+4. A lender must attempt to claim their collateral portion

+# Blacklisted borrower can block loan liquidation, causing bad debt for the protocol
+
+### Summary
+
+The lack of handling for blacklisted addresses during USDC transfers will cause failed loan liquidations for the protocol, as transactions revert when transferring USDC to a blacklisted borrower.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L524-L543
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L496-L522
+
+### Root Cause
+
+In `DebitaV3Loan.sol`, during the collateral claim and liquidation processes, the contract attempts to transfer USDC (or any ERC20 token) to the borrower without checking if the borrower is blacklisted by the USDC contract. If the borrower is blacklisted, the transfer will revert, preventing the completion of the liquidation or collateral claim.
+
+### Internal pre-conditions
+
+1.Borrower is blacklisted: The borrower's address has been blacklisted by the USDC token contract.
+2.Active loan: The borrower has an active loan that is due for liquidation or collateral return.
+
+### External pre-conditions
+
+USDC token contract blacklist: The USDC token contract has blacklisted the borrower's address, disallowing transfers to that address.
+
+### Attack Path
+
+1. Loan due for liquidation: The borrower's loan becomes due for liquidation, or the borrower attempts to claim their collateral after repayment.
+2. Contract attempts transfer: The DebitaV3Loan contract calls a function to transfer USDC to the borrower's address.
+3. Transfer reverts: The transfer fails and reverts because the USDC contract blocks transfers to blacklisted addresses.
+4. Liquidation blocked: The failed transfer causes the entire transaction to revert, preventing loan liquidation or collateral return.
+
+### Impact
+
+The protocol cannot liquidate the loan or return collateral, leading to potential bad debt and locked funds. Lenders may not recover their funds, and the protocol's financial stability is at risk.
+
+### PoC
+
+```solidity
+// Assume borrower is blacklisted by USDC
+address blacklistedBorrower = /* blacklisted address */;
+DebitaV3Loan loanContract = DebitaV3Loan(/* loan contract address */);
+
+// Borrower attempts to claim collateral
+// This will revert due to transfer to a blacklisted address
+loanContract.claimCollateralERC20AsBorrower(/* indexes */);
+
+// During liquidation, the contract attempts to transfer USDC
+// to the blacklisted borrower, causing the transaction to revert
+```
+
+### Mitigation
+
+Implement Blacklist Checks: Before performing transfers, check if the recipient address is blacklisted by USDC. If so, handle the situation by:
+- Holding the funds in escrow until the borrower is removed from the blacklist.
+- Allowing the borrower to specify an alternate address that is not blacklisted.
+- Graceful Failure Handling: Modify contract logic to handle transfer failures without reverting the entire transaction. For example:
+Use a try-catch block when performing the transfer.
+- If the transfer fails, record the failed transfer and allow the rest of the liquidation process to continue.
+Use Alternative Tokens or Mechanisms:
+- Allow settlements in alternative tokens that do not have blacklist features.
+- Provide options for borrowers to claim collateral in a different form or through a different method.

+# Attacker can disproportionately claim incentives, reducing rewards for legitimate users
+
+### Summary
+
+The lack of time-weighted calculations in the incentive distribution will cause unfair over-allocation of incentives to attackers, as they can deposit large amounts just before an epoch ends to claim a significant share of rewards.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L142-L214
+
+### Root Cause
+
+In `DebitaIncentives.sol`, the `claimIncentives` function calculates incentives based solely on the total amount lent or borrowed during an epoch, without accounting for the duration of participation. This allows users to manipulate incentive distribution by contributing large amounts near the epoch's end.
+
+
+
+### Internal pre-conditions
+
+1. Attacker deposits a large amount: An attacker needs to deposit a significant amount of tokens into the lending protocol shortly before the epoch ends.
+2. Incentive calculation based on total amounts: The contract uses the total lent or borrowed amounts during the epoch for incentive distribution without considering time-weighting.
+
+### External pre-conditions
+
+No time-weighting mechanism: The protocol lacks integration with any external time-weighting mechanisms for incentive calculations.
+
+### Attack Path
+
+1. Attacker waits until just before an epoch is about to end.
+2. Attacker calls the lend function to deposit a large amount of tokens into the protocol.
+3. Epoch ends, and incentives are calculated based on total amounts lent during the epoch.
+4. Attacker's large late deposit skews the incentive distribution in their favor.
+5. Attacker calls the claimIncentives function to claim a disproportionate share of incentives.
+6. Legitimate users receive significantly fewer incentives than expected.
+
+### Impact
+
+Legitimate users suffer a reduction in expected incentive rewards due to the attacker's manipulation, receiving a smaller share of incentives despite their longer participation. The attacker gains an unfair portion of the incentives, undermining the protocol's reward system.
+
+### PoC
+
+```solidity
+// Assume current epoch is about to end in a few blocks
+uint currentEpoch = incentivesContract.currentEpoch();
+
+// Step 1: Legitimate users have lent tokens throughout the epoch
+// User A lent 100 tokens at epoch start
+// User B lent 200 tokens at epoch start
+
+// Step 2: Attacker lends 10,000 tokens just before epoch ends
+lendingContract.lend(10000 ether);
+
+// Step 3: Epoch ends, incentives are calculated
+// Total lent amount: 10,300 tokens
+// Attacker's share: (10,000 / 10,300) ≈ 97%
+
+// Step 4: Attacker claims incentives
+address[] memory principles = new address[](1);
+principles[0] = address(principleToken);
+
+address[][] memory tokensIncentives = new address[][](1);
+tokensIncentives[0] = new address[](1);
+tokensIncentives[0][0] = address(incentiveToken);
+
+incentivesContract.claimIncentives(principles, tokensIncentives, currentEpoch);
+
+// Attacker receives 97% of the incentives for the epoch
+```
+
+### Mitigation
+
+Implement time-weighted calculations for incentive distribution:
+
+- Modify the incentive calculation to consider both the amount and the duration of participation within an epoch.
+- Track the time-weighted lending amounts for each user.
+- Adjust the getLenderIncentives function to use time-weighted amounts when calculating the incentives.
+Alternatively, set a maximum cap on incentives per user per epoch to prevent any single participant from claiming an excessive share.
+
+
+Time-weighted Incentive Calculation:
+```solidity
+// New mapping to track the time-weighted lent amount per user per epoch
+mapping(address => mapping(bytes32 => uint)) public timeWeightedLentAmountPerUserPerEpoch;
+
+// Mapping to store the timestamp when the user lent the funds
+mapping(address => mapping(bytes32 => uint)) public lentTimestampPerUserPerEpoch;
+...
+
+function updateFunds(
+ // ... existing parameters ...
+) public returns (bool) {
+ // ... existing logic ...
+
+ // For each lender
+ for (uint i = 0; i < lenders.length; i++) {
+ uint principleHash = hashVariables(principle, _currentEpoch);
+
+ // Record the time the funds were lent
+ lentTimestampPerUserPerEpoch[lenders[i]][principleHash] = block.timestamp;
+
+ // Update the lent amount
+ lentAmountPerUserPerEpoch[lenders[i]][principleHash] += informationOffers[i].principleAmount;
+ }
+
+ // ... existing logic ...
+}
+...
+```
+Calculating Time-weighted Amount:
+Modify getLenderIncentives to calculate the time-weighted lent amount.
+
+```solidity
+function getLenderIncentives(
+ address lender,
+ address principle,
+ address incentiveToken,
+ uint epoch
+) public view returns (uint amountToSend) {
+ uint principleHash = hashVariables(principle, epoch);
+ uint totalTimeWeightedLentAmount = totalTimeWeightedTokenPerEpoch[principle][epoch];
+ uint userTimeWeightedLentAmount = timeWeightedLentAmountPerUserPerEpoch[lender][principleHash];
+ uint totalIncentive = incentivizedPerEpoch[principle][incentiveToken][epoch];
+ amountToSend =
+ (userTimeWeightedLentAmount * totalIncentive) /
+ totalTimeWeightedLentAmount;
+}
+
+```
+Calculating Time-weighted Amount Upon Epoch End:
+At the end of the epoch, calculate the time-weighted amounts.
+```solidity
+function finalizeEpoch(uint epoch) public {
+ // Only callable by owner or trusted party
+ // For each user, calculate the time-weighted lent amount
+ for (uint i = 0; i < users.length; i++) {
+ address lender = users[i];
+ uint principleHash = hashVariables(principle, epoch);
+ uint lentAmount = lentAmountPerUserPerEpoch[lender][principleHash];
+ uint lentTimestamp = lentTimestampPerUserPerEpoch[lender][principleHash];
+
+ // Calculate the duration the funds were lent
+ uint lendingDuration = epochEndTime[epoch] - lentTimestamp;
+
+ // Calculate the time-weighted amount

+# Missing check for stale data might result in inaccurate oracle responses
+
+### Summary
+
+The Chainlink oracle implementation does not verify the staleness of the price feed responses. Consequently, if a feed for an asset becomes inactive or outdated, the system may rely on incorrect price data for calculations.
+
+### Root Cause
+
+The `DebitaChainlink::getThePrice` function fetches asset prices by calling the `latestRoundData` function on the price feed contract. However, this implementation only retrieves the price data without verifying the `updatedAt` timestamp to ensure it is recent. As a result, stale data could inadvertently be used.
+
+```javascript
+function getThePrice(address tokenAddress) public view returns (int) {
+ // falta hacer un chequeo para las l2
+ address _priceFeed = priceFeeds[tokenAddress];
+ require(!isPaused, "Contract is paused");
+ require(_priceFeed != address(0), "Price feed not set");
+ AggregatorV3Interface priceFeed = AggregatorV3Interface(_priceFeed);
+
+ // if sequencer is set, check if it's up
+ // if it's down, revert
+ if (address(sequencerUptimeFeed) != address(0)) {
+ checkSequencer();
+ }
+ (, int price, , , ) = priceFeed.latestRoundData(); //@audit missing check for stale data
+
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+ require(price > 0, "Invalid price");
+ return price;
+}

+# "Improper Handling of deleteOrder Will Disrupt Aggregator Services and Lock Lender Assets"
+
+### Summary
+
+Improper handling of the **`deleteOrder`** function may lead to abnormal states, preventing the Aggregator from providing lending services. This could also cause the lender to be unable to use the `cancelOffer` function to withdraw their assets, resulting in locked assets.
+
+### Root Cause
+
+In the **DebitaLendOffer** contract, the **cancelOffer** function will send the remaining **lendInformation.availableAmount** and call **DebitaLendOfferFactory.deleteOrder** to delete its own **lendOrder**. The specific logic is as follows:
+
+```solidity
+ function deleteOrder(address _lendOrder) external onlyLendOrder {
+ uint index = LendOrderIndex[_lendOrder];
+ LendOrderIndex[_lendOrder] = 0;
+
+ // switch index of the last borrow order to the deleted borrow order
+ allActiveLendOrders[index] = allActiveLendOrders[activeOrdersCount - 1];
+ LendOrderIndex[allActiveLendOrders[activeOrdersCount - 1]] = index;
+
+ // take out last borrow order
+
+ allActiveLendOrders[activeOrdersCount - 1] = address(0);
+
+ activeOrdersCount--;
+ }
+```
+
+In the **deleteOrder** function, **LendOrderIndex[_lendOrder]** is set to 0. However, if **deleteOrder** is called again, even if **LendOrderIndex[_lendOrder]** is 0, it will still swap **allActiveLendOrders[0]** with **allActiveLendOrders[activeOrdersCount-1]** and clear **allActiveLendOrders[0]**, which can result in the deletion of data that does not belong to the **lendOrder**. If **deleteOrder** is called repeatedly, it will clear all entries in **activeOrdersCount**, causing other users' data to be erased, and all data in **allActiveLendOrders** will be set to **address(0)**. This will cause **Aggregator** to fail when calling **DebitaLendOffer.acceptLendingOffer**, for the following reason:
+
+```solidity
+ function acceptLendingOffer(
+ uint amount
+ ) public onlyAggregator nonReentrant onlyAfterTimeOut {
+ LendInfo memory m_lendInformation = lendInformation;
+ uint previousAvailableAmount = m_lendInformation.availableAmount;
+ require(
+ amount <= m_lendInformation.availableAmount,
+ "Amount exceeds available amount"
+ );
+ require(amount > 0, "Amount must be greater than 0");
+
+ lendInformation.availableAmount -= amount;
+ SafeERC20.safeTransfer(
+ IERC20(m_lendInformation.principle),
+ msg.sender,
+ amount
+ );
+
+ // offer has to be accepted 100% in order to be deleted
+ if (
+ lendInformation.availableAmount == 0 && !m_lendInformation.perpetual
+ ) {
+ isActive = false;
+ IDLOFactory(factoryContract).emitDelete(address(this));
+ IDLOFactory(factoryContract).deleteOrder(address(this));
+ } else {
+ IDLOFactory(factoryContract).emitUpdate(address(this));
+ }
+
+ // emit accepted event on factory
+ }
+```
+
+When **`lendInformation.availableAmount == 0 && !m_lendInformation.perpetual`** is satisfied, the call to **`IDLOFactory(factoryContract).deleteOrder(address(this));`** will revert, because **activeOrdersCount** has already been set to 0, preventing the Aggregator from functioning properly.
+
+Additionally, when the lender calls **cancelOffer** to withdraw their assets, the operation will also fail, causing the lender's assets to be locked.

+# Incorrect Call Order Will Result in Lender Losing All Loan Interest
+
+### Summary
+
+Incorrect Call Order Will Result in Lender Losing All Loan Interest
+
+### Root Cause
+
+When the borrower calls **DebitaV3Loan.extendLoan**, if **lendInfo.perpetual = false**, interest will be paid to the lender, i.e., **`loanData._acceptedOffers[i].interestToClaim += interestOfUsedTime - interestToPayToDebita;`**.
+
+If the borrower exceeds the repayment date and the lender calls **DebitaV3Loan.claimCollateralAsLender** to withdraw the borrower's collateral, **`ownershipContract.burn(offer.lenderID);`** will be executed, removing the lender's permission. At this point, if the lender has not yet claimed the interest, calling **claimDebt** to withdraw the interest will cause a revert. The lender's loan interest will never be able to be claimed, leading to asset loss.
+
+```solidity
+ function claimDebt(uint index) external nonReentrant {
+ IOwnerships ownershipContract = IOwnerships(s_OwnershipContract);
+ infoOfOffers memory offer = loanData._acceptedOffers[index];
+
+ require(
+ ownershipContract.ownerOf(offer.lenderID) == msg.sender,
+ "Not lender"
+ );
+ // check if the offer has been paid, if not just call claimInterest function
+ if (offer.paid) {
+ _claimDebt(index);
+ } else {
+ // if not already full paid, claim interest
+ claimInterest(index);
+ }
+ }
+```
+
+In **claimDebt**, it will check **`require(ownershipContract.ownerOf(offer.lenderID) == msg.sender, "Not lender");`**.
+
+Since **claimCollateralAsLender** destroys the lender's permission, **claimDebt** will never succeed, causing the user to lose interest.
+

+# DebitaV3Aggregator::changeOwner() doesn't update owner storage variable
+
+### Summary
+
+`changeOwner()` is supposed to allow the Debita team to change the `owner` of the `DebitaV3Aggregator` contract. The problem is that the input param (`owner`) has the name as the storage variable `owner`. When the current owner calls changeOwner(), the function will always revert because the new owner address will be different than msg.sender (the current owner).
+
+### Root Cause
+
+The owner input parameter has the same name as the owner storage variable:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682-L686
+
+### Internal pre-conditions
+
+n/a
+
+### External pre-conditions
+
+n/a
+
+### Attack Path
+
+1. `owner` of `DebitaAggregatorV3` calls `changeOwner(newOwner)` passing in the address of the new owner
+2. `changeOwner(newOwner)` reverts at this line, `require(msg.sender == owner, "Only owner");`, because `owner` here is being interpreted by Solidity as the local variable `owner`, not the storage variable `owner`.
+3. `changeOwner` can be called by anyone, but nothing occurs other than the input param setting it's value to itself.
+
+### Impact
+
+The protocol can't update owner in DebitaV3Aggregator.
+
+### PoC
+
+Add to any Foundry `/test/` file and run:
+`forge test --mt testChangeOwner`
+
+```solidity
+//SPDX-License-Identifier: MIT
+pragma solidity ^0.8.0;
+
+import "forge-std/Test.sol";
+
+contract Aggregator {
+
+ uint deployedTime = 99999999999;
+
+ address public owner;
+
+ constructor() {
+ owner = msg.sender;
+ }
+
+ function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+}
+
+contract BaseTest is Test {
+ address owner = makeAddr("owner");
+ Aggregator aggregator;
+
+ function setUp() public {
+ vm.startPrank(owner);
+ aggregator = new Aggregator();
+ vm.stopPrank();
+ }
+
+ function testChangeOwner() public {
+ address newOwner = makeAddr("newOwner");
+
+ vm.startPrank(owner);
+ assertEq(aggregator.owner(), owner);
+ vm.expectRevert();
+ aggregator.changeOwner(newOwner);
+ vm.stopPrank();
+ }
+}
+```
+
+### Mitigation
+
+Update changeOwner to the following:
+```solidity
+
+function changeOwner(address _owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = _owner;

+# `DebitaLendOfferFactory::createLendOrder` allows creation of lend orders with zero principal value
+
+### Summary
+
+
+The `createLendOrder` function in `DebitaLendOfferFactory` does not validate that the principal amount is positive. This allows malicious users to repeatedly create lend orders with zero principal value.
+
+As a result, the system will emit unnecessary `LendOrderCreated` events, which could affect bots that listen for these events to trigger the `DebitaV3Aggregator::matchOffersV3` function. Additionally, the `allActiveLendOrders` list will be populated with these invalid orders, which cannot be matched or used, leading to wasted resources and potential performance issues.

+1. The attacker calls `createLendOrder`, passing zero as the `_startedLendingAmount` parameter.
+
+### Impact
+
+1. **Unnecessary Event Emissions**: By allowing zero-value lend orders, the system will emit `LendOrderCreated` events for invalid orders. This can overwhelm event listeners (such as bots), leading to wasted processing power and potential delays in handling legitimate events.
+
+2. **Cluttering Active Orders**: The `allActiveLendOrders` list will be populated with zero-value orders that cannot be matched, creating unnecessary clutter. This can degrade the performance of the system, especially if the list grows large, as it makes it harder to process and match valid lend offers.
+
+3. **Resource Wastage**: Invalid orders consume blockchain resources (e.g., gas for transaction execution, storage for maintaining order data) without providing any actual value to the system. This could increase transaction costs and negatively affect the efficiency of the platform.
+
+4. **Potential Exploitation**: Although not directly exploitable, repeatedly creating zero-value orders could be used by an attacker to spam the system, potentially causing congestion, denial of service, or disrupting the operation of dependent services like bots and aggregators.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Add a validation check to ensure the `_startedLendingAmount` is greater than zero, potentially setting a minimum required value.

+# DoS on `extendLoan()` Due to an Underflow
+
+### Summary
+
+In the `DebitaV3Loan.sol::extendLoan()` function, bounding the new protocol fee to the minimum value can result in an underflow.
+
+When creating a loan, the default duration is the one specified by the borrower. If the borrower decides to extend the loan, the duration is extended to the `maxDuration` of each accepted lend offer, with each offer having its own individual deadline.
+
+Within the `extendLoan()` function, the protocol calculates the fee (0.04% per day) based only on the extended duration of each offer, as the initial duration fee was already deducted when the offers were matched. After computing the fee for the `maxDuration` of each lend offer, it is bounded between the maximum and minimum permissible values (0.2% - 0.8%).
+
+The issue arises when the fee is incorrectly bounded to the minimum value. Instead of being set to 0.2%, it is bounded to the `feePerDay` value (0.04%), which can cause an underflow when calculating the `missingBorrowFee` value in the subsequent line:
+
+```solidity
+ function extendLoan() public {
+
+ // Function code ...
+
+ for (uint i; i < m_loan._acceptedOffers.length; i++) {
+
+ // Function code ...
+
+ uint misingBorrowFee;
+
+ // if user already paid the max fee, then we dont have to charge them again
+ if (PorcentageOfFeePaid != maxFee) {
+
+ uint feeOfMaxDeadline = ((offer.maxDeadline * feePerDay) /
+ 86400);
+ if (feeOfMaxDeadline > maxFee) {
+ feeOfMaxDeadline = maxFee;
+>> } else if (feeOfMaxDeadline < feePerDay) {
+>> feeOfMaxDeadline = feePerDay;
+ }
+
+>> misingBorrowFee = feeOfMaxDeadline - PorcentageOfFeePaid;
+ }
+ uint principleAmount = offer.principleAmount;
+ uint feeAmount = (principleAmount * misingBorrowFee) / 10000;
+
+ // Function code ...
+ }
+ }
+```
+
+
+### Root Cause
+
+In [DebitaV3Loan.sol:606](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L606), an incorrect minimum bounding value is used.

+# When a loan is extended a lender may loose part of the interest he is owed
+
+### Summary
+
+The ``DebitaV3Loan`` contract allows borrowers to extend their loan, if the lend offers allow it. For example if the initial duration set in the borrow offer was 10 days, but the max duration of the lend orders that were matched with the borrow order is 30 days, in a later date the borrower may decide to extend his loan by calling the [extendLoan()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L547-L664) function:
+```solidity
+ function extendLoan() public {
+ ...
+
+ if (
+ lendInfo.perpetual && lendInfo.owner == currentOwnerOfOffer
+ ) {
+ IERC20(offer.principle).approve(
+ address(lendOffer),
+ interestOfUsedTime - interestToPayToDebita
+ );
+ lendOffer.addFunds(
+ interestOfUsedTime - interestToPayToDebita
+ );
+ } else {
+ loanData._acceptedOffers[i].interestToClaim +=
+ interestOfUsedTime -
+ interestToPayToDebita;
+ }
+ loanData._acceptedOffers[i].interestPaid += interestOfUsedTime;
+ }
+ }
+ Aggregator(AggregatorContract).emitLoanUpdated(address(this));
+ }
+```
+In the [extendLoan()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L547-L664) function there are a couple of calculation that calculate the extra fees the borrower has to pay, one of them is the interest that has been accrued since the loan was created. As can be seen from the code snippet above the borrower transfers the accrued interest and the ``interestToClaim`` and the ``interestPaid`` fileds for the lend offer are increased. Or if the lend order is perpetual the funds are directly transferred to the lend order. However when a borrower repays a certain lend order via the [payDebt()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L186-L257) function, the previous interestToClaim is disregarded:
+```solidity
+ function payDebt(uint[] memory indexes) public nonReentrant {
+ ...
+ // if the lender is the owner of the offer and the offer is perpetual, then add the funds to the offer
+ if (lendInfo.perpetual && lendInfo.owner == currentOwnerOfOffer) {
+ loanData._acceptedOffers[index].debtClaimed = true;
+ IERC20(offer.principle).approve(address(lendOffer), total);
+ lendOffer.addFunds(total);
+ } else {
+ loanData._acceptedOffers[index].interestToClaim =
+ interest -
+ feeOnInterest;
+ }
+
+ SafeERC20.safeTransferFrom(
+ IERC20(offer.principle),
+ msg.sender,
+ feeAddress,
+ feeOnInterest
+ );
+
+ loanData._acceptedOffers[index].interestPaid += interest;
+ }
+ ...
+ }
+```
+
+As can be seen from the code snippet above if for example 2 days have passed since the borrower extended the loan, and now he repays the certain lend offer, the ``interestToClaim`` will be set to the new interest, which is the interest accrued for the 2 days that passed. Lets say that 10 days have passed since the loan was created, then the borrower extended the loan, 2 more days passed and he repaid a certain lend order. That lend order will get interest only for 2 days, essentially loosing the interest for 10 days. Lenders may call the [claimDebt()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L271-L286) function, once a loan have been extended in order to collect their interest up to that moment, however lenders are not expected to track if loans have been extended, and take action. There is also the possibility of a malicious borrower, who extends the loan and immediately repays the lend orders, this way all lenders will receive 0 interest, and the interest that they should have received will be locked in the contract forever. Depending on the amounts of the loan, the APR, and the duration the losses may be devastating. Essentially lenders would have given their money to someone expecting a certain return, but after not having access to their funds for a duration of time, they won't receive any return in the form of interest, thus the high severity.
+
+### Root Cause

+In the [payDebt()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L186-L257) function, the ``interestToClaim`` is set to the latest calculated interest,
+```solidity
+loanData._acceptedOffers[index].interestToClaim =
+ interest -
+ feeOnInterest;
+```
+which doesn't take into consideration any previously generated interest.
+
+### Internal pre-conditions
+
+1. The borrower extends the loan
+2. Either the lenders don't pay attention to the fact that the loan has been extended and they don't claim their interest before their lend offer is repaid, or the borrower is malicious and directly repays all the lend offers, after he has extended the loan.

+# Borrower Can Avoid Paying Interest In Certain Scenarios
+
+### Summary
+
+The function `DebitaV3Loan::calculateInterestToPay()` calculates the interest the borrower must pay to the lender, based on the APR specified in the associated lend offer:
+```solidity
+function calculateInterestToPay(uint index) public view returns (uint) {
+ infoOfOffers memory offer = loanData._acceptedOffers[index];
+ uint anualInterest = (offer.principleAmount * offer.apr) / 10000;
+ // check already duration
+ uint activeTime = block.timestamp - loanData.startedAt;
+ uint minimalDurationPayment = (loanData.initialDuration * 1000) / 10000;
+ uint maxDuration = offer.maxDeadline - loanData.startedAt;
+ if (activeTime > maxDuration) {
+ activeTime = maxDuration;
+ } else if (activeTime < minimalDurationPayment) {
+ activeTime = minimalDurationPayment;
+ }
+
+>> uint interest = (anualInterest * activeTime) / 31536000;
+
+ // subtract already paid interest
+ return interest - offer.interestPaid;
+ }
+```
+#### Interest Calculation Vulnerability
+
+Within the function, interest is calculated by multiplying the annual interest rate by the active time of the loan and dividing the result by the number of seconds in a year. However, this calculation can be manipulated by the borrower. If the product of the annual interest rate and the active time of the loan is smaller than the number of seconds in a year, the calculated interest rounds down to zero. This allows the borrower to avoid paying any interest.
+
+This issue can be exploited by matching orders with minimum amounts and corresponding durations and APRs. For example:
+
+- **Duration**: 30 days
+- **Amount Lent**: 0.0001 cbBTC (~8 USD)
+- **APR**: 1%
+
+If the borrower repays on the 3rd day of the loan, the calculated interest would round down to zero, resulting in no interest being paid.
+
+>*Scenario details on attack path section*
+
+### Root Cause
+
+The [interest calculation](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L734) rounds down the resulting value.
+
+### Internal pre-conditions
+
+- Lending tokens with few decimals but high value (cbBTC).
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+#### Lend Offer by Alice:
+- **Available Amount**: 3 cbBTC
+- **Min Duration**: 30 days
+- **APR**: 1%
+- **Collateral Accepted**: USDC
+
+#### Borrow Offer by Bob:
+- **Available Amount**: 1000 USDC
+- **Duration**: 30 days
+- **Max APR**: 1%
+- **Principle Accepted**: cbBTC
+
+#### Bob Match with Alice:
+- **Lend Amount**: 0.0001 cbBTC (~8 USD)
+- **Duration of the Loan**: 30 days
+- **APR**: 1%
+
+### Repayment Scenario:
+After 3 days (10% of the loan duration) the borrower repays the debt, which should reduce the interest to 0.
+Inside the `calculateInterestToPay(index)` function:
+- **`annualInterest`**: `100` (`(principleAmount * offer.APR) / 10000`).
+- **`activeTime`**: `259200` seconds (3 days).
+- **`interest`**: `(100 * 259200) / 31536000 = 0`.

+# In certain scenarios borrowers will pay more fees for extending their loans than they are supposed to.
+
+### Summary
+
+The ``DebitaV3Loan.sol`` contract allows borrowers to extend their loan by calling the [extendLoan()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L547-L664) function, which calculates several fees, including a fee that has to be paid to the DebitaFianance team for extending the loan for a certain time:
+```solidity
+ function extendLoan() public {
+ ...
+ // calculate fees to pay to us
+ uint feePerDay = Aggregator(AggregatorContract).feePerDay();
+ uint minFEE = Aggregator(AggregatorContract).minFEE();
+ uint maxFee = Aggregator(AggregatorContract).maxFEE();
+ uint PorcentageOfFeePaid = ((m_loan.initialDuration * feePerDay) /
+ 86400);
+ // adjust fees
+
+ if (PorcentageOfFeePaid > maxFee) {
+ PorcentageOfFeePaid = maxFee;
+ } else if (PorcentageOfFeePaid < minFEE) {
+ PorcentageOfFeePaid = minFEE;
+ }
+
+ // calculate interest to pay to Debita and the subtract to the lenders
+
+ for (uint i; i < m_loan._acceptedOffers.length; i++) {
+ ...
+ if (PorcentageOfFeePaid != maxFee) {
+ // calculate difference from fee paid for the initialDuration vs the extra fee they should pay because of the extras days of extending the loan. MAXFEE shouldnt be higher than extra fee + PorcentageOfFeePaid
+@here -> uint feeOfMaxDeadline = ((offer.maxDeadline * feePerDay) / 86400);
+ if (feeOfMaxDeadline > maxFee) {
+ feeOfMaxDeadline = maxFee;
+ } else if (feeOfMaxDeadline < feePerDay) {
+ feeOfMaxDeadline = feePerDay;
+ }
+
+ misingBorrowFee = feeOfMaxDeadline - PorcentageOfFeePaid;
+ }
+ uint principleAmount = offer.principleAmount;
+ uint feeAmount = (principleAmount * misingBorrowFee) / 10000;
+
+ SafeERC20.safeTransferFrom(

+ }
+```
+When a borrower creates a borrow order, he sets a duration which is the initial duration of the loan. The Lenders set a min and max duration, in order for the borrow order and lend orders to be matched the duration set by the borrower has to be between the min and max durations specified by the lender. However when the borrow and lend offers are matched, the ``offer.maxDeadline`` set for each offer is the sum of the current block.timestamp and the maxDuration specified by the lender, as can be seen on the following line in the [DebitaV3Aggregator::matchOffersV3()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L511) function. Now as can be seen from the above code snippet when ``feeOfMaxDeadline`` is calculated it will divide the block.timestamp of the loan creation + the maxDuration specified by the lender, by 86_400 seconds(1 day), which will results in hundreds of days that have to be multiplied by a certain fee. It is true that the fee is capped, however the borrower will still have to pay more fees than he is supposed to, for a loan extension part of which he won't be able to use, as the loan will be liquidated. Consider the following example:
+ - Borrower A creates a borrow offer with a duration of 10 days
+ - Lenders B, and C create lending offers with a max duration of 15 days
+ - When the orders are matched the initial loan duration is set to 10 days, now the maximum duration the borrower can extend to is 15 days. However if he calls the [extendLoan()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L547-L664) function, he will have to pay for 20 days. Essentially overpaying for 5 days, which he can't utilize. Depending on the amounts of the loan this may result in significant loses for the borrower.
+
+There are also parameters controlled by the admins of the protocol that can amplify the losses. For example the ``feePerDay`` is initially set to 4, the ``maxFEE`` is initially set to 80, so by dividing 80/4 we see that of now the borrower can be taxed for a 20 day loan at max. However those values can be changed by the admins of the protocol. For example the ``maxFEE`` can be set from 50 to 100 in the [DebitaV3Aggregator::setNewMaxFee()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L664-L668) function. The ``feePerDay`` can be set from 1 to 10 in the [setNewFee()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L658-L662) function. Essentially a borrower may have to overpay for up to ~90 days of fees, without having the chance to use the extended time properly. If we go back to the example above, if the loan is extended and the borrower pays for 10 additions days, after 15 days have passed the lenders can liquidate the loan by claiming the collateral.
+
+
+### Root Cause
+
+In the [extendLoan()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L547-L664) function, the fee that has to be paid by the borrower to the Debita team is calculated based on the sum of the block.timestamp of the loan creation, and the maxDuration specified by the lender, instead of just the maxDuration.

Keep in mind that loans in the Debita protocol are liquidated only when a certain amount of time has passed. As mentioned in the summary section, the amount, duration and certain parameters of the protocol may amplify the loses suffered by the borrower.

As can be seen from the above code snippet if the lend order is not perpetual the accrued interest will be added to the ``interestToClaim`` field.

+ }
+```
+As can be seen from the above code snippet if the lend order is perpetual the intrest generated after the loan has been extended will be directly send to the lend offer contract alongside with the principal of the loan, and the ``debtClaimed`` will be set to true. This prohibits the user from calling the [claimDebt()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L271-L286) function later on in order to receive the interest he accrued before the loan was extended. This results in the lender loosing the interest he has generated before the loan was extended, which based on the amount of the loan, the duration and the APR may be a significant amount. Keep in mind that most users of the protocol are not experienced web3 developers or auditors and most probably won't be tracking if and when a loan has been extended. They will expect that after certain time has passed, they will be able to claim their interest, or if they have set their lend order to be a perpetual one, they will expect just to sit back, and generate interest.
+
+### Root Cause
+
+The [payDebt()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L186-L257) function sets the ``debtClaimed`` to true, if a lend order is perpetual. The lender can't call the [claimDebt()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L271-L286) function in order to get his accrued interest, if he had any before the [payDebt()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L186-L257) function was called by the borrower to repay his debt.
+
+### Internal pre-conditions
+
+1. Borrow and Lend Orders are matched, the Lend orders are not perpetual
+2. Several days after the loan has been created pass, the borrower decides to extend the loan
+3. Some of the lenders decide to make their lend orders perpetual, without first claiming the interest they have generated before the loan was extended.

+# Borrower Can Reduce the Interest Owed to Each Accepted Lender
+
+### Summary
+
+Every time a borrower extends their loan, at the time of repayment, the lenders will lose the interest that was accrued before the loan extension.
+
+When `extendLoan()` is called, the interest accrued up until that point will be paid by the borrower. This interest will be added to `loanData._acceptedOffers[index].interestToClaim` for each lender linked to the loan, and it will be marked as already paid in `loanData._acceptedOffers[i].interestPaid`:
+```solidity
+ function extendLoan() public {
+
+ // Function code ...
+
+ for (uint i; i < m_loan._acceptedOffers.length; i++) {
+
+ // Function code ...
+
+ if (lendInfo.perpetual && lendInfo.owner == currentOwnerOfOffer) {
+ IERC20(offer.principle).approve(
+ address(lendOffer),
+ interestOfUsedTime - interestToPayToDebita
+ );
+ lendOffer.addFunds(
+ interestOfUsedTime - interestToPayToDebita
+ );
+ } else {
+>> loanData._acceptedOffers[i].interestToClaim += interestOfUsedTime - interestToPayToDebita;
+ }
+>> loanData._acceptedOffers[i].interestPaid += interestOfUsedTime;
+ }
+
+ // Function code ...
+ }
+```
+When `calculateInterestToPay()` is called, it computes the total interest accrued from the beginning of the loan until that moment and then subtracts the interest already paid (if any):
+```solidity
+function calculateInterestToPay(uint index) public view returns (uint) {
+ infoOfOffers memory offer = loanData._acceptedOffers[index];
+ uint anualInterest = (offer.principleAmount * offer.apr) / 10000;
+ // check already duration
+ uint activeTime = block.timestamp - loanData.startedAt;
+ uint minimalDurationPayment = (loanData.initialDuration * 1000) / 10000;
+ uint maxDuration = offer.maxDeadline - loanData.startedAt;
+ if (activeTime > maxDuration) {
+ activeTime = maxDuration;
+ } else if (activeTime < minimalDurationPayment) {
+ activeTime = minimalDurationPayment;
+ }
+
+ uint interest = (anualInterest * activeTime) / 31536000;
+
+ // subtract already paid interest
+>> return interest - offer.interestPaid;
+ }
+```
+The issue arises after extending a loan: when some interest has been paid, and the borrower repays the debt, the `calculateInterestToPay()` function will calculate the remaining interest to be paid. However, in `repayDebt()`, if the lender's offer is not perpetual, the interest to be paid will be **SET** to `loanData._acceptedOffers[index].interestToClaim`, instead of being added:
+
+```solidity
+function payDebt(uint[] memory indexes) public nonReentrant {
+
+ // Function code ...
+
+ for (uint i; i < indexes.length; i++) {
+
+ // Function code ...
+
+>> uint interest = calculateInterestToPay(index);
+ uint feeOnInterest = (interest * feeLender) / 10000;
+
+ // Function code ..
+
+ if (lendInfo.perpetual && lendInfo.owner == currentOwnerOfOffer) {
+ loanData._acceptedOffers[index].debtClaimed = true;
+ IERC20(offer.principle).approve(address(lendOffer), total);
+ lendOffer.addFunds(total);
+ } else {
+>> loanData._acceptedOffers[index].interestToClaim = interest - feeOnInterest;
+ }
+
+ // Function code ...
+ }
+
+}
+```
+So, the `interestToClaim` for each lender only reflects the interest accrued after the loan was extended, and any interest accrued before the extension will be lost.
+
+### Root Cause
+
+In [DebitaV3Loan:238](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L238) instead of add the interest accrued, is set.

+# M-1: Due to the incorrect implementation of the `changeOwner` function, the owner cannot be successfully changed.
+
+### Summary
+
+The contract's owner can only be changed within 0 to 6 hours after deployment, but in reality, the owner cannot be successfully changed. This is because the `changeOwner` function is incorrectly implemented, preventing the owner from being successfully changed.
+
+### Root Cause
+
+The incorrect implementation of the `changeOwner` function prevents the owner from being successfully changed.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+The current owner, for certain reasons, wants to change to a new owner within 6 hours. However, due to the incorrect implementation of the `changeOwner` function, the owner cannot actually be changed, so the owner will remain as the current owner's address.
+
+The following three `changeOwner` functions all have implementation errors.
+
+1. [DebitaV3Aggregator::changeOwner](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682-L686)
+2. [AuctionFactory::changeOwner](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L218-L222)
+3. [buyOrderFactory::changeOwner](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L186-L190)
+
+### Impact
+
+Due to the incorrect implementation of the `changeOwner` function, the owner cannot be successfully changed, which undermines the intended behavior of this feature.
+
+Personal opinion:
+1. The contest details do not specify that the owner is restricted or trusted.
+2. The requirement to change the owner within a limited time, such as within 6 hours, highlights the importance of this function!
+3. Although no financial loss has occurred, since `changeOwner` is a core function, I believe it meets the criteria for Medium severity according to Sherlock's evaluation, as a core function is affected.
+
+### PoC
+
+A simple POC demonstrating its impact: executing the `changeOwner` function in Remix.
+
+When the current owner attempts to change the address `0xAb8483F64d9C6d1EcF9b849Ae677dD3315835cb2` to a new owner, it is found that the owner is not successfully changed. The current owner remains `0x5B38Da6a701c568545dCfcB03FcB875f56beddC4`.
+
+```solidity
+// SPDX-License-Identifier: MIT
+pragma solidity ^0.8.26;
+
+// Owner: 0x5B38Da6a701c568545dCfcB03FcB875f56beddC4
+// changeOwner: 0xAb8483F64d9C6d1EcF9b849Ae677dD3315835cb2

+
+ constructor() {
+ owner = msg.sender;
+ }
+ function changeOwner(address owner) public returns (address){
+ require(msg.sender == owner, "Only owner");
+ return owner = owner;
+ }
+}
+```
+
+### Mitigation
+
+The following three functions can all be fixed in this way.
+
+1. `DebitaV3Aggregator::changeOwner`
+2. `AuctionFactory::changeOwner`
+3. `buyOrderFactory::changeOwner`
+
+```diff
+- function changeOwner(address owner) public {
++ function changeOwner(address newOwner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");

++ owner = newOwner;
+ }

+# The borrower pays duplicate interest for overlapping periods.
+
+### Summary
+
+The borrower pays duplicate interest for overlapping periods.
+
+### Root Cause
+
+When the borrower calls **DebitaV3Loan.extendLoan**, interest is settled once, with the time period being **`block.timestamp - loanData.startedAt;`**. However, when the borrower repays the loan by calling **payDebt**, interest is calculated again, using **`block.timestamp - loanData.startedAt;`**. Since **loanData.startedAt** is not updated within the **DebitaV3Loan.extendLoan** function, the borrower ends up paying duplicate interest for the same period, resulting in a loss of the borrower's assets. Additionally, the code section in the **extendLoan()** function [this part of the code](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L588-L592C37) does not serve any purpose.

+# M-2: `AuctionFactory::_deleteAuctionOrder` has an incorrect access control implementation, which could allow any user to delete an auction.
+
+### Summary
+
+The purpose of the `AuctionFactory::_deleteAuctionOrder` function is to delete a specific auction contract. However, due to an incorrect access control implementation, a malicious auction contract owner could delete other users' auction contracts.
+
+### Root Cause
+
+Due to the lack of validation for the `_AuctionOrder` parameter in the [AuctionFactory::_deleteAuctionOrder](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L145-L160) function, a malicious user can create an auction and then delete the auctions of other users.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. In `Auction.sol`, the auction owner can use `cancelAuction` to cancel/delete their own auction record and return the NFT to the seller, preventing the NFT from being stuck in the contract.
+2. However, due to incorrect access control in `AuctionFactory::_deleteAuctionOrder`,
+3. This allows malicious users to bypass the `cancelAuction` function, create an auction, and then use the `_deleteAuctionOrder` function to prematurely delete other users' auction records.
+
+### Impact
+
+A malicious user can create an auction and then delete the auction records of all other users.
+
+### PoC
+
+Attack scenario:
+
+User A: Creates auction contract A
+User B: Creates auction contract B
+
+At this point, auction contract B can:
+1. Call `_deleteAuctionOrder(address(A))`
+2. Since B is also an auction contract, it can pass the `onlyAuctions` check
+3. This allows it to delete the auction-related indexes and records of contract A!
+
+### Mitigation
+
+Fix suggestion: Require that `msg.sender == _AuctionOrder` in order to call this function.
+
+
+```diff
+- function _deleteAuctionOrder(address _AuctionOrder) external onlyAuctions {
++ require(msg.sender == _AuctionOrder,"Can only delete own auction");
+ // get index of the Auction order
+ uint index = AuctionOrderIndex[_AuctionOrder];
+ AuctionOrderIndex[_AuctionOrder] = 0;
+
+ // get last Auction order
+ allActiveAuctionOrders[index] = allActiveAuctionOrders[
+ activeOrdersCount - 1
+ ];
+ // take out last Auction order
+ allActiveAuctionOrders[activeOrdersCount - 1] = address(0);
+
+ // switch index of the last Auction order to the deleted Auction order
+ AuctionOrderIndex[allActiveAuctionOrders[index]] = index;
+ activeOrdersCount--;
+ }

+# `tokenURI()` creates metadata with wrong `_type`
+
+### Summary
+
+In the `tokenURI` function `_type` string can make the NFT associated either with `"Borrower"` or `"Lender"`. It assumes that every even number for `tokenId` must be a `"Borrower"` type, while odd number a `"Lender"`. This is not the case when `matchOffersV3()` is called with more than one lend order and multiple lender ownership NFTs are minted in a row.
+
+
+### Root Cause
+
+In `tokenURI` it is assumed that `"Borrower"` and `"Lender"` type tokens are sequentially one after another:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLoanOwnerships.sol#L84

+# Nobody can buy the `TaxTokenReceipt` NFT from auction
+
+### Summary
+
+Nobody can buy the `TaxTokenReceipt` NFT from auction due to the overrided `transferFrom` function. The `transferFrom` function is overrided with the following checks:
+```javascript
+function transferFrom(
+ address from,
+ address to,
+ uint256 tokenId
+ ) public virtual override(ERC721, IERC721) {
+ bool isReceiverAddressDebita = IBorrowOrderFactory(borrowOrderFactory)
+ .isBorrowOrderLegit(to) ||
+ ILendOrderFactory(lendOrderFactory).isLendOrderLegit(to) ||
+ IAggregator(Aggregator).isSenderALoan(to);
+ bool isSenderAddressDebita = IBorrowOrderFactory(borrowOrderFactory)
+ .isBorrowOrderLegit(from) ||
+ ILendOrderFactory(lendOrderFactory).isLendOrderLegit(from) ||
+ IAggregator(Aggregator).isSenderALoan(from);
+ // Debita not involved --> revert
+ require(
+ isReceiverAddressDebita || isSenderAddressDebita,
+ "TaxTokensReceipts: Debita not involved"
+ );
+```
+This ensures that the transfer of the NFT, will go smoothly through the system, but one thing is missing. The thing is that if a borrower doesn't pay off his debt amount and the loan is auctioned, nobody will be able to buy the NFT off. This is because the `transferFrom` function requires for the `from` and `to` addresses to be either a `BorrowOrder`, `LendOrder` or a `Loan` to be able to transfer the receipt NFT. At the point when the NFT is in the `Auction` contract it will be too late because neither the `Auction` contract nor the `msg.sender` is or can be one of the listed. This means that it is impossible to get any amount of collateral token out of the NFT, which means that the lenders will experience a big loss of funds
+
+### Root Cause
+
+The modifications of the `ERC721::transferFrom` function
+
+### Internal pre-conditions
+
+TaxTokenReceipt being used as loan collateral
+
+### External pre-conditions
+
+None
+
+### Attack Path
+
+1. User makes `BorrowOrder` with `TaxTokenReceipt` NFT as collateral
+2. The offer is matched and a loan is now created.
+3. Borrower doesn't pay his loan off
+4. Loan is auctioned and the NFT is transferred to the created auction (Up to this moment everything is going smoothly because at least one address in the sequence meets the criteria of being either a `BorrowOrder`, `LoanOrder` or a `Loan`)
+5. At this point there is no eligible address since the `Auction` address doesn't meet the criteria and the `msg.sender` is just unable to meet it since neither the `BorrowOrder` nor the `LendOrder` can call [`Auction::buyNFT`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109-L161) function.
+
+### Impact
+
+Lenders will experience big loss of funds, since the NFT can't be sold. Borrower will go off with their principle token and money that they should get in the form of NFT underlying are frozen forever.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Add a check to the `TaxTokenReceipt` NFT that ensures that an auction is active (Has an index different than 0 in the `auctionFactoryDebita::AuctionOrderIndex` mapping) and it is part of the `Debita` system (as it is indeed part of the system)

+# Pyth Oracle Confidence Interval Not Considered in Price Calculations
+
+### Summary
+
+The `DebitaPyth::getThePrice` function fetches asset prices using the Pyth oracle but does not account for the confidence interval published alongside the price. [According to Pyth’s documentation](https://docs.pyth.network/price-feeds/best-practices), the confidence interval provides a measure of uncertainty, representing a range within which the true price lies with 95% probability (e.g., $50,000 ± $10). Ignoring this interval can lead to inaccurate or unsafe valuations, especially during periods of market volatility or disagreement among publishers. Proper use of the confidence interval is essential for the protocol to mitigate risks and ensure accurate valuations.
+
+### Root Cause
+
+The [`getThePrice`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L25) function retrieves only the price field from the Pyth feed (priceData.price) without considering the confidence field, which provides a measure of uncertainty or variance in the reported price.

+### Internal pre-conditions

+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+During a volatile market, a malicious actor can exploit the lack of consideration for the confidence interval by manipulating the protocol's valuations.
+
+### Impact
+
+1. For collateral-based operations, the protocol may overvalue or undervalue collateral due to the uncertainty in the price.
+2. For loan operations, borrowers or lenders might gain an unfair advantage based on the protocol's inability to adjust for price uncertainty.
+Both cases result in a potential loss if fund

+# Vulnerability in `DLOFactory::deleteOrder()` allows owner of `DLOImplementation` to decrease `activeOrdersCount` as much they want.
+
+### Summary
+
+Missing proper checks in the `DLOFactory::deleteOrder()` function allow the owner of `DLOImplementation` to manipulate `activeOrdersCount`. This could lead to overwriting new `DLOImplementation` contracts deployed over previously deployed ones by tampering with `activeOrdersCount`. Additionally, it enables nullifying the `DLOImplementation` at index `activeOrdersCount = 0` .
+
+### Root Cause
+
+Missing proper checks for the Deleted order in the function `DLOFactory::deleteOrder()`
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207-L220
+
+### Internal pre-conditions
+
+NA
+
+### External pre-conditions
+
+NA
+
+### Attack Path
+
+1. The owner of the `DLOImplementation` contract calls the `DLOImplementation::cancelOffer()` function, which internally calls the `DLOFactory::deleteOrder()` function, resulting in the order being deleted from the `DLOFactory`.
+
+2. The owner then calls the `DLOImplementation::addFunds()` function, successfully depositing funds without any issue, enabling them to call the `DLOImplementation::cancelOffer()` function again.
+
+3. The owner calls `DLOImplementation::cancelOffer()`, triggering the `DLOFactory::deleteOrder()` function. This causes the deletion of the order at index 0 and decrements `activeOrdersCount` . This repetitive process can disrupt the protocol's core functionality by improperly manipulating the `activeOrdersCount` and impacting order management integrity.
+
+### Impact
+
+The vulnerability allows malicious manipulation of `activeOrdersCount`, disrupting order tracking, enabling overwriting of contracts, and compromising the protocol's core functionality.

+# An attacker can manipulate `TarotPriceOracle` prices, causing significant financial losses to protocol users.
+
+**Title**
+
+An attacker can manipulate `TarotPriceOracle` prices, causing significant financial losses to protocol users.
+
+---
+
+**Summary**
+
+The reliance on a short Time-Weighted Average Price (TWAP) window and lack of safeguards against flash loan attacks in the `TarotPriceOracle` contract will cause significant price manipulation for protocol users, as an attacker can manipulate the Uniswap V2 pair reserves within the TWAP window or via flash loans to alter the oracle price, leading to financial losses.
+
+---
+
+**Root Cause**
+
+In `[TarotPriceOracle.sol:10](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/MixOracle/TarotOracle/TarotPriceOracle.sol#L10)`, the TWAP window (`MIN_T`) is set to 1200 seconds (20 minutes), which is too short to prevent price manipulation:
+
+```solidity
+uint32 public constant MIN_T = 1200; // Line 11
+
+```
+
+Additionally, in the `getPriceCumulativeCurrent` function, the oracle relies directly on Uniswap V2 spot prices without any checks to prevent flash loan manipulation or cross-validation with other price sources.
+
+---
+
+**Internal Pre-conditions**
+
+1. The `MIN_T` constant in the `TarotPriceOracle` contract is set to `1200` seconds.
+2. The oracle does not implement checks for large price deviations or circuit breakers.
+3. The oracle calculates prices based directly on Uniswap V2 pair reserves without additional safeguards.
+
+---
+
+**External Pre-conditions**
+
+1. An attacker can manipulate Uniswap V2 pair reserves, either through regular trades or flash loans.
+
+---
+
+**Attack Path**
+
+1. **TWAP Manipulation Attack:**
+ - The attacker performs trades to manipulate the Uniswap V2 pair reserves, causing a significant price change within the short TWAP window.
+ - The attacker waits for the minimum time window `MIN_T` to pass.
+ - The `TarotPriceOracle` updates the price based on the manipulated reserves.
+ - The attacker exploits the manipulated price, causing losses to protocol users relying on the oracle.
+2. **Flash Loan Attack:**
+ - The attacker takes out a flash loan to manipulate the Uniswap V2 pair reserves significantly within a single transaction.
+ - The `TarotPriceOracle` reads the manipulated reserves to calculate the price.
+ - The attacker exploits the manipulated price before the reserves return to normal, causing losses to protocol users.
+
+---
+
+**Impact**
+
+Protocol users suffer significant financial losses due to manipulated prices, leading to:
+
+- Unfair liquidations.
+- Inflated borrowing capacity.
+- Potential protocol insolvency.
+
+In the proof of concept, up to a **249% price manipulation** was demonstrated through TWAP window exploitation and **200% manipulation** via flash loan attacks.

+
+```
+---
+
+**Mitigation**
+---
+
+**Mitigation**
+
+1. **Increase the TWAP Window Duration:**
+
+ Extend the TWAP window to reduce susceptibility to short-term price manipulations.
+
+ ```solidity
+ uint32 public constant MIN_T = 3600; // Increase to 1 hour minimum
+
+ ```
+
+2. **Implement Price Deviation Limits:**
+
+ Add checks to prevent large, sudden changes in price from being accepted by the oracle.
+
+ ```solidity
+ uint256 constant MAX_PRICE_DEVIATION = 10; // 10% maximum deviation
+
+ function checkPriceDeviation(uint256 newPrice, uint256 oldPrice) internal {
+ require(
+ (newPrice <= oldPrice * (100 + MAX_PRICE_DEVIATION) / 100) &&
+ (newPrice >= oldPrice * (100 - MAX_PRICE_DEVIATION) / 100),
+ "Price deviation too high"
+ );
+ }
+
+ ```
+
+3. **Implement Circuit Breakers:**
+
+ Introduce mechanisms to halt operations when abnormal price movements are detected.
+
+4. **Cross-Validate Prices with Multiple Oracles:**
+
+ Use multiple price sources, such as integrating Chainlink as the primary oracle, to validate price data and reduce reliance on a single source.
+
+5. **Upgrade to Uniswap V3's TWAP Mechanism:**
+
+ Utilize Uniswap V3's more robust TWAP calculations that are less susceptible to manipulation.
+
+
+---
+
+**Conclusion**
+
+The identified vulnerabilities are confirmed through code analysis and practical testing. Immediate action is required to mitigate the risks and protect protocol users from potential financial losses.

+# Stale and Uncertain Price Data in `DebitaPyth` Oracle Can Lead to Incorrect Valuations and Financial Risks
+
+### **Title**
+
+Stale and Uncertain Price Data in `DebitaPyth` Oracle Can Lead to Incorrect Valuations and Financial Risks
+
+---
+
+### **Summary**
+
+The `DebitaPyth` smart contract is vulnerable due to a lenient staleness window, absence of confidence interval checks, and reliance on a single oracle source. These issues can cause the contract to accept stale or highly uncertain price data, leading to incorrect asset valuations. As a result, protocol users may face inaccurate trading decisions, unfair liquidations, and increased operational risks, undermining the financial integrity of the protocol.
+
+---
+
+### **Root Cause**
+
+1. **Lenient Staleness Window:**
+ - **Location:** [`contracts/oracles/DebitaPyth.sol:32`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L32-L35)
+ - **Details:** The staleness threshold is set to 600 seconds (10 minutes), which is insufficient for volatile assets, allowing outdated price data to be accepted.
+ - **Code Snippet:**
+
+ ```solidity
+ // 10-minute staleness window
+ PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ _priceFeed,
+ 600 // seconds
+ );
+
+ ```
+
+2. **Lack of Confidence Interval Checks:**
+ - **Location:** `contracts/oracles/DebitaPyth.sol:32` (and related logic)
+ - **Details:** The contract does not verify the confidence interval (`conf`) of the retrieved price data, risking the acceptance of imprecise or highly uncertain prices.
+3. **Single Oracle Dependency:**
+ - **Design Choice:** The contract relies solely on the Pyth oracle for price data, introducing a single point of failure and increasing the risk of operational disruptions.
+
+---
+
+### **Internal Pre-conditions**
+
+1. The staleness threshold in the `DebitaPyth` contract is set to `600` seconds.
+2. The contract does not implement checks for the confidence interval of price data.
+3. The `DebitaPyth` contract depends exclusively on the Pyth oracle for price retrieval without integrating additional oracle sources.
+
+---
+
+### **External Pre-conditions**
+
+1. An attacker can manipulate the Pyth oracle to provide stale or highly uncertain price data.
+2. The Pyth oracle service experiences downtime or delays, causing the `DebitaPyth` contract to rely on outdated price information.
+3. Volatile market conditions lead to rapid price fluctuations, making a 10-minute staleness window insufficient to capture accurate price movements.
+
+---
+
+### **Attack Path**
+
+1. **Stale Price Exploitation:**
+ - The attacker manipulates the Pyth oracle to provide price data that is 10 minutes old or older.
+ - The `DebitaPyth` contract retrieves and accepts this stale price data.
+ - Protocol users rely on the outdated price for trading decisions or collateral assessments, leading to incorrect valuations.
+2. **High Confidence Interval Exploitation:**
+ - The attacker forces the Pyth oracle to provide price data with a high confidence interval (`conf`), indicating low confidence in the price accuracy.
+ - The `DebitaPyth` contract accepts this imprecise price data without verification.
+ - Protocol operations based on this uncertain price data result in financial inaccuracies and potential losses.
+3. **Single Oracle Failure:**
+ - The Pyth oracle becomes unavailable or provides faulty data.
+ - Since `DebitaPyth` relies solely on Pyth, it cannot retrieve accurate price data.
+ - The protocol halts operations or continues with incorrect data, leading to operational disruptions and financial risks.
+
+---
+
+### **Impact**
+
+Protocol users are exposed to significant financial and operational risks, including:
+
+- **Use of Stale Prices:** Outdated price data can lead to incorrect asset valuations, affecting trading decisions and collateral assessments.
+- **High Price Uncertainty:** Acceptance of prices with high confidence intervals increases the risk of financial losses due to imprecise valuations.
+- **Operational Risk:** Dependency on a single oracle source can disrupt protocol operations in the event of oracle downtime or manipulation, potentially leading to protocol insolvency or loss of user funds.
+
+**Proof of Vulnerability:**
+
+- **Stale Price Acceptance:** Demonstrated that the contract accepts price data up to **10 minutes** old, which can be exploited for inaccurate valuations.
+- **High Confidence Interval Acceptance:** Showed that the contract accepts price data with high uncertainty, allowing significant price manipulation.
+- **Single Oracle Dependency:** Highlighted the risk of operational disruptions due to reliance on a single oracle source.

+
+### **Mitigation**
+
+To address the identified vulnerabilities in the `DebitaPyth` contract, the following mitigations are recommended:
+
+1. **Configure Asset-Specific Staleness Thresholds:**
+
+ Allow customization of staleness windows based on the volatility of each asset. This ensures that highly volatile assets have shorter staleness thresholds to capture rapid price movements accurately.
+
+ ```solidity
+ mapping(address => uint) public maxStaleness;
+
+ function setMaxStaleness(address token, uint staleness) external onlyOwner {
+ maxStaleness[token] = staleness;
+ }
+
+ function getThePrice(address token) public view returns (int) {
+ require(maxStaleness[token] > 0, "Staleness not configured");
+
+ PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ priceIdPerToken[token],
+ maxStaleness[token]
+ );
+ // ... existing logic
+ }
+
+ ```
+
+2. **Implement Confidence Interval Checks:**
+
+ Verify that the confidence interval (`conf`) of the retrieved price data is within acceptable limits to ensure price accuracy.
+
+ ```solidity
+ uint256 public constant MAX_CONFIDENCE = 1e16; // Adjust based on acceptable risk
+
+ function getThePrice(address token) public view returns (int) {
+ require(maxStaleness[token] > 0, "Staleness not configured");
+
+ PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ priceIdPerToken[token],
+ maxStaleness[token]
+ );
+
+ require(priceData.conf <= MAX_CONFIDENCE, "Price uncertainty too high");
+
+ // ... existing logic
+ }
+
+ ```
+
+3. **Introduce Redundant Oracles:**
+
+ Incorporate multiple oracle sources to eliminate single points of failure and enhance the reliability of price data.
+
+ ```solidity
+ interface IOracle {
+ function getPrice(address token) external view returns (int, uint);
+ }
+
+ IOracle[] public oracles;
+
+ function addOracle(IOracle oracle) external onlyOwner {
+ oracles.push(oracle);
+ }
+
+ function getThePrice(address token) public view returns (int) {
+ int aggregatedPrice;
+ uint totalConfidence;
+
+ for (uint i = 0; i < oracles.length; i++) {
+ (int price, uint conf) = oracles[i].getPrice(token);
+ aggregatedPrice += price;
+ totalConfidence += conf;
+ }
+
+ require(oracles.length > 0, "No oracles available");
+ return aggregatedPrice / int(oracles.length);
+ }
+
+ ```
+
+4. **Monitor Oracle Health:**
+
+ Implement monitoring mechanisms to detect and respond to oracle outages or anomalies promptly, ensuring the protocol can take corrective actions such as pausing operations or switching to backup oracles.
+
+ ```solidity
+ event OraclePaused(address oracle);
+ event OracleResumed(address oracle);
+
+ mapping(address => bool) public oraclePaused;
+
+ function pauseOracle(address oracle) external onlyManager {
+ oraclePaused[oracle] = true;
+ emit OraclePaused(oracle);
+ }
+
+ function resumeOracle(address oracle) external onlyManager {
+ oraclePaused[oracle] = false;
+ emit OracleResumed(oracle);
+ }
+
+ function getThePrice(address token) public view returns (int) {
+ require(maxStaleness[token] > 0, "Staleness not configured");
+
+ // Check if all oracles are active
+ for (uint i = 0; i < oracles.length; i++) {
+ require(!oraclePaused[address(oracles[i])], "Oracle is paused");
+ }
+
+ // ... existing logic
+ }
+
+ ```
+
+5. **Implement Fallback Mechanisms:**
+
+ Utilize fallback or alternative price retrieval methods in case primary oracles fail, ensuring continuous and accurate price data availability.
+
+ ```solidity
+ function getThePrice(address token) public view returns (int) {
+ require(maxStaleness[token] > 0, "Staleness not configured");
+
+ // Try primary oracle
+ try pyth.getPriceNoOlderThan(priceIdPerToken[token], maxStaleness[token]) returns (PythStructs.Price memory priceData) {
+ require(priceData.conf <= MAX_CONFIDENCE, "Price uncertainty too high");
+ return priceData.price;
+ } catch {
+ // Fallback to secondary oracle
+ require(oracles.length > 0, "No fallback oracle available");
+ (int price, uint conf) = oracles[0].getPrice(token);
+ require(conf <= MAX_CONFIDENCE, "Fallback price uncertainty too high");
+ return price;
+ }
+ }
+
+ ```
+
+
+---
+
+### **Conclusion**
+
+The `DebitaPyth` contract exhibits critical vulnerabilities related to the acceptance of stale and highly uncertain price data, compounded by reliance on a single oracle source. These issues can be exploited to manipulate asset valuations, leading to significant financial and operational risks for protocol users. Immediate implementation of the recommended mitigations—such as configuring asset-specific staleness thresholds, enforcing confidence interval checks, introducing redundant oracles, and monitoring oracle health—is essential to safeguard the protocol's integrity and protect its users from potential financial losses.

+# Malicious actors will manipulate TWAP prices through timestamp overflow in TarotOracle affecting all Debita V3 users
+
+# Malicious actors will manipulate TWAP prices through timestamp overflow in TarotOracle affecting all Debita V3 users
+
+## Summary
+A critical vulnerability in TarotOracle's timestamp handling mechanism will cause significant price manipulation risks for Debita V3 users as malicious actors can exploit timestamp overflow to manipulate TWAP calculations, potentially leading to incorrect asset valuations and protocol losses.
+
+## Root Cause
+In [TarotPriceOracle.sol:143](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/MixOracle/TarotOracle/TarotPriceOracle.sol#L127-L130) the `getBlockTimestamp()` function uses a 32-bit integer modulo operation which causes timestamp overflow:
+
+```solidity
+function getBlockTimestamp() public view returns (uint32) {
+ return uint32(block.timestamp % 2 ** 32);
+}
+```
+
+This overflow affects the time difference calculation used in TWAP price determination:
+
+```solidity
+T = blockTimestamp - lastUpdateTimestamp; // overflow is desired
+require(T >= MIN_T, "TarotPriceOracle: NOT_READY");
+price = toUint224((priceCumulativeCurrent - priceCumulativeLast) / T);
+```
+
+## Internal pre-conditions
+1. TarotOracle needs to be initialized and actively providing price feeds
+2. The block.timestamp needs to be approaching the 2^32 wrap point
+3. The oracle update must occur within the MIN_T window (1200 seconds)
+4. Price cumulative values must be properly tracking Uniswap pair reserves
+
+## External pre-conditions
+1. Sufficient liquidity in the Uniswap pair being used as the price source
+2. Block timestamps must be manipulatable by miners/validators within normal variance
+3. No external circuit breakers or price deviation checks in place
+
+## Attack Path
+1. Attacker monitors the TarotOracle for timestamp approaching 2^32 seconds
+2. Attacker prepares a large liquidity position in the target Uniswap pair
+3. Just before the timestamp wrap point:
+ - Attacker manipulates the underlying pool price
+ - Waits for the timestamp to wrap around
+4. When timestamp wraps:
+ - Oracle calculates incorrect time difference due to overflow
+ - TWAP calculation uses wrong time period
+ - Results in manipulated price feed
+5. Attacker exploits the incorrect price by:
+ - Borrowing against collateral at manipulated valuations
+ - Executing trades at favorable prices
+ - Avoiding liquidations or forcing incorrect liquidations
+
+## Impact
+The protocol and its users suffer from multiple severe impacts:
+
+1. **Financial Impact:**
+ - Users can suffer up to 100% loss of collateral due to incorrect liquidations
+ - Protocol can suffer significant losses from mispriced assets
+ - Attackers can profit from price differences between true market value and manipulated oracle price
+
+2. **Technical Impact:**
+ - All systems relying on TarotOracle receive incorrect price data
+ - Cascading failures in connected protocols
+ - Loss of price feed reliability every 2^32 seconds (~136 years)

+## Mitigation
+Several layers of mitigation are recommended:

+ ```solidity
+ // Replace uint32 with uint256 for timestamp
+ function getBlockTimestamp() public view returns (uint256) {
+ return block.timestamp;
+ }
+
+ // Add sanity checks for time differences
+ function getResult(address uniswapV2Pair) external returns (uint224 price, uint256 T) {
+ // ... existing code ...
+ T = blockTimestamp - lastUpdateTimestamp;
+ require(T >= MIN_T && T <= MAX_T, "TarotOracle: INVALID_TIME_DIFFERENCE");
+ // ... rest of the code ...
+ }
+ ```
+
+2. **Additional Safeguards:**
+ - Implement price deviation bounds
+ - Add multiple oracle sources for price validation
+ - Implement circuit breakers for large price movements
+ - Add maximum time window restrictions
+
+3. **Long-term Solutions:**
+ - Consider migrating to Chainlink or other established oracle solutions
+ - Implement a more robust TWAP calculation mechanism
+ - Add governance controls for critical oracle parameters

+# Precision Loss in MixOracle Will Lead to Protocol Insolvency
+
+# Precision Loss in MixOracle Will Lead to Protocol Insolvency
+
+## Summary
+A critical precision loss in MixOracle's price calculation will cause significant financial losses for protocol users as malicious actors can manipulate Uniswap pool liquidity to force price calculation failures or extreme inaccuracies, leading to incorrect loan valuations and failed liquidations.
+
+## Root Cause
+In [`contracts/oracles/MixOracle/MixOracle.sol:60-66`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/MixOracle/MixOracle.sol#L60-L66) there are multiple critical issues:
+
+1. Division before multiplication in price calculations:
+```solidity
+int amountOfAttached = int(
+ (((2 ** 112)) * (10 ** decimalsToken1)) / twapPrice112x112
+);
+
+uint price = (uint(amountOfAttached) * uint(attachedTokenPrice)) /
+ (10 ** decimalsToken1);
+```
+
+2. Missing zero-value checks on critical price inputs
+3. Unsafe type conversions between uint224, int, and uint
+4. Unused decimalsToken0 variable indicating incomplete decimal handling
+
+## Internal pre-conditions
+1. MixOracle needs to be integrated with a Uniswap V2 pair
+2. TarotOracle needs to be initialized for the pair
+3. Pyth oracle price feed needs to be active
+4. Protocol needs to use MixOracle for loan valuations or liquidations
+
+## External pre-conditions
+1. Uniswap V2 pair needs to have manipulatable liquidity
+2. Flash loan source needs to be available for large-scale manipulation
+3. Gas price needs to be reasonable for multiple transactions
+
+## Attack Path
+1. Attacker identifies a target Uniswap V2 pair used by MixOracle
+2. Attacker takes out a flash loan to acquire large amounts of tokens
+3. Attacker manipulates the Uniswap pool to create extreme reserve ratios
+4. Protocol calls MixOracle.getThePrice() for loan valuation
+5. Price calculation fails or returns extremely inaccurate values due to precision loss
+6. Attacker exploits the incorrect pricing through one of these vectors:
+ - Takes out under-collateralized loans
+ - Prevents legitimate liquidations
+ - Forces incorrect liquidations
+7. Attacker profits from the price disparity and exits
+
+## Impact
+The protocol and its users suffer from multiple severe impacts:
+
+1. Financial Losses:
+ - Under-collateralized loans due to inflated asset prices
+ - Unfair liquidations due to deflated asset prices
+ - Failed liquidations due to zero price returns
+
+2. System Stability:
+ - Oracle becomes unreliable for all integrated protocols
+ - Liquidation mechanisms fail to maintain system solvency
+ - Cascading liquidations during market stress
+
+Estimated loss potential: Up to 100% of affected loan positions

+ }
+ }
+}
+```
+
+## Mitigation
+
+### Short-term Fixes
+
+1. Add input validation:
+```solidity
+function getThePrice(address tokenAddress) public returns (int) {
+ // ... existing code ...
+
+ require(twapPrice112x112 > 0, "Invalid TWAP price");
+ require(attachedTokenPrice > 0, "Invalid Pyth price");
+
+ // ... rest of the code ...
+}
+```
+
+2. Implement safe price calculation:
+```solidity
+function getThePrice(address tokenAddress) public returns (int) {
+ // ... existing code ...
+
+ // Safer calculation order
+ uint256 numerator = uint256(attachedTokenPrice) * (2 ** 112);
+ require(numerator <= type(uint256).max / (10 ** decimalsToken1), "Overflow check");
+ numerator = numerator * (10 ** decimalsToken1);
+
+ uint256 denominator = uint256(twapPrice112x112) * (10 ** decimalsToken1);
+ require(denominator > 0, "Invalid denominator");
+
+ uint256 price = numerator / denominator;
+ require(price > 0, "Invalid final price");
+
+ return int(price);
+}
+```
+
+### Long-term Recommendations
+
+1. Implement circuit breakers for extreme price movements
+2. Add multiple oracle sources for price validation
+3. Use a proper fixed-point math library
+4. Add price deviation checks between updates
+5. Implement TWAP manipulation protection
+6. Regular system stress testing with extreme scenarios

+# Malicious actors can manipulate token prices to zero in MixOracle leading to unfair liquidations
+
+# Malicious actors can manipulate token prices to zero in MixOracle leading to unfair liquidations
+
+## Summary
+Precision loss in MixOracle's price calculation will cause unfair liquidations and protocol insolvency as attackers can manipulate token prices to round down to zero, allowing them to liquidate positions at no cost and steal user collateral.
+
+## Root Cause
+In [MixOracle.sol:L60-L66](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/MixOracle/MixOracle.sol#L60-L66) the price calculation performs division before multiplication and lacks proper decimal scaling:
+
+```solidity
+int amountOfAttached = int(
+ (((2 ** 112)) * (10 ** decimalsToken1)) / twapPrice112x112
+);
+
+uint price = (uint(amountOfAttached) * uint(attachedTokenPrice)) /
+ (10 ** decimalsToken1);
+```
+
+The issue occurs because:
+1. Division by `twapPrice112x112` happens before scaling, causing precision loss
+2. No minimum price bounds are enforced
+3. Improper decimal handling between tokens with different decimal places
+
+## Internal pre-conditions
+1. Protocol needs to have a lending pool using MixOracle for price feeds
+2. A token pair needs to be set up in Uniswap V2 with the target token and USDC/USDT
+3. The target token needs to be approved as collateral in the lending protocol
+4. Users need to have open positions using the vulnerable token as collateral
+
+## External pre-conditions
+1. Uniswap V2 pair needs to have sufficient liquidity to allow price manipulation
+2. The token price needs to be manipulatable to a value less than 0.001 USD
+
+## Attack Path
+
+1. Attacker identifies a token with low price or creates a new token
+2. Attacker sets up a Uniswap V2 pair with USDC
+3. Attacker manipulates the TWAP price to be extremely high by:
+ ```solidity
+ // Example: Set reserves to make price very low
+ pair.setReserves(1000000 * 1e6, 1 * 1e18); // 1M USDC : 1 TOKEN
+ ```
+4. When MixOracle calculates the price:
+ ```solidity
+ // twapPrice112x112 becomes very large
+ // Division results in amountOfAttached = 0
+ int amountOfAttached = int(
+ (((2 ** 112)) * (10 ** decimalsToken1)) / twapPrice112x112
+ );
+ ```
+5. Final price calculation results in zero:
+ ```solidity
+ uint price = (0 * attachedTokenPrice) / (10 ** decimalsToken1) = 0
+ ```
+6. Attacker can now liquidate any position using this token as collateral at zero cost
+
+## Impact
+The protocol users suffer a 100% loss of their collateral. The attacker gains the entire collateral value at no cost. This vulnerability affects any token that can be manipulated to have a very low price, potentially impacting multiple lending pools and users.

+ // In real scenario, attacker would now call liquidate()
+ // with zero payment and receive all collateral
+ }
+}
+```
+
+## Mitigation
+
+1. Implement proper decimal scaling:
+```solidity
+contract MixOracle {
+ uint256 constant PRECISION = 1e18;
+ uint256 constant MIN_PRICE = 1e6; // $0.001 minimum price
+
+ function getThePrice(address tokenAddress) public returns (int) {
+ (uint224 twapPrice112x112, ) = priceFeed.getResult(uniswapPair);
+
+ // Convert to standard precision first
+ uint256 basePrice = (uint256(twapPrice112x112) * PRECISION) / 2**112;
+
+ // Scale for decimal differences
+ uint256 decimalAdjustment = 10**(PRECISION - decimalsToken1);
+ uint256 scaledPrice = (basePrice * decimalAdjustment);
+
+ // Apply attached token price
+ uint256 finalPrice = (scaledPrice * uint256(attachedTokenPrice)) / PRECISION;
+
+ // Enforce minimum price
+ require(finalPrice >= MIN_PRICE, "Price too low");
+
+ return int(finalPrice);
+ }
+}
+```
+
+2. Add multiple price sources:
+```solidity
+function validatePrice(uint256 price) internal {
+ uint256 chainlinkPrice = getChainlinkPrice();
+ require(
+ percentDifference(price, chainlinkPrice) <= MAX_DEVIATION,
+ "Price deviation too high"
+ );
+}
+```
+
+3. Implement circuit breakers for extreme price movements:
+```solidity
+uint256 public lastPrice;
+uint256 constant MAX_PRICE_CHANGE = 50; // 50%
+
+function validatePriceChange(uint256 newPrice) internal {
+ if (lastPrice > 0) {
+ uint256 change = percentDifference(newPrice, lastPrice);
+ require(change <= MAX_PRICE_CHANGE, "Price change too large");
+ }
+ lastPrice = newPrice;
+}
+```

+
+### Summary
+
+When a borrower calls `payDebt()`, if the `lendOffer` is a `perpetual` loan, the funds are returned to the `lendOffer` contract .

+# Malicious users will exploit the incentive mechanism rendering it useless
+
+### Summary
+
+Specific token pairs can be incentivized to encourage new loans. This approach aims to foster widespread engagement and utilization of the platform's financial offerings.
+
+However, this goal may not be achieved, as a malicious user could create their own compatible lending and borrowing orders just a few seconds before the incentivized epoch ends. This would allow them to manipulate the shares of all users and claim the majority for themselves. They would match their own orders and immediately repay the created loan.
+
+### Root Cause
+
+The owner of a borrowing and lending order can be the same address. Furthermore, [DebitaIncentives::updateFunds()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L631-L636) is called when borrowing and lending orders are matched, which means that a user could immediately repay loans consisting of their own orders after they are matched.
+The way incentives are designed allows users to exploit this.
+
+### Internal pre-conditions
+
+None.
+
+### External pre-conditions
+
+None.
+
+### Attack Path
+
+1. An incentivizer calls `DebitaIncentives::incentivizePair()` to incentivize a pair for a future epoch.
+2. During that epoch, multiple users' loans are matched, which updates the amount of funds that have been lent and borrowed during that period.
+3. A few seconds before the epoch ends, a malicious user creates their own compatible lending and borrowing orders with `apr = 0`, as they do not care about the interest since they plan to repay their debt after a few seconds, and `duration <= 1 day`.
+4. They match these orders by calling `DebitaV3Aggregator::matchOffersV3()`. They only need to pay a `0.2%` [fee](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L529-L531) since the initial loan duration is less than `1 day`. As long as the incentives they receive are worth more than `0.2%` of the principle amount they lend, this strategy remains profitable.
+5. After a few seconds, the malicious user calls `DebitaV3Loan::payDebt()` to repay their debt. This does not result in any loss for the user, as the apr is set to `0`, meaning the protocol does not charge any fees.
+6. Finally, the malicious user calls `DebitaIncentives::claimIncentives()` to claim their rewards.
+
+### Impact
+
+The goal of incentives—to foster widespread engagement and utilization of the platform's financial offerings—is not achieved, rendering them useless. Malicious users exploit the system to maximize their incentives by simply matching their own orders for a few seconds.
+
+Over time, more users become aware of this exploit and begin doing the same. As a result, users who use the protocol as intended are unable to claim their incentives and are effectively penalized by the actions of malicious users.
+
+The initial purpose of the incentives is undermined as users realize it is not worth interacting with incentivized pairs. They earn little to no rewards because malicious users drive their shares close to zero. Ultimately, incentives are merely rewarded to users who match their own orders for a brief moment, such as one second.
+Therefore, the funds of the incentivizers will be lost as they do not achieve their goal and are simply donations to malicious users.

+```
+
+### Mitigation
+
+Consider not allowing the owner of the lending and borrowing orders that are matched to be the same.
+Additionally, consider revising the method for calculating users' shares of incentives, as loans lasting only one second are currently treated the same as loans lasting several months.

+# Malicious user can create multiple lend orders with zero lending amounts, disrupting protocol efficiency
+
+### Summary
+
+The lack of validation for zero lending amounts in the `createLendOrder` function will disrupt the protocol's efficiency, as empty lend orders will be created. This will negatively impact the order-matching process, causing unnecessary computational overhead for the protocol. Additionally, the connector (whether a bot or another participant) may lose fees while attempting to match these empty lend orders.
+
+### Root Cause
+
+In [`DLOFactory::createLendOrder`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L124), the `_startedLendingAmount` parameter is not validated for a non-zero value before proceeding with the transaction. This allows empty lend orders to be created, which can bloat the system and degrade its performance when attempting to match orders.
+
+
+
+### Internal pre-conditions
+
+1. An attacker or user needs to call `createLendOrder()` with `_startedLendingAmount` set to 0.
+2. The lendOfferProxy contract will still be deployed despite the zero value, leading to an empty order.
+3. The protocol processes these transactions without reverting, storing the empty orders in its active list.
+
+### External pre-conditions
+
+1. The chain allows transactions with zero-value transfers (this is common for chains like Sonic, Base, Arbitrum, and OP).
+2. The gas price must be low enough for the attack to be feasible without excessive cost.
+
+### Attack Path
+
+1. The attacker calls `createLendOrder()` with `_startedLendingAmount` set to `0` multiple times.
+2. `SafeERC20.safeTransferFrom()` is invoked, but no funds are transferred due to the zero value.
+3. The empty lend order is created and stored in the system, consuming unnecessary resources.
+4. The connector (bot or user) attempts to match offers, wasting resources and possibly losing fees by matching empty lend orders.
+
+### Impact
+
+The protocol’s efficiency is disrupted as empty lend orders clog the order-matching process, leading to wasted gas fees. The connector, which is responsible for matching orders, will lose fees trying to match these empty offers, resulting in financial losses and operational inefficiencies. The attacker does not directly profit but burdens the protocol with inefficiencies.
+
+### PoC
+

+# Any authorized lend order can disrupt the protocol's matching process.
+
+### Summary
+
+The unrestricted use of the [`deleteOrder`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207) function in [ `DebitaV3LoanFactory.sol`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207), as it only checks if a lendOrder is legit through [`onlyLendOrder`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L102C14-L102C27) will cause disruption to the matching process for connectors (users or bots) retrieving active lend orders. As any lend order can call `deleteOrder` to remove entries from `allActiveLendOrders`, it disrupts the `getActiveOrders` function, which connectors will rely on to retrieve `DLOImplementation.LendInfo`, thereby disturbing the matchOffersV3 process.
+
+### Root Cause
+
+In [`DebitaV3LoanFactory.sol:207`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207), the `deleteOrder` function allows any lend order to remove itself or others from `allActiveLendOrders`, impacting the ability to retrieve active orders via [`getActiveOrders`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L222).
+
+### Internal pre-conditions
+
+1. A valid lend order must call deleteOrder.
+2. The lend order must exist in the allActiveLendOrders mapping.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. An authorized lend order calls `deleteOrder` with a valid `_lendOrder` address.
+2. The order is removed from `allActiveLendOrders`, breaking the indexing.
+3. A connector calling `getActiveOrders` encounters incomplete or incorrect data.
+4. This prevents proper matching via `DebitaV3Aggregator::matchOffersV3`, disrupting the protocol’s functionality.
+
+### Impact
+
+1. **Economic Disruption:** The matching process is disrupted, causing delays in transactions and potential loss of revenue for both lenders and borrowers.
+2. **Fee Monopolization:** A malicious user could repeatedly remove other lend orders, after retreiving `allActiveLendOrders`. This allows them to monopolize the 15% connector fee by becoming the only participant capable of matching offers, leading to an unfair advantage and a compromised system.
+
+### PoC
+
+Add this test to `/test/local/Loan/MultiplePrinciples.t.sol`.
+```solidity

+# No Check for Sequencer Uptime Can Lead to Dutch Auctions Executing at Unfavorable Prices.
+
+### Summary
+
+Debita will be deployed on Arbitrum, Optimism, and other Layer 2 solutions, making it susceptible to sequencer downtime.
+
+The `Auction` contract implements a Dutch auction mechanism with linear price decay, which can either recover debt from NFT collateral or allow users to sell NFTs via a Dutch auction. However, there is no check for sequencer uptime, which could result in auctions executing at unfavorable prices.
+
+If the sequencer goes offline during the auction, the price will continue to decrease, even though no transactions can be processed. Once the sequencer comes back online, users may be able to purchase tokens from these auctions at significantly lower prices than the market price.
+
+Auctions can be created by anyone using the `AuctionFactory::createAuction` function, with arbitrary values for `_initialAmount`, `_floorAmount`, and `_duration`. Alternatively, auctions can be used to liquidate loan collateral via `DebitaV3Loan::createAuctionForCollateral`. In this case, the parameters are set as follows:
+
+- `_initialAmount = lockedAmount`
+- `_floorAmount = 15% of _initialAmount`
+- `_duration = 864,000 seconds (10 days)`
+
+Network outages and large reorganizations occur with relative frequency. In 2022, the Arbitrum network suffered an outage of approximately [seven hours](https://cointelegraph.com/news/arbitrum-network-suffers-minor-outage-due-to-hardware-failure). A 78-minute outage also occurred in December 2023 [here](https://cointelegraph.com/news/arbitrum-network-goes-offline-december-15).
+
+### Root Cause
+
+In [Auction](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L31) and [AuctionFactory](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L10) no check for sequencer uptime.
+
+### Internal pre-conditions
+
+1. An auction is created either to liquidate a loan collateral or to simply sell an NFT via the Debita platform.
+
+### External pre-conditions
+
+1. Sequencer is down for a number of hours.
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+Any ongoing liquidations that are temporarily blocked by a sequencer outage will continue to experience price decay. When the sequencer goes back online, liquidation will have dropped significantly in price, causing liquidation to happen at an unfair price.
+
+### PoC
+
+
+To demonstrate the issue caused by the lack of a check for sequencer uptime, we’ll walk through a real-world scenario where the sequencer goes offline during a Dutch auction.
+
+#### Auction Parameters
+
+- **Initial Amount (`_initialAmount`)**: $1000 (representing Bob's debt).
+- **Floor Amount (`_floorAmount`)**: $150 (15% of the initial amount).
+- **Auction Duration (`_duration`)**: 864,000 seconds (10 days).
+- **Sequencer Downtime**: 1 hour (3,600 seconds).
+
+#### Scenario Breakdown
+
+1. **Auction Begins**:
+ - The auction starts with an initial price of $1000 for Bob’s collateral (NFT).
+ - The price decays linearly from $1000 to $150 over the 10-day auction period.
+
+2. **Sequencer Goes Offline**:
+ - After 30 minutes (1,800 seconds) of the auction running, the sequencer goes offline.
+ - During the 1-hour downtime (3,600 seconds), the auction price continues to decay, but no transactions can be processed, effectively "sticking" the auction at its offline state.
+
+3. **Sequencer Comes Back Online**:
+ - Once the sequencer returns online, the auction has decayed for a total of 1.5 hours (1,800 seconds of normal operation + 3,600 seconds of offline time).
+ - The price will now be significantly lower than expected, as the auction continued to decay during the downtime.
+
+4. **Auction Price Calculation**:
+ - The auction price is determined by the elapsed time relative to the total auction duration. The decay is linear, so after 1.5 hours, the auction price will be reduced as follows:
+
+$$
+ \[
+ \text{Price} = 1000 - \left( \frac{1000 - 150}{864000} \times 5400 \right) \approx 913.81
+ \]
+$$
+
+ - At this point, the auction price is approximately **$913.81**, despite only 1.5 hours having passed.
+
+5. **Impact of the Issue**:
+ - The buyer can now purchase Bob’s collateral at a price much lower than originally intended.
+ - Bob’s collateral is liquidated at this reduced price, and the buyer only needs to repay 91.38% of Bob's debt. If this were a collateral liquidation, the lender would receive less than expected.
+
+The issue becomes even more severe when a user creates a short-duration auction on the Debita platform or when the sequencer downtime is longer than expected.
+
+### Mitigation
+
+Implement a sequencer uptime check and invalidate the auction if the sequencer was ever down during the auction period. This would ensure that the auction price is not unfairly affected by sequencer downtime.

+### Summary
+
+Despite having off-chain monitoring bots, the `DebitaChainlink.sol` contract lacks on-chain circuit breaker protection in `getThePrice()`.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L30-L42
+
+While the protocol states it has bots to monitor and pause oracles at 5% deviations, the implementation details, monitoring frequency, and reaction time of these bots are not specified. This uncertainty, combined with the lack of on-chain circuit breaker detection, creates a critical window of vulnerability during rapid price movements where the protocol may use Chainlink's minAnswer price instead of actual market prices.
+
+### Root Cause
+
+In `DebitaChainlink.sol:getThePrice()` there is no implementation of bounds checking or circuit breaker detection mechanisms, which fails to protect against Chainlink's minimum price threshold behavior. While the protocol employs off-chain monitoring bots, their effectiveness depends on unspecified implementation details such as checking frequency, price source comparison, and pause triggering mechanisms. This makes the on-chain contract the critical line of defense.
+
+### Internal pre-conditions
+
+1. Protocol needs to have `isPaused` set to false
+2. Price feed address for the token needs to be set in `priceFeeds` mapping
+3. Price feed needs to be marked as available in `isFeedAvailable` mapping
+
+### External pre-conditions
+
+- Asset price needs to fall below Chainlink's minAnswer threshold
+- Market conditions need to be extreme enough to trigger Chainlink's circuit breaker
+- Price movement needs to outpace the bot's (unspecified) detection and response time
+
+
+### Attack Path
+
+
+1. Attacker observes asset price falling below Chainlink's minAnswer
+2. Taking advantage of the uncertain bot response window:
+ - Attacker uses protocol functions that rely on getThePrice() knowing the returned price is higher than actual market price
+ - This is particularly dangerous on L2s (Base, Arbitrum & OP) where price updates and bot reactions might be delayed
+3. Protocol processes transactions using incorrect elevated price from circuit breaker
+4. Through DebitaV3Aggregator, attacker can create lending/borrowing positions using the incorrect price before the bot can detect and pause the oracle
+
+### Impact
+
+The protocol users suffer potential significant losses as positions can become under-collateralized when true market prices deviate from the circuit breaker minimum price. This is especially concerning because:
+1. The protocol operates on multiple L2s where both price updates and bot reactions might be delayed
+2. The contract handles critical assets
+3. The effectiveness of the off-chain monitoring depends on unspecified bot implementation details including:
+ - Monitoring frequency
+ - Price comparison methodology
+ - Response time guarantees
+ - Network congestion handling
+4. All lending operations through DebitaV3Aggregator are affected until either the on-chain circuit breaker triggers or the bot successfully pauses the oracle

+# Insufficient Oracle Price Validation in DebitaChainlink.sol
+
+### Summary
+
+The `DebitaChainlink.sol` contract's `getThePrice()` function performs incomplete validation of Chainlink oracle data.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L30-L42
+
+While it implements some basic checks and L2 sequencer validation, it misses critical timestamp validations that could lead to stale prices being used.
+
+### Root Cause
+
+In `DebitaChainlink.sol:getThePrice()`, the contract only validates:
+1. Contract pause status
+2. Price feed existence
+3. Sequencer status (for L2s)
+4. Price > 0
+
+However, it fails to validate:
+1. The timestamp of the price update (`updatedAt`)
+2. Round completeness
+3. Round sequencing (`answeredInRound >= roundId`)
+
+Code snippet from `getThePrice()`:
+```solidity
+(, int price, , , ) = priceFeed.latestRoundData();
+require(isFeedAvailable[_priceFeed], "Price feed not available");
+require(price > 0, "Invalid price");
+```
+
+
+### Internal pre-conditions
+
+1. Contract must not be paused (`isPaused == false`)
+2. Price feed must be set for the token (`priceFeeds[tokenAddress] != address(0)`)
+3. Price feed must be available (`isFeedAvailable[_priceFeed] == true`)
+4. For L2s, sequencer must be up and grace period over
+
+### External pre-conditions
+
+1. Chainlink oracle returns stale data while still maintaining price > 0
+2. For L2s, sequencer is up but oracle data hasn't been updated recently
+
+### Attack Path
+
+1. Oracle data becomes stale but maintains a positive price
+2. No timestamp validation means the stale price is accepted
+3. Protocol continues using outdated price data for operations
+
+### Impact
+
+The use of stale or invalid oracle prices would directly impact the protocol's lending mechanisms:
+
+- Borrowers could secure loans with insufficient collateral if stale prices are higher than current market prices
+- Legitimate liquidations could be prevented if stale prices show higher collateral value than reality
+- False liquidations could be triggered if stale prices undervalue collateral
+- These scenarios result in direct financial losses for users and potential bad debt for the protocol
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Enhance `getThePrice()` to include full oracle data validation:
+
+```solidity
+function getThePrice(address tokenAddress) public view returns (int) {
+ address _priceFeed = priceFeeds[tokenAddress];
+ require(!isPaused, "Contract is paused");
+ require(_priceFeed != address(0), "Price feed not set");
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+
+ AggregatorV3Interface priceFeed = AggregatorV3Interface(_priceFeed);
+
+ if (address(sequencerUptimeFeed) != address(0)) {
+ checkSequencer();
+ }
+
+ (uint80 roundId, int256 price, , uint256 updatedAt, uint80 answeredInRound) = priceFeed.latestRoundData();
+
+ require(price > 0, "Invalid price");
+ require(answeredInRound >= roundId, "Stale price round");
+ require(updatedAt != 0, "Round not complete");
+ require(block.timestamp - updatedAt <= 600, "Price too old"); // Using 600s from contest scope
+
+ return price;
+}
+```
+
+Additional recommendations:
+1. Consider adding an `updatedAt` threshold variable that can be configured.
+2. Add events for price update validations to assist the monitoring bot.
+3. Consider adding a view function that returns the full price data including timestamps for external validation.

+# M-3: Due to an incorrect implementation of the `for` loop in `buyOrderFactory::getActiveBuyOrders`, the function fails to return the correct query results.
+
+### Summary
+
+The purpose of the `buyOrderFactory::getActiveBuyOrders` function is to retrieve buy order information within a specified range. However, due to an incorrect implementation of the `for` loop, the function fails to return the correct query results, as the loop causes an out-of-bounds access to the `_activeBuyOrders` array.
+
+### Root Cause
+
+```solidity
+ function getActiveBuyOrders(
+ uint offset,
+ uint limit
+ ) public view returns (BuyOrder.BuyInfo[] memory) {
+ uint length = limit;
+
+ if (limit > activeOrdersCount) {
+ length = activeOrdersCount;
+ }
+
+ BuyOrder.BuyInfo[] memory _activeBuyOrders = new BuyOrder.BuyInfo[](
+ limit - offset
+ );
+ for (uint i = offset; i < offset + limit; i++) {
+@> address order = allActiveBuyOrders[i];
+@> _activeBuyOrders[i] = BuyOrder(order).getBuyInfo();
+ }
+ return _activeBuyOrders;
+ }
+```
+
+In the [buyOrderFactory::getActiveBuyOrders](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L139-L157) function, there is an error in the implementation of the `for` loop, as the number of `orders` can exceed the length of the `_activeBuyOrders` array, leading to an out-of-bounds access.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. `getHistoricalBuyOrders`
+2. `getActiveBuyOrders`
+
+Since `getHistoricalBuyOrders` has the same issue as `getActiveBuyOrders`, I only need to clearly describe the issue with `getActiveBuyOrders`.
+
+### Impact
+
+Due to an array out-of-bounds issue in the `for` loop in `buyOrderFactory::getActiveBuyOrders`, users are unable to receive the correct query results when calling this function.
+
+### PoC
+
+To demonstrate the impact based on the description in the Root Cause:
+
+Scenario Simulation:
+
+1. Set `offset = 1`, `limit = 5`, where `limit < activeOrdersCount`.
+4. Therefore, `_activeBuyOrders.length = 4`.
+5. The `for` loop is implemented as `uint i = offset; i < offset + limit; i++`.
+6. This results in `1 <= i < 6`, meaning the loop will attempt to process 5 orders, while `_activeBuyOrders.length = 4`.
+7. Since `4 < 5`, this causes an out-of-bounds access.
+
+### Mitigation
+
+The correct `for` loop can be implemented with the following modification:
+
+```diff
+ function getActiveBuyOrders(
+ uint offset,
+ uint limit
+ ) public view returns (BuyOrder.BuyInfo[] memory) {
+ uint length = limit;
+
+ if (limit > activeOrdersCount) {
+ length = activeOrdersCount;
+ }
+
+ BuyOrder.BuyInfo[] memory _activeBuyOrders = new BuyOrder.BuyInfo[](
+ limit - offset
+ );
+- for (uint i = offset; i < offset + limit; i++) {
++ for (uint i = 0; i + offset < length; i++) {
+- address order = allActiveBuyOrders[i];
++ address order = allActiveBuyOrders[i + offset];
+ _activeBuyOrders[i] = BuyOrder(order).getBuyInfo();
+ }
+ return _activeBuyOrders;
+ }
+```

+# Missing Event Emissions in MixOracle Allow Unnoticed Critical State Changes
+
+# Issue: Missing Event Emissions in MixOracle Allow Unnoticed Critical State Changes
+
+---
+
+## Summary
+
+The lack of event emissions in critical functions within `MixOracle.sol` will cause monitoring and transparency issues for protocols integrating with the oracle, as they cannot track significant state changes or price updates due to missing event logs. This occurs because the `MixOracle` contract does not emit events during essential state changes, making it impossible for off-chain systems to detect and respond to these changes. Consequently, protocols and users relying on `MixOracle` are at risk because they cannot monitor or verify important actions within the oracle.
+
+---
+
+## Root Cause
+
+In `MixOracle.sol`, critical functions that modify the state of the oracle lack corresponding event emissions. Specifically:
+
+- **In [`MixOracle.sol:72`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/MixOracle/MixOracle.sol#L72-L95)**, the `setAttachedTarotPriceOracle` function, which sets or updates the attached Tarot price oracle, does not emit an event to signal this change.
+
+ ```solidity
+ // MixOracle.sol:72
+ function setAttachedTarotPriceOracle(address uniswapV2Pair) public {
+ // ... existing code ...
+ // Missing: emit PriceOracleSet(tokenAddress, address(tarotOracle), uniswapV2Pair);
+ }
+ ```
+
+- **In [`MixOracle.sol:40`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/MixOracle/MixOracle.sol#L40-L70)**, the `getThePrice` function, which calculates and returns the current price of a token, does not emit an event upon a price update.
+
+ ```solidity
+ // MixOracle.sol:40
+ function getThePrice(address tokenAddress) public returns (int) {
+ // ... existing code ...
+ // Missing: emit PriceUpdate(tokenAddress, price, block.timestamp);
+ return price;
+ }
+ ```
+
+- **Other Critical Functions Missing Event Emissions**:
+ - `pauseContract()`
+ - `setManager(address manager, bool status)`
+ - `changeMultisig(address newMultisig)`
+
+This lack of event emissions means that off-chain systems, monitoring tools, and integrating protocols cannot detect or respond to critical changes within the `MixOracle` contract.
+
+---
+
+## Internal Pre-conditions
+
+1. **Critical Functions Lack Event Emissions**:
+ - The `MixOracle` contract's critical functions (`setAttachedTarotPriceOracle`, `getThePrice`, `pauseContract`, `setManager`, `changeMultisig`) do not emit events when they perform significant state changes.
+2. **No Alternative Notification Mechanisms**:
+ - There are no other mechanisms within the contract to notify external systems of these state changes.
+
+---
+
+## External Pre-conditions
+
+1. **Dependence on Event Logs**:
+ - Protocols and monitoring tools that integrate with `MixOracle` rely on event logs to track state changes and price updates.
+2. **Need for Transparency and Auditing**:
+ - Users, auditors, and compliance systems require event logs to verify actions taken by the oracle for transparency and security purposes.
+
+---
+
+## Attack Path
+
+Although this issue is not an attack in the traditional sense, it represents a vulnerability path where critical changes can occur unnoticed, potentially leading to security risks.
+
+1. **Admin Makes Critical Changes Without Emitting Events**:
+ - The admin calls `setAttachedTarotPriceOracle(address uniswapV2Pair)` to set or change the price oracle.
+ - **Issue**: No `PriceOracleSet` event is emitted, so integrating protocols and monitoring systems are unaware of this change.
+
+2. **State Changes Occur Without Detection**:
+ - Functions like `pauseContract`, `setManager`, and `changeMultisig` are called, altering the operational state of the oracle.
+ - **Issue**: Without events, external systems cannot detect these changes in real-time.
+
+3. **Price Updates Happen Without Notifications**:
+ - When `getThePrice(address tokenAddress)` is called and a new price is calculated, no event is emitted.
+ - **Issue**: Off-chain systems cannot track price changes or verify the accuracy of the oracle's output.
+
+---
+
+## Impact
+
+Protocols and users relying on the `MixOracle` suffer from the inability to monitor critical state changes and price updates, leading to:
+
+- **Security Risks**:
+ - Unauthorized or malicious changes to the oracle's state may go undetected, allowing potential exploitation by attackers.
+- **Operational Failures**:
+ - Integrating protocols may continue operating under outdated or incorrect assumptions, leading to financial losses or system malfunctions.
+- **Lack of Transparency**:
+ - Users and stakeholders cannot audit or verify critical actions, reducing trust in the protocol.
+- **Compliance and Regulatory Issues**:
+ - Protocols requiring audit trails and transparency for regulatory compliance cannot fulfill these requirements, potentially leading to legal consequences.
+- **Monitoring and Alerting Failures**:
+ - Without event emissions, automated monitoring and alerting systems cannot function, preventing timely responses to critical issues.
+

+
+### Test Case: Missing Event Emissions in `MixOracle`
+
+```solidity
+// SPDX-License-Identifier: MIT

+ // Call the function that should emit the event
+ oracle.changeMultisig(newMultisig);
+
+ vm.stopPrank();
+
+ // Test fails because the event is not emitted
+ }
+}
+```
+
+**Test Output:**
+
+```plaintext
+[FAIL] testMissingPriceOracleSetEvent() (gas: 258975)
+[FAIL] testMissingPriceUpdateEvent() (gas: 259123)
+[FAIL] testMissingMultisigChangedEvent() (gas: 259081)
+```
+
+*The tests fail because the expected events are not emitted when the critical functions are called.*
+
+---
+
+## Mitigation
+
+### 1. **Add Event Definitions in `MixOracle.sol`**
+
+Define events for all functions that perform significant state changes:
+
+```solidity
+event PriceOracleSet(address indexed token, address indexed oracle, address indexed uniswapPair);
+event PriceUpdate(address indexed token, int price, uint timestamp);
+event MultisigChanged(address indexed oldMultisig, address indexed newMultisig);
+event OracleStatusChanged(address indexed oracle, bool isPaused);
+event ManagerStatusChanged(address indexed manager, bool status);
+```
+
+### 2. **Emit Events in Critical Functions**
+
+Update each critical function to emit the appropriate event when it is called.
+
+- **In `setAttachedTarotPriceOracle`:**
+
+ ```solidity
+ function setAttachedTarotPriceOracle(address uniswapV2Pair) public {
+ // ... existing code ...
+ emit PriceOracleSet(tokenAddress, address(tarotOracle), uniswapV2Pair);
+ }
+ ```
+
+- **In `getThePrice`:**
+
+ ```solidity
+ function getThePrice(address tokenAddress) public returns (int) {
+ // ... existing code ...
+ emit PriceUpdate(tokenAddress, price, block.timestamp);
+ return price;
+ }
+ ```
+
+- **In `changeMultisig`:**
+
+ ```solidity
+ function changeMultisig(address newMultisig) external {
+ address oldMultisig = multisig;
+ multisig = newMultisig;
+ emit MultisigChanged(oldMultisig, newMultisig);
+ }
+ ```
+
+- **In `pauseContract`:**
+
+ ```solidity
+ function pauseContract() external {
+ isPaused = true;
+ emit OracleStatusChanged(address(this), true);
+ }
+ ```
+
+- **In `setManager`:**
+
+ ```solidity
+ function setManager(address manager, bool status) external {
+ managers[manager] = status;
+ emit ManagerStatusChanged(manager, status);
+ }
+ ```
+
+### 3. **Update Tests to Confirm Event Emissions**
+
+Re-run the test cases to ensure events are now emitted, and all tests pass.
+
+**Updated Test Output:**
+
+```plaintext
+[PASS] testMissingPriceOracleSetEvent() (gas: 260000)
+[PASS] testMissingPriceUpdateEvent() (gas: 260150)
+[PASS] testMissingMultisigChangedEvent() (gas: 260110)
+```
+
+---
+
+## Conclusion
+
+By adding the missing event emissions to the critical functions in `MixOracle.sol`, the protocol can ensure that off-chain systems and users can effectively monitor and react to important state changes and price updates. This enhances transparency, improves security, and facilitates compliance with audit requirements.

+# `changeOwner` function argument shadows `owner` variable, preventing authorized owner from updating ownership in contracts
+
+### Summary
+
+The `changeOwner` function is implemented to allow the contract deployer to update the contract owner within six hours of deployment. However, the function's parameter `address owner` shadows the `owner` state variable, leading to the following unintended behaviour:
+
+- The `msg.sender` is incorrectly compared to the function parameter instead of the state variable.
+- This causes the function to revert unless `msg.sender` matches the argument passed, preventing the current owner from updating ownership.
+
+As a result, ownership transfer functionality is entirely broken. This issue affects the `DebitaV3Aggregator`, `auctionFactoryDebita`, and `buyOrderFactory` contracts.
+
+### Root Cause
+
+In the `changeOwner` function implemented in the [DebitaV3Aggregator](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682-L686), [auctionFactoryDebita](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L218-L222) and [buyOrderFactory](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L186-L190) contracts the argument shadows the `owner` state variable and the `msg.sender` is compared with the argument instead of the `owner` state variable.
+
+```solidity
+ function changeOwner(address owner) public {
+@> require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+```
+
+### Internal pre-conditions
+
+In the `DebitaV3Aggregator`, `auctionFactoryDebita`, and `buyOrderFactory` contracts, the `block.timestamp` must be less than `deployedTime + 6 hours`
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. The contract owner attempts to transfer ownership by calling the `changeOwner` function and passing the desired new owner address as the argument.
+2. Inside the `changeOwner` function, due to the `owner` variable shadowing, the `require` statement compares `msg.sender` (the current contract owner's address) with the argument provided, instead of the `owner` state variable:
+
+```solidity
+require(msg.sender == owner, "Only owner");
+```
+3. Since `msg.sender` does not match the argument (the desired new owner's address), the function reverts, preventing the ownership transfer and leaving the owner unable to assign a new owner.
+
+### Impact
+
+The affected contracts (`DebitaV3Aggregator`, `auctionFactoryDebita`, `buyOrderFactory`) lose their ability to transfer ownership.

+}
+```
+
+
+Steps to reproduce:
+
+1. Create a file `ChangeOwnerTest.t.sol` inside `Debita-V3-Contracts/test/local/` and paste the PoC code.
+
+2. Run the test in the terminal with the following command:
+
+`forge test --mt testChangeOwner`
+
+### Mitigation
+
+In the `DebitaV3Aggregator`, `auctionFactoryDebita`, and `buyOrderFactory` contracts, modify the `changeOwner` function to avoid shadowing the `owner` state variable and to ensure the `owner` state variable is updated correctly:
+
+```diff
+- function changeOwner(address owner) public {
++ function changeOwner(address _owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+- owner = owner;
++ owner = _owner;
+ }
+```
+
+This change allows the authorized owner to modify the contract ownership as intended.

+### Summary

+
+```solidity
+ function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+```
+The function parameter has the same name of global var name in protocol. https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L198
+The `owner = owner` will not change the value of global var. So `msg.sender` will not change the owner.

+# Protocol Will Unable to Retrieve The Price from Pyth
+
+### Summary
+
+Oracle in `DebitaPyth.sol` doesn't follow the required step to return the price.
+
+
+### Root Cause
+
+In [DebitaPyth.sol::getThePrice](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L25), there is 2 lines of code missing. The missing code is fee related and mandatory for the oracle to work correctly and precisely.
+
+If you check the [docs](https://docs.pyth.network/price-feeds/use-real-time-data/evm), updating the price requires paying the fee returned by getUpdateFee and this step is imporant to ensure the getPriceNoOlderThan call succeeds without any error.
+
+
+
+```solidity
+ function getThePrice(address tokenAddress) public view returns (int) {
+ // falta hacer un chequeo para las l2
+ bytes32 _priceFeed = priceIdPerToken[tokenAddress];
+ require(_priceFeed != bytes32(0), "Price feed not set");
+ require(!isPaused, "Contract is paused");
+
+ // fee line is required for the transaction to be succeed. Check https://docs.pyth.network/price-feeds/use-real-time-data/evm
+
+ // Get the price from the pyth contract, no older than 90 seconds
+ PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ _priceFeed,
+ 600
+ );
+
+ // Check if the price feed is available and the price is valid
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+ require(priceData.price > 0, "Invalid price");
+ return priceData.price;
+ }
+```
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. The protocol use Pyth Oracle to return the price.
+2. Instead of returning the price, it returns an error and transaction may fail.
+
+### Impact
+
+Unable to retrieve the price as the protocol wanted.
+
+
+### PoC
+
+_No response_
+
+### Mitigation

+# Limit for lend orders array passed to `matchOffersV3()` is to high, leading to out of gas on certain chains
+
+### Summary
+
+Practical call flow leading to OOG exception exists on Sonic & Arbitrum chains. `matchOffersV3()` function execution is costly due to repeating many operations up to a `lendOrders.length` times.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L396
+For large enough, but within predefined boundaries (<=100 orders) `lendOrders` array the gas exceeds block gas limit on some chains the protocol will be deployed to.
+
+### Root Cause
+
+`lendOrders.length` limit is set to high considering the increasing cost of executing `matchOffersV3()` function.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L290
+
+### Internal pre-conditions
+
+- the protocol is used on either Arbitrum or Sonic ( other chains have larger block gas limit )
+- a user/bot calling `matchOffersV3()` uses a large amount of lend orders in an attempt to fill large borrow order
+
+### External pre-conditions
+
+- Arbitrum block gas limit of 32,000,000 gas
+- Sonic block gas limit of 31,000,000 gas
+
+### Attack Path
+
+--
+
+### Impact
+
+Calling `matchOffersV3()` with some of the **allowed** amounts of lend orders will cause an out of gas error - rendering core functionality broken under certain conditions.
+
+
+### PoC
+
+Even though the protocol will be deployed on L2s, the gas limit can easily be reached on 2/4 chains from the README:
+1. Optimism : 60,000,000 block gas limit
+2. Base : 180,000,000 block gas limit
+3. Arbitrum : 32,000,000 block gas limit ( effective )
+4. Sonic : 31,000,000 block gas limit

+
+
+For instance, the test from the dropdown above is an example of calling `matchOffersV3()` with 100 lend orders all for 1 principle that is shown to cost 46,913,300 gas. This exceeds the block gas limit on Arbitrum and Sonic chains. Due to a completely unrelated root cause, any call to `matchOffersV3()` with more than 29 lend orders will revert - stil, 100 lend orders should be allowed therefore this PoC should be runnable. To fix this limitation of 29 lend orders modify the following line in `DebitaV3Loan`:
+
+```diff
++ require(_acceptedOffers.length <= 100, "Too many offers");
+- require(_acceptedOffers.length < 30, "Too many offers");
+
+```
+
+Modifying contracts for the PoC is a bad practice, however, in this case, it needs to be done due to this unrelated root cause of assuming that `lendOrders.length` might be `!=` to `_acceptedOffers.length`.
+
+After this change, create a test file with code from the gist and run it with:
+```shell
+forge test --mt test_matchOffersOutOfGas --mc PoC -vvv
+```
+
+On Optimism this tx fits into the block and costs ~$7 ( 0.05 Gwei - current gas price ) and on Base ~$17 ( 0.12 Gwei - current gas price ) - so on these chains, it does not lead to OOG. However, it's worth noting that on Optimism this tx uses ~78% of the block gas limit, which might require a significant increase in the gas price to include this tx during periods of high network congestion.
+
+
+
+### Mitigation
+
+Significantly decrease the maximum amount of lend orders allowed in `matchOffersV3()`.

+# Due to incorrect `claimCollateralAsLender()` implementation a lender can lose access to NFT collateral after liquidation
+
+### Summary
+
+When a loan based on NFT collateral is liquidated the lender has two options for claiming it:
+1. Create an auction for the NFT and after it is bought claim the underlying ERC20s.
+2. Claim the NFT directly - possible ONLY when they are a lonely lender ( `m_loan._acceptedOffers.length == 1` ).
+Calling `claimCollateralAsLender()` when both of these conditions are not met should result in an error - suggesting that the lender should create an auction first. However, when this function is called in this situation, lender's ownership NFT is burned while the function returns without transferring the collateral.
+
+### Root Cause
+
+`claimCollateralAsNFTLender()` function returns a boolean indicating whether the collateral is claimed. Unfortunately, in `claimCollateralAsLender()` this return value is ignored :
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L360-L361
+because of this, the ownership NFT is burned even though the lender failed to claim collateral.
+
+### Internal pre-conditions
+
+- liquidation of a loan with NFT collateral has occurred
+- lender calls the function in a specific state ( auction was not initialized and there are more than 1 lend offers matched in that loan )
+
+### External pre-conditions
+
+--
+
+### Attack Path
+
+--
+
+### Impact
+
+Permanent loss of significant funds for the lender due to a simple mistake call that should always revert. Lenders should not lose the right to claim liquidated collateral under ANY circumstances. Here the issue requires a specific state to happen, but lost funds can be arbitrarily large - depending on the collateral's value even thousands of $.
+
+
+### PoC
+
+The PoC shows exactly how all funds are lost after an unsuccessful call to `claimCollateralAsLender()` due to a lack of ownership token.
+
+Place the following test case in `OracleOneLenderLoanReceipt.t.sol` file:
+```solidity
+ error ERC721NonexistentToken(uint);
+ // testDefaultAndAuctionCall test modified to simulate the mistake call and prove permanent loss of funds
+ function test_lenderCanLoseCollateral() public {
+ MatchOffers();
+ uint[] memory indexes = allDynamicData.getDynamicUintArray(1);
+ indexes[0] = 0;
+ vm.warp(block.timestamp + 8640010);
+
+ // Here, the auction should have been initialized and NFT sold
+
+ // claim sold Amount
+ uint balanceBefore = AEROContract.balanceOf(lender);
+ DebitaV3LoanContract.claimCollateralAsLender(0);
+ uint balanceAfter = AEROContract.balanceOf(lender);
+ assertEq(balanceBefore, balanceAfter);
+
+ vm.expectRevert(abi.encodeWithSelector(ERC721NonexistentToken.selector, 1));
+ DebitaV3LoanContract.claimCollateralAsLender(0);
+
+ }
+```

+# M-4: The `buyOrderFactory::_deleteBuyOrder` allows an attacker to delete the `buyOrder` records of any other user on the contract due to access control issues.
+
+### Summary
+
+The function `buyOrderFactory::_deleteBuyOrder` allows an attacker to delete the buyOrder records of any other user on the contract due to access control issues. This is because the function only verifies the existence of the buyOrder and ignores the fact that a buyOrder should only be deletable by its owner.
+
+### Root Cause
+
+In [buyOrderFactory::_deleteBuyOrder](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L127-L137), there is an access control issue that allows an attacker to delete the buyOrder records of any other user on the contract.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. The attacker creates a legitimate buyOrder, which sets `isBuyOrderLegit[attacker] = true`.
+2. The attacker can then call `_deleteBuyOrder(victimAddress)`.
+3. This allows the attacker to delete the buyOrder of any other user.
+
+### Impact
+
+The attacker can create a valid buyOrder and then delete the buyOrder records of other users on the contract.
+
+### PoC
+
+A simplified POC demonstrating the impact. It needs to be run in Remix.
+
+User A: 0x5B38Da6a701c568545dCfcB03FcB875f56beddC4
+User B: 0xAb8483F64d9C6d1EcF9b849Ae677dD3315835cb2
+
+1. When User A deploys the contract and calls `deposit()`, they can then call `test()` to execute related actions.
+2. At this point, if User B also calls `deposit()`, `isVaultValid[msg.sender] = true;` will be set, and User B can successfully call `test()` to execute related actions as well.
+3. In a real-world scenario, this would allow a malicious user to create a valid buyOrder and then call `buyOrderFactory::_deleteBuyOrder` to delete the buyOrders created by other users!
+
+```solidity
+// SPDX-License-Identifier: MIT
+pragma solidity ^0.8.26;
+
+contract HelloWorld {
+ mapping(address => bool) internal isVaultValid;
+ modifier onlyVault() {
+ require(isVaultValid[msg.sender], "not vault");
+ _;
+ }
+
+ function deposit() external {
+ isVaultValid[msg.sender] = true;
+ }
+
+ function test() external onlyVault{
+ // ... Call Success
+ }
+}
+```
+
+### Mitigation
+
+It is recommended to add `msg.sender == _buyOrder` for further validation.
+
+```diff
+ function _deleteBuyOrder(address _buyOrder) public onlyBuyOrder {
++ require(msg.sender == _buyOrder, "Can only delete own order");
+ uint index = BuyOrderIndex[_buyOrder];
+ BuyOrderIndex[_buyOrder] = 0;
+
+ allActiveBuyOrders[index] = allActiveBuyOrders[activeOrdersCount - 1];
+ allActiveBuyOrders[activeOrdersCount - 1] = address(0);
+
+ BuyOrderIndex[allActiveBuyOrders[index]] = index;
+
+ activeOrdersCount--;
+ }

+# Short loans with <5 day duration cannot be extended due to incorrect logic
+
+### Summary
+
+The `extendLoan()` function will calculate the missing borrow fee that has to be paid to account for the extra duration. The `feeOfMaxDeadline` value is calculated incorrectly, but this is a separate finding - so let's assume it does what it should: calculates the fee for a loan of `lendInfo.maxDuration` duration. It's possible that the borrower decided on a short-term loan with 3a -day duration, but after >10% of the 3 days they attempted to extend it. Due to incorrect logic the call to `extendLoan()` will revert for any short loans when any of the unpaid lend offers have a max duration of < 5 days.
+
+
+### Root Cause
+
+The `feeOfMaxDeadline` value is checked against `feePerDay` instead of `minFee`:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L606-L608
+So when `feeOfMaxDeadline` is less than `0.2%`, it will not change ( unless it's a VERY short loan where lend offer `maxDuration` is <1 day which is unlikely and the issue still persists ). This will lead to underflow revert for any lend offer with `maxDuration` less than 5 days:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L610
+This is because if `maxDuration` is less than 5 days the `initialDuration` of the loan must be less than that as well, and in that case `PorcentageOfFeePaid` equal to `minFee` or `0.2%` is larger than `feeMaxDuration`.
+
+### Internal pre-conditions
+
+- loan with `initialDuration` less than 5 days is created
+- at least one of the lending offers from that loan has a `maxDuration` larger than `initialDuration` but still below 5 day mark
+- borrower attempts to extend such loan when one of the lending offers from the previous point is still unpaid
+Essentially, an attempt to extend a short-term loan.
+
+
+### External pre-conditions
+
+--
+
+### Attack Path
+
+--
+
+### Impact
+
+Extension functionality is completely broken for loans with <5 day duration due to an unwanted underflow revert.
+
+
+### PoC
+
+
+For the PoC to work, change the duration of the borrow order to `259200` (3 days):
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/test/fork/Loan/ltv/OracleOneLenderLoanReceipt.t.sol#L135
+and the max duration for the lend order to `302400` (3.5 days):
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/test/fork/Loan/ltv/OracleOneLenderLoanReceipt.t.sol#L154
+
+Unfortunately, the `extendLoan()` function has a separate root cause which cause the `feeOfMaxDeadline` to always be larger than `maxFee` - this is explained in another finding. To successfully even REACH the `if else` branch, the following change is necessary :
+```solidity
+ uint feeOfMaxDeadline = (((offer.maxDeadline - m_loan.startedAt) * feePerDay) /
+ 86400);
+```
+The details of why this is needed are in the separate finding.
+
+Add the following test case to the test file:
+```solidity
+ function test_shortLoanCannotBeExtended() public {
+ MatchOffers();
+ uint[] memory indexes = allDynamicData.getDynamicUintArray(1);
+ indexes[0] = 0;
+ vm.startPrank(borrower);
+
+ AEROContract.approve(address(DebitaV3LoanContract), 100e18);
+ vm.warp(block.timestamp + 86400); // 1/3 days of the loan pass
+ vm.expectRevert(stdError.arithmeticError);
+ DebitaV3LoanContract.extendLoan();
+ }
+
+```
+and import `stdError`:
+```diff
+-import {Test, console} from "forge-std/Test.sol";
++import {Test, stdError, console} from "forge-std/Test.sol";
+```
+Run it with:
+```shell
+ forge test --fork-url https://mainnet.base.org --fork-block-number 21151256 --mt test_shortLoanCannotBeExtended
+```
+
+
+### Mitigation
+
+Use `minFEE` instead of `feePerDay` for `feeOfMaxDeadline` validation:
+```diff
+ } else if (feeOfMaxDeadline < minFEE) {
+ feeOfMaxDeadline = minFEE;
+ }
+```

+# Duplication of struct name causes `DebitaLendOfferFactory::getActiveOrders` to revert every time it is called with the wrong struct as the datatype.
+
+### Summary
+
+2 similar structs `LendInfo` defined in [`DebitaLendOfferFactory.sol`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L8) and [`DebitaLendOffer-Implementation.sol`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L26) might cause the function `getActiveOrders` to revert every single time if the incorrect struct is used as the return datatype. This will cause the users to not get the updates they need to make decisions on the platform.
+
+### Root Cause
+
+The function [`getActiveOrders`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L222) returns `DLOImplementation.LendInfo[] memory` which is the `LendInfo` struct defined in the `DebitaLendOfferFactory.sol` file. When a user calls the `getActiveOrders` function, they will need to double-check that they are using the correct struct. If they use the incorrect struct, they will be introduced to the following very confusing error:
+
+`Type struct DLOImplementation.LendInfo[] memory is not implicitly convertible to expected type struct DLOImplementation.LendInfo[] memory.`
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+Users using the wrong struct to call the function might cause them to miss out and probably lose out on good investments because of the confusing nature of the smart contract.
+
+### PoC
+
+Add the following test in `Debita-V3-Contracts/test/local/Aggregator/BasicDebitaAggregator.t.sol`.
+
+```solidity
+function test_checking_LendInfo() public {
+ DLOImplementation.LendInfo[] memory active_lend_orders;
+ active_lend_orders = DLOFactoryContract.getActiveOrders(0, 100);
+ }
+```
+
+Run the test with `forge test --mt test_checking_LendInfo -vvv`.
+It will revert with the error:
+
+`Type struct DLOImplementation.LendInfo[] memory is not implicitly convertible to expected type struct DLOImplementation.LendInfo[] memory.`
+
+To make sure that it works add the following into the beginning of `Debita-V3-Contracts/test/local/Aggregator/BasicDebitaAggregator.t.sol`:
+
+```solidity
+import {DLOImplementation as DLOImplementation2} from "@contracts/DebitaLendOfferFactory.sol";
+```
+
+Now, replace the code with:
+
+```solidity
+function test_checking_LendInfo() public {
+ DLOImplementation2.LendInfo[] memory active_lend_orders;
+ active_lend_orders = DLOFactoryContract.getActiveOrders(0, 100);
+ }
+```
+
+Now the function works. The fact that there is a contract, and an interface with the same name that causes reverts if the imports are mixed up will cause a lot of problems in the deployment, as well as future maintenance of the code.
+
+### Mitigation
+
+The easiest way to mitigate this function is to do the following in `Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol`:
+
+```diff
+import "@openzeppelin/contracts/token/ERC20/IERC20.sol";
+import "@openzeppelin/contracts/token/ERC20/utils/SafeERC20.sol";
+import "@contracts/DebitaProxyContract.sol";
++import "@contracts/DebitaLendOffer-Implementation.sol";
+
+-interface DLOImplementation {
+- struct LendInfo {
+- address lendOrderAddress;
+- bool perpetual;
+- bool lonelyLender;
+- bool[] oraclesPerPairActivated;
+- uint[] maxLTVs;
+- uint apr;
+- uint maxDuration;
+- uint minDuration;
+- address owner;
+- address principle;
+- address[] acceptedCollaterals;
+- address[] oracle_Collaterals;
+- uint[] maxRatio;
+- address oracle_Principle;
+- uint startedLendingAmount;
+- uint availableAmount;
+- }
+-
+- function getLendInfo() external view returns (LendInfo memory);
+- function isActive() external view returns (bool);
+-
+- function initialize(
+- address _aggregatorContract,
+- bool _perpetual,
+- bool[] memory _oraclesActivated,
+- bool _lonelyLender,
+- uint[] memory _LTVs,
+- uint _apr,
+- uint _maxDuration,
+- uint _minDuration,
+- address _owner,
+- address _principle,
+- address[] memory _acceptedCollaterals,
+- address[] memory _oracles_Collateral,
+- uint[] memory _ratio,
+- address _oracleID_Principle,
+- uint _startedLendingAmount
+- ) external;
+-}
+```
+
+Importing the implementation from the main file will ensure that code is not unnecessarily duplicated in different files causing unnecessary reverts, and errors.

+# Confidence Intervals of Pyth Network's Prices Are Ignored
+
+### Summary
+
+The ``DebitaPyth.sol`` contract utilizes the Pyth Netowrk for fetching prices. However as can be seen from the [DebitaPyth::getThePrice(()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L25-L41) function:
+```solidity
+ function getThePrice(address tokenAddress) public view returns (int) {
+ // falta hacer un chequeo para las l2
+ bytes32 _priceFeed = priceIdPerToken[tokenAddress];
+ require(_priceFeed != bytes32(0), "Price feed not set");
+ require(!isPaused, "Contract is paused");
+
+ // Get the price from the pyth contract, no older than 90 seconds
+ PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ _priceFeed,
+ 600
+ );
+
+ // Check if the price feed is available and the price is valid
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+ require(priceData.price > 0, "Invalid price");
+ return priceData.price;
+ }
+```
+the protocol completely ignores the confidence interval provided by the price feed. The prices fetched by the Pyth network come with a degree of uncertainty which is expressed as a confidence interval around the given price values. Considering a provided price `p`, its confidence interval `σ` is roughly the standard deviation of the price's probability distribution. The [official documentation of the Pyth Price Feeds](https://docs.pyth.network/documentation/pythnet-price-feeds/best-practices#confidence-intervals) recommends some ways in which this confidence interval can be utilized for enhanced security. For example, the protocol can compute the value `σ / p` to decide the level of the price's uncertainty and disallow user interaction with the system in case this value exceeds some threshold. Keep in mind that borrowers and lenders may use different oracles(Chainlink, Pyth, Custom oracle), or rely on ratios for setting the amount of tokens they would like to lend/borrow. If one of the parties relies on uncertain prices, this may result in a loss for said party.
+

+# The `feeAddress` will never receive fees when users use token with higher price like ETH, BNB etc.
+
+## Summary
+
+When users use a token with higher price, majority of operations normally in small amount transaction. The fee calculation sometimes will be zero. So it's will affect to the `feeAddress` that it's never receive fees as expected.
+
+## Vulnerability detail
+
+When creating an Auction, a user can set a token for payment whatever they want. Logically, it's never impact to the protocol. But if we see at the codebase which calculating fee, it's possible to get zero amount.
+ Let's see code below :
+ https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L124
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L120-L121
+
+The protocol calculating fee for any operation like auction and buy orders. Both of them perform calculations that lead a zero amount fee. There are conditions where fee would be zero. Let's say we have worst case with lowest `fee = 50` and the denominator always `10_000`.
+- Auction with 0.5% fees of token, the price must be higher than 200 tokens to avoid zero fee,
+- Buy orders with 0.5% fees of token, the price must be higher than 200 tokens to avoid zero fee.
+
+
+## Poc
+
+For the clear explanation, let's create an example :
+1. A user want to create an auction with value 60_000 USDC
+2. But, a user uses BNB token. Lets say current price is 600 USDC / BNB
+3. So, the actual price is 60_000 USD / 600 -> 100 BNB
+4. `feeAmount` = (amount on BNB * 50) / 10_000 -> (100 * 50) / 10_000 -> 5_000 / 10_000 -> 0 of BNB
+5. The final `feeAmount` is 0 BNB
+
+## Recommendation
+
+Consider to strict a token payment like stablecoin USDC to avoid this issue

+# When a buyOrder is completed the NFT will be locked in the contract forever
+
+### Summary
+
+The ``buyOrder.sol`` contract allows users to provide amount of a certain collateral and create a buy order, and in exchange allow other users to fill said buy order by providing a veNFT that has been locked in the ``Receipt-veNFT.sol`` contract. Once the buy order is created users which hold such receipts for veNFTs can call the [sellNFT()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L92-L141) function:
+```solidity
+ function sellNFT(uint receiptID) public {
+ require(buyInformation.isActive, "Buy order is not active");
+ require(
+ buyInformation.availableAmount > 0,
+ "Buy order is not available"
+ );
+
+@-> IERC721(buyInformation.wantedToken).transferFrom(
+ msg.sender,
+ address(this),
+ receiptID
+ );
+ veNFR receipt = veNFR(buyInformation.wantedToken);
+ veNFR.receiptInstance memory receiptData = receipt.getDataByReceipt(
+ receiptID
+ );
+ uint collateralAmount = receiptData.lockedAmount;
+ uint collateralDecimals = receiptData.decimals;
+
+ uint amount = (buyInformation.buyRatio * collateralAmount) /
+ (10 ** collateralDecimals);
+ require(
+ amount <= buyInformation.availableAmount,
+ "Amount exceeds available amount"
+ );
+
+ buyInformation.availableAmount -= amount;
+ buyInformation.capturedAmount += collateralAmount;
+ uint feeAmount = (amount *
+ IBuyOrderFactory(buyOrderFactory).sellFee()) / 10000;
+ SafeERC20.safeTransfer(
+ IERC20(buyInformation.buyToken),
+ msg.sender,
+ amount - feeAmount
+ );
+
+ SafeERC20.safeTransfer(
+ IERC20(buyInformation.buyToken),
+ IBuyOrderFactory(buyOrderFactory).feeAddress(),
+ feeAmount
+ );
+
+ if (buyInformation.availableAmount == 0) {
+ buyInformation.isActive = false;
+ IBuyOrderFactory(buyOrderFactory).emitDelete(address(this));
+ IBuyOrderFactory(buyOrderFactory)._deleteBuyOrder(address(this));
+ } else {
+ IBuyOrderFactory(buyOrderFactory).emitUpdate(address(this));
+ }
+ }
+```
+However as can be seen from the above code snippet the NFT will be transferred to an instance of the ``buyOrder.sol`` contract, not the owner of the buyOrder itself. There are no functions in the ``buyOrder.sol`` contract, that allows the owner to transfer that NFT to a different account. This results in the NFT being locked forever in the contract. Keep in mind that veNFTs also have a manager, which can call certain functions, however the manager is not changed when the transfer happens, and the manager can only be changed by the current manager or the owner of the receipt NFT(which in this case will be the buyOrder contract), by calling the [veNFTAerodrome::changeManager()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/veNFTS/Aerodrome/veNFTAerodrome.sol#L110-L123) function.

+# Later deadline lender might liquidate borrower's collateral before their `maxDeadline` due to `claimCollateralAsLender` function checking earliest deadline of the lender.
+
+### Summary
+
+When the borrower calls `extendLoan` function then the repay time extends with lender's `maxDeadline`, if they all not have been paid yet. However the `claimCollateralAsLender` function can be called by all lender, if the earliest deadline has been passed among all the lender. So the problem is other lenders might forcefully call this function to liqiuidate borrower's collateral before their `maxDeadline`.
+
+The purpose of the `maxDeadine` is that any borrower can repay lender's debt within this time period, and his collateral should not be liquidated before that time.
+
+### Root Cause
+
+The `claimCollateralAsLender` function checks the time to liquidate the borrower collateral by earliest lender's `maxdeadline` among all lenders.

+# Lack of Checks for Decimals from Chainlink Oracle in `DebitaV3Aggregator::matchOffersV3`
+
+### Summary
+
+There is a missing check on the number of decimals in the [`DebitaChainlink::getThePrice`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L30) function. Orders can be initialized to use the Chainlink oracle to get prices for [`priceCollateral_BorrowOrder`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L309), and [`pricePrinciple`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L334) in the `matchOffersV3` function. If the oracle returns prices with different decimals, it will cause the ratio to be calculated wrong. It will result in the function either reverting, or at the worst matching the wrong borrow and lend offers.
+
+**Note: The same vulnerability is also present in the [lend order](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L440) but this report will only go through the borrow order's part of the `matchOffersV3` function because the formula is almost the same when calculating the ratio, and it shares the same root cause.**
+
+### Root Cause
+
+Since there is no checks for the decimals of the returned price from the Chainlink oracle, and the outputs are directly used in the following [calculation](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L350):
+
+$$ValuePrincipleFullLTVPerCollateral = \frac{priceCollateral\\_BorrowOrder \times 10^8}{pricePrinciple}$$
+
+$$value = \frac{(ValuePrincipleFullLTVPerCollateral \times borrowInfo.LTVs[indexForPrinciple\\_BorrowOrder[i]])}{10000}$$
+
+```solidity
+uint principleDecimals = ERC20(principles[i]).decimals()
+```
+This principles is different than the principles price returned by the oracle.
+
+$$ratio = \frac{value \times (10^{principleDecimals})}{10^8}$$
+
+There are many pairs in the Chainlink Oracle like `eth/usd` that returns a value with `8` decimals, and `usdc/eth` or `ampl/usd` that returns a value with `18` decimals. `ampl` is an ERC-20 token, which this protocol should be able to support based on the README.
+
+Here are the possible scenarios that will follow:
+
+### 1. Collateral Price has `8` decimals and Principle Price has `18` decimals:
+When dividing in the first equation `Collateral * 10**8 / Principle` will result in the following math:
+
+$$\frac{x \times 10^8 \times 10^7}{y \times 10^{18}} = \frac{x \times 10^{15}}{y \times 10^{18}}$$
+
+In all cases where the Collateral Price is less than `1000`, solidity will give an answer of `0`.
+
+### 2. Collateral Price has `18` decimals and Principle Price has `8` decimals:
+When dividing in the first equation `Collateral * 10**8 / Principle` will result in the following math:
+
+$$\frac{x \times 10^{18} \times 10^7}{y \times 10^8} = \frac{x \times 10^{25}}{y \times 10^8}$$
+
+This will result in a huge ratio.
+
+### 3. Both Collateral Price and Principle Price has the same number of decimals
+This will not cause any issues and this is probably how the function is supposed to run.
+
+Scenarios 1 & 2 will always give the wrong ratio.
+
+### Internal pre-conditions
+
+1. User needs to create a Borrow Order or Lend Order with the Chainlink Oracle's price feed.
+2. The Chainlink Oracle needs to output the price feed with different decimals for a principle, and a collateral.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+Fulfilling the pre-conditions, this will cause the ratio of a pair of collateral and principle to **ALWAYS** return the wrong ratio. With the wrong ratio, it might revert, or it might match orders incorrectly or not optimally.
+
+Attackers can always reverse-engineer the math and put in a lend offer or borrow offer that will be highly favorable to them, and result in loss of funds for the users.
+
+The fact that fulfilling the pre-conditions are in the hands of the attacker, and that Chainlink might be the oracle of choice for a majority of the users, this vulnerability will cause loopholes for attackers to open attractive lend/borrow offers that cause loss of funds for honest users.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Consider writing a function that will normalize all the Chainlink Oracle's output to a standard decimal count of your choice.

+# Lack of change owner functional implementation in some contracts
+
+### Summary
+
+The `DebitaLoanOwnerships`, `DebitaV3Aggregator`, `DebitaPyth`, `DebitaChainlink`, `AuctionFactory`, `BuyOrderFactory` contracts have functionality to change the [contract owner](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682), while the `DBOFactory`, `DLOFactory`, `DebitaIncentives` contracts do not have this functionality.
+
+And if in `DBOFactory` and `DLOFactory` contracts it can be considered as designChoice, because owner sets only one parameter there and that once. But in the `DebitaIncentives` contract the owner controls the functions `deprecatePrinciple`, `whitelListCollateral`.
+Thus, the lack of owner change functionality in this contract is an issue, because other contracts implement this functionality.
+
+### Root Cause
+
+Contracts `DBOFactory`, `DLOFactory`, `DebitaIncentives` doesnt support owner change functionality in contrast to other contracts of the protocol.
+
+### Internal pre-conditions
+
+If other contracts change owner for any reason - for example the address of the previous owner will be compromised. This will not be possible in the above contracts.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+No special attack path
+
+### Impact
+
+The protocol loses key functionality in some contracts while it is present in others.

+# Broken change owner functionality in `Aggregator`, `AuctionFactory`, `BuyOrderFactory` contracts
+
+### Summary
+
+Here's how the change owner [function](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682) is implemented in these contracts.
+```solidity
+ function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+```
+1)First - because the storage variable owner and the variable in the function is also called owner - the check that msg.sender == owner does not work, because owner is taken from the function parameters.
+
+2)The owner from storage does not change, as owner = owner just writes owner to the function variable.
+

+
+Broken change owner functionality
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+There is no attack path as such, it's just that the function is so broken that it doesn't do anything at all, even though it should change the owner
+
+### Impact
+
+There are two consequences to this error.
+1) The functionality is incorrectly implemented
+2) If it had been implemented correctly, anyone could pass the changeOwner check

+# Change Owner function doesnt check sequencer uptime feed
+
+### Summary
+
+Let's look at the [implementation](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682) of the changeOwner function in `Aggregator`, `AuctionFactory`, `BuyOrderFactory`

+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+
+We can see that the owner can only be changed within the first 6 hours of the contract being deposited. However, on L2 networks on which the protocol will be deployed - for example Arbitrum sequencer can fail and not work for several hours (there were cases when sequencer did not work for 10 hours on Arbitrum).
+
+Thus, if the sequencer fails within the first 6 hours, it will not be possible to change the owner if necessary.
+
+### Root Cause
+
+Change owner function relies on time, but does not take into account that the sequencer may fail
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+1. It becomes necessary to change the owner in the first 6 hours of deployment.
+
+2. Sequencer fails and stops processing transactions. In the worst case scenario, it may crash for > 6 hours and then the functionality will not be available at all.
+
+### Attack Path
+
+No special attack path
+
+### Impact
+
+I think this issue deserves medium severity.
+
+The protocol relies on a short period of time in L2 networks and does not take into account that the sequencer may go down. The probability is low, but the impact is high
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Add check sequencer status. And if it crashes - give the option to change the owner to bypass the time when sequencer was not processing transactions.
+
+Alternatively, make the refresh period longer - 6 hours is very short for L2 networks where the sequencer can fail for longer.

+# veNFTs kept as collateral might be lost forever if `safeTransferFrom` is not implemented in the protocol
+
+### Summary
+
+Not using the `safeTransferFrom` when transferring `ERC721` veNFTs might cause the veNFT to be lost forever if the receiver cannot handle `ERC721` tokens.
+
+### Root Cause
+
+There are 2 possible situations with the same root cause:
+1. If a borrower keeps their veNFT as collateral and fails to pay off the loan, the lender reserves the right to take the [collateral](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L403). The protocol uses the `transferFrom` function instead of the `safeTransferFrom` function to transfer the veNFT collateral from the Loan contract to the lender's address.
+2. If an veNFT enters an auction and a buyer is interested to buy the veNFT, the veNFT has a possibility of being lost [forever](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L149).
+
+The `transferFrom` function does not check if the recipient can handle the ERC721 tokens. If the lender can not handle the ERC721 tokens, the veNFT will be lost forever.
+
+On the other hand the `safeTransferFrom` function includes additional checks to ensure that the recipient can accept ERC721 tokens.
+
+### Internal pre-conditions
+
+### Scenario 1
+1. Borrower creates a borrow order with an veNFT as collateral.
+2. Borrower gets paired with a lender that cannot accept veNFTs.
+3. Borrower does not pay the loan off.
+4. Lender tries to collect the collateral but never receives it.
+
+### Scenario 2
+1. A veNFT is held in auction.
+2. Buyer buys the veNFT.
+3. Buyer never receives the veNFT.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+This will impact the lenders who cannot accept `ERC721` tokens. This will lead to a **100%** loss of funds for the lender. They will lose all of the tokens they lent to the borrower, plus the collateral they tried to collect.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Please use OpenZeppelin's `safeTransferFrom` function to transfer `ERC721` tokens.

+# After calling `extendLoan` if Borrower miss the earliest deadline, they can not pay any debt and lender can claim collateral early
+
+### Summary
+
+The `nextDeadline` function in the `DebitaV3Loan.sol` contract has logic flaws that lead to two significant issues:
+
+1. After calling `extendLoan`, Borrowers cannot pay any debt if they miss earliest deadline, this would resulting default for all loans.
+2. Lenders can claim collateral before the deadline of specific extended loans, potentially claiming collateral early.
+
+### Root Cause
+
+The root cause of both issues is the logic in the `nextDeadline` after `extendLoan` is called, which always return the earliest unpaid loan's deadline:
+
+[DebitaV3Loan.sol#L743-L764](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L743-L764)
+
+```js
+ function nextDeadline() public view returns (uint) {
+ uint _nextDeadline;
+ LoanData memory m_loan = loanData;
+ if (m_loan.extended) {
+ for (uint i; i < m_loan._acceptedOffers.length; i++) {
+ if (
+ _nextDeadline == 0 &&
+ m_loan._acceptedOffers[i].paid == false
+ ) {
+@> _nextDeadline = m_loan._acceptedOffers[i].maxDeadline;
+ } else if (
+@> m_loan._acceptedOffers[i].paid == false &&
+@> _nextDeadline > m_loan._acceptedOffers[i].maxDeadline
+ ) {
+@> _nextDeadline = m_loan._acceptedOffers[i].maxDeadline;
+ }
+ }
+ } else {
+ _nextDeadline = m_loan.startedAt + m_loan.initialDuration;
+ }
+ return _nextDeadline;
+ }
+```
+
+This is problematic because if the Borrower missed the earliest deadline, there are no way in the logic contract to make the offer paid status to true except from the `payDebt` function.
+Regardless of the indexes provided as parameter when calling the function, the require line would always be false, preventing for the state of paid changed.
+[DebitaV3Loan.sol#L186-L205](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L186-L205)
+
+```js
+ function payDebt(uint[] memory indexes) public nonReentrant {
+ IOwnerships ownershipContract = IOwnerships(s_OwnershipContract);
+
+ require(
+ ownershipContract.ownerOf(loanData.borrowerID) == msg.sender,
+ "Not borrower"
+ );
+ // check next deadline
+@> require(
+@> nextDeadline() >= block.timestamp,
+@> "Deadline passed to pay Debt"
+ );
+
+ for (uint i; i < indexes.length; i++) {
+ uint index = indexes[i];
+ // get offer data on memory
+ infoOfOffers memory offer = loanData._acceptedOffers[index];
+
+ // change the offer to paid on storage
+@> loanData._acceptedOffers[index].paid = true;
+```
+
+If we take a look at `claimCollateralAsLender` the behavior of `nextDeadline` causing early collateral claim:
+
+[DebitaV3Loan.sol#L340-L355](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L340-L355)
+
+```js
+ function claimCollateralAsLender(uint index) external nonReentrant {
+ LoanData memory m_loan = loanData;
+ infoOfOffers memory offer = m_loan._acceptedOffers[index];
+ IOwnerships ownershipContract = IOwnerships(s_OwnershipContract);
+ require(
+ ownershipContract.ownerOf(offer.lenderID) == msg.sender,
+ "Not lender"
+ );
+ // burn ownership
+ ownershipContract.burn(offer.lenderID);
+@> uint _nextDeadline = nextDeadline();
+
+ require(offer.paid == false, "Already paid");
+ require(
+@> _nextDeadline < block.timestamp && _nextDeadline != 0,
+ "Deadline not passed"
+```
+
+as stated before, the value of `_nextDeadline` would be the earliest deadline of all the loan inside the contracts.
+after calling `extendLoan`, the require value would be true if the borrower missing earliest deadline, making the lender of later max deadline can claim borrower collateral early.
+
+### Internal pre-conditions
+
+1. example `timestamp = 0`
+2. Borrower got matching with offers `index = 0, 1, 2` with condition of:
+ - LoanData for the loan is `startedAt = 0` and `initialDuration = 10 days`
+ - `maxDeadline` for each offer index respectively `initialDuration` increased by `10, 20, 30`
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+Case 1, Borrower cant pay debt:
+
+1. `timestamp = 1 days` (10% of initialDuration to be able to extend the loan)
+2. Borrower call `extendLoan`, now `nextDeadline` would return earliest `maxDeadline` which is `initialDuration + 10`
+3. `timestamp = initialDuration + 11`
+4. Borrower missing deadline at timestamp `initialDuration + 10` / offer index 0
+5. Borrower call `PayDebt` with index [1,2] which the maxDeadline is at `initialDuration + 20, initialDuration + 30`
+6. call fails because `nextDeadline() >= block.timestamp` would return `initialDuration + 10 >= initialDuration + 11` which is false
+7. Borrower cant pay any debt
+
+Case 2, Borrower collateral is claimed by Lender before the deadline expires:
+
+1. `timestamp = 1 days` (10% of initialDuration to be able to extend the loan)
+2. Borrower call `extendLoan`, now `nextDeadline` would return earliest `maxDeadline` which is `initialDuration + 10`
+3. `timestamp = initialDuration + 11`
+4. Borrower missing deadline at timestamp `initialDuration + 10` / offer index 0
+5. Lender (owner of offer index 2) call `claimCollateralAsLender` with index 2
+6. Call succeed because the require `_nextDeadline < block.timestamp && _nextDeadline != 0` would return `initialDuration + 10 < initialDuration + 11 && initialDuration + 10 !=0` which is true
+7. Lender claimed Borrower collateral that tied with offer index 2 `timestamp = initialDuration + 11` even though the deadline for offer index 2 is `initialDuration + 30`
+
+### Impact
+
+1. Borrower will always face default for all loan if after `extendLoan` they missed the earliest deadline
+2. Lenders (owner of offer) also can claim any of the Borrower collateral if after `extendLoan` the Borrower missed the earliest deadline

+# No price feed update functional may result in a broken chainlinkOracle for the given token.
+
+### Summary
+
+Let's take a look at the [setPriceFeed](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L71) function in `ChainlinkOracle`.

+ function setPriceFeeds(address _token, address _priceFeed) public {
+ require(msg.sender == multiSig, "Only manager can set price feeds");
+ // only declare it once
+ require(priceFeeds[_token] == address(0), "Price feed already set");
+ priceFeeds[_token] = _priceFeed;
+ isFeedAvailable[_priceFeed] = true;
+ }
+```
+
+We can see that the function only allows the priceFeed to be set once. So there is no way to update it. So there is no way to update it. It is not very clear why these restrictions are necessary for the protocol, if the update is performed by a trusted party - multisig.

+### Root Cause
+
+A trusted multisig entity cannot change a price feed that has already been assigned.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+The previous price feed failed, but the protocol cannot migrate to the new implementation because the constraints are too strict.

+# Attacker will delete all active lend orders, causing a Denial of Service for all users
+
+### Summary
+
+In the smart contract `DebitaLendOffer-Implementation.sol`, the [cancelOffer()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L144) and [addFunds()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L162) functions do not check if the lend offer is active (isActive). It only validates if `availableAmount > 0`.
+
+This allows a malicious lend offer owner to repeatedly exploit the protocol. He can call `cancelOffer()` to remove his offer from the factory’s active orders list, then use `addFunds()` to add a small amount back to the canceled offer, making it appear valid again. They can then cancel the offer again to delete another offer in the factory list.
+By repeating this process, the attacker can systematically delete all lending offers in the lend offer factory.
+
+As a result, the attacker causes a Denial of Service (DoS) for other users, leaving the protocol with no active lend orders.
+
+### Root Cause
+
+In `DebitaLendOffer-Implementation.sol`, the [cancelOffer()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L144) and [addFunds()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L162) do not check if the offer isActive
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. **Preparation:**
+ • The attacker calls `createLendOrder()` in `DebitaLendOfferFactory.sol` to create a lend offer and ensures it has a valid availableAmount. We’ll call it **_AttackerOrder_**
+ • The _AttackerOrder_ is added to the factory’s active orders list.
+2. **Removing the order:**
+ • The attacker calls `cancelOffer()` on _AttackerOrder_.
+ • This marks _AttackerOrder_ as inactive and removes it from the factory’s active orders list by calling the deleteOrder() function (LendOrderIndex[_lendOrder] = 0).
+3. **Reactivating the order:**
+ • The attacker calls `addFunds(1 wei)` on _AttackerOrder_.
+ • This function does not validate if the lend offer is active (isActive).
+ • Adding a small amount of funds makes _AttackerOrder_ `appear valid` again. (`availableAmount += amount;`)
+4. **First exploit: Removing Another order:**
+ • The attacker calls cancelOffer() again on _AttackerOrder_.
+ • The function does not check that the lend offer is not active (isActive). It only checks if availableAmount > 0.
+ • It calls deleteOrder() from factory to remove the _AttackerOrder_.:
+ `IDLOFactory(factoryContract).deleteOrder(address(this))`
+ • [`deleteOrder()` ](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L205-L220) changes the index of the last order to the index of _AttackerOrder_. Since the index of _AttackerOrder_ was set to zero in step two, the index of the last order also becomes zero, meaning it gets deleted from the list as well.
+ • The vulnerability allows this operation to remove another unrelated order from the factory’s active orders list.
+5. **Repeat:**
+ • The attacker repeats steps 3 and 4.
+ • With each iteration, another order is removed from the factory’s active orders list.
+6. **Final Outcome:**
+ • The attacker continues this process until all active lend orders in the factory are deleted.
+
+### Impact
+
+The protocol is left with no active lend orders, causing a Denial of Service (DoS) for all legitimate users.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+add this check to `cancelOffer()` and `addFunds()` functions in `DebitaLendOffer-Implementation.sol`:
+`require(isActive, "Offer is not active");`

+# `DebitaPyth::getThePrice` incorrectly integrates getPriceNoOlderThan
+
+### Summary
+
+[Pyth documentation](https://docs.pyth.network/price-feeds/use-real-time-data/evm) directly says to call updatePriceFeeds before calling getPriceNoOlderThan.
+```solidity
+// Submit a priceUpdate to the Pyth contract to update the on-chain price.
+ // Updating the price requires paying the fee returned by getUpdateFee.
+ // WARNING: These lines are required to ensure the getPriceNoOlderThan call below succeeds. If you remove them, transactions may fail with "0x19abf40e" error.
+ uint fee = pyth.getUpdateFee(priceUpdate);
+ pyth.updatePriceFeeds{ value: fee }(priceUpdate);
+```
+Otherwise the transaction may crash with 0x19abf40e error. The protocol does not catch this error when calling [getPriceNoOlderThan](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L25), although it does not call updatePriceFeeds. Thus, the function may terminate with revert and become a point of failure for all other protocol functions calling it.
+
+```solidity
+function getThePrice(address tokenAddress) public view returns (int) {
+ // falta hacer un chequeo para las l2
+ bytes32 _priceFeed = priceIdPerToken[tokenAddress];
+ require(_priceFeed != bytes32(0), "Price feed not set");
+ require(!isPaused, "Contract is paused");
+
+ // Get the price from the pyth contract, no older than 90 seconds
+ PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ _priceFeed,

+ );
+
+ // Check if the price feed is available and the price is valid
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+ require(priceData.price > 0, "Invalid price");
+ return priceData.price;
+ }
+```
+### Root Cause
+
+The protocol does not call updatePriceFeeds before calling getPriceNoOlderThan, which allows for the possibility that the call will end with revert due to error 0x19abf40e.
+
+However, the protocol does not catch this error either.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+The price has not been updated for the specified time (for this function it is 600 seconds). In this case - the call will end with revert
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+Incorrect integration can create a single point of failure. The protocol simply stops supporting all calls that cause to this price feed, so matchOffers in the Aggregator will not work for all offers that use pyth oracle for this token.

+# Protocol ignores confidence intervals when integrating pyth oracle
+
+### Summary
+
+The prices fetched by the Pyth network come with a degree of uncertainty which is expressed as a confidence interval around the given price values. Considering a provided price `p`, its confidence interval `σ` is roughly the standard deviation of the price's probability distribution. The [official documentation of the Pyth Price Feeds](https://docs.pyth.network/documentation/pythnet-price-feeds/best-practices#confidence-intervals) recommends some ways in which this confidence interval can be utilized for enhanced security. For example, the protocol can compute the value `σ / p` to decide the level of the price's uncertainty and disallow user interaction with the system in case this value exceeds some threshold.
+
+Currently, the protocol [ignores](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L25) the confidence interval provided by the price feed. Consider utilizing the confidence interval provided by the Pyth price feed as recommended in the official documentation. This would help mitigate the possibility of users taking advantage of invalid prices.

+# Attacker can Frontrun the `buyNFT` function to pay less money for `veTokens` that are Auctioned
+
+### Summary
+
+The `buyNFT` function can be frontrun by attackers when `veNFTs` are being auctioned off. Since these tokens are the governance tokens of the protocol, attackers might be more motivated to gain access to the tokens.
+
+A HIGH severity is considered for this vulnerability because these are the Governance Tokens of the protocol that are being auctioned off.
+
+### Root Cause
+
+In a Dutch Auction, the price decreases steadily until somebody pays the price they feel is worth the item in the auction.
+
+In this protocol, veNFTs can be auctioned off to prospective buyers, either by their own accord or to liquidate a failed loan's collateral. The problem with the Auction in this protocol is that attackers can always frontrun the [`buyNFT`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109) function.
+
+An attacker will see that the veNFT is valuable, but they don't want to pay the full price for the veNFT. They will wait till an honest user calls the function to buy the veNFT, after which they will front-run the transaction and buy the veNFT for the lowest price possible in that auction (as compared to the original time/price the attacker wanted to buy the veNFT). The attacker would do this to pay less money, and sell the NFT at a later date for more profit.

+
+### Impact
+
+Every single auction in the protocol can be frontrun which can cause a lot of economic damages to the protocol, as well as reputation damage if the buy function of the auction never works.
+
+Additionally, it is to be noted that the veNFTs which are sold in the auction are the governance tokens of the protocol. Attackers will definitely be interested to buy up all available veNFTs if they aim to get more voting power.

+# TaxTokenReceipt does not support fee on transfer tokens as it supposed to do
+
+### Summary
+
+Let’s consider the function [`TaxTokensReceipts::deposit'](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L59)

+ msg.sender,
+ address(this),
+ amount
+ );
+ uint balanceAfter = ERC20(tokenAddress).balanceOf(address(this));
+ uint difference = balanceAfter - balanceBefore;

+ return tokenID;
+ }
+```
+
+```solidity
+uint difference = balanceAfter - balanceBefore;
+require(difference >= amount, "TaxTokensReceipts: deposit failed");
+```
+According to the README of the content this function should support FOT tokens. However, as you can see, it does not support because the check will never be true for FOT tokens.
+
+The difference can never be more than the sent amount. It can only be equal - but not in case of token FOT.
+
+Thus, this contract supports only regular tokens, and any deposit FOT token will be revert.
+
+
+### Root Cause
+
+The difference can never be more than amount - sent to contract.
+
+For FOT tokens it will always be smaller.

+# The changeOwner() function will not change the contract owner
+
+### Summary
+
+in `AuctionFactory.sol` , `buyOrderFactory.sol` , `DebitaV3Aggregator.sol` :
+The changeOwner function is intended to change the ownership of a contract. However, it does not update the state variable owner as expected. This issue occurs because the local parameter owner has the same name as the state variable owner. In Solidity, the local parameter takes precedence within the function scope, causing the statement owner = owner to assign the local owner to itself, without affecting the state variable.
+
+### Root Cause
+
+In [DebitaV3Aggregator.sol:682](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682-L686) `owner = owner` does not changee the owner of contract:

+# `IERC20(token).approve` will revert if the principle ERC20 token approve does not return boolean value
+
+## Summary
+
+## Vulnerability Detail
+
+In `DebitaV3Loan` when transferring the token, the contract uses `safeTransfer` and `safeTransferFrom` but when approving the principle token in `payDebt() and extendLoan()`, the safeApprove is not used for non-standard token such as USDT, which will make the `approve()` to revert because it doesn't return boolean. This can lead borrowers not being able to pay their debt or extend their loan which will make them subject of liquidation and then lose their collateral.
+
+## Impact
+
+USDT or other ERC20 token that does not return boolean for approve will revert the transaction.
+

+# TaxTokenReceipt saves amount in tokenAmountPerID instead of received difference
+
+### Summary
+
+Let’s consider the function [`TaxTokensReceipts::deposit'](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L59)
+```solidity
+function deposit(uint amount) public nonReentrant returns (uint) {
+ uint balanceBefore = ERC20(tokenAddress).balanceOf(address(this));
+ SafeERC20.safeTransferFrom(
+ ERC20(tokenAddress),
+ msg.sender,
+ address(this),
+ amount
+ );
+ uint balanceAfter = ERC20(tokenAddress).balanceOf(address(this));
+ uint difference = balanceAfter - balanceBefore;
+ require(difference >= amount, "TaxTokensReceipts: deposit failed");
+ tokenID++;
+ tokenAmountPerID[tokenID] = amount;
+ _mint(msg.sender, tokenID);
+ emit Deposited(msg.sender, amount);
+ return tokenID;
+ }
+```
+We see that the tokenAmountPerID for tokenId is saved as amount - the number sent by the token user.
+
+However, as stated in README - this contract supports FOT tokens. So in these cases amount can be more than the received value.
+
+Further, when the funds are withdrawn, the user receives exactly amount and cannot withdraw less, although amount may not be kept on contract.
+Thus, the user’s output is blocked. And in general the money flow of the whole protocol is disrupted.
+
+```solidity
+function withdraw(uint _tokenID) public nonReentrant {
+ require(
+ ownerOf(_tokenID) == msg.sender,
+ "TaxTokensReceipts: not owner"
+ );
+ uint amount = tokenAmountPerID[_tokenID];
+ tokenAmountPerID[_tokenID] = 0;
+ _burn(_tokenID);
+
+ SafeERC20.safeTransfer(ERC20(tokenAddress), msg.sender, amount);
+ emit Withdrawn(msg.sender, amount);
+ }
+```
+### Root Cause
+
+The user’s tokenAmountPerId is written as amount instead of difference.
+
+### Internal pre-conditions
+
+### External pre-conditions
+
+The user contributes funds to the contract. and then tries to take them away.
+There may be a situation where he cannot pick up because the contract does not have enough funds to withdraw.
+
+### Attack Path
+
+### Impact
+The mechanism is blocked and the FOT support is broken.
+Severity: Medium
+### PoC
+
+### Mitigation
+
+Save difference instead amount

+# Borrower can not `extendLoan` if the `maxDuration` is under 5 days due to underflow
+
+### Summary
+
+If the loan data `maxDuration` is less than `5 days` the logic of `DebitaV3Loan::extendLoan` would underflow when calculating `misingBorrowFee`.
+
+
+### Root Cause
+
+If we look at the instance where `missingBorrowFee` are calculated inside `extendLoan`, there are 2 crucial variable `feeOfMaxDeadline` and `PorcentageOfFeePaid`.
+
+for `PorcentageOfFeePaid` the calculation is:
+
+[DebitaV3Loan.sol#L575-L579](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L575-L579)
+
+```js
+if (PorcentageOfFeePaid > maxFee) {
+ PorcentageOfFeePaid = maxFee;
+} else if (PorcentageOfFeePaid < minFEE) {
+ PorcentageOfFeePaid = minFEE;
+}
+```
+
+where `PorcentageOfFeePaid` value would be between `minFEE` or `maxFee` which is between range of `20 to 80`.
+
+for `feeOfMaxDeadline`:
+
+[DebitaV3Loan.sol#L600-L611](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L600-L611)
+
+```js
+ if (PorcentageOfFeePaid != maxFee) {
+ // calculate difference from fee paid for the initialDuration vs the extra fee they should pay because of the extras days of extending the loan. MAXFEE shouldnt be higher than extra fee + PorcentageOfFeePaid
+@> uint feeOfMaxDeadline = ((offer.maxDeadline * feePerDay) /
+ 86400);
+ if (feeOfMaxDeadline > maxFee) {
+ feeOfMaxDeadline = maxFee;
+ } else if (feeOfMaxDeadline < feePerDay) {
+ feeOfMaxDeadline = feePerDay;
+ }
+
+@> misingBorrowFee = feeOfMaxDeadline - PorcentageOfFeePaid;
+ }
+```
+
+`feeOfMaxDeadline` should be expected to be greater than or equal to `PorcentageOfFeePaid`, but there are times when this line underflow.
+by the calculation above we should note that `feeOfMaxDeadline` can be as low as `feePerDay` which is `4`, this can happen if the `offer.maxDeadline` equal to `1 days`.
+
+the overflow would happen as long as `feeOfMaxDeadline` is less than `20`, this can be achieved when `offer.maxDeadline` at `5 days -1` or less.
+
+### Internal pre-conditions
+
+1. lender create lend offer where the `maxDeadline` at `5 days -1`
+2. borrower create borrow offer
+3. match offer
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. after 10% of duration, borrower call `extendLoan`
+2. calls revert
+
+### Impact
+
+Borrower can not extend their loan

+### Mitigation
+

+# User Can Stockpile Most Incentives Due to Lack of Control in Loan Parameters
+
+### Summary
+
+A user can exploit the system to claim most of incentives by being both the borrower and lender of the same loan. The protocol currently does not restrict this behavior. While the downside of being both parties is the loss of protocol fees, the exploit can still be profitable under certain conditions.
+
+There are two types of fees imposed by the protocol:
+1. **Matching Offers Fee:** For each amount of principal lent, the protocol charges a fee ranging from **0.2% to 0.8%**.
+2. **Repayment Fee:** When repaying the debt, the protocol charges **15% of the accrued interest**.
+
+
+If a user minimizes the fees, they can profit from double rewards while stockpiling most of the incentives pool for a given pair of tokens.
+
+**How we can avoid the fees?**
+1. **Avoiding the lender fee (15%)**:
+- Set an APR of 0% for both borrower and lender sides.
+- This is permitted by the protocol, as the condition in [`DebitaV3Aggregator:560`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L560) only checks that `weightedAPR` is ≤ `maxAPR`, which is satisfied when both are 0%.
+
+2. **Minimizing borrower fees**:
+- Use a very short loan duration, resulting in a minimum fee of 0.2%.
+- There are no controls on duration parameters, which allows setting a minimum duration without constraints.
+
+
+The attacker incurs only a **0.2% loss of the principle amount in fees**, making the profitability of this attack reliant on the incentives offered for the token pair. If the incentives exceed **0.2% of the principle amount**, the attacker can profit and repeatedly exploit this to drain all available incentives for the token pair. Even with a minimal profit margin, this approach can still serve to **grief** other eligible users by monopolizing the incentives, disrupting fair distribution.
+
+### Root Cause
+
+- The protocol does not enforce a **minimum APR**. This allows setting the APR to 0%, effectively bypassing lender fees.
+- The absence of a **minimum loan duration**. Without this, controlling APR becomes meaningless, as users can create loans with extremely short durations (e.g., 1 minute) and repay immediately, resulting in negligible fees even with a high APR.
+
+### Internal pre-conditions
+The incentive rewards per amount of principle used must be greater or equal than 0.2% of the same principle amount.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+User incentivizes lending and borrowing actions when using USDC:
+
+- **Principle**: [USDC, USDC]
+- **Mode**: [lend, borrow]
+- **Rewards amount**: [1000, 1000] DAI
+- **Epoch**: [5, 5]
+
+#### Data incentives:
+- `LentIncentivesPerTokenPerEpoch[USDC][DAI, 5]`: 1000
+- `BorrowIncentivesPerTokenPerEpoch[USDC][DAI, 5]`: 1000
+- `TotalUsedTokenPerEpoch[USDC][5]`: 0
+
+#### During Epoch 5:
+People begin creating loans using USDC to receive rewards:
+- `TotalUsedTokenPerEpoch[USDC][5]`: 50,000
+
+Bob creates a **borrow order** and a **lend order** to match together:
+- **Borrow Offer**:
+ - `MaxAPR`: 0%
+ - `Duration`: 1 day
+ - `Accepted principle`: USDC
+ - `Collateral amount`: 1 WBTC
+- **Lend Offer**:
+ - `APR`: 0%
+ - `Max duration`: 3 days
+ - `Min duration`: 1 day
+ - `Accepted collateral`: WBTC
+ - `Principle amount`: 40,000 USDC
+
+### Matching the offer:
+- `APR`: 0%
+- `Duration`: 1 day
+- **Protocol fee**: 80 USDC (0.2%)
+- **Amount lent**: 40,000 USDC
+
+---
+
+### First iteration:
+**Update funds incentives**:
+- `LentAmountPerUserPerEpoch[Bob][USDC, 5]`: 40,000
+- `TotalUsedPerTokenPerEpoch[USDC][5]`: 40,000 + 50,000 = 90,000
+- `BorrowAmountPerEpoch[Bob][USDC, 5]`: 40,000
+
+**Repay debt and accounting**:
+- Bob's WBTC balance: 1 WBTC
+- Bob's USDC balance: 39,920 USDC
+- **Percentage Lent**: 44% (`LentAmountPerUserPerEpoch / TotalUsedPerTokenPerEpoch`)
+- **Percentage Borrow**: 44% (`BorrowAmountPerEpoch / TotalUsedPerTokenPerEpoch`)
+- **Amount to claim on lending**: 444 DAI (`1000 * Percentage Lent`)
+- **Amount to claim on borrowing**: 444 DAI (`1000 * Percentage Borrow`)
+- **Fee taken**: 80 USDC
+- **Net value**: 888 DAI - 80 = 808 DAI
+- **Percentage of loss**: 80 / 888 ≈ 9%
+
+---
+
+### Second iteration:
+**Update funds incentives**:
+- `LentAmountPerUserPerEpoch[Bob][USDC, 5]`: 80,000
+- `TotalUsedPerTokenPerEpoch[USDC][5]`: 40,000 + 90,000 = 130,000
+- `BorrowAmountPerEpoch[Bob][USDC, 5]`: 80,000
+
+**Repay debt and accounting**:
+- Bob's WBTC balance: 1 WBTC
+- Bob's USDC balance: 39,840 USDC
+- **Percentage Lent**: 61% (`LentAmountPerUserPerEpoch / TotalUsedPerTokenPerEpoch`)
+- **Percentage Borrow**: 61% (`BorrowAmountPerEpoch / TotalUsedPerTokenPerEpoch`)
+- **Amount to claim on lending**: 615 DAI (`1000 * Percentage Lent`)
+- **Amount to claim on borrowing**: 615 DAI (`1000 * Percentage Borrow`)
+- **Fee taken**: 160 USDC
+- **Net value**: 1230 DAI - 160 = 1070 DAI
+- **Percentage of loss**: 160 / 1230 ≈ 13%
+
+---
+
+
+**NOTE**: The more iterations you repeat, the greater your percentage of rewards. However, you also incur higher protocol fees. It is crucial to calculate the **optimal point of benefit** where we can maximize the profit.
+
+### Impact
+
+- A user can act accumulate and profit from most of the incentives allocated for a specific pair of tokens.
+- A user can reduce the incentive distribution to legitimate users eligible for the same token pair, effectively griefing them.
+- The user can manipulate the system to claim a disproportionate share of incentives, exceeding what they would receive under normal participation rules.

+
+
+
+
+### Mitigation
+
+By enforcing both a **minimum APR** and a **minimum loan duration**, the attacker would be required to pay more fees. This would disincentivize the exploit, as the costs would mostly outweigh the potential gains from the incentives.

+# Possible `DoS` at `claimBribesMultiple`
+
+## Summary
+
+When performing a function `claimBribesMultiple`, this function has three nested looping that possible to DoS block gas limit.
+
+## Vulnerability details
+
+At the function `claimBribesMultiple`, there is a lot of looping, possible to cause a block gas limit. There are three looping associated. First looping at :
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/veNFTS/Aerodrome/Receipt-veNFT.sol#L128-L142
+
+Afterthat, second looping and third at :
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/veNFTS/Aerodrome/veNFTAerodrome.sol#L151-L172
+
+In this code also perfoming transfer token that use a lot of gas cost. Assume (worst case) that transfer token and smart contract interaction use `100,000` gas units. We know that max block gas limit is `30 milion` gas units. So, the max interaction is `30_000_000` / `100_000` = `300` iterations. If we perform with three nested loop `(n**3)`, the possible maximum `n` is `7(7**3 = 343)`. In conclusion, we only can use length of each array `address[] calldata vaults, address[] calldata _bribes, address[][] calldata _tokens` not more than `7`.
+
+## Recomendation
+
+To avoid this issue, please add more input validation for array length to avoid block gas limit.

+# `BuyOrder` is not compliant with `TaxTokenReceipt`
+
+### Summary
+
+When a user call the [`BuyOrder::sellNFT`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L92-L142) function, he will encounter the following block of code:
+```javascript
+ IERC721(buyInformation.wantedToken).transferFrom(
+ msg.sender,
+ address(this),
+ receiptID
+ );
+```
+If the `buyInformation.wantedToken` address is a `TaxTokenReceipt` NFT, the transfer will always revert due to the checks performed in the `TaxTokenReceipt::transferFrom` function:
+```javascript
+ function transferFrom(
+ address from,
+ address to,
+ uint256 tokenId
+ ) public virtual override(ERC721, IERC721) {
+ bool isReceiverAddressDebita = IBorrowOrderFactory(borrowOrderFactory)
+ .isBorrowOrderLegit(to) ||
+ ILendOrderFactory(lendOrderFactory).isLendOrderLegit(to) ||
+ IAggregator(Aggregator).isSenderALoan(to);
+ bool isSenderAddressDebita = IBorrowOrderFactory(borrowOrderFactory)
+ .isBorrowOrderLegit(from) ||
+ ILendOrderFactory(lendOrderFactory).isLendOrderLegit(from) ||
+ IAggregator(Aggregator).isSenderALoan(from);
+ // Debita not involved --> revert
+ require(
+ isReceiverAddressDebita || isSenderAddressDebita,
+ "TaxTokensReceipts: Debita not involved"
+ );
+```
+As seen here, if the `to` or `from` addresses are not `BorrowOrder`, `LendOrder` or a `Loan`, the transaction will revet. This is the case with calling the `sellNFT` function as well. Since the borrow offer doesn't have the possibility to call the `sellNFT` function, there is no way for the transaction to go through, making the whole `BuyOrderFactory => BuyOrder` functionality completely unusable with `TaxTokenReceipt` NFT.
+
+### Root Cause
+
+Absence of check if the `to` or `from` address are part of the `Debita` contracts
+
+### Internal pre-conditions
+
+`TaxTokenReceipt` NFT being wanted from the buyer
+
+### External pre-conditions
+
+None
+
+### Attack Path
+
+None
+
+### Impact
+
+The `BuyOrderFactory => BuyOrder` functionality is not compliant with `TaxTokenReceipt` NFT.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+add a check in the `TaxTokenReceip::transferFrom` function to ensure that if the `to` or `from` addresses are part of the `Debita` system (Because they are and otherwise the transfer will always revert).

+# A malicious borrower can reclaim their collateral by calling the `DebitaBorrowOffer-Implementation::cancelOffer` function amidst an active loan
+
+## Impact
+### Summary
+The `DebitaBorrowOffer-Implementation::cancelOffer` function allows a borrower to cancel a borrow offer that they created earlier on. When a borrower calls the `DebitaBorrowOffer-Implementation::cancelOffer` function, their remaining collateral is transferred back to them excluding any fees they may have paid for the services they used.
+
+However, the protocol does not check if the caller has any active loans and sends the balance of their collateral to them without checking. Thus, a borrower can reclaim thier collateral without repaying their debt.
+
+### Vulnerability Details
+This vulnerability exists because the `DebitaBorrowOffer-Implementation::cancelOffer` function does not check if the borrow order about to be cancelled has been issued any loans or not. This means that irrespective of whether a borrow order has received any loan amounts or not, it can be canceled and the borrower's collateral returned to them.
+
+Here is a github link to the function in question https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L188-L218 and can be view in the snippet below
+
+```javascript
+ function cancelOffer() public onlyOwner nonReentrant {
+ BorrowInfo memory m_borrowInformation = getBorrowInfo();
+ uint availableAmount = m_borrowInformation.availableAmount;
+ require(availableAmount > 0, "No available amount");
+ // set available amount to 0
+ // set isActive to false
+ borrowInformation.availableAmount = 0;
+ isActive = false;
+
+
+ // transfer collateral back to owner
+ if (m_borrowInformation.isNFT) {
+ if (m_borrowInformation.availableAmount > 0) {
+ IERC721(m_borrowInformation.collateral).transferFrom(
+ address(this),
+ msg.sender,
+ m_borrowInformation.receiptID
+ );
+ }
+ } else {
+ SafeERC20.safeTransfer(
+ IERC20(m_borrowInformation.collateral),
+ msg.sender,
+ availableAmount
+ );
+ }
+
+
+ // emit canceled event on factory
+
+
+ IDBOFactory(factoryContract).deleteBorrowOrder(address(this));
+ IDBOFactory(factoryContract).emitDelete(address(this));
+ }
+```
+
+
+### Impact
+A borrower can call the `DebitaBorrowOffer-Implementation::cancelOffer` function after they have received a loan and reclaim their collateral without repaying their debt. This way, a malicious borrowr can steal from the protocol and all they loose is the transaction fees they paid. Thus, the lenders lose their funds which they made available on the protocol for lending.
+
+## Proof of Concept
+1. A malicious borrower sees that there are lendorders available on the protocol.
+2. The maalicious borrower creates a borrow order
+3. The malicious borrower then calls the `DebitaV3Aggregator::matchOffersV3` function so that they receive the loans they seek as specified in their borrow order
+4. The malicious borrower now calls the `DebitaBorrowOffer-Implementation::cancelOffer` function and reclaims their collateral without repaying the debt the owe from the loan they received. Thus the malicious borrower now have their collateral back and the asset they borrowed in their possession.
+5. Furthermore, we compare the malicious borrower and an honest borrower and see that the malicious borrower end up with more tokens than the honest borrower though they created a borrow order with same parameters. Thus demonstrating that malicious borrowers are rewarded more by the protocol than honest borrowers.
+
+Function for creating attacker loans

+
+
+## Tools Used
+
+Manual Review and Foundry
+
+
+## Recommended Mitigation Steps
+
+Consider modifying the `DebitaBorrowOffer-Implementation::cancelOffer` function to check whether a borrow order has received any loans and revert accordingly. The `DebitaBorrowOffer-Implementation::cancelOffer` function should only be callable if the borrow order has not been matched against other loan orders. This way, a borrow must repay their loans or have their collaterals siezed by the protocol.

+# Unauthorized initialization of `DBOImplementation` contract
+
+### Summary
+
+The `DBOImplementation` contract allows any user to call the `initialize()` function and set themselves as the owner, bypassing the intended initialization process via the `DBOFactory`. This vulnerability arises because the implementation contract is deployed without locking the `initialize()` function, leaving it exposed to malicious actors.
+
+### Root Cause
+
+The root cause of this vulnerability is the absence of a mechanism to lock the `initialize()` function in the implementation contract. Since `DBOImplementation` is deployed before `DBOFactory`, the `initialize()` function is callable by any user until a proxy uses it. This allows a malicious actor to:
+
+1. Deploy the `DBOImplementation` contract.
+
+2. Call `initialize()` directly, setting themselves as the owner and initializing the contract.
+
+3. Exploit ownership to manipulate the contract's state or assets.
+
+The lack of protection in the constructor to prevent direct initialization is the fundamental flaw.
+
+### Attack Path
+
+1. Deploy the `DBOImplementation` contract.
+
+2. Call the `initialize()` function directly with arbitrary parameters.
+
+3. Become the contract owner and gain full control over the contract.
+
+4. Exploit the contract by misusing its functionality or causing it to behave unpredictably.
+
+### Impact
+
+The impact of this vulnerability is severe:
+
+**Unauthorized Ownership**: Malicious actors can gain control of the `DBOImplementation` contract.
+
+**Asset Theft**: If assets are transferred to this contract before proper initialization, the attacker can steal them.
+
+**System Integrity**: The integrity of the `DBOFactory` and the entire borrowing/lending process is compromised as unauthorized contracts can be treated as legitimate.
+
+### Code Snippet
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L82
+
+### Tool used
+Manual Review
+
+### Mitigation
+
+To prevent this vulnerability, use the OpenZeppelin-provided `_disableInitializers()` function to lock the implementation contract upon deployment. This ensures the `initialize()` function cannot be called on the implementation contract itself.
+
+**Recommended Fix**
+
+Modify by adding the `DBOImplementation` constructor as follows:
+
+
+```solidity
+ constructor() {
+ _disableInitializers();
+}
+```
+
+
+This guarantees the `initialize()` function is only callable on proxies and not on the implementation contract directly.

+# Users can end up consuming stale Chainlink oracle price.
+
+### Summary
+
+The missing price staleness check in `getThePrice` function in `DebitaChainlink.sol` can cause the oracle price to end up using stale prices. This can lead to undesirable conditions e.g. bad debt.
+
+### Root Cause
+
+Missing price staleness check in `getThePrice` function in `DebitaChainlink.sol` (it only checks for Chainlink uptime feed, but not the oracle price itself). The code only uses `price` output from the `priceFeed.latestRoundData()`.
+
+See [code](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L42-L46)
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+- Oracle prices move very volatile
+- Chainlink price feed stops feeding (or get stuck) e.g. due to gas spikes or network congestion.
+
+### Attack Path
+
+1. Token price changes very volatile
+2. Attacker sees that the actual token price should already change, but the Chainlink oracle price has not updated yet for some reason.
+3. Attacker sees that attacker can collateralize token A and borrow out token B with value B > value A (possibly due to oracle prices being volatile and don't get updated).
+
+### Impact
+
+If Chainlink oracle is used in conjunction with other sources, then it may lead to price discrepancy (and may make tx revert if discrepancy is checked). If there's no check, then it's possible that the protocol ends up using the stale oracle price, which can lead to potential attack vectors e.g. attacker can lend and borrow using old oracle pries, which can actually create a bad debt in the system.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Check price staleness to a certain time interval e.g. 10 min.

+# lender will incur loss when the borrower repays too early
+
+### Summary
+
+there exists no min time limit for a borrower to repay the debt. if the borrower calls repay quickly after the loan is signed this may incur a loss of funds for the lender. the lender has to pay the following fee
+
+ uint feeToPay = (amountPerPrinciple[i] * percentage) / 10000;
+now consider a scenario
+
+Amount: 3000
+fee Percentage: 80 (0.80%)
+loan duration 4 months
+interest = 10%
+
+3000×80=240000
+240000÷10000=24
+
+
+For an amount of 3000 and a percentage of 80, the fee to pay is 24 units.
+
+
+
+the interest to pay on debt is calculated as
+
+ function calculateInterestToPay(uint index) public view returns (uint) {
+ infoOfOffers memory offer = loanData._acceptedOffers[index];
+ uint anualInterest = (offer.principleAmount * offer.apr) / 10000;
+ // check already duration
+ uint activeTime = block.timestamp - loanData.startedAt;
+ uint minimalDurationPayment = (loanData.initialDuration * 1000) / 10000;
+ uint maxDuration = offer.maxDeadline - loanData.startedAt;
+ if (activeTime > maxDuration) {
+ activeTime = maxDuration;
+ } else if (activeTime < minimalDurationPayment) {
+ activeTime = minimalDurationPayment;
+ }
+
+
+ uint interest = (anualInterest * activeTime) / 31536000;
+
+
+ // subtract already paid interest
+ return interest - offer.interestPaid;
+ }
+
+the borrower is subjected to pay a interest of minimal duration even if he repays early however this does not protect the lender from incurring a loss completely
+
+
+Parameters:
+
+Annual Interest (APR): 10%
+Loan Duration: 4 months
+Active Time: 10% of 4 months (calculated in seconds)
+10% of 4 months = 1,051,200 seconds (12 days)
+
+Interest for 12 days:
+uint anualInterest = (offer.principleAmount * offer.apr) / 10000;
+
+3000×1000=3000000
+3000000/10000 = 300
+annual interest = 300
+
+uint interest = (anualInterest * activeTime) / 31536000;
+uint interest = (300 * 1036800) / 31536000;
+uint interest = 311040000 / 31536000; = 9.86
+
+the calculated interest is = 9.86; which rounds to 9
+
+
+
+
+the protocol also charges a 15% fee on interest from the lender
+
+ uint public feeInterestLender = 1500; // 15% of the paid interest
+
+ uint feeOnInterest = (interest * feeLender) / 10000;
+
+So, the feeOnInterest 1.35 15%of interest amount
+
+ 9- 1 = 8
+
+
+total loss for the lender = 24 - 8 = 16
+
+which is more than 0.1% of 3000 this makes this issue valid as per sherlock rules

+
+### Attack Path
+
+the borrower will also pay the interest amount to the lender which makes this non profitable for the borrower however the borrower can still execute this for the following reasons
+
+1.If the borrower’s collateral has significantly appreciated in value, they may be incentivized to repay the loan early and take out a new loan based on the increased value of the collateral. This would allow the borrower to borrow more for the same amount of collateral, taking advantage of the new collateral value. In this case, the borrower is not incurring a significant penalty, and the lender faces a potential loss due to early repayment
+
+2.After reaching the minimal duration (10% of the loan duration), the borrower may no longer need the borrowed principal and may wish to repay early. However, the lender still faces the risk of not recovering the expected fees because the loan duration is shorter than anticipated.
+
+3.The borrower may find a better offer in the market and choose to repay early in order to take advantage of that new offer. This could happen if the borrower is able to repay without incurring significant penalties
+
+4.the borrower can select a loan duration that is longer than their actual needs, as long as it is within the maximum duration allowed by the lending offers. However, whether the borrower can repay the loan early Example: If the borrower needs a loan for 10 days but the lender allows a max loan duration of 30 days, the borrower could choose to borrow for the full 30 days

+# A borrower can still reclaim their collateral without repaying their debt after the debt repayment period has elasped
+
+## Impact
+### Summary
+Whenever a borrower receives a loan from the protocol, they are expected to repay the loan within the stipulated loan duration. Failure to repay any loan within the stipulated time amounts to forfeiture of the collateral by the borrower. The lender can then claim the collateral after the loan duration has elapsed with the borrower failing to repay their debt.
+
+However, a borrower can call the `DebitaBorrowOffer-Implementation::cancelOffer` function after the expiration of the loan repayment duration and still reclaim their collateral despite not repaying their loans. This leads to loss of funds on the part of lenders.
+
+### Vulnerability Details
+This vulnerability exists because the `DebitaBorrowOffer-Implementation::cancelOffer` function has no checks for whether the time to cancel an offer has passed or not. In essence, the `DebitaBorrowOffer-Implementation::cancelOffer` function can be called at all times in so far as it is called by a borrow who created a borrow order.
+
+Here is a github link to the function in question https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L188-L218 and can be view in the snippet below
+
+```javascript
+ function cancelOffer() public onlyOwner nonReentrant {
+ BorrowInfo memory m_borrowInformation = getBorrowInfo();
+ uint availableAmount = m_borrowInformation.availableAmount;
+ require(availableAmount > 0, "No available amount");
+ // set available amount to 0
+ // set isActive to false
+ borrowInformation.availableAmount = 0;
+ isActive = false;
+
+
+ // transfer collateral back to owner
+ if (m_borrowInformation.isNFT) {
+ if (m_borrowInformation.availableAmount > 0) {
+ IERC721(m_borrowInformation.collateral).transferFrom(
+ address(this),
+ msg.sender,
+ m_borrowInformation.receiptID
+ );
+ }
+ } else {
+ SafeERC20.safeTransfer(
+ IERC20(m_borrowInformation.collateral),
+ msg.sender,
+ availableAmount
+ );
+ }
+
+
+ // emit canceled event on factory
+
+
+ IDBOFactory(factoryContract).deleteBorrowOrder(address(this));
+ IDBOFactory(factoryContract).emitDelete(address(this));
+ }
+```
+
+### Impact
+
+Because the `DebitaBorrowOffer-Implementation::cancelOffer` function can be called at any time by the borrower, a borrower who sees that they have defaulted in repaying their loans and thier repayment time has elapsed will call the `DebitaBorrowOffer-Implementation::cancelOffer` function, exploring it as a back door to reclaim their collateral which legitimately has been forfeited by them by the virtue of defaulting in repaying their loans.
+
+Thus, the lenders are cheated and they end up loosing funds they borrowed to the borrower in the form of loan.
+
+## Proof of Concept
+1. A malicious borrower sees that there are lendorders available on the protocol.
+2. The maalicious borrower creates a borrow order
+3. The malicious borrower then calls the `DebitaV3Aggregator::matchOffersV3` function so that they receive the loans they seek as specified in their borrow order
+4. The malicious borrower fails to repay their loan on time and realizes that they have forfeited their collateral as a result. The borrow now calls the `DebitaBorrowOffer-Implementation::cancelOffer` function and reclaims their collateral without repaying the debt the owe.
+
+PoC
+ +We modify the `setUp` function in the `MultiplePrinciples.t.sol` so that the lend orders can fulfil more than one borrow offer in the following manner: + +```javascript +. +. +. +AEROContract.approve(address(DLOFactoryContract), 10e18);

+
+
+## Recommended Mitigation Steps
+
+Consider modifying the `DebitaBorrowOffer-Implementation::cancelOffer` function to prevent the function from being called at just any time. The `DebitaBorrowOffer-Implementation::cancelOffer` function should not be callable if the borrower has defaulted in paying their debt. This way, a borrow must repay their loans or have their collaterals siezed by the protocol.

+# Attacker can easly gain ownership over `AuctionFactory.sol` & `buyOrderFactory.sol`
+
+## Summary
+
+In `buyOrderFactory.sol` and `AuctionFactory.sol` there is a function called `changeOwner()` which should be callable only by the `owner address` of conract. It checks if `msg.sender == owner` and if no more than `6 hours ` have passed after the deployment of the contract, only then the tx will go through. The function accepts address variable named `owner` which shadows the extisting `owner` address declaration of the contract which leads to critical vulnerability.
+
+## Vulnerability Detail
+
+Because of the `owner` param shadowing , an attacker can easly change the ownership of `buyOrderFactory.sol` and `AuctionFactory.sol` . While the 6 hours after deployment didnt pass everyone can steal his ownership as well, so at the end he can use a MEV bot just before the `6 hours` to pass and gain ownership , after that no one will be able to rescue the factory contracts.
+
+In the first case in `buyOrderFactory.sol` by becoming the owner of the contract the attacker can only call `changeFee()` and change `sellFee` making it cheap or expensive ( from 0.2% to 1% max ) .
+
+In the second case in `AuctionFactory.sol` he will be able to call `setFloorPriceForLiquidations()`, `changeAuctionFee()`, `changePublicAuctionFee`, `setAggregator()`, `setFeeAddress()`. By having access over all of these important functions , like setting low or high fees, stealing fees by setting his own address for `feeAddress` or setting his own `aggegator address` he can manipulate the auction functionalities and make no incentives for the users to participate in the protocol.
+
+## Impact
+
+Attacker can easly get ownership over two core contracts and gain access over core functionalities which can change important values which are usable by the users interacting with the protocol and steal funds by setting his own address as `feeAddress`
+
+## Code Snippet
+
+[`AuctionFactory::changeOwner()`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L218-L222)
+
+```solidity
+ function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+```
+
+
+[`buyOrderFactory::changeOwner()`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L186-L190)
+
+```solidity
+ function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+```
+
+## PoC
+
+In Remix if you try to deploy the contract with `address1` and then try to call `changeOwner()` with setting new owner address the tx reverts, but if you try to call the function from `address2` by setting his address as the new owner for example the tx passes.
+
+```solidity
+// SPDX-License-Identifier: MIT
+pragma solidity ^0.8.0;

+ {
+ return owner;
+ }
+
+ function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ owner = owner;
+ }
+}
+```
+
+## Tool used

+# Incentives can be stolen by using flash loans to borrow huge amounts dominating the rewards pool
+
+### Summary
+
+`DebitaIncentives` presents a mechanism to motivate users to engage in Debita's ecosystem and/or specific pairs available. It's designed to fairly distribute rewards proportionally to the amount of principle from transactions the user was involved in with respect to the total principle flow per epoch. A malicious user would attempt to exploit this mechanism for financial gain by attempting to borrow funds and repay them instantly. This is limited by the market conditions and lender's unwillingness to be involved in scenarios where gained interest is limited. However, anyone can call `matchOffersV3()` so this is not a constraint. More importantly, debt can be repaid instantly, meaning that the attacker does not need to have huge capital and can utilize flash loans to dominate rewards calculations.
+
+### Root Cause
+
+Anyone can call `matchOffersV3()` with any orders - assuming they are complementary. At the same time, incentives are distributed **only** based on the amount borrowed/lent and a loan can be repaid instantly, rendering incentives mechanism useless for rewarding honest engagement.
+
+### Internal pre-conditions
+
+- an incentive has accumulated for a specific pair in a given epoch, either for borrow or loan it doesn't matter
+- the rewards $ value is larger than the borrow fee paid, considering the minimum fee is only 0.2% ( 0.17% as the connector fee goes back to them ) this condition is very likely to be met ( specific examples provided later on )
+
+### External pre-conditions
+
+--
+
+### Attack Path
+
+A malicious user uses a custom smart contract to create sufficiently large borrow and lend orders that match each other to dominate the incentive distribution using a flash loan to fund the operation - the debt repayment can be instant.
+
+The duration of the loan is 5 seconds to ensure minimum borrow fees AND avoid interest for `minimalDurationPayment` (although paying interest would just be a complication in calculations nothing more):
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L730-L734
+
+They call `matchOffersV3()` with their offers and instantly repay themselves to repay the flash loan provider in one tx.
+
+After the epoch ends they claim incentives dominating the rewards pool based on this calculation:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L200-L201
+
+### Impact
+
+All funds from `DebitaIncentives` can be stolen by creating fake engagements using flash loans.
+
+
+### PoC
+
+The test was created alongside the entire test file (except from a modified version of the `setUp()` function provided by the team). The most important part is the `AttackerContract` performing the flash loan transaction. Flash loans themselves are simplified to transfer funds to the attacker and back to avoid unnecessary complexity.

+```
+Detailed and descriptive comments are added for all essential steps.
+
+Scenario from the PoC explained in text:
+Let's assume there is $2000 worth of borrow incentives and the attacker wishes to spend a maximum $1000 on the borrow fee to grab 80% of the incentive pool - a net profit of $600. $1000 borrow fee is equivalent to a loan for almost $600,000 ( `1000 / (0.2% - connectorFee)` ). For this to be 80% of the total rewards, the total borrow amount for a given epoch had to be ($600,000/0.8 - $600,000 = $150,000) - which is reasonable, especially at the beginning where there are lots of incentives and the protocol is gaining traction. Note that the actual `flashLoanAmount` needs to be $1,200,000 because they need to create a borrow and lend order for $600,000 worth of collateral and principal respectively.
+
+### Mitigation
+
+The easiest way to significantly decrease the likelihood of this exploit is to make it impossible to create a loan and repay the debt in one transaction. This will make this attack very unlikely considering the required capital.

+# Debt repaying and liquidation mechanisms ignore the current token prices leading to loss of funds for lenders
+
+### Summary
+
+Current implementation of debt repaying and liquidation mechanisms in `DebitaV3Loan` does not account for principal and collateral tokens real-time dollar values. The protocol fails to handle volatile assets like wETH, wBTC or even AERO by assuming that their initial amount will have the same value during liquidation or debt repayment. Moreover, because live collateral token price checks are impossible there is no way to liquidate the loan before the deadline. These issues will lead to significant loss of funds for the lenders because depending on the price movement the borrowers might either decide to repay or get liquidated to avoid handling the bad debt.
+
+### Root Cause
+
+Early liquidation is impossible - due to a lack of price checks, putting the lender in a losing position when the collateral does not hold its value.
+
+The `total` amount to repay in `payDebt()` is calculated based solely on `principalAmount` which was supplied to the borrower (and interest with fees):
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L211-L213
+
+Similarly, all "claimCollateral" functions calculate transfer amounts using data exclusively from LoanData struct populated during loan creation in `matchOffersV3()`.
+
+Borrowers can easily end the loan by repayment, the lender cannot liquidate early.
+
+### Internal pre-conditions
+
+- there are loans which use any assets other than stablecoins as principle and/or collateral tokens
+
+
+### External pre-conditions
+
+- significant price movement occurs during loan's duration ( considering it's most likely on a multiple-day timeframe, it's inevitable )
+
+
+### Attack Path
+
+Malicious user *could* try to exploit predictable price movement for their own financial gain, but it's irrelevant as the loss of funds occurs even between honest actors as well.
+
+### Impact
+
+Significant loss of funds for both borrowers and lenders depending on the token price movement direction.
+
+Examples:
+
+Liquidation issue - lender's loss due to undercollateralization without liquidation:
+1. A loan is created where 1 wBTC ( at a price $100,000 ) is used as collateral in exchange for 100,000 USDC. The duration of the loan is 30 days. Assume 0 fees and 0% APR for simplicity.
+2. After 30 days the wBTC price has fallen to $80,000. The lender had no way to liquidate undercollateralized loan.
+3. Borrower does not repay the debt leaving with $20,000 worth of lender's USDC.
+
+Debt repayment issue - lender's loss due to repaying now overcollateralized loan with initial amounts:
+1. A loan created where 10,000 USDC is used as collateral in exchange for 4 ETH at a price of $2,500. The duration of the loan is 30 days. Assume 0 fees and 0% APR for simplicity.
+2. After 30 days ETH price falls to $2,000. The borrower has to pay off 4 ETH worth $8,000 to get 10,000 USDC at the cost of the lender.
+3. Borrower repays their debt receving 10,000 USDC back and leaving the lender with $8,000 worth of ETH.
+
+### PoC
+
+--
+
+### Mitigation
+
+When volatile assets are involved, ensure that the price movements of the collateral and principle tokens are tracked to calculate a health factor of the loan. Allow early liquidations in an event of undercollateralization and make sure debt is repaid with the amount of principle adjusted by the dollar value. The current implementation will not provide safe conditions for mid or long-term loans.

+# Contracts cannot be upgraded because the implementationContract address is fixed and cannot be modified.
+
+### Summary
+
+In the `buyOrderFactory.sol` contract (also in `DebitaLendOfferFactory.sol` and `DebitaBorrowOffer-Factory.sol`), the variable [implementationContract](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L52) stores the address of the implementation contract (logic) that the proxy will direct to. However, there is no function available to change this address later, preventing **upgrades** to a new version of the contract.
+
+The `createBuyOrder()` function deploys a `DebitaProxyContract`, a proxy which directs to the same address of `implementationContract` (does not get the address as input parameter and again the address is unchangable)
+
+Additionally, inside the DebitaProxyContract, there is no function to change the implementation address or upgrade the contract. The proxy library from OpenZeppelin, which is imported in it, is also not upgradable.
+
+### Root Cause
+
+In DebitaBorrowOffer-Factory.sol, buyOrderFactory.sol, DebitaLendOfferFactory.sol contracts
+there is no mechanism to change the address of `implementationContract` and upgrade the contract
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions

+
+### Attack Path
+
+1. Deploy the buyOrderFactory.sol contract.
+2. Create a buy order using the createBuyOrder() function.
+3. Observe that the deployed DebitaProxyContract points to the implementationContract.
+4. Notice that there is no method available to change the address of implementationContract or upgrade the proxy contract to a new implementation.
+
+### Impact

+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Three different solutions:
+1. Add a function to the mentioned contracts to allow upgrading (changing the implementationContract address).
+2. Ensure that the proxy contract allows changing the implementation address.
+3. If using OpenZeppelin’s proxy, consider using an upgradable proxy such as TransparentUpgradeableProxy or UUPSProxy.

+# The `createBuyOrder()` function lacks the necessary parameters to properly buy a veNFT
+
+### Summary
+
+In the [`buyOrderFactory::createBuyOrder`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L75) function, users can create an order to buy a specific type of NFT (e.g., veAERO or veEQUAL). Once the order is created, owners of these NFTs can [sell them](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L92) through the `buyOrder` instance that has been created.
+
+
+The issue arises during the selling process. The function only considers the [amount locked](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L108) in the NFT, ignoring the [lock duration](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/veNFTS/Aerodrome/Receipt-veNFT.sol#L30).
+
+This oversight is significant, as a user could receive two veNFTs with the same locked amount but drastically different lock durations (e.g., one locked for 1 week and another locked for 4 years) while paying the same price. Accounting for lock duration is crucial to ensure fair valuation in the `buyOrder` process.

+Lack of lock duration params in `createBuyOrder` function.

+### Attack Path
+
+Alice owns a veAERO:
+- Locked amount: 10,000 AERO
+- Locked duration: 1 year
+- Voting power: 2,500 AERO
+
+Bob owns another veAERO:
+- Locked amount: 10,000 AERO
+- Locked duration: 4 years
+- Voting power: 10,000 AERO
+
+John creates a buy order to purchase a veAERO:
+- Available amount: 10,000 AERO
+- Desired token: veAERO
+
+John wants a veAERO with a short duration to redeem as soon as possible and obtain AERO tokens. However, Bob sees the offer first and sells his veAERO for the requested amount (calculated based on the ratio, omitted here for simplicity). Since John has no way to specify that he wants a veAERO with a short duration, he ends up with a veAERO locked for 4 years. As users can normally extend the duration of a veAERO but not shorten it, John is unable to adjust the duration to meet his needs.

+# No check for sequencer uptime can lead to dutch auctions executing at bad prices
+
+### Summary
+
+When purchasing from dutch auctions on L2s there is no considering of sequencer uptime. When the sequencer is down, all transactions must originate from the L1. The issue with this is that these transactions use an aliased address. Since the set token contracts don't implement any way for these aliased addressed to interact with the protocol, no transactions can be processed during this time even with force L1 inclusion. If the sequencer goes offline during the the auction period then the auction will continue to decrease in price while the sequencer is offline. Once the sequencer comes back online, users will be able to buy tokens from these auctions at prices much lower than market price.
+
+Thus, a contract [`DutchAuction_veNFT`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L31) that sells NFT by the DutchAuction method when the sequencer falls may sell NFT for a price below market.
+
+Given that this contract is used not only for free sale of NFT by users, but also to liquidate positions where NFT is used as a Collateral - such behavior would be detrimental to all parties to the protocol.
+
+
+
+### Root Cause
+
+Protocol does not check sequencer uptime for Dutch Auction.
+
+### Internal pre-conditions
+
+The user must put NFT up for sale or Loan with collateral NFT should liquidate NFT by auction.
+
+### External pre-conditions
+
+Sequencer falls
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+Auction will sell/buy assets at prices much lower/higher than market price leading to large losses for the set token. Liquidation functionality for Loans with NFT collateral will also be damaged.

+# LimitOrders cannot be updated on `DutchAuction_veNFT`
+
+### Summary
+
+Auctions where the starting price is equal to the floor price are called limitOrders. Sellers sell at a fixed price.
+
+The protocol allows for this case and when creating an auction does not indicate that initAmount is strictly more floorAmount.
+```solidity
+require(_initAmount >= _floorAmount, "Invalid amount");
+```
+When creating such auctions, their tickPerBlock value becomes 0.
+```solidity
+uint curedInitAmount = _initAmount * (10 ** difference);
+uint curedFloorAmount = _floorAmount * (10 ** difference);
+s_CurrentAuction = dutchAuction_INFO({
+ auctionAddress: address(this),
+ nftAddress: _veNFTAddress,
+ nftCollateralID: _veNFTID,
+ sellingToken: sellingToken,
+ owner: owner,
+ initAmount: curedInitAmount,
+ floorAmount: curedFloorAmount,
+ duration: _duration,
+ endBlock: block.timestamp + _duration,
+ tickPerBlock: (curedInitAmount - curedFloorAmount) / _duration,
+ isActive: true,
+ initialBlock: block.timestamp,
+ isLiquidation: _isLiquidation,
+ differenceDecimals: difference
+ });
+```
+
+However, in the editFloorPrice function that allows to reduce floor price auction - newDuration is [calculated by dividing on tickPerBlock](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L203). Thus, for limit orders this operation will always be panic revert. So editFloorPrice does not work for limitOrders.
+
+### Root Cause
+
+`DutchAuction_veNFT::editFloorPrice` does not check that tickPerBlock can be 0, although it can be.
+
+### Internal pre-conditions
+
+1) User creates limitOrder with initAmount = floorAmount
+2) User want to edit floor price

+### External pre-conditions

+# Loans with TaxTokenReceipts as collateral can't be liquidated
+
+### Summary
+
+The ``TaxTokenReceipt.sol`` contract allows users to deposit fee on transfer tokens to it, and it mints them an NFT, that NFT is supposed to be used across the Debita protocol, when users wants to use FOT tokens as collateral. In order to ensure that the NFT is utilized only within the Debita system, the [TaxTokensReceipt::transferFrom()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L93-L120) function is overridden to the following:
+```solidity
+ function transferFrom(
+ address from,
+ address to,
+ uint256 tokenId
+ ) public virtual override(ERC721, IERC721) {
+ bool isReceiverAddressDebita = IBorrowOrderFactory(borrowOrderFactory)
+ .isBorrowOrderLegit(to) ||
+ ILendOrderFactory(lendOrderFactory).isLendOrderLegit(to) ||
+ IAggregator(Aggregator).isSenderALoan(to);
+ bool isSenderAddressDebita = IBorrowOrderFactory(borrowOrderFactory)
+ .isBorrowOrderLegit(from) ||
+ ILendOrderFactory(lendOrderFactory).isLendOrderLegit(from) ||
+ IAggregator(Aggregator).isSenderALoan(from);
+ // Debita not involved --> revert
+ require(
+ isReceiverAddressDebita || isSenderAddressDebita,
+ "TaxTokensReceipts: Debita not involved"
+ );
+ if (to == address(0)) {
+ revert ERC721InvalidReceiver(address(0));
+ }
+ // Setting an "auth" arguments enables the `_isAuthorized` check which verifies that the token exists
+ // (from != 0). Therefore, it is not needed to verify that the return value is not 0 here.
+ address previousOwner = _update(to, tokenId, _msgSender());
+ if (previousOwner != from) {
+ revert ERC721IncorrectOwner(from, tokenId, previousOwner);
+ }
+ }
+```
+As can be seen from the above code snippet the ``to`` or ``from`` address has to be a borrow order, lend order or a loan. Clearly a check whether the ``to`` or ``from`` addresses are a valid auction is missing. This will be problematic when a loan which uses a TaxTokensReceipt NFT as collateral defaults and is liquidated. The auction will be successfully created and the NFT will be successfully transferred to the newly created auction contract. However when another user who wishes to buy the NFT and provide the collateral tokens which will be used to cover the lenders debt the [Auction::buyNFT()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109-L161) function will revert as neither the ``to`` or ``from`` addresses are a valid lend order, borrow order or a loan. This results in loans which utilize the TaxTokenReceipt NFT as collateral and default, to never be successfully liquidated. The NFT and the underlying collateral associated with the NFT will be locked in the ``Auction.sol`` collateral forever, and the lenders will never receive any underlying tokens back, essentially loosing all the principal they provided to the borrower.
+
+### Root Cause
+
+The overdriven [TaxTokensReceipt::transferFrom()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L93-L120) function, only checks whether the ``to`` or ``from`` addresses are a valid borrow order, lend order or a loan in order for a transfer to be successful. Since auctions are not listed, when a user who wishes to buy the NFT via the [Auction::buyNFT()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109-L161) function, won't be able to, as the NFT can't be transferred, and the [Auction::buyNFT()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109-L161) function will revert.

+# DebitaChainlink does not check the last update timestamp of the price feed data
+
+### Summary
+
+In `debitaChainlink.sol` the `getThePrice` function fails to check the last update timestamp of the price feed. This allows stale price data to be used, especially in cases where the price feed is delayed or disrupted, leading to potential inaccuracies.
+
+### Price Monitoring Bot:
+
+> We will have a bot constantly monitoring the price of pairs. If there is a difference greater than 5%, the oracle will be paused until it stabilizes again.
+
+While the proposed bot-based monitoring system helps detect price anomalies, it cannot fully address the risks associated with stale price data due to the following limitations:
+1. **Gradual Price Drift:** Stale prices can drift over time, remaining within the bot’s acceptable deviation threshold (5%). This means the bot may not flag the issue until the discrepancy becomes significant.
+2. **Delayed Detection:** By the time the bot detects a problem, users or the platform may have already incurred significant financial losses.
+3. **Single Point of Failure:** The bot is an external system. If it fails or lags behind in its monitoring duties, stale prices may still be used.
+
+### Root Cause
+
+In [DebitaChainlink.sol:42](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L42)

+
+### External pre-conditions

+# No check for edge cases where tickPerBLock is zero in VeNFT Auction
+
+### Summary
+
+In some edge cases [tickPerBlock may be 0](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L93) due to rounding down.
+```solidity
+uint curedInitAmount = _initAmount * (10 ** difference);
+ uint curedFloorAmount = _floorAmount * (10 ** difference);
+
+ s_CurrentAuction = dutchAuction_INFO({
+ auctionAddress: address(this),
+ nftAddress: _veNFTAddress,
+ nftCollateralID: _veNFTID,
+ sellingToken: sellingToken,
+ owner: owner,
+ initAmount: curedInitAmount,
+ floorAmount: curedFloorAmount,
+ duration: _duration,
+ endBlock: block.timestamp + _duration,
+ tickPerBlock: (curedInitAmount - curedFloorAmount) / _duration,
+ isActive: true,
+ initialBlock: block.timestamp,
+ isLiquidation: _isLiquidation,
+ differenceDecimals: difference
+ });
+```
+The protocol has no limit on duration. That is, purely theoretically, the user can set it to more than curedInitAmount - curedFloorAmount.
+
+This is unlikely, as curedAmount and curedFloorAmount have a dimension of 18 decimals, but again - the protocol has no limit on the size of the input data. Therefore, the situation is possible. And its occurrence will not be a user error
+
+In this situation tickPerBlock will be 0, which breaks the logic of the contract.
+
+Most importantly, getCurrentPrice will always return initAmount. Most importantly, getCurrentPrice will always return initAmount, which means that the price of NFT will never decrease.
+
+Moreover, because the editFloorPrice function does not change tickPerBLock parameter - even after floor price change, the price will always be at initAmount level.
+
+```solidity
+function getCurrentPrice() public view returns (uint) {
+ dutchAuction_INFO memory m_currentAuction = s_CurrentAuction;
+ uint floorPrice = m_currentAuction.floorAmount;
+ // Calculate the time passed since the auction started/ initial second
+ uint timePassed = block.timestamp - m_currentAuction.initialBlock;
+
+ // Calculate the amount decreased with the time passed and the tickPerBlock
+ uint decreasedAmount = m_currentAuction.tickPerBlock * timePassed;
+ uint currentPrice = (decreasedAmount >
+ (m_currentAuction.initAmount - floorPrice))
+ ? floorPrice
+ : m_currentAuction.initAmount - decreasedAmount;
+ // Calculate the current price in case timePassed is false
+ // Check if time has passed
+ currentPrice =
+ currentPrice /
+ (10 ** m_currentAuction.differenceDecimals);
+ return currentPrice;
+ }
+```
+
+
+### Root Cause
+
+No edge case processing when duration is greater than price difference.
+In this case tickPerBlock = 0, although the price should be reduced.

+# Auctioned `taxTokenReceipt` will be permanently locked in the `auction` contract
+
+### Summary
+
+A `receiptID` created through the `taxTokensReceipt` function, if auctioned, becomes permanently unsellable as it will revert when calling the `safeTransferFrom()` function.
+
+The `taxTokensReceipt` contract is designed to wrap unusual ERC20 tokens, like Fee-on-Transfer (FoT) tokens, into an NFT. This concept is similar to `receiptVeNFTs`, except that instead of wrapping an NFT, it wraps ERC20 tokens with unique behaviors. For FoT tokens, transfers require careful handling to ensure that transfers are not allowed free of charge.
+
+In `taxTokensReceipt`, the [`transferFrom()`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L93) function is overridden to enforce that either the `from` or `to` address must belong to a `loan`, `borrowOffer`, or `lendOffer`. This mechanism works as intended throughout most of the protocol. However, issues arise when an NFT from `taxTokenReceipts` is used as collateral in a loan and subsequently needs to be auctioned. During an auction, no one can buy the NFT because neither the sender nor the receiver of the `transferFrom()` function (called within `buyNFT()`) qualifies as a `loan`, `borrowOffer`, or `lendOffer`.
+
+The only way to recover the NFT would be to cancel the auction and return the NFT to the `loan` contract. However, this is not feasible because the [`cancelAuction()`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/auctions/Auction.sol#L168) function is restricted to `onlyOwner`, and the `loan` contract lacks any hooks to manage such a scenario. As a result, the NFT becomes permanently locked within the `auction` contract.
+
+### Root Cause
+
+In the `transferFrom()` function overridden by `taxTokensReceipts`, there is no check to verify if the sender or receiver is an auction, such as by using the mapping [`isAuction[addressAuction]`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L22).
+
+
+### Internal pre-conditions
+
+- FoT tokens are wrapped in a `taxTokensReceipt` NFT.
+- A loan is created using this NFT as collateral with multiple lenders involved.
+- The loan defaults, and the NFT is subsequently auctioned.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+- The borrower wraps their FoT tokens into `taxTokensReceipt` and receives an NFT receipt for the wrapped amount.
+- The borrower then creates a loan with multiple lenders, using this NFT receipt as collateral.
+- At the end of the loan, the borrower decides not to repay, leading to the NFT receipt representing the FoT tokens being put up for auction.
+- The NFT remains permanently locked in the auction contract because any attempt to purchase it results in a revert during the `safeTransferFrom()` function. Furthermore, you cannot cancel the auction due to missing hooks in the loan contract..
+
+
+### Impact
+
+`taxtokensReceipts` NFTs permanently locked when auctioned.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Modify the `transferFrom()` function by using the mapping `isAuction[addressAuction]`. This ensures that if either the receiver or the sender is an auction, the transfer will pass:
+
+Add the interface of auction factory outside the contract:
+```diff
++ interface IAuctionFactoryDebita {
++ function isAuction(
++ address _auction
++ ) external view returns (bool);
++ }
+```
+
+Add the auction factory address through the constructor:
+```diff
++ address public auctionFactory;
+ constructor(
+ address _token,
+ address _borrowOrderFactory,
+ address _lendOrderFactory,
+ address _aggregator
++ address _auctionFactory
+ ) ERC721("TaxTokensReceipts", "TTR") {
+ tokenAddress = _token;
+ borrowOrderFactory = _borrowOrderFactory;
+ lendOrderFactory = _lendOrderFactory;
+ Aggregator = _aggregator;
++ auctionFactory = _auctionFactory;
+ }
+```
+
+Add the changes to the `transferFrom()`:
+```diff
+function transferFrom(
+ address from,
+ address to,
+ uint256 tokenId
+ ) public virtual override(ERC721, IERC721) {
+ bool isReceiverAddressDebita = IBorrowOrderFactory(borrowOrderFactory)

+# Price from the Chainlink Oracle needs to be checked by using the returned values `updatedAt` and `answeredInRound`
+
+### Summary
+
+The price of the principle and collateral needs to be the latest price to ensure that the protocol does not compute the `ratio` with stale price. Hence, the values that are returned by the Chainlink Oracle namely `updatedAt` and `answeredInRound`, needs to be verified.
+
+### Root Cause
+
+The [`DebitaChainlink::getThePrice`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L30) function calls [`priceFeed.latestRoundData()`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L42) to get the most fresh price from the priceFeed. According to the Chainlink documentations, the function is defined as follows:
+
+```solidity
+function latestRoundData(
+ address base,
+ address quote
+ )
+ external
+ view
+ override
+ checkPairAccess()
+ returns (
+ uint80 roundId,
+ int256 answer,
+ uint256 startedAt,
+ uint256 updatedAt,
+ uint80 answeredInRound
+ )
+```
+
+Out of all the returned values, the Debita protocol only uses the `answer` value. The function should check the `updatedAt`, and `answeredInRound` return values to ensure that the price is not too old.

+# `extendLoan(...)` will revert sometimes leading to a DOS
+
+### Summary
+
+In order for a loan to be extended, [**at least 10% of the loan duration has to be transcurred in order to extend the loan**](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L559). However, due to the evaluation of the unused `extendedTime` variable, the `extendLoan(...)` function can sometimes revert thus leading to a DOS preventing users from being able to extend their loans
+
+### Root Cause
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L511

+
+The problem is caused by an overflow when calculating `extendedTime`
+
+
+```solidity
+
+File: DebitaV3Aggregator.sol
+503: offers[i] = DebitaV3Loan.infoOfOffers({
+504: principle: lendInfo.principle,
+505: lendOffer: lendOrders[i],
+506: principleAmount: lendAmountPerOrder[i],
+507: lenderID: lendID,
+508: apr: lendInfo.apr,
+509: ratio: ratio,
+510: collateralUsed: userUsedCollateral,
+511: @> maxDeadline: lendInfo.maxDuration + block.timestamp,
+
+
+File: DebitaV3Loan.sol

+
+590: @> uint extendedTime = offer.maxDeadline -
+591: alreadyUsedTime -
+592: block.timestamp;
+
+```
+
+
+### Internal pre-conditions

+
+### External pre-conditions

+
+### Attack Path
+
+- A loan with a `lendInfo.maxDuration` = 30days is matched (`startedAt`) on 1st Nov, @ 00:00hrs
+- 21 days later ( 21st Nov), the borrower decides to extend
+- the function reverts due to overflow as detailed in the _Root Cause_ section.
+
+### Impact
+
+This leads to DOS for users
+
+### PoC
+
+Given:
+- `lendInfo.maxDuration` = 30days => 2592000
+- `startedAt` = 1st Nov, @ 00:00hrs => 1730415600
+- `block.timestamp` = 21st Nov, @ 00:00hrs => 1732143600
+- `offer.maxDeadline` = ` lendInfo.maxDuration + startedAt` => 1733007600
+
+
+On day 21, the borrower decides to extend the loan
+
+```solidity
+588: @> uint alreadyUsedTime = block.timestamp - m_loan.startedAt;
+588: @> uint alreadyUsedTime = 1732143600- 1730415600 = 1728000
+
+590: @> uint extendedTime = offer.maxDeadline - alreadyUsedTime - block.timestamp;
+590: @> uint extendedTime = 1733007600 - 1728000 - 1732143600
+590: @> uint extendedTime = -864,000
+
+```
+`extendedTime` evaluates to a negative number leading to a revert despite fulfilling the condition that 10% of the duratio must have been transcured
+
+### Mitigation
+
+Modify the `extendLoan()` function by removing the `extendedTime` calculation since it is redundant as shown below
+
+```diff
+
+File: DebitaV3Loan.sol
+547: function extendLoan() public {
+////SNIP .............
+587: if (!offer.paid) {
+588: uint alreadyUsedTime = block.timestamp - m_loan.startedAt;
+589:
+-590: uint extendedTime = offer.maxDeadline -
+-591: alreadyUsedTime -
+-592: block.timestamp;
+
+```

+# Anyone can call `DLOFactory::deleteOrder` multiple times to delete others lend offer from contracts state
+
+### Summary
+
+`DLOImplementation::cancelOffer` is missing check if the offer is active or not, so malicious user can call `cancelOffer` then `addFunds` multiple times to delete others offer loan via `DLOFactory::deleteOrder`
+
+### Root Cause
+
+Cancelling lend offer by calling `DLOImplementation::cancelOffer` can be called multiple times because there are no check if the offer still active, as long as there are `availableAmount` to send to `msg.sender`:
+
+[DebitaLendOffer-Implementation.sol#L144-L159](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L144-L159)
+
+```js
+ function cancelOffer() public onlyOwner nonReentrant {
+ uint availableAmount = lendInformation.availableAmount;
+ lendInformation.perpetual = false;
+ lendInformation.availableAmount = 0;
+ require(availableAmount > 0, "No funds to cancel");
+ isActive = false;
+
+ SafeERC20.safeTransfer(
+ IERC20(lendInformation.principle),
+ msg.sender,
+ availableAmount
+ );
+ IDLOFactory(factoryContract).emitDelete(address(this));
+ IDLOFactory(factoryContract).deleteOrder(address(this));
+ // emit canceled event on factory
+ }
+```
+
+this function ultimately would call `DLOFactory::deleteOrder` and if this called multiple times would overwrite the last index that would be placed on index 0 on the `allActiveLendOrders` and change other mapping like `LendOrderIndex` and `allActiveLendOrders`
+
+### Internal pre-conditions
+
+1. user create 3 lend offer
+
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. malicious user create 2 lend offer
+2. malicious user their cancel their latest lend offer via `DLOImplementation::cancelOffer`
+3. malicious user call `DLOImplementation::addFunds`
+4. repeat until other user lend offer written off the state of the contract
+
+### Impact
+
+calling `DebitaV3Aggregator::matchOffersV3` would be difficult because there are no way to query the address of the active offer via `DLOFactory` struct or via `DLOFactory::getActiveOrders`.
+the only way for normal user or even bot to call `matchOffersV3` if said griefing is done is to manually check the emitted address of past transaction which is time consuming.
+
+### PoC
+
+add these code to `Debita-V3-Contracts/test/local/Loan/TwoLendersERC20Loan.t.sol`:

+```
+
+then run `forge test --mt test_PoC_griefingByDeletingOthersLendOffer` and the test would pass.
+
+### Mitigation
+
+1. add check for `addFunds` to check if the lend offer still active if called directly by owner.
+2. also add check to only cancel the offer if its active.
+
+```diff
+ function addFunds(uint amount) public nonReentrant {

+ );
+ lendInformation.availableAmount += amount;

+ }
+```
+

+# Biased incentives mechanism unfairly benefits lonely lenders
+
+### Summary
+
+When lend and borrow offers are matched, incentives for each party are updated by calling `DebitaIncentives::updateFunds`. This function processes rewards for all collateral-principle pairs passed as input. However, if any pair is not whitelisted, the function halts prematurely and exits with an empty return, skipping the processing of remaining pairs. As a result, the corresponding parties do not receive any incentives for their offers.
+
+### Root Cause
+
+At the end of the `DebitaV3Aggregator::matchOffersV3` function, the `DebitaIncentives::updateFunds` function is invoked to update the incentives for borrowers and lenders involved in the loan.
+
+```javascript
+DebitaIncentives(s_Incentives).updateFunds(
+ offers,
+ borrowInfo.collateral,
+ lenders,
+ borrowInfo.owner
+);
+```
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L631-L636
+
+The `updateFunds` function iterates through each offer's principle-collateral pair to validate if it is whitelisted. If any pair fails this check, the function stops and performs an early return:
+
+```javascript
+function updateFunds(
+ infoOfOffers[] memory informationOffers,
+ address collateral,
+ address[] memory lenders,
+ address borrower
+) public onlyAggregator {
+ for (uint i = 0; i < lenders.length; i++) {
+ bool validPair = isPairWhitelisted[informationOffers[i].principle][
+ collateral
+ ];
+ if (!validPair) {
+@> return;
+}
+```
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L316-L318
+
+If the first pair in the offers array is not whitelisted, no incentives are processed for any of the offers in the array.
+
+### Internal pre-conditions
+
+The lend offer whose principle is not whitelisted is set by the aggregator at the beginning of the array in `DebitaV3Aggregator::matchOffersV3`.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+This biased incentives mechanism grants an unfair competitive advantage to lonely lenders, since mixed offers risk being matched with another lend offer not eligible for rewards. This discourages participation in the platform and creates a skewed incentive structure that may harm the ecosystem's integrity.

+# Pyth Oracle's `getThePrice` function will always revert due to not following the correct procedure to get the price
+
+### Summary
+
+Missing function calls from the `getThePrice` function within the `DebitaPyth` contract will cause the function to revert every time it is called. This will cause the [`DebitaV3Aggregator::matchOffersV3`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274C14-L274C27) to revert every single time if principles or collaterals are using the Pyth Oracle or the Mixed Oracle to get the price.
+
+### Root Cause
+
+The [`DebitaPyth::getThePrice`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L25) function is given below:
+
+```solidity
+function getThePrice(address tokenAddress) public view returns (int) {
+ // falta hacer un chequeo para las l2
+ bytes32 _priceFeed = priceIdPerToken[tokenAddress];
+ require(_priceFeed != bytes32(0), "Price feed not set");
+ require(!isPaused, "Contract is paused");
+
+ // Get the price from the pyth contract, no older than 90 seconds
+ PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ _priceFeed,
+ 600
+ );
+
+ // Check if the price feed is available and the price is valid
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+ require(priceData.price > 0, "Invalid price");
+ return priceData.price;
+ }
+```
+
+As per the [documentation](https://docs.pyth.network/price-feeds/use-real-time-data/evm) of the Pyth Oracle, this function is missing the following line:
+
+```solidity
+ uint fee = pyth.getUpdateFee(priceUpdate);
+ pyth.updatePriceFeeds{ value: fee }(priceUpdate);
+```
+
+As stated in the documentation, `WARNING: These lines are required to ensure the getPriceNoOlderThan call below succeeds. If you remove them, transactions may fail with "0x19abf40e" error.`

+### Impact
+
+This vulnerability makes it so that the Pyth Oracle reverts every time it is called to get the price of any principle or collateral. This will cause arguably the most important function of the protocol [`DebitaV3Aggregator::matchOffersV3`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274C14-L274C27) to revert every single time.
+
+The [`MixOracle::getThePrice`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/MixOracle/MixOracle.sol#L55) also utilizes the Pyth Oracle to get the current price of an asset. This oracle will also revert.

+# Malicious user can Reset activeOrdersCount for `DLOFactory` and DoS deleteOrder functionality
+
+### Summary
+
+Consider the [deleteOrder function in DLOFactory](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207). This function is called from DLOImplementation::cancelOffer and DLOImplementation::acceptLendingOffer.
+
+```solidity
+function deleteOrder(address _lendOrder) external onlyLendOrder {
+ uint index = LendOrderIndex[_lendOrder];
+ LendOrderIndex[_lendOrder] = 0;
+
+ // switch index of the last borrow order to the deleted borrow order
+ allActiveLendOrders[index] = allActiveLendOrders[activeOrdersCount - 1];
+ LendOrderIndex[allActiveLendOrders[activeOrdersCount - 1]] = index;
+
+ // take out last borrow order
+
+ allActiveLendOrders[activeOrdersCount - 1] = address(0);
+
+ activeOrdersCount--;
+ }
+```
+
+The key thing this function does is reduce activeOrdersCount by 1.
+Now consider DLOImplementation::cancelOffer.
+```solidity
+function cancelOffer() public onlyOwner nonReentrant {
+ uint availableAmount = lendInformation.availableAmount;
+ lendInformation.perpetual = false;
+ lendInformation.availableAmount = 0;
+ require(availableAmount > 0, "No funds to cancel");
+ isActive = false;
+
+ SafeERC20.safeTransfer(
+ IERC20(lendInformation.principle),
+ msg.sender,
+ availableAmount
+ );
+ IDLOFactory(factoryContract).emitDelete(address(this));
+ IDLOFactory(factoryContract).deleteOrder(address(this));
+ // emit canceled event on factory
+ }
+```
+As we can see, the only limitation is lendInformation.availableAmount > 0.
+The final part is the addFunds feature, which allows order_owner to add funds and increase the available Amounts.
+
+```solidity
+ function addFunds(uint amount) public nonReentrant {
+ require(
+ msg.sender == lendInformation.owner ||
+ IAggregator(aggregatorContract).isSenderALoan(msg.sender),
+ "Only owner or loan"
+ );
+ SafeERC20.safeTransferFrom(
+ IERC20(lendInformation.principle),
+ msg.sender,
+ address(this),
+ amount
+ );
+ lendInformation.availableAmount += amount;
+ IDLOFactory(factoryContract).emitUpdate(address(this));
+ }
+```
+
+Thus, a malicious user can at the cost of 1 wei repeat the cancelOffer cycle, addFunds will not reset the activeOrdersCount counter. Resetting this counter will be equivalent to DoS of any function that calls it, and can be called by other cancelOffer as well as orders match.
+
+
+### Root Cause
+
+DLOImplementation allows the user to add funds to a contract when the offer has already been cancelled.
+
+Moreover, there is another way how user can do this. `changePerpertual` function calls deleteOrders without any validation checks, so user can call this function many times and reset counter.
+```solidity
+function changePerpetual(bool _perpetual) public onlyOwner nonReentrant {
+ require(isActive, "Offer is not active");
+
+ lendInformation.perpetual = _perpetual;
+ if (_perpetual == false && lendInformation.availableAmount == 0) {
+ IDLOFactory(factoryContract).emitDelete(address(this));
+ IDLOFactory(factoryContract).deleteOrder(address(this));
+ } else {
+ IDLOFactory(factoryContract).emitUpdate(address(this));
+ }
+ }
+```
+
+Or there is not enough validation when removing offer.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+Malicious user creates lendOffer at 1 wei principle.
+
+It can then indefinitely reset activeOrdersCount using the call sequence.
+1) cancelOffer
+2) addFunds
+
+Or, another way
+1) Call change perpetual many times
+
+Thus it can DoS any match order and any lendOffer removal.

+# Pyth Oracle's returned Price's Confidence is Ignored
+
+### Summary
+
+The missing validation of the `confidence` parameter returned by the Pyth Price Feeds may cause the protocol to mismatch borrowers and lenders which could lead to loss of funds. Attackers might take advantage of the wrong prices to create loans that trap honest users.
+
+Even though the README suggests `If there is a difference greater than 5%, the oracle will be paused until it stabilizes again`, any price deviation up to `±4.9%` will also incur substantial losses to users in the protocol.
+
+### Root Cause
+
+The prices fetched by the Pyth Oracle comes with a degree of uncertainty. The [official documentation of Pyth Price Feeds](https://docs.pyth.network/price-feeds/best-practices#confidence-intervals) recommend that these confidence values be used to increase the overall security of the protocol.
+
+In the Debita protocol, [`DebitaPyth::getThePrice`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L32) completely ignores the confidence. The confidence needs to be used by the protocol to ensure that the price feeds are not used by attackers to take advantage of the `matchOffersV3` function to match borrowers with lenders.

+# Missing safeguards in `transferOwnership` function
+
+### Summary
+
+The `transferOwnership` function in the contract fails to follow best practices for transferring ownership. While it utilizes the `onlyOwner` modifier to restrict access to the current owner, the function lacks several safeguards:
+
+1. **No Zero Address Check**: The ownership can be transferred to the zero address, potentially making the contract unmanageable.
+2. **No Two-Step Ownership Transfer**: The current implementation allows the owner to immediately transfer ownership without confirmation or explicit acceptance by the new owner.
+3. **No Event Emission**: The function does not emit an event to log the ownership transfer, which can hinder auditability and transparency.
+
+### Impact
+
+The lack of two-step ownership transfer and other safeguards can lead to unauthorized access, accidental transfers, and difficulties in auditing ownership changes.
+
+### Code Snippet
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLoanOwnerships.sol#L110
+
+### Tool used
+Manual Review
+
+### Mitigation
+
+To mitigate these issues, the following changes are recommended:
+
+1. **Zero Address Check:**
+Ensure that the new owner's address is not the zero address.
+
+2. **Two-Step Ownership Transfer**:
+Implement a two-step process where the current owner sets a pendingOwner, and the new owner must accept the ownership.
+
+3. **Event Emission:**
+Emit an OwnershipTransferred event when the ownership changes to improve auditability.
+
+```solidity
+address public pendingOwner;
+event OwnershipTransferred(address indexed previousOwner, address indexed newOwner);
+
+function transferOwnership(address _newAddress) public onlyOwner {
+ require(_newAddress != address(0), "New owner cannot be the zero address");
+ pendingOwner = _newAddress;
+}
+
+function acceptOwnership() public {
+ require(msg.sender == pendingOwner, "Caller is not the pending owner");
+ emit OwnershipTransferred(admin, pendingOwner);
+ admin = pendingOwner;
+ pendingOwner = address(0);
+}

+# Auctioned `taxTokensReceipt` NFT Blocks Last Claimant Due to Insufficient Funds
+
+### Summary
+
+In the [`Auction::buyNFT`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109) function, users can purchase the current NFT in an auction using the same type of tokens as the underlying asset of the NFT. For example, `taxTokensReceipt` created with FoT tokens must be bought with the same FoT tokens.
+
+During the execution of this function, a `transferFrom()` is performed to transfer funds from the buyer to the auction owner (loan contract). However, it does not account for fees applied during the transfer:
+
+```solidity
+ SafeERC20.safeTransferFrom(
+ IERC20(m_currentAuction.sellingToken),
+ msg.sender,
+ s_ownerOfAuction,
+>> currentPrice - feeAmount // feeAmount: Fee for the protocol
+ );
+```
+Later in the function, it calls [DebitaV3Loan::handleAuctionSell](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L318) to distribute the collateral received from the buyer among the parties involved in the loan:
+```solidity
+ if (m_currentAuction.isLiquidation) {
+ debitaLoan(s_ownerOfAuction).handleAuctionSell(
+>> currentPrice - feeAmount
+ );
+ }
+```
+
+The issue arises because the auction contract does not consider the fee on transfer when selling an auctioned `taxTokensReceipt` NFT. As a result, the final person attempting to claim their share of the collateral on the loan contract will encounter a revert due to insufficient funds.
+
+### Root Cause
+
+Not accounting for the fee on transfer when purchasing a `taxTokensReceipt` NFT being auctioned.
+
+### Internal pre-conditions
+
+- Creation a `taxTokenReceipt` NFT with an FoT token.
+- Use this `taxTokenReceipt` NFT as collateral in a loan with multiple lenders.
+- The loan defaults and the collateral is auctioned.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+- **FoT Token Fee:** 1% fee on every transfer.
+
+#### Steps:
+1. The borrower creates a `taxTokensReceipt` NFT wrapping **10,000 FoT tokens**.
+2. This NFT is used as collateral in a loan with multiple lenders.
+3. At the end of the loan, the borrower defaults and auctions the NFT.
+4. During the auction, another user buys the NFT for **7,000 FoT**, but due to the FoT token's transfer fee, the loan contract receives only **6,930 FoT**.
+5. Inside `handleAuctionSell()`, the system calculates an inflated `tokenPerCollateralUsed` value (used to split collateral among the remaining claimants) because it doesn't account for the transfer fee.
+6. **Impact:** When multiple lenders attempt to claim their share of the collateral, the last lender is unable to claim due to insufficient funds in the contract.
+
+### Impact
+
+The last person attempting to claim the collateral in the loan will be unable to do so.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Take into account the fee on transfer when buying the `taxTokenReceipt` NFT.

+# `_safeMint` should be used instead of `_mint`
+
+### Summary
+
+`_mint` is used by the protocol to mint `ERC721` tokens for borrow/lend order ownerships, as well as to deposit taxable `ERC20` tokens into the protocol. It is highly recommended that `_safeMint` be used to mint the tokens because it has an added check to ensure that `ERC721` tokens are only minted to those addresses that support them.
+
+### Root Cause
+
+In various places in the code, `_mint` is used to mint ownerships of lending, and borrowing tokens. This is discouraged by [OpenZeppelin](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/d11ed2fb0a0130363b1e82d5742ad7516df0e749/contracts/token/ERC721/ERC721.sol#L276) because `_safeMint` ensures that the tokens will only be minted to addresses that support them.
+
+Similarly, `_mint` is used by the [`TaxTokensReceipt::deposit`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L72) to deposit `ERC20` tokens with tax-on-transfer and be provided with an `ERC721` token to be used within the protocol. If the receiving address does not support receiving the `ERC721` token, it will be locked, and the user will lose their deposit.

+If a user deposits their Taxable ERC20 token into the `TaxTokensReceipt` contract using the `deposit` function without their wallet supporting `ERC721` tokens, they will lose the tokens completely.
+
+Users who's wallet do not support `ERC721` tokens will also lose their lend and borrower order ownership `ERC721` tokens.

+# Malicious actor can delete other protocol users' lend orders
+
+### Summary
+
+A malicious actor can delete other protocol users' lend orders by repeatedly calling DLOImplementation::cancelOffer() on his own lend order.
+
+### Root Cause
+
+Due to a missing validation you can add funds to a cancelled order via DLOImplementation::addFunds().
+
+As the only requirement for cancelling an order is to have funds available ([DLOImplementation.sol:148](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L148)), this would allow you to add funds and cancel a lend order repeatedly, even after it has already been cancelled once.
+
+DLOImplementation::cancelOffer() makes a call to DLOFactory::deleteOrder() ([DLOImplementation.sol:157](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L157)).
+In DLOFactory::deleteOrder() the index of the order to be deleted is looked up from the LendOrderIndex mapping. In the case where that order was already deleted, the index will be 0. This will result in the order at index 0 being deleted, even though it's not the order at the address that was passed as an argument.
+
+### Internal pre-conditions
+
+1. There are existing active lend orders
+2. Attacker creates a lend order by calling DLOFactory::createLendOrder()
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Owner of the lend order needs to cancel the order by calling DLOImplementation::cancelOffer()
+2. Owner of the lend order needs to add funds into the cancelled order by calling DLOImplementation::addFunds()
+3. Owner of the lend order needs to call DLOImplemenatation::cancelOffer() again
+4. Repeat steps 2 and 3, causing the deletion of an order each time
+
+### Impact
+
+This can be viewed as a denial of service attack, as the attacker can continuously delete lend orders at minimum cost.
+
+The attacker doesn't gain anything. The cost to the attacker is only the gas fees, as the amount he deposits in order to perform the attack will be refunded back to him as he cancels his order.
+
+The protocol will miss out on the fees from said orders being fulfilled, while the users won't be able to use the protocol as intended.
+
+### PoC
+
+Add the following test to `TwoLendersERC20Loan.t.sol`:
+
+```solidity
+function testShouldDeleteAnotherUsersOrder() public {
+ uint256 index_first = DLOFactoryContract.LendOrderIndex(address(LendOrder));
+ address order_address = DLOFactoryContract.allActiveLendOrders(index_first);
+ assertTrue(DLOFactoryContract.isLendOrderLegit(order_address));
+ assertTrue(LendOrder.isActive());
+
+ uint256 index_second = DLOFactoryContract.LendOrderIndex(address(SecondLendOrder));
+ address order_address_second = DLOFactoryContract.allActiveLendOrders(index_second);
+ assertTrue(DLOFactoryContract.isLendOrderLegit(order_address_second));
+ assertTrue(SecondLendOrder.isActive());
+
+ vm.startPrank(firstLender);
+
+ //cancel lend order
+ LendOrder.cancelOffer();
+
+ //add funds into cancelled order
+ AEROContract.approve(address(LendOrder), 1);
+ LendOrder.addFunds(1);
+
+ //cancel same lend order a second time
+ LendOrder.cancelOffer();
+ vm.stopPrank();
+
+ //assert second order was deleted, even though we did not call cancel on it
+ index_second = DLOFactoryContract.LendOrderIndex(address(SecondLendOrder));
+ assertEq(DLOFactoryContract.allActiveLendOrders(index_second), address(0));
+ assertEq(DLOFactoryContract.activeOrdersCount(), 0);
+ }
+```
+
+### Mitigation
+
+The issue can be fixed in several ways:
+
+1. Do not allow adding funds to cancelled lend order (DLOImplementation::addFunds())
+```diff
+function addFunds(uint amount) public nonReentrant {
+ require(
+ msg.sender == lendInformation.owner ||
+ IAggregator(aggregatorContract).isSenderALoan(msg.sender),
+ "Only owner or loan"
+ );
++ require(isActive == true, "Order is cancelled");
+ SafeERC20.safeTransferFrom(
+ IERC20(lendInformation.principle),
+ msg.sender,
+ address(this),
+ amount
+ );
+ lendInformation.availableAmount += amount;
+ IDLOFactory(factoryContract).emitUpdate(address(this));
+ }
+```
+2. Do not allow order to be cancelled if it's not active (DLOImplementation::cancelOffer())
+```diff
+function cancelOffer() public onlyOwner nonReentrant {
+ uint availableAmount = lendInformation.availableAmount;
+ lendInformation.perpetual = false;
+ lendInformation.availableAmount = 0;
++ require(isActive == true, "Order is already cancelled")
+ require(availableAmount > 0, "No funds to cancel");
+ isActive = false;
+
+ SafeERC20.safeTransfer(
+ IERC20(lendInformation.principle),
+ msg.sender,
+ availableAmount
+ );
+ IDLOFactory(factoryContract).emitDelete(address(this));
+ IDLOFactory(factoryContract).deleteOrder(address(this));
+ // emit canceled event on factory
+ }
+```

+# Fee on transfer tokens is unsupported for `DebitaIncentives.sol::incentivizePair`
+
+### Summary
+
+The protocol uses the TaxTokensReceipts contract to handle fee on transfer tokens.
+
+However, the [incentivizePair](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L225) function does not accept NFT as an award and does not validate incentivizeToken in any way.
+
+Thus, any reward in the FOT token will be calculated incorrectly.
+```solidity
+function incentivizePair(
+ address[] memory principles,
+ address[] memory incentiveToken,
+ bool[] memory lendIncentivize,
+ uint[] memory amounts,
+ uint[] memory epochs
+ ) public {
+ require(
+ principles.length == incentiveToken.length &&
+ incentiveToken.length == lendIncentivize.length &&
+ lendIncentivize.length == amounts.length &&
+ amounts.length == epochs.length,
+ "Invalid input"
+ );
+ for (uint i; i < principles.length; i++) {
+ uint epoch = epochs[i];
+ address principle = principles[i];
+ address incentivizeToken = incentiveToken[i];
+ uint amount = amounts[i];
+ require(epoch > currentEpoch(), "Epoch already started");
+ require(isPrincipleWhitelisted[principle], "Not whitelisted");
+
+ // if principles has been indexed into array of the epoch
+ if (!hasBeenIndexed[epochs[i]][principles[i]]) {
+ uint lastAmount = principlesIncentivizedPerEpoch[epochs[i]];
+ epochIndexToPrinciple[epochs[i]][lastAmount] = principles[i];
+ principlesIncentivizedPerEpoch[epochs[i]]++;
+ hasBeenIndexed[epochs[i]][principles[i]] = true;
+ }
+
+ // if bribe token has been indexed into array of the epoch
+ if (!hasBeenIndexedBribe[epoch][incentivizeToken]) {
+ uint lastAmount = bribeCountPerPrincipleOnEpoch[epoch][
+ principle
+ ];
+ SpecificBribePerPrincipleOnEpoch[epoch][
+ hashVariables(principle, lastAmount)
+ ] = incentivizeToken;
+ bribeCountPerPrincipleOnEpoch[epoch][incentivizeToken]++;
+ hasBeenIndexedBribe[epoch][incentivizeToken] = true;
+ }
+
+ // transfer the tokens
+ IERC20(incentivizeToken).transferFrom(
+ msg.sender,
+ address(this),
+ amount
+ );
+ require(amount > 0, "Amount must be greater than 0");
+
+ // add the amount to the total amount of incentives
+ if (lendIncentivize[i]) {
+ lentIncentivesPerTokenPerEpoch[principle][
+ hashVariables(incentivizeToken, epoch)
+ ] += amount;
+ } else {
+ borrowedIncentivesPerTokenPerEpoch[principle][
+ hashVariables(incentivizeToken, epoch)
+ ] += amount;
+ }
+ emit Incentivized(
+ principles[i],
+ incentiveToken[i],
+ amounts[i],
+ lendIncentivize[i],
+ epochs[i]
+ );
+ }
+ }
+```
+In the lentIncentivesPerTokenPerEpoch or borrowedIncentivesPerTokenPerEpoch field will be written the value of amount - which will be more than the real value that the contract received, and therefore some user will not be able to take the award.
+
+
+

+# Valid principle may not be counted at `DebitaIncentives::updateFunds`
+
+### Summary
+
+Let's consider the [updateFunds function](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L306). It is called at the end of `matchOffersV3` execution and should record information about each user and the amount of principle he lent and received. Depending on this amount, incentive funds are distributed among the users.
+
+```solidity
+ function updateFunds(
+ infoOfOffers[] memory informationOffers,
+ address collateral,
+ address[] memory lenders,
+ address borrower
+ ) public onlyAggregator {
+ for (uint i = 0; i < lenders.length; i++) {
+ bool validPair = isPairWhitelisted[informationOffers[i].principle][
+ collateral
+ ];
+ if (!validPair) {
+ return;
+ }
+ address principle = informationOffers[i].principle;
+
+ uint _currentEpoch = currentEpoch();
+
+ lentAmountPerUserPerEpoch[lenders[i]][
+ hashVariables(principle, _currentEpoch)
+ ] += informationOffers[i].principleAmount;
+ totalUsedTokenPerEpoch[principle][
+ _currentEpoch
+ ] += informationOffers[i].principleAmount;
+ borrowAmountPerEpoch[borrower][
+ hashVariables(principle, _currentEpoch)
+ ] += informationOffers[i].principleAmount;
+
+ emit UpdatedFunds(
+ lenders[i],
+ principle,
+ collateral,
+ borrower,
+ _currentEpoch
+ );
+ }
+ }
+```
+Note that informationOffers contains information about loans issued.
+
+Loans always have one token for collateral, but not necessarily one for principle. That is, informationOffers can store loans with several principles but different collateral.
+
+Each loan is processed sequentially. We are interested in this point.
+
+```solidity
+ bool validPair = isPairWhitelisted[informationOffers[i].principle][
+ collateral
+ ];
+ if (!validPair) {
+ return;
+ }
+```
+
+We see that if some principle,collateral pair has not been whitelisted - the function return. Thus, it aborts its execution and no loan will be processed after this one. Thus, users with valid principles,collateral will not get enough rewards as the function will not count their share.
+
+
+### Root Cause
+
+The function calls return without processing the whole array to the end.
+
+
+### Internal pre-conditions
+
+There will be at least one principle in matchedOffers for which the principle pair, collateral collateral is not whitelisted in the DebitaIncentives contract.
+
+### External pre-conditions

+
+_No response_
+
+### Impact
+

+# `DebitaV3Loan::extendLoan` will revert due to underlow in most cases
+
+### Summary
+
+Consider this particular [point](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L590) in the execution of extendLoan
+
+```solidity
+uint alreadyUsedTime = block.timestamp - m_loan.startedAt;
+
+uint extendedTime = offer.maxDeadline - alreadyUsedTime - block.timestamp;
+```
+Let's decompose this formula to prove that it can underflow in most cases.
+
+`extendedTime = offer.maxDeadline - alreadyUsedTime - block.timestamp` = ` maxDeadline - block.timestamp + startedAt - block.timestamp` = `(startedAt + maxDuration) + startedAt - 2 * block.timestamp`.
+
+It is important to add that `block.timestamp <= startedAt + duration <= startedAt + maxDuration <= maxDeadline`.
+
+Here is a specific example where this will crash due to underflow.
+
+Let's assume that startedAt is 0 for simplicity (counting from the zero point).
+
+duration = 90, maxDuration = 100 => maxDeadline = 0 + 100 = 100.
+
+Let's assume that we call the function in block.timestamp = 60. Then extendedTime = 100 - 2 * 60 = -20 => underflow.
+
+
+### Root Cause
+
+Incorrect calculation formula, it gives underflow in any case when alreadyUsedTime > 1/2 maxDuration.
+
+### Internal pre-conditions
+
+A loan has been created, the user wants to extend the loan.

+# Loans will not be repayable even though the deadline has not passed
+
+### Summary
+
+A lend offer can be repaid as long as [the following condition](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L195) is true: `nextDeadline() >= block.timestamp`. However, when the maximum deadline of each accepted offer the borrower wants to repay is checked, this restriction differs: `offer.maxDeadline > block.timestamp`.
+
+This means that if the `nextDeadline()` of the loan is equal to the `maxDeadline` of the lend offer the borrower wants to repay at the timestamp of the next deadline, they will not be able to repay the offer. Consequently, the loan will be considered defaulted, even though the borrower wanted to repay their debt in time.
+
+This situation occurs when a borrow offer with `duration = x` is [matched](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L434) with a lend offer with `maxDuration = x`.
+
+### Root Cause
+
+[DebitaV3Loan::payDebt()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L210) does not support cases where an accepted offer's `maxDeadline` is equal to the loan's `nextDeadline()` .
+
+### Internal pre-conditions
+
+None.
+
+### External pre-conditions
+
+None.
+
+### Attack Path
+
+1. `DebitaV3Aggregator::matchOffersV3()` is called to match a borrow offer with `duration = x` with a lend offer with `maxDuration = x`.
+2. The borrower calls `DebitaV3Loan::payDebt()` at the exact time of the next deadline to repay an offer. If the offer's maximum deadline is equal to the next deadline, the call will revert and the loan will be defaulted.
+
+### Impact
+
+Whenever the 'maxDeadline' of the offer borrowers want to repay matches the `nextDeadline()`, they will not be able to repay their debt even though they should be allowed to. The loan will be defaulted and the collateral will be at least partially lost.
+
+### PoC
+
+The following should be added to `TwoLendersERC20Loan.t.sol`:
+
+```solidity
+DLOImplementation public AnotherLendOrder;
+DBOImplementation public SecondBorrowOrder;
+```

+Additionally, this should be appended to `TwoLendersERC20Loan.t.sol::setUp()`:

+# The `MixOracle` will stop functioning due to an overflow in the `TarotOracle`.
+
+### Summary
+
+The [`TarotOracle`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/oracles/MixOracle/TarotOracle/TarotPriceOracle.sol#L7) contract is an oracle specifically designed to retrieve prices from UniswapV2 pairs or EQUALIZER. This type of oracles are initially developed to work with a `solc` version < 0.8.0 (the same version used by UniswapV2), but the protocol itself operates with `solc` > 0.8.0, meaning the contract is using the same.
+
+#### Why was it originally designed for `solc` < 0.8.0?
+
+The reason for using a version < 0.8.0 was to allow overflows.
+
+The `TarotOracle` contract was built based on Uniswap’s documentation for integrating with UniswapV2/EQUALIZER:
+- [UniswapV2 Oracle Guide](https://docs.uniswap.org/contracts/v2/guides/smart-contract-integration/building-an-oracle)
+
+In this documentation, there's a section called **Notes On Overflow** that explains:
+>#### Notes on overflow
+> The UniswapV2Pair cumulative price variables are designed to eventually overflow. Specifically, `price0CumulativeLast`, `price1CumulativeLast`, and `blockTimestampLast` will overflow through 0.
+
+Additionally, the `TarotOracle` contract itself contains comments that allow for silent overflows. For example, in the `getPriceCumulativeCurrent` function, we see the following comments:
+
+```solidity
+ function getPriceCumulativeCurrent(
+ address uniswapV2Pair
+ ) internal view returns (uint256 priceCumulative) {
+ priceCumulative = IUniswapV2Pair(uniswapV2Pair)
+ .reserve0CumulativeLast();
+ (
+ uint112 reserve0,
+ uint112 reserve1,
+ uint32 _blockTimestampLast
+ ) = IUniswapV2Pair(uniswapV2Pair).getReserves();
+ uint224 priceLatest = UQ112x112.encode(reserve1).uqdiv(reserve0);
+>> uint32 timeElapsed = getBlockTimestamp() - _blockTimestampLast; // overflow is desired
+>> // * never overflows, and + overflow is desired
+ priceCumulative += (uint256(priceLatest) * timeElapsed);
+ }
+```
+
+From this, we can conclude that when `TarotOracle` is used in `MixOracle`, there will come a point where `TarotOracle` will overflow (due to operating with solc > 0.8.0). At this stage, `MixOracle` would stop functioning properly, and the contract would need to be redeployed.
+
+**Note**: While the `TarotOracle` contract is currently out-of-scope, if we can address the issue by adding a function within `MixOracle` to deploy a new version of `TarotOracle` when an overflow occurs, I believe this issue might be valid.
+
+
+### Root Cause
+
+Inside [`MixOracle`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/oracles/MixOracle/MixOracle.sol#L19), the failure to deploy a new `TarotOracle` when it overflows.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+- The protocol functions normally, using the oracles to handle transactions.
+- After some time, Alice makes a transaction in the protocol where the price of `EQUAL/USD` is needed, but neither the `Pyth` nor `Chainlink` Oracles provide this price. The protocol then uses the `MixOracle`, which in turn uses the `TarotOracle` to get the price of `EQUAL/wFTM` and the `Pyth` Oracle to get `wFTM/USD`.
+- After extensive use, the `TarotOracle` eventually overflows when attempting to fetch the price of `EQUAL/wFTM`, causing the `MixOracle` to become ineffective. Consequently, the contracts must be redeployed.
+
+### Impact
+
+Functionality of the `MixOracle` halts when the `TarotOracle` starts overflowing.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Every time the `TarotOracle` overflows, deploy a new instance to ensure the continued use of the `MixOracle`.

+
+### Root Cause
+

+# Flash Loan Borrows can take most of the incentive.
+
+### Summary
+
+The amount of incentive that a lender and borrower will receive in the current round depends on the amount of [principle](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L323) they have pledged and received accordingly.
+
+```solidity
+function updateFunds(
+ infoOfOffers[] memory informationOffers,
+ address collateral,
+ address[] memory lenders,
+ address borrower
+ ) public onlyAggregator {
+ for (uint i = 0; i < lenders.length; i++) {
+ bool validPair = isPairWhitelisted[informationOffers[i].principle][
+ collateral
+ ];
+ if (!validPair) {
+ return;
+ }
+ address principle = informationOffers[i].principle;
+
+ uint _currentEpoch = currentEpoch();
+
+ lentAmountPerUserPerEpoch[lenders[i]][
+ hashVariables(principle, _currentEpoch)
+ ] += informationOffers[i].principleAmount;
+ totalUsedTokenPerEpoch[principle][
+ _currentEpoch
+ ] += informationOffers[i].principleAmount;
+ borrowAmountPerEpoch[borrower][
+ hashVariables(principle, _currentEpoch)

+
+ emit UpdatedFunds(
+ lenders[i],
+ principle,
+ collateral,
+ borrower,
+ _currentEpoch
+ );
+ }
+ }
+```
+
+Here the protocol has two problems at once.
+1. There is no protection against instant transactions.
+That is nothing prevents the borrower to take flash loan on which after he will take credit, and then in the same transaction pay minimum interest to the protocol and lender. Thus, the borrower will simply squeeze a maximum number of shares in DebitaIncentivize and take as many rewards for this era as it would be profitable to cover flash loan.
+
+2. What makes this attack even easier is that there is no check that the lender and borrower are not the same person. That is malicious user can also avoid costs for minimal apr.
+
+
+### Root Cause
+
+- No protection against instant loans
+- Incentive has no maximum number of shares per person
+- Lender and borrower can be the same person
+
+### Internal pre-conditions
+
+Someone should incentive a specific epoch
+
+### External pre-conditions

+_No response_
+
+### Attack Path
+
+The user sees big rewards in the current era.
+
+He decides to get the most shares in this era.
+
+For this he either takes flash loan, or uses his own funds and in one transaction rolls up a lot of instant loans according to the following scheme.
+
+1. Create Borrow offer
+2. Loan Lend offer
+3. Match this offers (pay small taxes to protocol)
+. Repay loan to yourself
+5. Output collateral and principle
+6. Go back to step 1
+
+As long as the small fee that a user pays for such a round is less than the reward for a specific epoch, this action is beneficial.

+# A borrower may pay more interest that he has specified, if orders are matched by a malicious actor
+
+### Summary
+
+In the ``DebitaV3Aggregator.sol`` contract, anybody can match borrow and lend orders by calling the [matchOffersV3()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274-L647) function. When borrowers create their borrow orders they specify a maximum APR they are willing to pay. However the [matchOffersV3()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274-L647) function allows the caller to specify an array of 29 different lend orders to be matched against each borrow offer. Another important parameter is the ``uint[] memory lendAmountPerOrder`` which specifies the amount of principal tokens each lend order will provide. A malicious user can provide smaller amounts for a part of the ``lendAmountPerOrder`` params, such that the borrower pays a higher APR on this amounts. The problem arises due to the fact that there are no minimum restrictions on the ``lendAmountPerOrder`` (except it being bigger than 0), and the fact that solidity rounds down on division.
+```solidity
+uint updatedLastApr = (weightedAverageAPR[principleIndex] * amountPerPrinciple[principleIndex]) / (amountPerPrinciple[principleIndex] + lendAmountPerOrder[i]);
+uint newWeightedAPR = (lendInfo.apr * lendAmountPerOrder[i]) / amountPerPrinciple[principleIndex];
+weightedAverageAPR[principleIndex] = newWeightedAPR + updatedLastApr;
+```
+As we can see form the code snippet above, when the ``newWeightedAPR`` is calculated if the APR specified by the lender of a lend order and the lendAmountPerOrder product is less than the amountPerPrinciple[principleIndex], 0 will be added to the weightedAverageAPR for the borrow order. Now if the borrower has requested a lot of funds, paying much bigger APR than the one he specified on **2% - 3%** on those funds results in big loss for the borrower.
+Let's consider a simplified example of the PoC provided in the PoC section
+ - A borrower creates a borrow offer for **500_000e6 USDC**, with **WETH** as collateral, a **5% APR**, and a ratio of **2_500e6 USDC** for **1e18 WETH**, for a duration of **150 days**.
+ - There might be several lenders that have created orders that match the params of the borrow order, for simplicity consider there is one lender - LenderA that matches the params, and he has provided **495_000e6 USDC** as available principal, or is left with such amount, after his lend order was matched with other borrow orders.
+ - Now the person who is matching the orders can either create a lend offer with higher APR, or find another lender who provides an accepted principal by the borrower, and accepts the offered collateral, but has a higher APR than the one specified by the borrower.
+ - We assumer the user matching the orders creates a lend order with **10% APR**, which is double the APR specified by the borrower (instead of only hurting the borrower by making him pay more interest, he is also going to profit).
+ - When matching the orders, the user will first provide a lendAmountPerOrder of **200_000e6 + 1** from the lend order of LenderA, and then 28 more lendAmountPerOrder **200e6** each from the lend order with 10% APR
+ - Since the max length of the lendAmountPerOrder is 29, for a bigger impact the malicious user will call the [matchOffersV3()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274-L647) function once more, this time setting the first lendAmountPerOrder to be **286_391e6 + 1**, and the next amounts for the lendAmountPerOrder will be **286e6**
+ - This results in two separate loan orders, however they are both for the same borrow order, in this way the borrower will have to pay **5% APR** on **486_391e6 + 2 USDC**, and **10% APR** on **13_608e6 USDC**. The borrower will have to pay double the APR he specified on **~2.72%** of the funds he received(excluding the Debita protocol withheld fees, on which the borrower still pays interest). This results in the borrower paying **10_553_568_492 USDC** instead of **10_273_952_054 USDC**, which is a difference of **279_616_438 ~279e6 USDC**, for the 150 day duration of the loan. Note that the above calculation are provided in the PoC below.
+
+ In conclusion this results in the borrower paying double the APR he specified on part of the principal he received. Keep in mind that the collateral is worth more than the principal, so the borrower is incentivized to repay his debt back, for some reason Debita has decided to not utilize liquidation if the nominal dollar value drops below the dollar nominal value of the principal, and rely only on loan duration for loan liquidations. Also in the above scenario the malicious actor profited by collecting a bigger interest rate on his assets.

+### Attack Path
+
+_No response_
+
+### Impact
+When borrow orders are big (there are numerous cases where people have taken out millions in loans, by providing crypto assets as collateral), malicious actors can match borrow and lend orders in such a way that the borrower pays much more APR than he has specified on a percentage of the principal he receives. This is a clear theft of funds, and in most cases the attacker can profit, if he matches the borrow order with a lend order of himself with a higher APR, and once the loan is repaid, collect the interest rate.

+
+As can be seen from the logs above, and as explained in the example in the summary section, alice will overpay **~279e6 USDC**, this attack can be performed on multiple borrowers. **(( 10553568492 - 10273952054 ) / 10273952054) \* 100 = 2.72%**. The borrower overpays by more than **1%** and more than **$10**, which I believe satisfies the requirement for a high severity.

+# updateFunds may miss some whiteListedPair due to incorrect use of `return`
+
+### Summary
+
+The DebitaV3Aggregator will call `updateFunds` if match offer successfully. The function `updateFunds` only consider the token pair `[infomration[i].principle, collateral]` which is in whitelist.
+But due to incorrect use `return` in `updateFunds`, it may miss some valid pair. This will result in the incentives corresponding to the offer not being processed.
+
+### Root Cause
+
+In https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L306

+ address borrower
+ ) public onlyAggregator {
+ for (uint i = 0; i < lenders.length; i++) {
+ bool validPair = isPairWhitelisted[informationOffers[i].principle][
+ collateral
+ ];
+
+ //@audit the following principle will not take into account, even it is in whitelist.
+ if (!validPair) {
+ return;
+ }
+ //...
+}
+```
+The function use `return` when meet one token pair is not in whitelist.But this will miss the following valid pair.
+For example, there are 2 offers.
+```solidity
+offer1: priniciple = token1, collateral = token2, isWhiteListed[token1][token2] = false
+offer2: priniciple = token3, collateral = token2, isWhiteListed[token3][token2] = true
+```
+The function `updateFunds` will return when process `offer1` and miss `offer2` which is valid.
+
+### Internal pre-conditions
+
+1. The loan has more than 2 offer.
+2. There exists [principle, collateral] token pair which is not in DebitaIncentive's whitelist.
+3. There is a legal offer behind the illegal offer.

+
+ if (lentAmount > 0) {

+

+ );
+
+ porcentageBorrow = (borrowAmount * 10000) / totalBorrowAmount;
+
+ for (uint j = 0; j < tokensIncentives[i].length; j++) {
+ address token = tokensIncentives[i][j];
+ uint lentIncentive = lentIncentivesPerTokenPerEpoch[principle][

+ ];
+ uint borrowIncentive = borrowedIncentivesPerTokenPerEpoch[
+ principle
+ ][hashVariables(token, epoch)];
+ require(
+ !claimedIncentives[msg.sender][
+ hashVariablesT(principle, epoch, token)
+ ],
+ "Already claimed"
+ );
+ require(
+ (lentIncentive > 0 && lentAmount > 0) ||

+
+ emit ClaimedIncentives(
+ msg.sender,

+ }
+ }
+ }
+```
+So, percentageLent is calculated as
+
+```solidity
+ porcentageLent = (lentAmount * 10000) / totalLentAmount;
+```
+Where lentAmount is the total amount lent in this round by a particular user. totalLentAmount - The amount of funds borrowed in this round.
+
+Obviously, the 10000 multiplier is too small. For example, if totalLentAmount = 1e6 USDC (without decimals) - all borrowers who have borrowed < 100 USDC will receive 0 rewards, but what they do not receive - also large depositors will not receive, thus the funds are simply frozen in contract.

+# Interest paid for non perpetual loan during loan extension is lost when the borrower repays debt
+
+### Summary
+
+When a borrower call `extendLoan()`to extend a loan to the max deadline, interest is accrued to the lender up until the time the loan is extended and the lender's `interestPaid` is updated as well for accounting purpose when calculating the interest with `calculateInterestToPay()`
+
+### Root Cause

+
+As shown below interest is accrued and `interestPaid` is also accrued correctly
+```solidity

+657: interestOfUsedTime -
+658: interestToPayToDebita;
+659: }
+660: loanData._acceptedOffers[i].interestPaid += interestOfUsedTime;
+
+```
+
+The problem is that when a borrower extends a loan and later repays the loan a the end of the `maxDeadline` that the loan was extended to, the unpaid interest is used to **overwrite the previously accrued interest** (as shown on L238 below) thus leading to a loss of interest to the borrower
+
+```solidity

+If the loan is not perpetual, the amount of `interest - feeOnInterest` is added to offer's `interestToClaim` prop
+
+```solidity
+ if (lendInfo.perpetual && lendInfo.owner == currentOwnerOfOffer) {
+ loanData._acceptedOffers[index].debtClaimed = true;
+ IERC20(offer.principle).approve(address(lendOffer), total);
+ lendOffer.addFunds(total);
+ } else {
+ loanData._acceptedOffers[index].interestToClaim =
+ interest -
+ feeOnInterest;
+ }
+```
+
+From the above implementation, it is evident that for any debt the lender will claim `offer.paid` will always be true. As a result, in [`DebitaV3Loan::claimDebt`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L271C1-L286C6) function, the else block will never be executed.
+
+```solidity
+ if (offer.paid) {
+ _claimDebt(index);
+@> } else {
+ // if not already full paid, claim interest
+ claimInterest(index);
+ }
+```
+
+[`DebitaV3Loan::claimInterest`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L259C1-L269C6) function is implemented as `internal` and it is only called in `DebitaV3Loan::claimDebt`. This implementation makes this function redundant.
+
+Now there are two possible scenarios, firstly, protocol team says "we don't want to implement the functionality for lender to claim interest only". Furthermore, if we look into [`DebitaV3Loan::calculateInterestToPay`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L721C1-L738C6) function, the return value assumes that there is some interest amount that is previously paid.
+
+```solidity
+ return interest - offer.interestPaid;
+```
+
+Now in the second scenario, protocol team rectifies the implementation of `DebitaV3Loan::claimInterest` function.
+
+### Root Cause
+
+In consideration to above scenarios and code implementation, let's look into [`DebitaV3Loan::_claimDebt`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L288C1-L311C6) function's implementation. When lender wants to claim debt, he calls `DebitaV3Loan::claimDebt` function, which internally calls `DebitaV3Loan::_claimDebt` function and in this function before transferring tokens, `offer.interestToClaim` is set to `0'.
+
+```solidity
+ function _claimDebt(uint index) internal {
+ LoanData memory m_loan = loanData;
+ IOwnerships ownershipContract = IOwnerships(s_OwnershipContract);
+
+ infoOfOffers memory offer = m_loan._acceptedOffers[index];
+ require(
+ ownershipContract.ownerOf(offer.lenderID) == msg.sender,
+ "Not lender"
+ );
+ require(offer.paid == true, "Not paid");
+ require(offer.debtClaimed == false, "Already claimed");
+ loanData._acceptedOffers[index].debtClaimed = true;
+ ownershipContract.burn(offer.lenderID);
+ uint interest = offer.interestToClaim;
+@> offer.interestToClaim = 0;
+
+ SafeERC20.safeTransfer(
+ IERC20(offer.principle),
+ msg.sender,
+ interest + offer.principleAmount
+ );
+
+ Aggregator(AggregatorContract).emitLoanUpdated(address(this));
+ }
+```
+
+Here lies the actual problem. The `offer` in the above code is a cached local variable. As a result, the offer's state is not updated in the storage. Which means, even if the tokens are transferred, the storage will remain unchanged and there will always be a balance in books for `interestToClaim` against a particular offer. For this particular scenario, in current code implementation the `PoC` is provided in below relevant section.
+
+Now another problem is that, if the protocol team provides the functionality for the lender to claim the interest, which is more likely because `DebitaV3Loan::claimInterest` function updates the state correctly.
+
+```solidilty
+ function claimInterest(uint index) internal {
+ IOwnerships ownershipContract = IOwnerships(s_OwnershipContract);
+ infoOfOffers memory offer = loanData._acceptedOffers[index];
+ uint interest = offer.interestToClaim;
+
+@> require(interest > 0, "No interest to claim");
+
+@> loanData._acceptedOffers[index].interestToClaim = 0;
+ SafeERC20.safeTransfer(IERC20(offer.principle), msg.sender, interest);
+ Aggregator(AggregatorContract).emitLoanUpdated(address(this));
+ }
+```
+
+Because in `DebitaV3Loan::_claimDebt` function, the state is not updated correctly, the lender will be able to receive the interest twice, once by claiming debt and then by claiming interest, because `require(interest > 0, "No interest to claim");` will be by passed first time because of lack of state update in `DebitaV3Loan::_claimDebt` function.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+Even if the tokens are transferred, the storage will remain unchanged and there will always be a balance in books for `interestToClaim` against a particular offer.
+
+Second impact, if `DebitaV3Loan::claimInterest` function is implemented correctly:
+Because in `DebitaV3Loan::_claimDebt` function, the state is not updated correctly, the lender will be able to receive the interest twice because in `DebitaV3Loan::claimInterest` function `require(interest > 0, "No interest to claim");` will be by passed first time.

+# Incorrectly implemented `changeOwner` function across `buyOrderFactory`, `AuctionFactory` and `DebitaV3Aggregator` contracts does not allow changing the owner.
+
+### Summary
+
+The `changeOwner` function is used for changing the owner across `buyOrderFactory`, `AuctionFactory` and `DebitaV3Aggregator` contracts respectively.
+```solidity
+ function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+```
+There are two issues here:-
+ 1. The require check `require(msg.sender == owner, "Only owner");` which takes the local `owner`, i.e `owner` from parameter and checks against the `msg.sender` instead of taking the contract's `owner`
+ 2. The way owner is being assigned -> `owner = owner`, this will shadow the actual `owner` of the contract and assign it to the parameter passed, disallowing the admin to change owner.
+
+### Root Cause
+
+In [`buyOrderFactory.sol:189`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L189), [`AuctionFactory.sol:221`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L221) and [`DebitaV3Aggregator.sol:685`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L685), there is an issue with the way `owner` is getting assigned, as well as the require block taking the shadowing owner, i.e owner from parameter instead of actual contract's `owner`
+```solidity
+ function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner"); <@ - Shadowing occurs here
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner; <@ - Shadowing occurs here
+ }
+```
+This will not allow the admin to change owner as intended.
+
+### Internal pre-conditions
+
+Admin needs to be owner
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Admin calls any of the change owner functions in the `buyOrderFactory`, `AuctionFactory` and `DebitaV3Aggregator` contracts.
+
+### Impact
+
+The admin cannot change the owner of the mentioned contracts, this can be crucial in a case where admin keys get compromised or there's a need to change owner as per business requirements.
+
+### PoC
+
+The below test case was added in `BuyOrder.t.sol`
+```solidity
+ function testChangeOwner() public {
+ // Get current owner
+ address currentOwner = factory.owner();
+
+ // We need to prank as the owner to change the owner
+ vm.startPrank(currentOwner);
+ vm.expectRevert("Only owner");
+ factory.changeOwner(address(0x01)); // <@ - Change owner will always fail unless the param is the actual owner, which is not useful
+
+ }
+ ```
+
+### Mitigation
+
+It is recommended to change the parameter of `changeOwner` functions from `owner` to `_owner`.
+```diff
+- function changeOwner(address owner) public {
++ function changeOwner(address _owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+- owner = owner;
++ owner = _owner;
+ }
+```

+# Legitimate Lend Orders Can Delete Arbitrary Lend Orders
+
+### Summary
+
+The lack of proper access control in the `deleteOrder` function allows a legitimate lend order to delete any other lend order, causing unauthorized deletion of lend orders for other users. A malicious lend order can exploit this by calling `deleteOrder` with the address of any lend order they wish to remove.
+
+
+
+### Root Cause
+
+In `DLOFactory.sol:103` {https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L102C4-L105C6}, the `deleteOrder` function does not verify that the caller (`msg.sender`) is the same as the lend order being deleted (`_lendOrder`). The modifer `onlyLendOrder` just checks if the address is a valid lender. This oversight allows any legitimate lend order to delete any other lend order, not just their own.
+
+### Internal pre-conditions
+
+1. There must be at least one legitimate lend order registered in the system (the attacker).
+2. Other lend orders exist in `allActiveLendOrders` that the attacker aims to delete.
+
+
+### External pre-conditions
+
+No external pre-conditions.
+
+### Attack Path
+
+1. The attacker operates a legitimate lend order (`AttackerLendOrder`) registered in the system.
+2. The attacker calls the `deleteOrder` function, passing in the address of another lend order (`VictimLendOrder`) they wish to delete.
+3. The `onlyLendOrder` modifier checks that `msg.sender` (`AttackerLendOrder`) is legitimate, which it is.
+4. The function proceeds without verifying that `msg.sender` is not the same as `_lendOrder`.
+5. `VictimLendOrder` is deleted from `allActiveLendOrders`, and mappings are updated accordingly.
+6. `VictimLendOrder` loses money that already transfered when called `createLendOrder`
+
+### Impact
+
+ - The affected lend orders suffer from unexpected removal from the platform.
+ - Their lending offers are no longer active, wich leads to loss of funds of the users.
+ - The attacker can eliminate competition or disrupt the lending market to their advantage.
+
+### PoC
+
+No PoC.
+
+### Mitigation
+
+Modify the `deleteOrder` function to ensure that only the lend order itself can delete its entry:
+
+```solidity
+function deleteOrder(address _lendOrder) external onlyLendOrder{
+ require(msg.sender == _lendOrder, "Caller must be the lend order");
+ ... //rest of code
+}
+```

+# Insufficient oracle validation
+
+## Summary
+``DebitaChainlink::getThePrice`` is used to get the price of tokens, the problem is that [the function](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L42C8-L42C59) does not check for freshness on price.
+## Vulnerability Details
+There is no freshness check on the timestamp of the prices, so old prices may be used if [[OCR](https://docs.chain.link/architecture-overview/off-chain-reporting)](https://docs.chain.link/architecture-overview/off-chain-reporting) was unable to push an update in time.
+## Impact
+Old prices mean users will get wrong values for their assets, and since the token prices are used in many contracts, stale data could be catastrophic for the project.
+## Code Snippet
+The timestamp field is ignored, which means there's no way to check whether the price is recent enough:
+```javascript
+ (, int price, , , ) = priceFeed.latestRoundData();
+```
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L42C8-L42C59
+## Tool Used
+Manual Review
+## Recommendation
+Add a staleness threshold number of seconds configuration parameter, and ensure that the price fetched is within that time range.
+Also consider to add checks on the return data with proper revert messages if the price is stale or the round is incomplete.

+# BuyOrderFactory owner will fail to transfer ownership due to incorrect ownership assignment in the contract
+
+### Summary
+
+The incorrect ownership assignment in the `changeOwner` function will cause a failure to transfer ownership for the contract owner, as the current implementation assigns the `owner` variable to itself rather than the `newOwner` parameter. This results in the contract owner permanently retaining control unless redeployed, leading to governance and maintainability challenges.
+
+
+### Root Cause
+
+In [buyOrderFactory.sol:186](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L186:L190)
+the assignment in the `changeOwner` function incorrectly sets `owner = owner` instead of `owner = _newOwner`.
+```Solidity
+function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+```
+### Attack Path
+
+1. The current owner calls the `changeOwner` function with a valid `_newOwner` address within the first 6 hours after contract deployment.
+2. The function executes but incorrectly assigns `owner = owner` instead of `owner = _newOwner`.
+3. Ownership is not transferred, and the contract remains under the control of the original owner.
+
+
+### Impact
+
+The contract owner cannot transfer ownership, permanently locking the administrative control of the contract to the deployer. This prevents governance actions (e.g., adjusting fees or upgrading proxies) from being delegated or handed over in the future.
+
+### PoC
+
+Please add this test function to `BuyOrder.t.sol`
+```Solidity
+function testChangeBuyOrderFactoryOwner() public {

+# Ownerships' tokenURI fail to determine borrower vs lender
+
+### Summary
+
+The Ownerships' tokenURI function in DebitaLoanOwnerships.sol incorrectly assign Borrower / Lender loan ownership type when minting to lenders and borrowers.
+
+### Root Cause
+
+In the `tokenUri` function in [DebitaLoanOwnerships.sol:L84](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLoanOwnerships.sol#L84), the Ownership NFT type is determined by
+```solidity
+string memory _type = tokenId % 2 == 0 ? "Borrower" : "Lender";
+```
+which does not apply in Debita V3 where lenders loan ownership are minted first (one or many), and borrower loan ownership last, as seen in matchOffersV3:
+```solidity
+// Mint ownership for each lender first
+for (uint i = 0; i < lendOrders.length; i++) {
+ uint lendID = IOwnerships(s_OwnershipContract).mint(lendInfo.owner);
+}
+// Later... mint borrower ownership last
+uint borrowID = IOwnerships(s_OwnershipContract).mint(borrowInfo.owner);
+```
+
+### Internal pre-conditions
+
+The Ownerships contract must be initialized and properly linked to DebitaV3Aggregator.
+
+### External pre-conditions
+
+A lending/borrowing match must occur, triggering the minting of ownership NFTs.
+
+### Attack Path
+
+Evil user may be able to convince the victim to buy a Lender NFT for a profit and receive a Borrower NFT instead.
+
+_No response_
+
+### Impact
+
+1. Loan ownership NFT badges/images will incorrectly identify if the holder is a lender or borrower
+2. Position type misrepresentation: NFTs minted to lenders will show as "Borrower" positions, and NFTs minted to borrowers will show as "Lender" positions
+3. Potential for misleading trades based on NFT metadata where users might buy/sell positions believing they represent the opposite role
+4. Compromised historical record accuracy of who was lender vs borrower in past loans
+
+For the sake of reference, below are two Debita v2 ownership NFT badges correcty dispaying lender vs borrower:
+
+Loan Borrower: https://ftmscan.com/nft/0x41746483f983e6863ef266a1267bb54638407b7f/17960
+Loan Lender: https://ftmscan.com/nft/0x41746483f983e6863ef266a1267bb54638407b7f/17805
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Either parametrize the Ownerships' mint function for discriminating borrower vs lender, or add function for selecting Borrower vs Lender by tokenId.
+
+Example implementation:
+
+```solidity
+mapping(uint256 => bool) public isBorrower;
+
+function mint(address to, bool _isBorrower) public onlyContract returns (uint256) {
+ id++;
+ _mint(to, id);
+ isBorrower[id] = _isBorrower;
+ return id;
+}
+
+function tokenURI(uint256 tokenId) public view override returns (string memory) {
+ require(tokenId <= id, "Token Id does not exist");
+ string memory _type = isBorrower[tokenId] ? "Borrower" : "Lender";
+ // ... rest of tokenURI logic ...

+### Summary
+
+Users create buy order to buy an NFT `wantedToken` at their desired ratio of the NFT's `lockedAmount`
+
+When a user calls `SellNFT()` to sell the `wantedToken` to the buy order in exchange for the `buyToken`, the `wantedToken` is trnasfered into the buy order contract.
+
+### Root Cause
+
+The problem is that there is no way for the creator of the buy order to withdraw/use the NFT. hence the NFT is lock in the `BuyOrder` contract without a way to withdraw.

+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L92

+# Deleting the Last Buy Order Causes Index Mapping Errors
+
+### Summary
+
+Deleting the last buy order causes index misalignment and stale mappings, leading to data inconsistencies.
+
+A lack of conditional handling when deleting the last buy order in `allActiveBuyOrders` will cause an array misalignment and incorrect index mapping for both `BuyOrderIndex` and `allActiveBuyOrders`, as the function `_deleteBuyOrder` inadvertently overwrites entries and creates stale mappings.
+
+### Root Cause
+
+In `buyOrderFactory.sol:_deleteBuyOrder`, the function does not handle cases where the buy order to be deleted is the last one in the `allActiveBuyOrders` array. This results in overwriting the last entry with itself, creating an unnecessary `address(0)` entry without effectively removing it.
+
+Example:
+- In `buyOrderFactory.sol:140-150`, the `_deleteBuyOrder` function lacks a conditional check for cases where the index equals `activeOrdersCount - 1`.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L75
+
+### Internal pre-conditions
+
+1. `activeOrdersCount` must be at least 1.
+2. The buy order to be deleted is the last one in the `allActiveBuyOrders` list (`index == activeOrdersCount - 1`).
+
+
+### External pre-conditions
+
+None.
+
+### Attack Path
+
+1. A buy order reaches its end and calls `_deleteBuyOrder`.
+2. The `_deleteBuyOrder` function attempts to delete a buy order at the last index of `allActiveBuyOrders`.
+3. The function inadvertently overwrites `allActiveBuyOrders[activeOrdersCount - 1]` with `address(0)`, leaving a stale entry.
+4. The `BuyOrderIndex` mapping is updated incorrectly, creating potential misalignments in future order retrievals.
+
+### Impact
+
+The protocol will have inconsistent data within the `allActiveBuyOrders` and `BuyOrderIndex` mappings, potentially leading to incorrect data reads, disrupted user experience, and possible failures in buy order-related functionalities. Future interactions with buy orders could be affected due to stale or erroneous mappings, causing potential financial or operational disruption.
+
+
+### PoC
+
+N/A
+
+### Mitigation
+
+To handle the deletion of the last buy order correctly, add a conditional check to handle cases where `index == activeOrdersCount - 1`. If it is the last buy order:
+- Set `BuyOrderIndex[_buyOrder]` to `0` without swapping or overwriting.
+- Directly decrement `activeOrdersCount` without modifying `allActiveBuyOrders`.

+# Redundant Initialization in `changeOwner`
+
+### Summary
+
+The redundant statement `owner = owner;` in the `changeOwner` function has no functional impact but increases code confusion and bloats the contract unnecessarily.
+
+The redundant initialization `owner = owner` will cause no actual state change for the protocol owner, as this line is effectively a no-operation. It introduces unnecessary complexity for developers reviewing or auditing the contract.
+
+### Root Cause
+
+In buyOrderFactory:186 ( https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L186 ) , the statement `owner = owner;` has no effect because it reassigns the variable to its current value, leading to dead code.
+
+Example:
+- The line `owner = owner;` performs no meaningful action.
+
+### Internal pre-conditions
+
+1. The `changeOwner` function is called.
+
+### External pre-conditions
+
+No external conditions are required for this issue to manifest, as it is a code inefficiency rather than an exploitable vulnerability.
+
+### Attack Path
+
+No direct attack path exists for this issue.
+
+### Impact
+
+Permanent inability to transfer ownership
+Risk of protocol being locked if original owner loses access
+No way to update critical protocol parameters that require owner access
+Potential need for contract redeployment to fix ownership issues

+# `isBuyOrderLegit` Not Updated on Deletion
+
+### Summary
+
+The missing update to the `isBuyOrderLegit` mapping will cause logical inconsistencies and potential misuse for buy orders as deleted orders remain marked as legitimate, bypassing checks in functions like `onlyBuyOrder`.
+
+### Root Cause
+
+In `buyOrderFactory.sol`, the `_deleteBuyOrder` function does not include a line to set the `isBuyOrderLegit` mapping to `false` when a buy order is deleted.
+
+Examples:
+- In `buyOrderFactory.sol:75`, the `_deleteBuyOrder` function fails to update `isBuyOrderLegit[_buyOrder]` to `false`.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L75
+
+### Internal pre-conditions
+
+1. A buy order must have been created using `createBuyOrder()`, setting its legitimacy flag (`isBuyOrderLegit`) to `true`.
+2. The `_deleteBuyOrder()` function is called on the buy order without updating the legitimacy flag.
+
+### External pre-conditions
+
+1. No external checks are required for this issue to manifest.
+
+### Attack Path
+
+na
+
+### Impact
+
+The protocol may allow unintended interactions with deleted buy orders. This could lead to logical inconsistencies, unauthorized access, or even potential exploits if other mechanisms rely on `isBuyOrderLegit` for validation.
+
+
+### PoC
+
+na
+
+### Mitigation
+
+Update the `_deleteBuyOrder` function to set the `isBuyOrderLegit` mapping to `false`:
+```solidity
+function _deleteBuyOrder(address _buyOrder) public onlyBuyOrder {
+ uint index = BuyOrderIndex[_buyOrder];
+ BuyOrderIndex[_buyOrder] = 0;
+
+ allActiveBuyOrders[index] = allActiveBuyOrders[activeOrdersCount - 1];
+ allActiveBuyOrders[activeOrdersCount - 1] = address(0);
+

+# Changing owner of the `AuctionFactory` is impossible because it uses incorrect variable
+
+### Summary
+
+In the `AuctionFactory.changeOwner` function, the variable name of input parameter is same as contract owner variable name.
+This causes changing owner revert.
+
+### Root Cause
+

+In the [changeOwner](https://github.com/sherlock-audit/2024-11-debita-finance-v3/tree/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L218), it also uses the same input variable name, `owner`.

+### Summary
+
+The `changeOwner` function of the `AuctionFactory` contract uses the same input variable name as the `owner` variable.
+As a result, changing owner is impossible.
+
+### Root Cause
+
+The input variable name of `changeOwner` function is same as owner storage variable.

+
+In the function, `owner` is treated as a local variable. Therefore, if the contract owner tries to change the owner, `msg.sender` will always differ from `owner`.

+# The `DebitaPyth` contract should call `pyth.updatePriceFeeds()` function before calling `pyth.getPriceNoOlderThan`
+
+### Summary
+
+The `pyth` oracle requires to call the `pyth.updatePriceFeeds()` function before calling `pyth.getPriceNoOlderThan`.
+However, there is no code to do this in the `DebitaPyth` contract. As a result, matching lend and borrow orders reverts.
+
+### Root Cause
+
+The `DebitaPyth.getThePrice` function gets the token's price, no older than 600 seconds from `pyth` oracle from [L32](https://github.com/sherlock-audit/2024-11-debita-finance-v3/tree/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L32).
+The function calls `pyth.getPriceNoOlderThan(_priceFeed, 600)`, it checks the timestamp on the blockchain and compares it to the timestamp for the Pyth price. If the Pyth price's timestamp is more than 600 seconds in the past, then a `StalePrice` error occurs.
+
+```solidity
+L32: PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ _priceFeed,
+ 600
+ );
+```
+
+[Here](https://docs.pyth.network/price-feeds/create-your-first-pyth-app/evm/part-1#:~:text=Before%20that%2C%20however,error%20won%27t%20occur.), there are the following sentences:"Before that, however, the function calls updatePriceFeeds on the Pyth contract. This function takes a payload of bytes[] that is passed into the function itself. The Pyth contract requires a fee to perform this update; the code snippet above calculates the needed fee using getUpdateFee. The caller of this function can pass in a recent Pyth price update as this payload, guaranteeing that the StalePrice error won't occur."
+This means that the `pyth` oracle requires the users should call `updatePriceFeeds()` function to get the latest price like the following code in [here](https://docs.pyth.network/price-feeds/create-your-first-pyth-app/evm/part-1#:~:text=%7D-,function%20updateAndMint(bytes%5B%5D%20calldata%20pythPriceUpdate)%20external%20payable%20%7B,%7D,-//%20Error%20raised%20if).
+
+```solidity
+ uint updateFee = pyth.getUpdateFee(pythPriceUpdate);
+ pyth.updatePriceFeeds{ value: updateFee }(pythPriceUpdate);
+```
+
+However, the `DebitaPyth.getThePrice` function does not call `pyth.updatePriceFeeds()` function.
+The `DebitaPyth.getThePrice` function is used to match the lend and borrow orders in the `DebitaV3Aggregator.matchOffersV3()`.
+As a result, the `matchOffersV3()` function reverts because the price is not updated.
+
+### Internal pre-conditions
+
+A user creates the order with `pyth` oracle.
+
+### External pre-conditions
+
+1. None
+
+### Attack Path
+
+None
+
+### Impact
+
+The matching lend and borrow orders reverts because the price of `pyth` is not updated.
+
+### PoC
+
+None
+
+### Mitigation
+
+Add the following code before L32 in the `DebitaPyth.getThePrice` function and improve related functions to execute added code.
+
+```solidity
+ uint updateFee = pyth.getUpdateFee(_priceFeed);
+ pyth.updatePriceFeeds{ value: updateFee }(_priceFeed);
+```

+# The protocol does not account for the exponent of the `pyth` oracle when retrieving the token's price
+
+### Summary
+
+The `pyth.getPriceNoOlderThan` function returns the price in the format of `price * 10^expo` described in [here](https://api-reference.pyth.network/price-feeds/evm/getPriceNoOlderThan#:~:text=Sample%20price%20object%3A). However, the protocol does not take this into consideration when using the price. As a result, the order matching mechanism is compromised.
+
+### Root Cause
+
+The `DebitaPyth.getThePrice` function gets the token's price from `pyth` oracle from [L40](https://github.com/sherlock-audit/2024-11-debita-finance-v3/tree/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L40).
+
+```solidity
+ PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ _priceFeed,
+ 600
+ );
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+ require(priceData.price > 0, "Invalid price");
+L40: return priceData.price;
+```
+
+And the returned price is used to match the lend and borrow orders in the `DebitaV3Aggregator.matchOffersV3()` function from [L350](https://github.com/sherlock-audit/2024-11-debita-finance-v3/tree/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L40) and L451.
+
+```solidity
+L350: uint ValuePrincipleFullLTVPerCollateral = (priceCollateral_BorrowOrder *
+ 10 ** 8) / pricePrinciple;
+L451: uint fullRatioPerLending = (priceCollateral_LendOrder *
+ 10 ** 8) / pricePrinciple;
+```
+
+However, directly using the returned price is incorrect because it does not account for the exponent of the `pyth` price feed.
+The `PythStructs.Price` struct has the following structure:
+
+```solidity
+File: Debita-V3-Contracts\node_modules\@pythnetwork\pyth-sdk-solidity\PythStructs.sol
+ struct Price {
+ // Price
+ int64 price;
+ // Confidence interval around the price
+ uint64 conf;
+ // Price exponent
+ int32 expo;
+ // Unix timestamp describing when the price was published
+ uint publishTime;
+ }
+```
+
+Let's assume `pyth.getPriceNoOlderThan()` function returns the following value.
+This is described in [here](https://api-reference.pyth.network/price-feeds/evm/getPriceNoOlderThan#:~:text=Sample%20price%20object%3A).
+
+```solidity
+{
+ price: 123456789n,
+ conf: 180726074n,
+ expo: -8,
+ publishTime: 1721765108n
+}
+```
+
+The `price` above is in the format of `price * 10^expo`. So, the price in above mentioned sample represents the number 123456789 * 10^(-8) = 1.23456789 in this case. This means the price of token is `1.23456789`, not `123456789`.
+However, the `DebitaV3Aggregator.matchOffersV3()` function uses `123456789` and do not use 10^(-8).
+As a result, `ratiosForBorrower` and `userUsedCollateral` are calculated incorrectly and this breaks the matching of lend and borrow orders.
+
+### Internal pre-conditions
+
+A user creates the order with `pyth` oracle.
+
+### External pre-conditions
+
+1. None
+
+### Attack Path
+
+Let's consider the following scenarion:
+- There are matching available lending and borrowing order.
+ - collateral token: cbBTC
+ - principle token: AXP
+ - all of principle and collateral oracle of borrow order: pyth
+- The `pyth` oracle returns the price of `cbBTC` as 90,000e8(90,000USD) and the price of `AXP` as `30,000,000`(300 USD)
+ - The exponent of `cbBTC` is -8: https://www.pyth.network/price-feeds/crypto-cbbtc-usd#:~:text=Price-,Exponent,-%2D8
+ - The exponent of `AXP` is -5: https://www.pyth.network/price-feeds/equity-us-axp-usd#:~:text=Price-,Exponent,-%2D5
+ - `priceCollateral_BorrowOrder` is calculated as `90,000e8`, not `90,000` and `pricePrinciple` is calculated as `30,000,000`, not `300`.
+
+As a result, `ratiosForBorrower` is calculated greater than actual value and this causes valid matching revert from L536.
+
+```solidity
+File: Debita-V3-Contracts\contracts\DebitaV3Aggregator.sol
+ require(
+L536: weightedAverageRatio[i] >=
+ ((ratiosForBorrower[i] * 9800) / 10000) &&
+ weightedAverageRatio[i] <=
+ (ratiosForBorrower[i] * 10200) / 10000,
+ "Invalid ratio"
+ );
+```
+
+For simplicity, this scenario uses the same oracle for collateral and principle.
+If one uses `pyth` oracle and other uses `chainlink` oracle, there still exists this vulnerability.
+
+Also, this causes incorrect calculation of `userUsedCollateral`.
+
+### Impact
+
+The price that does not account for the exponent breaks the order matching mechanism.
+This causes user's loss of funds.
+
+### PoC
+
+None
+
+### Mitigation
+
+It is recommended to modify the code to take into account the exponent of the `pyth` price feed when using the token's price.

+# The protocol does not account for the precision decimals of the `chainlink` oracle when retrieving the token's price
+
+### Summary
+
+The `latestRoundData()` function of chainlink oracle returns the price which contains precision decimals. However, the protocol does not take this into consideration when using the price. As a result, the order matching mechanism is compromised.
+
+### Root Cause
+
+The `DebitaChainlink.getThePrice` function gets the token's price from `chainlink` oracle from [L42](https://github.com/sherlock-audit/2024-11-debita-finance-v3/tree/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L40).
+
+```solidity
+L42: (, int price, , , ) = priceFeed.latestRoundData();
+```
+
+And the returned price is used to match the lend and borrow orders in the `DebitaV3Aggregator.matchOffersV3()` function from [L350](https://github.com/sherlock-audit/2024-11-debita-finance-v3/tree/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L40) and L451.
+
+```solidity
+L350: uint ValuePrincipleFullLTVPerCollateral = (priceCollateral_BorrowOrder *
+ 10 ** 8) / pricePrinciple;
+L451: uint fullRatioPerLending = (priceCollateral_LendOrder *
+ 10 ** 8) / pricePrinciple;
+```
+
+However, directly using the returned price is incorrect because it does not account for the precision decimals.
+
+The `AggregatorV3Interface` has [`decimals()`](https://docs.chain.link/data-feeds/api-reference#decimals:~:text=Get%20the%20number%20of%20decimals%20present%20in%20the%20response%20value.) function and it gets the number of decimals present in the response value.
+
+```solidity
+ function decimals() external view returns (uint8);
+```
+
+Thus, actual USD price of the token is `response value / decimals()`.
+For `USDC / USD`, if the oracle returns the `price` as `999934` and `decimals() = 6`, the the price of `USDC` is `0.999934` USD.
+However, the `DebitaV3Aggregator.matchOffersV3()` function uses `999934` and do not use `decimals()`.
+As a result, `ratiosForBorrower` and `userUsedCollateral` are calculated incorrectly and this breaks the matching of lend and borrow orders.
+
+### Internal pre-conditions
+
+A user creates the order with `chainlink` oracle.
+
+### External pre-conditions
+
+1. None
+
+### Attack Path
+
+None
+
+### Impact
+
+The price that does not account for the `decimals()` breaks the order matching mechanism.
+This causes user's loss of funds.
+
+### PoC
+
+None
+
+### Mitigation
+
+It is recommended to modify the code to take into account the `decimals()` of the `AggregatorV3Interface` when using the token's price.

+# The `MixOracle.getThePrice` function calculates the price incorrectly using the `TarotOracle.getResult` function as the TWAP price
+
+### Summary
+
+The `MixOracle.getThePrice` function calculates the price using the `TarotOracle` contract and the `pyth` oracle. However, it incorrectly uses the `TarotOracle.getResult` function as the TWAP price, which disrupts the matching mechanism for lend and borrow orders.
+
+### Root Cause
+
+In the [MixOracle.getThePrice](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/MixOracle/MixOracle.sol#L40) function, the `twapPrice112x112` is retrieved from the `TarotOracle.getResult` function at L50. It then calculates the price of 1 token1 in USD using `twapPrice112x112` and the price from the `pyth` oracle at L65.
+
+```solidity
+ ITarotOracle priceFeed = ITarotOracle(_priceFeed);
+ address uniswapPair = AttachedUniswapPair[tokenAddress];
+ require(isFeedAvailable[uniswapPair], "Price feed not available");
+L50: (uint224 twapPrice112x112, ) = priceFeed.getResult(uniswapPair);
+ [...]
+ int amountOfAttached = int(
+ (((2 ** 112)) * (10 ** decimalsToken1)) / twapPrice112x112
+ );
+L65: uint price = (uint(amountOfAttached) * uint(attachedTokenPrice)) /
+ (10 ** decimalsToken1);
+```
+
+The `TarotOracle.getResult` function returns the time-weighted average of `reserve0 + price`, rather than the TWAP price, from L46.
+Also, it does not synchronize with `uniswapV2Pair`.
+
+```solidity
+File: contracts\oracles\MixOracle\TarotOracle\TarotPriceOracle.sol
+ function getPriceCumulativeCurrent(
+ address uniswapV2Pair
+ ) internal view returns (uint256 priceCumulative) {
+ priceCumulative = IUniswapV2Pair(uniswapV2Pair)
+ .reserve0CumulativeLast();
+ (
+ uint112 reserve0,
+ uint112 reserve1,
+ uint32 _blockTimestampLast
+ ) = IUniswapV2Pair(uniswapV2Pair).getReserves();
+ uint224 priceLatest = UQ112x112.encode(reserve1).uqdiv(reserve0);
+ uint32 timeElapsed = getBlockTimestamp() - _blockTimestampLast; // overflow is desired
+ // * never overflows, and + overflow is desired
+L46: priceCumulative += (uint256(priceLatest) * timeElapsed);
+ }
+```
+
+This means that the `twapPrice112x112` in the `MixOracle.getThePrice` function is not the correct TWAP price. Consequently, the `DebitaV3Aggregator.matchOffersV3` uses an incorrect price to match lend and borrow orders.
+
+### Internal pre-conditions
+
+A user creates the order with MixOracle.
+
+### External pre-conditions
+
+1. None
+
+### Attack Path
+
+None
+
+### Impact
+
+The incorrect price from the `MixOracle` disrupts the matching mechanism for lend and borrow orders.
+This causes user's loss of funds.
+
+### PoC
+
+Change the code in the `MixOracle.getThePrice` function to get the correct price from the `uniswapV2Pair`.
+
+```diff
+File: code\Debita-V3-Contracts\contracts\oracles\MixOracle\MixOracle.sol

++ uint realPrice = (uint(attachedTokenPrice)) * wftmPrice / (10 ** decimalsToken1);
++ return (int(uint(price)), int(uint(realPrice)));
+ }
+```
+
+And add the following `testTotalPrice` test function in the `OracleTarotUSDCEQUAL.t.sol`.
+
+```solidity
+File: code\Debita-V3-Contracts\test\fork\Loan\ltv\Tarot-Fantom\OracleTarotUSDCEQUAL.t.sol
+ function testTotalPrice() public{
+ IUniswapV2Pair(EQUALPAIR).sync();

+ vm.warp(block.timestamp + 1201);
+ IUniswapV2Pair(EQUALPAIR).sync();
+ (int originPrice, int realPrice) = DebitaMixOracle.getTotalPrice(EQUAL, EQUALPAIR);
+ console.logString(" price:");
+ console.logUint(uint(originPrice));
+ console.logString("actual price:");
+ console.logUint(uint(realPrice));
+ console.logString("price diff ratio:");
+ console.logUint(uint(originPrice / realPrice));
+ }
+```
+
+Use the following command to test above function.
+
+```bash
+forge test --rpc-url https://mainnet.base.org --match-path test/fork/Loan/ltv/Tarot-Fantom/OracleTarotUSDCEQUAL.t.sol --match-test testTotalPrice -vvv
+```
+
+The result is as following:
+
+```text
+ mix price:
+ 147639521176897807
+ actual price:
+ 926069876
+ price diff ratio:
+ 159425897
+```
+
+This indicates that the mix price is 147,639,521,176,897,807, while the actual price is 926,069,876. The mix price is significantly higher than the actual price.
+
+### Mitigation
+
+It is recommended to change the code as following:
+
+```diff
+File: code\Debita-V3-Contracts\contracts\oracles\MixOracle\MixOracle.sol
+ function getThePrice(address tokenAddress) public returns (int) {

+
+And, anyone can call the `DebitaV3Aggregator.matchOffersV3` function.
+Let's assume that the malicious attacker creates the malicious contract which implements the `getThePrice` and creates orders using this contract as oracle.

+
+### Attack Path
+
+- Alice creates a lend order with the principal token as `AERO` and the collateral token as `EQUAL`.
+- A malicious attacker, Bob, creates a harmful contract whose `getThePrice` function returns an inflated price for the `EQUAL` token.
+- Bob then creates a borrow order that is available to match with Alice's lend order, using the created contract as the oracle.
+- If Bob calls `DebitaV3Aggregator.matchOffersV3` to match Alice's lend order with his borrow order, he can steal Alice's `AERO`.
+
+### Impact
+
+Malicious attackers can steal another users' funds.
+
+### PoC
+
+None
+
+### Mitigation
+
+Add the mechanism to check that the order's oracle is valid oracle.

+# The `DebitaChainlink.getThePrice` function does not check if the price is latest
+
+### Summary
+
+"The `DebitaPyth.getThePrice` function checks if the price is latest; however, the `DebitaChainlink.getThePrice` function does not perform this check, which can lead to users losing funds."
+
+### Root Cause
+
+The `DebitaPyth.getThePrice` function checks if the price is latest from [L32](https://github.com/sherlock-audit/2024-11-debita-finance-v3/tree/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L32).
+
+```solidity
+L32: PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ _priceFeed,
+ 600
+ );
+```
+
+However, the `DebitaChainlink.getThePrice` function does not check it.
+
+```solidity
+L42: (, int price, , , ) = priceFeed.latestRoundData();
+```
+
+The `latestRoundData` function returns [`updatedAt`](https://docs.chain.link/data-feeds/api-reference#decimals:~:text=updatedAt%3A-,Timestamp%20of%20when%20the%20round%20was%20updated,-.), which is the timestamp indicating when the round was last updated.
+
+```solidity
+function latestRoundData() external view
+ returns (
+ uint80 roundId,
+ int256 answer,
+ uint256 startedAt,
+ uint256 updatedAt,
+ uint80 answeredInRound
+ )
+```
+
+In the `DebitaChainlink.getThePrice` function, it is ignored.
+As a result, expired prices can be used, leading to potential losses for users.
+
+### Internal pre-conditions
+
+A user creates the order with `chainlink` oracle.
+
+### External pre-conditions
+
+1. None
+
+### Attack Path
+
+None
+
+### Impact
+
+Expired prices from the Chainlink oracle can result in users losing funds.
+
+### PoC
+
+None
+
+### Mitigation
+
+Add the `chainlinkValidityPeriod` variable and change the code of the `DebitaPyth.getThePrice` as following:
+
+```diff
+- (, int price, , , ) = priceFeed.latestRoundData();
++ (, int price, ,uint256 updatedAt , ) = priceFeed.latestRoundData();
++ require(updatedAt + chainlinkValidityPeriod >= block.timestamp, "expired price");

+# DoS of `cancelAuction` and `editFloorPrice` functions in the `Auction` contract
+
+### Summary
+
+The `DebitaV3Loan.createAuctionForCollateral` function creates auctions, with the `DebitaV3Loan` contract as the owner.
+In the `Auction` contract, only the owner is permitted to cancel an auction and edit the floor price. However, the `DebitaV3Loan` contract lacks the functionality to perform these actions.
+
+### Root Cause
+
+The `Auction.cancelAuction` and `editFloorPrice` functions have the `onlyOwner` modifier from [L168](https://github.com/sherlock-audit/2024-11-debita-finance-v3/tree/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L168) and L194.
+
+```solidity
+ modifier onlyOwner() {
+ require(msg.sender == s_ownerOfAuction, "Only the owner");
+ _;
+ }
+L168: function cancelAuction() public onlyActiveAuction onlyOwner
+ [...]
+ function editFloorPrice(
+ uint newFloorAmount
+L194: ) public onlyActiveAuction onlyOwner
+```
+
+And the `s_ownerOfAuction` is set in the constructor.
+
+```solidity
+ constructor(
+ uint _veNFTID,
+ address _veNFTAddress,
+ address sellingToken,
+ address owner,
+ uint _initAmount,
+ uint _floorAmount,
+ uint _duration,
+ bool _isLiquidation
+ ) {
+ s_ownerOfAuction = owner;
+ factory = msg.sender;
+ }
+```
+
+The `AuctionFactory.createAuction` function sets the owner of auction as `msg.sender` from L85.
+
+```solidity
+ DutchAuction_veNFT _createdAuction = new DutchAuction_veNFT(
+ _veNFTID,
+ _veNFTAddress,
+ liquidationToken,
+L85: msg.sender,
+ _initAmount,
+ _floorAmount,
+ _duration,
+ IAggregator(aggregator).isSenderALoan(msg.sender) // if the sender is a loan --> isLiquidation = true
+ );
+```
+
+And the `AuctionFactory.createAuction` function is called in the `DebitaV3Loan.createAuctionForCollateral` function from L470.
+
+```solidity
+L470: address liveAuction = auctionFactory.createAuction(
+ m_loan.NftID,
+ m_loan.collateral,
+ receiptInfo.underlying,
+ receiptInfo.lockedAmount,
+ floorAmount,
+ 864000
+ );
+```
+
+Therefore, the owner of the auction is the `DebitaV3Loan` contract. This implies that only the `DebitaV3Loan` contract can call the `cancelAuction` and `editFloorPrice` functions. However, the `DebitaV3Loan` contract does not contain any code to invoke these functions. Consequently, the auction cannot be canceled, and the floor price cannot be edited.
+
+### Internal pre-conditions
+
+None
+
+### External pre-conditions
+
+1. None
+
+### Attack Path
+
+None
+
+### Impact
+
+The auction creators are unable to cancel the auction or edit the floor price.
+
+### PoC
+
+None
+
+### Mitigation
+
+Implement the functionality for canceling an auction and editing the floor price in the `DebitaV3Loan` contract.

+# Malicious use of erc20 tokens as incentives in DebitaIncentives.sol
+
+### Summary
+
+No check on return value of [`transferFrom`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L269) and the also not checking the difference between previous and new balance of address(this) after [`transferFrom` in `incentivizePair :: DebitaIncentives`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L269) could lead to state inconsistency and thereby negatively affecting users incentives when some erc20 tokens are used maliciously used
+
+### Root Cause
+
+1. A missing check on [`transferFrom`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L269). A malicious user could incentivize a pair in [`incentivizePair`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L225C14-L225C29) with a token(e.g USDT) which does not revert but fails silently (due to allowance issues, insufficient balances, etc) since the return value is not properly checked, it could appear to succeed leading to increase in some state variables ( [`lentIncentivesPerTokenPerEpoch`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L278), [`borrowedIncentivesPerTokenPerEpoch` ](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L282)) which in turn affects the claim of users' incentives as the balance of the contract as been maliciously increased
+2. Lack of check of the difference between previous balance before `transferFrom` and after.
+A malicious user could use a token (e.g., cUSDCv3) which contains a special case for amount == type(uint256).max in their transfer functions that results in only the malicious user's balance being transferred. This would increase the variables ( [`lentIncentivesPerTokenPerEpoch`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L278), [`borrowedIncentivesPerTokenPerEpoch` ](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L282)) luring other users to interact with the given principles and the end of the day users will not be able to claim incentives as the amount used by the malicious user is not the amount transfered.
+
+### Impact
+
+1. DOS in users' incentives
+2. State inconsistency of mapping variables
+
+
+### Mitigation
+
+Checking the difference of the amount before and after [`transferFrom`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L269)

+# Premature Function Termination Causing Lender Incentive Token Loss
+
+### Summary
+
+Premature Function Termination Causing Lender Incentive Token Loss
+
+### Root Cause
+
+In `DebitaIncentives.sol:317`, the `return` statement directly ends the execution of the function. If the `informationOffers` array contains `validPair = isPairWhitelisted[informationOffers[i].principle[collateral==false;` in the middle or at the beginning, the data of subsequent lenders will not be updated. This is because when `validPair == false` is satisfied, the function executes `return;`, causing the function to terminate prematurely.

+# use of fee-on-transfer token in DebitaIncentives.sol
+
+### Summary
+
+In the Q&A section in Readme.md the protocol states that [`Fee-on-transfer tokens will be used only in TaxTokensReceipt contract`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/README.md?plain=1#L20C3-L20C72). Meanwhile in the DebitaIncentives.sol there are no measures in place to check if the incentiveTokens have fee-on-transfer property. This could lead to users not been able to claim their incentives at some point.
+
+### Root Cause
+
+The use of fee-on-transfer token (e.g DAI) as [`tokensIncentives`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L144C28-L144C44) could cause DOS when users claim incentives. As for every incentive paid by the contract to users, there is a percentage fee on the contract, this will lead to abnormal reduction in the contract incentive token balance. Which could eventually lead users not been to claim incentives at some point because the incentive token balance would not be enough for the users [`amountToClaim`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L200)

+# Some ERC20 will revert when transfer zero value on fees for `feeAddress`
+
+## Summary
+
+Sometimes calculating fee for `feeAddress`, `feeAmount` will be equal `0`, So for any token that doesn't support transfer zero value, it will revert.
+
+## Vulnerability Detail
+When creating an Auction, a user can set a token for payment whatever they want. Logically, it's never impact to the protocol. But if we see at the codebase which calculating fee, it's possible to get zero amount.
+ Let's see code below :
+ https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L124-L140
+
+ Let's create a scenario :
+ 1. At the worst case, protocol has 0.05% fee for `feeAddress`
+ 2. `fee = 50` and denominator = `10_000`
+ 3. Let's say the price is `200`
+ 4. `feeAmount` = `(200 * 50) / 10_000`
+ 5. `feeAmount = 1`
+ 6. Since the price is equal or more higher than `200`, it's no problem, but the price lower than `200`, `feeAmount` will zero
+
+## Recomendation
+
+Add check for fee transfer
+
+```diff
++ if(feeAmount > 0){
+ SafeERC20.safeTransferFrom(
+ IERC20(m_currentAuction.sellingToken),
+ msg.sender,
+ feeAddress,
+ feeAmount
+ );
++ }
+```

+# The `buyOrderFactory::changeOwner` fails to change owner as it should
+
+## Impact
+### Summary
+The `buyOrderFactory::changeOwner` is designed to change the owner of the `buyOrderFactory` contract, passing owner privileges from the old owner to the new owner. However, this function will not be able to change the `owner` of the contract due to conflicting variable naming convention.
+
+### Vulnerability Details
+The vulnerability of this function lies in the fact that the name of the input parameter for the `buyOrderFactory::changeOwner` function conflicts with the storage variable `owner` in the sense that the two variables are not differentiated.
+Here is the link to the function in question https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L186-L190 and also shown in the code snippet below
+
+```javascript
+@> function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+```
+
+### Impact
+As a result of this conflicting variable naming convention, the solidity compiler fumbles in when to user `owner` as the parameter input of the `buyOrderFactory::changeOwner` function and when to use `owner` as state varable in the `buyOrderFactory` contract.
+In particular, if the `buyOrderFactory::changeOwner` function is called by the `buyOrderFactory::owner`, the call reverts due to the first require statement. This is because `msg.sender` is compared against `owner`, the parameter input instead of `buyOrderFactory::owner`. On the other hand, if `owner` as in the input parameter calls the `buyOrderFactory::changeOwner` function, the function executes but owner is not changed.
+Hence, the owner cannot be changed, breaking the protocol's functionality.
+
+## Proof of Concept
+1. Prank the owner of `buyOrderFactory` to call the `buyOrderFactory::changeOwner` function which reverts with `Only owner` message.
+2. Prank the address we wish to set as the new owner to call the `buyOrderFactory::changeOwner` function. This executes successfully but using the getter function shows that the `buyOrderFactory::owner` has not changed.

+
+## Tools Used
+
+Manual Review and Foundry
+
+
+## Recommended Mitigation Steps
+Consider changing the name of the input parameter of the `buyOrderFactory::changeOwner` function in such a way that it does not conflict with any state variables. For instance, we could use `address _owner` instead of `address owner` as shown below:
+
+```diff
+- function changeOwner(address owner) public {
++ function changeOwner(address _owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+- owner = owner;
++ owner = _owner;
+ }
+```

+
+1. Attacker creates a lending order
+2. Attacker calls cancelOffer() to delete their order, which decreases activeOrdersCount
+3. Attacker calls addFunds()
+4. Attacker repeats steps 2-3 until activeOrdersCount reaches 0
+5. Other users try to cancel their orders but fail because activeOrdersCount is 0, activeOrdersCount-- will revert
+
+### Impact
+
+All other lenders cannot cancel their lending orders and retrieve their funds.

+# Variable Shadowing in `ChangeOwner` Function of multiple contracts Prevents Ownership Transfer
+
+### Summary
+
+The `changeOwner` function is used in 3 different contracts:
+- [debitaV3Aggregator.sol: 683](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682),
+- [AuctionFactory.sol:219](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L218),
+- [buyOrderFactory.sol: 186](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L186),
+
+
+ The function is all three instances is unusable and does not update the `owner` state variable due to `variable shadowing`.
+- The authorization check `require(msg.sender == owner)` validates `msg.sender` against the input parameter `owner ` instead of the state variable `owner`, making it impossible for the current owner to call the function (with a new owner address).
+- The local function parameter "owner" `shadows the state variable`, causing the assignment statement to have no effect on the intended state variable.
+As a result, `the owner of the contract cannot be changed using this function.`
+
+### Root Cause
+ `changeOwner` function of three contracts:
+
+```solidity
+ @--> function changeOwner(address owner) public { //@audit : input param has same name as state var
+ require(msg.sender == owner, "Only owner");
+ ......
+ .......
+ owner = owner;
+ }
+
+```
+The Input parameter `owner` in `changeOwner` has the same name as the state variable `owner` of the contract. Within the function, the local parameter takes precedence, effectively "hiding" the state variable.
+ - so everytime `owner` calls `changeOwner` function with a new owner address as input argument, the `require` statement does not pass.
+ - also, the statement `owner = owner; ` only operates on the local parameter and does not modify the state variable.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1.Owner has to call `changeOwner` function .
+
+### Impact
+
+- After Initial deployment, any attempt to transfer/change ownership fails.
+
+
+### PoC
+
+In file `BasicDebitaAggregator.t.sol`
+
+add the following test function in `DebitaAggregatorTest` contract:
+
+```solidity
+function testChangeOwnerBug() public {
+ // Get initial owner (deployer/test contract)
+ address initialOwner = address(this);
+ address newOwner = address(0x123);
+
+
+
+ // - should fail because msg.sender is checked against input parameter , not original owner
+ vm.prank(initialOwner);
+ vm.expectRevert("Only owner"); // Reverts because msg.sender != owner parameter
+ DebitaV3AggregatorContract.changeOwner(newOwner);
+
+
+}
+```
+
+### Mitigation
+
+Use a different variable name for input param instead of `owner`
+
+```solidity
+function changeOwner(address _newOwner) public {
+ require(msg.sender == owner, "Only owner"); // checks against state variable
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = _newOwner; // proper assignment
+}
+```

+
+### Summary
+
+changeOwner function dosen't work properly
+
+### Root Cause
+
+1- The condition require(msg.sender == owner, "Only owner"); is incorrect because msg.sender is being checked against the parameter owner, which could be a different address. This does not verify the caller is the current contract owner.
+2-In the line `owner = owner;`, the local parameter owner shadows the state variable owner. This means you're assigning the parameter owner to itself instead of modifying the state variable

+# Owner can't be changed due to variable shadowing
+
+### Summary
+
+There are 3 Debita contracts that feature a `changeOwner()` function, allowing the current contract owner to designate a new owner up to 6 hours after the contract has been deployed:
+- [`buyOrderFactory.sol`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L186-L190)
+- [`AuctionFactory.sol`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L218-L222)
+- [`DebitaV3Aggregator.sol`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682-L686)
+
+```solidity
+contract DebitaV3Aggregator is ReentrancyGuard {
+ // ----- snip -----
+ address public owner;
+
+ // ----- snip -----
+ function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+```
+
+The issue here is that the storage variable `owner` cannot be changed due to variable shadowing.
+
+However, both the storage variable responsible for storing the address of the owner AND the `changeOwner()` parameter have the same name.
+
+
+
+
+### Root Cause
+
+The root cause of the issue arises from the fact that both the storage variable responsible for storing the address of the owner AND the `changeOwner()` parameter have the same name.
+
+This is called shadowing, more can be [read here](https://solstep.gitbook.io/solidity-steps/step-3/27-the-shadowing-effect).
+
+When called, the `changeOwner()` function creates its own scope, integrating the `owner` parameter to it.
+
+All the operations done on `owner` within the `changeOwner()` function will refer to the `owner` local variable (the parameter).
+
+This means `owner` will only be modified in the function and never affect the storage.
+
+### Internal pre-conditions
+
+None
+
+### External pre-conditions
+
+None
+
+### Attack Path
+
+None
+
+### Impact
+
+The contracts owner cannot be changed after being deployed.
+
+The `changeOwner()` function acts as a safeguard in case the `owner` has to be modified within 6 hours after the contracts have been deployed. It is safe to assume Debita will set the right `owner` at deploy time.
+Likelihood: **LOW**
+
+Since these contracts heavily rely on `owner` privileges to update core functionalities (fees, authorized oracles, authorized NFT collateral, pause the contract...) having the wrong `owner` at deploy time can be a long-term issue.
+Impact: **HIGH**
+
+Overall severity: **MEDIUM**
+
+### PoC
+
+The following PoC is using a simplified setup and `changeOwner()` function:
+
+```solidity
+pragma solidity ^0.8.20;
+
+import "forge-std/Test.sol";
+
+contract ShadowingTest is Test {
+ function testShadowing() public {
+ address user = makeAddr("user");
+
+ vm.startPrank(user);
+ OwnerShadowed ownerShadowed = new OwnerShadowed();
+
+ assertEq(ownerShadowed.owner(), address(0));
+ ownerShadowed.changeOwner(user);
+ assertEq(ownerShadowed.owner(), address(0));
+
+ vm.stopPrank();
+ }
+}
+
+contract OwnerShadowed {
+ address public owner;
+
+ function changeOwner(address owner) external {
+ require(msg.sender == owner, "Not owner");
+ owner = owner;
+ }
+}
+```
+
+### Mitigation
+
+Refactor the `changeOwner()` functions like such:
+
+```solidity
+function changeOwner(address _owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = _owner;
+}

+### Mitigation
+
+1. **Batching:** Instead of returning a large array of auction data in a single call, the protocol could implement functionality for smaller "batch" requests, so users can retrieve historical auctions incrementally with a certain cap on the maximum of length, not being depended on the `historicalAuctions` array length.
+
+2. **Pagination with Limits:** The protocol could impose a limit on the maximum number of auctions that can exist in `historicalAuctions` (e.g., capping the length at a certain number). Once the cap is reached, older auctions could be pruned or archived.

+# `DebitaChainLink` doesn't check for minAnswer/maxAnswer
+
+### Summary
+
+``DebitaChainLink`` Oracle doesn't validate for **minAnswer/maxAnswer**
+ChainLink aggregators have a built-in circuit breaker if the price of an asset goes outside of a predetermined price spectrum. The result is that if an asset experiences a huge drop in value (i.e LUNA crash) the price of the Oracle will continue to return the **minPrice** instead of the actual price of the asset.
+ since this project would be deployed on An ``EVM-Compatible network`` and they plan on interacting with
+> any ERC20 that follows exactly standard (e.g 18/6 decimals)
+
+which indicates that the protocol is expected to use BNB, ETH, AAVE,AVAX; so the isssue related to chainlink ``BNB/USD, ETH/USD, AAVE/USD, AVAX/USD`` is also Applicable here.
+Note that, according to the [docs](https://docs.sherlock.xyz/audits/judging/guidelines) of sherlock rules min/max check is considered a valid issue as long as :
+> Issues related to minAnswer and maxAnswer checks on Chainlink's Price Feeds are considered medium only if the Watson explicitly mentions the price feeds (e.g. USDC/ETH) that require this check.
+
+``AAVE/USD`` and ``AVAX/USD`` are example of tokens that return minAnswer on Arbitrum, and they are countless examples
+
+
+### Root Cause
+
+Not checking the ``minAnswer`` for the specific token, and reverting if that is what the oracle returned
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+The price of the asset drops below the minAnswer
+
+### Attack Path
+
+1. The price of the asset drops below the minAnswer
+2. A user creates a borrow offer using the asset as collateral at it's inflated price
+
+### Impact
+
+This would allow users continue creating borrow offers with collaterals having wrong prices backing up their loans.
+
+### PoC

+
+### Mitigation

+
+The address of the `aggregatorContract` contract in the `DebitaBorrowOffer-Factory` contract can be updated by the admin via the `setAggregatorContract` function below.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L201
+
+```solidity

+203: require(msg.sender == owner, "Only owner can set aggregator contract");
+204: aggregatorContract = _aggregatorContract;
+205: }
+```
+
+When the Borrow Offer is created and initialized, the current `aggregatorContract` address is passed in, as shown in Line 109 below. Assume that the current `aggregatorContract` address is $X$.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L109

+107:
+108: borrowOffer.initialize(
+109: aggregatorContract,
+110: msg.sender,
+111: _acceptedPrinciples,
+```
+
+The `aggregatorContract` address of $X$ will be cached within the Borrow Offer contract, as shown in Line 82 below.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L98

+66: address _aggregatorContract,
+..SNIP..
+81: ) public initializer {
+82: aggregatorContract = _aggregatorContract;
+83: isActive = true;
+```
+
+Assume at some point of time later, when the admin updates to the new aggregator address called $Y$.
+
+The issue is that all the existing borrow offers will still point to the invalid and outdated aggregator address of $X$ Instead of the updated $Y$. In addition, there is no function with the borrow offer contract to update the cached aggregator address to the updated $Y$.
+
+This issue also affects the following contracts and lending offers:
+
+- [`DebitaLendOfferFactory.sol`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L49) and [`DebitaLendOffer-Implementation.sol`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L18)
+
+When this issue occurs, all affected borrow offers are effectively useless and cannot be matched because when the Borrow Offer's `acceptBorrowOffer` function is executed by the new aggregator, the `onlyAggregator` modifier will always revert because it is still pointing to the outdated/invalid aggregator.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L137

+137: function acceptBorrowOffer(
+138: uint amount
+139: ) public onlyAggregator nonReentrant onlyAfterTimeOut {
+```
+
+When this issue occurs, all affected lending offers are effectively useless and cannot be matched because when the Lending Offer's `acceptLendingOffer` function is executed by the new aggregator, the `onlyAggregator` modifier will always revert because it is still pointing to the outdated/invalid aggregator.

+111: ) public onlyAggregator nonReentrant onlyAfterTimeOut {
+```
+
+### Impact
+
+Medium. Breaks core contract functionality and renders all existing lending and borrow order contracts useless
+
+Note that due to the newly updated Sherlock's judging rules (shown below), issues that the admin might unknowingly cause when updating a state variable, such as the issue described here, are considered valid.
+
+> **(External) Admin trust assumptions**: ..SNIP..
+>
+> Note: if the (external) admin will unknowingly cause issues, it can be considered a valid issue.

+Multiple instances of the issues issue were found across the codebase.
+
+**Instance 1 - Borrow Offer**
+
+The `borrowInformation.availableAmount` is reduced by `amount` in the memory at Line 147 below. However, the update is not written back to the storage. As a result, the borrow order has an infinite amount of collateral since it never gets reduced.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L147
+
+```solidity

+138: uint amount

+140: BorrowInfo memory m_borrowInformation = getBorrowInfo();
+141: require(

+143: "Amount exceeds available amount"
+144: );
+145: require(amount > 0, "Amount must be greater than 0");
+146:
+147: borrowInformation.availableAmount -= amount;
+```
+
+Assume that at $T0$ Bob's borrow order has `borrowInformation.availableAmount` = 1000 USDC and 1000 USDC residing on his borrow order contract.
+
+At $T1$, an aggregator matched Bob's borrow order and `acceptBorrowOffer(300 USDC)` is executed. Thus, 300 USDC will be transferred out from Bob's borrowing order to the Loan contract to be held as collateral. The `borrowInformation.availableAmount` will remain at 1000 USDC because the update is not saved to the storage. After the transaction, the state will be as follows:
+
+- `borrowInformation.availableAmount` = 1000 USDC
+- USDC balance on Bob's borrow order = 700 USDC (1000 - 300)
+
+At $T2$, Bob wants to cancel his borrow order to withdraw his remaining USDC in his borrow order. When the `cancelOffer()` is executed, `availableAmount` at Line 190 below will be 1000 USDC, and the code will attempt to transfer 1000 USDC at Line 210 below. However, due to insufficient funds (1000USDC vs 700USDC), the transfer will revert. Thus, Bob's assets are stuck in the order.

+
+**Instance 2 - Lend Offer**
+
+The `lendInformation.availableAmount` is reduced by `amount` in the memory at Line 120 below. However, the update is not written back to the storage. As a result, the lending order has an infinite amount of collateral since it never gets reduced.

+119:
+120: lendInformation.availableAmount -= amount;
+```
+

+
+The following is the extract from the [contest's README](https://github.com/sherlock-audit/2024-11-debita-finance-v3-xiaoming9090?tab=readme-ov-file#q-if-you-are-integrating-tokens-are-you-allowing-only-whitelisted-tokens-to-work-with-the-codebase-or-any-complying-with-the-standard-are-they-assumed-to-have-certain-properties-eg-be-non-reentrant-are-there-any-types-of-weird-tokens-you-want-to-integrate):
+
+> Q: If you are integrating tokens, are you allowing only whitelisted tokens to work with the codebase or any complying with the standard? Are they assumed to have certain properties, e.g. be non-reentrant? Are there any types of [weird tokens](https://github.com/d-xo/weird-erc20) you want to integrate?
+> - Fee-on-transfer tokens will be used only in TaxTokensReceipt contract
+
+Thus, Fee-on-Transfer (FOT) tokens are supported within the protocol as long as it is wrapped within the `TaxTokensReceipt contract`.
+
+Assume that the FOT has a 10% transfer tax. Thus, if one transfers 100 FOT, the issuer will collect 10 FOT, and the recipient will receive 90 FOT.
+
+Assume that Bob will create a borrow or lender offer using 100 FOT. In this case, he will call `TaxTokensReceipt.deposit(100 FOT)`.
+
+The `balanceBefore` at Line 60 is zero at this point. Next, Line 61 below will attempt to pull 100 FOT from Bob's wallet. However, due to the 10% transfer tax, only 90 FOT will be transferred to the `TaxTokensReceipt` contract. Thus, the `difference` at Line 68 will be 90 FOT.
+
+Next, the `require(difference >= amount, "TaxTokensReceipts: deposit failed");` check will be executed. Since `difference` will always be lesser than `amount` due to the tax, this `require` statement will always revert. As a result, there is no way for anyone to wrap their FOT within the `TaxTokensReceipt` to be used within the protocol.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L59

+59: function deposit(uint amount) public nonReentrant returns (uint) {

+61: SafeERC20.safeTransferFrom(

+63: msg.sender,
+64: address(this),

+72: _mint(msg.sender, tokenID);
+73: emit Deposited(msg.sender, amount);
+74: return tokenID;
+75: }
+```
+
+### Impact
+
+Medium. It meets the following requirements of Medium severity.
+
+- Breaks core contract functionality since the protocol is designed to support FOT by wrapping it within the `TaxTokensReceipt`. However, due to this bug, FOT cannot be used within the protocol.
+- Rendering the contract useless. The `TaxTokensReceipt` is effectively useless since no one can deposit FOT token.

+**Instance 1 - veAERO NFT receipt**
+
+Bob owns a veAERO NFT that has a locked amount of 1000 AERO. He deposited it into the `veNFTAerodrome` contract via the [`veNFTAerodrome.deposit()`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/veNFTS/Aerodrome/Receipt-veNFT.sol#L63) function and minted with Debita's veAERO NFT receipt.
+
+Bob negotiated with Alice and sold the veAERO NFT receipt to her. Alice made the payment and Bob transferred the veAERO NFT receipt to her.
+
+However, right before the transfer transaction, Bob front-run the transfer transaction and executed [`veNFTVault.withdraw`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/veNFTS/Aerodrome/veNFTAerodrome.sol#L86) function to withdraw his veAERO NFT from the veAERO NFT receipt. When the transfer transaction is executed, an empty veAERO NFT receipt will be transferred to Alice, and she end up holding a worthless veAERO NFT receipt.
+
+**Instance 2 - TaxTokensReceipt**
+
+The TaxTokensReceipt receipt NFT is subjected to the same issue as it also allows the owner to withdraw the assets within the receipt via the [`TaxTokensReceipt.withdraw`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L78) function to carry out an attack similar to the one described in Instance 1.

+
+The protocol has implemented the `veNFTAerodrome` NFT receipt contract to allow users to deposit their veAERO NFT into this contract and a `veNFTAerodrome` NFT receipt will then be minted to the users.
+
+The `veNFTAerodrome` NFT receipt will be used within the protocol during lending and borrowing.
+
+As the users are the managers of the `veNFTAerodrome` NFT receipt, it gives the users the ability to continue performing actions such as voting and claiming rewards via the veAERO NFT that they owned earlier, even though the `veNFTAerodrome` NFT receipt resides within the Loan address and does not reside in their wallet.
+
+From the [Aerodrome docs](https://aerodrome.finance/docs):
+
+> 1. **veAERO Voters** are rewarded (proportionally to locked amounts) for their votes with 100% of the protocol trading fees from the previous epoch and any additional voters incentives from the current epoch.
+
+The veAERO NFT allows users to claim two (2) kinds of rewards:
+
+1. Bribes/incentives
+2. Trading fee
+
+The following shows that on-chain [Aerodrome's Voter](https://basescan.org/address/0x16613524e02ad97eDfeF371bC883F2F5d6C480A5#code#L743) contract consists of `claimBribes` and `claimFees` functions, which allow users to claim Bribes/incentives and trading fees, respectively.
+
+https://basescan.org/address/0x16613524e02ad97eDfeF371bC883F2F5d6C480A5#code#L743
+
+```solidity
+ /// @notice Claim bribes for a given NFT.
+ /// @dev Utility to help batch bribe claims.
+ /// @param _bribes Array of BribeVotingReward contracts to collect from.
+ /// @param _tokens Array of tokens that are used as bribes.
+ /// @param _tokenId Id of veNFT that you wish to claim bribes for.
+ function claimBribes(address[] memory _bribes, address[][] memory _tokens, uint256 _tokenId) external;
+
+ /// @notice Claim fees for a given NFT.
+ /// @dev Utility to help batch fee claims.
+ /// @param _fees Array of FeesVotingReward contracts to collect from.
+ /// @param _tokens Array of tokens that are used as fees.
+ /// @param _tokenId Id of veNFT that you wish to claim fees for.
+ function claimFees(address[] memory _fees, address[][] memory _tokens, uint256 _tokenId) external;
+```
+
+However, the issue is that the `veNFTAerodrome` contract only implements a feature to claim bribes, but it is missing out on a feature to allow the users to claim the trading fee rewards within their veAERO NFT. Thus, users are unable to claim the trading fee rewards, leading to a loss of assets for the users.

+**Instance 1**
+
+The Aerodrome's [veAERO NFT](https://basescan.org/token/0xebf418fe2512e7e6bd9b87a8f0f294acdc67e6b4#code) can be an unmanaged veNFT OR managed veNFT. A managed veAERO NFT (also called (m)veAERO NFT) operates like a vault that allows users to deposit and withdraw their unmanaged veNFT into the managed veNFT via the [`Voter.depositManaged`](https://basescan.org/address/0x16613524e02ad97eDfeF371bC883F2F5d6C480A5#code#L1302) and [`Voter.withdrawManaged`](https://basescan.org/address/0x16613524e02ad97eDfeF371bC883F2F5d6C480A5#code#L1309) functions. Thus, the locked amount within the (m)veAERO NFT can increase or decrease.
+
+Bob, the malicious user, owns a (m)veAERO NFT and locks his unmanaged veNFT worth 1,000,000 AERO within it. He then converts it into an NFT receipt and uses it as collateral in his borrow offer. The borrow offer intends to exchange borrow 1,000,000 USDC at the price/ratio of 1 AERO = 1 USDC.
+
+Bob then matches his borrow order against other users' lending orders via the permissionless [`DebitaV3Aggregator.matchOffersV3`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274) function himself. A new Loan contract is created, and 1,000,000 USDC is sent to Bob's wallet, and the (m)veAERO NFT is transferred into the Loan contract.
+
+Next, Bob calls the [`Voter.withdrawManaged`](https://basescan.org/address/0x16613524e02ad97eDfeF371bC883F2F5d6C480A5#code#L1309) function to withdraw his unmanaged veNFT, which is worth 1,000,000 AERO, from the (m)veAERO NFT. As a result, the (m)veAERO NFT collateral within the Loan becomes worthless now.
+
+Bob now holds 1,000,000 USDC and 1,000,000 AERO.
+
+Bob defaults on the Loan, and the (m)veAERO NFT will be auctioned. Since the (m)veAERO NFT is worthless, no one will purchase it, and the lender will not get any funds back and will lose 1,000,000 USDC
+
+**Instance 2**
+
+Any mechanism that relies on NFT receipt will be vulnerable to such an issue by exploiting the managed veNFT.
+
+Another instance that is affected by a similar issue is the [`BuyOrder.sellNFT`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L92) function, where the NFT receipt with managed veNFT is placed within a buy order and put up for sale. Once the NFT receipt is sold, the seller can proceed to withdraw all the locked amount within the NFT receipt, leaving the buyer with a worthless NFT receipt. Since the root cause is similar, the attack path will be omitted for brevity.

+
+Within the `DebitaV3Aggregator.matchOffersV3` function, the price is calculated using USD-nominated pair with 8 decimal precision. If the price returned from the Pyth oracle is not 8 decimals, the calculation will be incorrect, which lead to the ratio/price to be inflated or deflated.
+
+Following is the extract from [Pyth's documentation](https://api-reference.pyth.network/price-feeds/evm/getPriceNoOlderThan), which shows the price data returned from Pyth oracle. The price data consists of the exponent (or decimal) of the price returned.
+
+> The price object contains the following fields:
+>
+> 1. `price`: The latest price of the price feed.
+> 2. `conf`: The confidence level of the price feed.
+> 3. `expo`: The exponent of the price feed.
+> 4. `publishtime`: The time when the price feed was last updated.
+>
+> Sample `price` object:
+>
+> ```
+> {
+> price: 123456789n,
+> conf: 180726074n,
+> expo: -8,
+> publishTime: 1721765108n
+> }
+> ```
+>
+> The `price` above is in the format of `price * 10^expo`. So, the `price` in above mentioned sample represents the number `123456789 * 10(-8) = 1.23456789` in this case.
+
+However, the issue is that the `DebitaPyth` assumes that the price returned from Pyth is always 8 decimals. This assumption is invalid.
+
+For instance, the price of BTT tokens (id = Crypto.BTT/USD (0x097d687437374051c75160d648800f021086bc8edf469f11284491fda8192315)) returned by Pyth Oracle is in 10 decimals precision.
+
+```solidity
+{
+ price: 8851n,
+ conf: 39n,
+ expo: -10,
+ publishTime: 1727961560n
+}
+```
+
+As a result, the calculated price/ratio will be inflated or deflated. When the price/ratio of collateral/principle tokens is incorrect, more or less collateral/principle tokens within the lending/borrow offers will be matched, resulting in a loss for the lender or borrower.
+
+For instance, if the collateral price within the borrow offer is inflated, the protocol will assume that the borrow offer contains collateral that is worth much more than expected and allow them to borrow more principle than expected from the lenders, resulting in a loss for the affected lenders.

+However, the issue is that within the `deleteBorrowOrder` function, it does not set `isBorrowOrderLegit[address(borrowOffer)] = false;` after deleting
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L162

+
+As a result, within the Debita contracts, they will assume that the deleted borrow order is still valid.
+
+### Impact
+
+Within the Debita contracts, they will assume that the deleted borrow order is still valid, which might lead to unexpected errors. For instance, the borrow order is still considered as valid within the `DebitaV3Aggregator`'s matching feature, and buy order feature.

+Assume that Bob creates a borrow offer. When the Loan is matched, the `Aggregator(AggregatorContract).feePerDay()` is equal to 10 (0.1%), and the `borrowInfo.duration` is 8 days. Thus, the `percentage` will be equal to 80 (0.1% * 8 days = 0.8%).
+
+At $T0$, assume that Bob should receive 1,000,000 USDC as principle tokens from the Loan (`amountPerPrinciple[i] = 1000 USDC`). In this case, he would need to pay a fee of 8000 USDC (1,000,000 * 0.8% ) as the fee, and he will only receiveve 992,000 USDC
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L544
+
+```solidity
+File: DebitaV3Aggregator.sol
+391: uint percentage = ((borrowInfo.duration * feePerDay) / 86400);
+..SNIP..
+543: // calculate fees --> msg.sender keeps 15% of the fee for connecting the offers
+544: uint feeToPay = (amountPerPrinciple[i] * percentage) / 10000;
+545: uint feeToConnector = (feeToPay * feeCONNECTOR) / 10000;
+546: feePerPrinciple[i] = feeToPay;
+```
+
+At $T1$, Bob decided to extend the loan via the `extendLoan()` function. However, at this point, the `Aggregator(AggregatorContract).feePerDay()` has been updated to 5 (0.05%).
+
+Thus, the `PorcentageOfFeePaid` computed at Line 571 below equal to 0.4% (0.05% * 8 days = 0.4%).
+
+The first issue here is that earlier at $T0$, Bob actually paid 0.8% (8000 USDC) worth of fee. However, now, the protocol wrongly assumes that Bob has only paid 0.4% worth of the fee, which is incorrect.
+
+Assume that the `offer.maxDeadline` is 10 days. Thus, the `feeOfMaxDeadline` calculated at Line 602 will be 0.5% (10 days * 0.05 = 0.5%). With the new duration of 10 days, the protocol expects Bob to pay 0.5% of the offer's principle amount (1,000,000), which is equal to 5000 USDC (1,000,000 * 0.5% =5,000).
+
+```solidity
+misingBorrowFee = feeOfMaxDeadline - PorcentageOfFeePaid
+misingBorrowFee = 0.5% - 0.4% = 0.1%
+```
+
+The protocol determined that Bob still needs to pay an additional of 0.1% worth of fee, which is equal to 1000 USDC. The protocol will transfer 1000 USDC from Bob's wallet to be paid as fee.
+
+However, the math is incorrect. Protocol has determined that Bob is subjected to a 5000 USDC fee after extending the loan with a longer duration. Bob has already paid 8000 USDC earlier at $T0$. Thus, Bob has already paid more than 5000 USDC, yet the protocol proceeds to charge an additional fee of 1000 USDC. At the end, with the computed fee of 5000 USDC, Bob ends up paying 9000 USDC (8000 + 1000).
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L613
+
+```solidity
+File: DebitaV3Loan.sol
+544:
+545: // function to extend the loan (only the borrower can call this function)
+546: // extend the loan to the max deadline of each offer
+547: function extendLoan() public {
+..SNIP..
+567: // calculate fees to pay to us
+568: uint feePerDay = Aggregator(AggregatorContract).feePerDay();
+..SNIP..
+571: uint PorcentageOfFeePaid = ((m_loan.initialDuration * feePerDay) /
+572: 86400);
+..SNIP..
+597: uint misingBorrowFee;
+598:
+599: // if user already paid the max fee, then we dont have to charge them again
+600: if (PorcentageOfFeePaid != maxFee) {
+601: // calculate difference from fee paid for the initialDuration vs the extra fee they should pay because of the extras days of extending the loan. MAXFEE shouldnt be higher than extra fee + PorcentageOfFeePaid
+602: uint feeOfMaxDeadline = ((offer.maxDeadline * feePerDay) /
+603: 86400);
+604: if (feeOfMaxDeadline > maxFee) {
+605: feeOfMaxDeadline = maxFee;
+606: } else if (feeOfMaxDeadline < feePerDay) {
+607: feeOfMaxDeadline = feePerDay;
+608: }
+609:
+610: misingBorrowFee = feeOfMaxDeadline - PorcentageOfFeePaid;
+611: }
+612: uint principleAmount = offer.principleAmount;
+613: uint feeAmount = (principleAmount * misingBorrowFee) / 10000;
+```
+
+The previous example describes a scenario where `Aggregator(AggregatorContract).feePerDay()` is decreased. However, if the `Aggregator(AggregatorContract).feePerDay()` is increased, the opposite will happen. In this case, the protocol will be the victim instead of the users, and the protocol will undercharge the fee and assume that Bob has already paid a certain amount of fee, while in reality did not.
+
+### Impact
+
+High. Loss of assets. In the above scenario, Bob ends up paying an additional 1000 USDC while, in fact, this is not required because he has already paid more than sufficient fees earlier. Alternatively, the protocol might undercharge the users.
+
+Note that due to the newly updated Sherlock's judging rules (shown below), issues that the admin might unknowingly cause when updating a state variable, such as the issue described here, are considered valid.
+
+> **(External) Admin trust assumptions**: ..SNIP..
+>
+> Note: if the (external) admin will unknowingly cause issues, it can be considered a valid issue.
+>
+> > Example: Admin sets fee to 20%. This will cause liquidations to fail in case the utilization ratio is below 10%, this can be Medium as the admin is not aware of the consequences of his action.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Consider caching the actual fee used at the point of time the Loan/Offer is created and matched within the `DebitaV3Aggregator.sol.matchOffersV3` function instead of fetching it dynamically from the `AggregatorContract` contract.

+### Attack Path
+
+Following is the information about `MixOracle` extracted from the [Debita's documentation](https://debita-finance.gitbook.io/debita-v3/lending/oracles) for context:
+
+> To integrate a token without a direct oracle, a mix oracle is utilized. This oracle uses a TWAP oracle to compute the conversion rate between Token A and Token B. Token B must be supported on PYTH oracle, and the pricing pool should have substantial liquidity to ensure security.
+>
+> This approach enables us to obtain the USD valuation of tokens that would otherwise would be impossible.
+
+The following attempts to walk through how the MixOracle is used for reader understanding before jumping into the issue.
+
+WFTM token is supported on Pyth Oracle via the `WFTM/USD` price feed, but there is no oracle in Fantom Chain that supports EQUAL token. Thus, the `MixOracle` can be leveraged to provide the price of the EQUAL token even though no EQUAL price oracle exists. A pricing pool with substantial liquidity that consists of EQUAL token can be used here.
+
+Let's use the WFTM/EQUAL pool (EQUALPAIR = [0x3d6c56f6855b7Cc746fb80848755B0a9c3770122](https://ftmscan.com/address/0x3d6c56f6855b7cc746fb80848755b0a9c3770122)) from Equalizer within the test script for illustration.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/test/fork/Loan/ltv/Tarot-Fantom/OracleTarotUSDCEQUAL.t.sol#L138
+
+```solidity
+File: OracleTarotUSDCEQUAL.t.sol
+136: function testUSDCPrincipleAndEqualCollateral() public {
+137: createOffers(USDC, EQUAL);
+138: DebitaMixOracle.setAttachedTarotPriceOracle(EQUALPAIR);
+139: vm.warp(block.timestamp + 1201);
+140: int priceEqual = DebitaMixOracle.getThePrice(EQUAL);
+```
+
+The token0 and token1 of the WFTM/EQUAL pool are as follows as retrieved from the FTMscan:
+
+- token0 = [0x21be370D5312f44cB42ce377BC9b8a0cEF1A4C83](https://ftmscan.com/address/0x21be370D5312f44cB42ce377BC9b8a0cEF1A4C83) = WFTM
+
+- token1 = [0x3Fd3A0c85B70754eFc07aC9Ac0cbBDCe664865A6](https://ftmscan.com/address/0x3Fd3A0c85B70754eFc07aC9Ac0cbBDCe664865A6) = EQUAL
+
+In this case, the price returned from the pool will be computed by EQUAL divided by WFTM. So, the price of EQUAL per WFTM is provided by the pool.
+
+```solidity
+Equalizer Pool's getPriceCumulativeCurrent = reserve1/reserve0 = token1/token0 = EQUAL/WFTM
+```
+
+When configuring the `MixOracle` to support EQUAL token, the `setAttachedTarotPriceOracle` will be executed, and the pool address ([0x3d6c56f6855b7Cc746fb80848755B0a9c3770122](https://ftmscan.com/address/0x3d6c56f6855b7cc746fb80848755b0a9c3770122)) will be passing in via the `uniswapV2Pair` parameter. In this case, the `MixOracle` will return the price of the EQUAL (token1) token when the `MixOracle.getThePrice(EQUAL)` function is executed within another part of the protocol.
+
+```solidity
+AttachedPricedToken[token1] = token0;
+AttachedPricedToken[EQUAL] = WFTM;
+```
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/MixOracle/MixOracle.sol#L72
+
+```solidity
+File: MixOracle.sol
+72: function setAttachedTarotPriceOracle(address uniswapV2Pair) public {
+73: require(multisig == msg.sender, "Only multisig can set price feeds");
+74:
+75: require(
+76: AttachedUniswapPair[uniswapV2Pair] == address(0),
+77: "Uniswap pair already set"
+78: );
+79:
+80: address token0 = IUniswapV2Pair(uniswapV2Pair).token0();
+81: address token1 = IUniswapV2Pair(uniswapV2Pair).token1();
+82: require(
+83: AttachedTarotOracle[token1] == address(0),
+84: "Price feed already set"
+85: );
+86: DebitaProxyContract tarotOracle = new DebitaProxyContract(
+87: tarotOracleImplementation
+88: );
+89: ITarotOracle oracle = ITarotOracle(address(tarotOracle));
+90: oracle.initialize(uniswapV2Pair);
+91: AttachedUniswapPair[token1] = uniswapV2Pair;
+92: AttachedTarotOracle[token1] = address(tarotOracle);
+93: AttachedPricedToken[token1] = token0;
+94: isFeedAvailable[uniswapV2Pair] = true;
+95: }
+```
+
+The issue is that the `MixOracle` relies on the position of token0 and token1 in the pool that cannot be controlled. Within the pool (Equalizer or Uniswap Pool), the position of token0 and token1 is pre-determined and sorted by the token's address (smaller address will always be token0)
+
+However, the position of the token in the `setAttachedTarotPriceOracle `function is hardcoded. For instance, the keys of the `AttachedUniswapPair`, `AttachedTarotOracle`, `AttachedPricedToken` mapping are all hardcoded to `token1`.
+
+Assume that the protocol wants to create another `MixOracle` to support another token called $Token_X$ that does not have any oracle on Fantom. However, this token to be supported is located in the position of `token0` instead of `token1` in the pool. Thus, because the `MixOracle` is hardcoded to always use only `token1`, there is no way to support this $Token_X$ even though a high liquidity pool that consists of $Token_X$ exists on Fantom.
+
+The `MixOracle` is supposed to work in this scenario, but due to hardcoded position, it cannot supported. Thus, the `MixOracle` is broken in this scenario.
+
+### Impact
+
+Medium. Breaks core contract functionality. Oracle is a core feature in a protocol.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Consider not hardcoding the position (`token1`) as the key of the mapping used within `MixOracle`. Instead, allow the deployer to specify which token (`token0` or `token1`) the `MixOracle` is supposed to support.

+
+Within the `DebitaV3Aggregator.matchOffersV3` function, the price is calculated using USD-nominated pair with 8 decimal precision. If the price returned from the Chainlink oracle is not 8 decimals, the calculation will be incorrect, which lead to the ratio/price to be inflated or deflated.

+```
+
+Upon inspecting the `DebitaChainlink.getThePrice` function, it was found that the code always assumes that the price returned from Chainlink Oracle is always 8 decimals. However, this assumption is wrong. There are some USD-nominated pair, such as AMPL/USD, that report prices using 18 decimals. Refer to this [article](https://medium.com/cyfrin/chainlink-oracle-defi-attacks-93b6cb6541bf#87fc)'s "Assuming Oracle Price Precision" section foe more details.
+
+As a result, the calculated price/ratio will be inflated or deflated. When the price/ratio of collateral/principle tokens is incorrect, more or less collateral/principle tokens within the lending/borrow offers will be matched, resulting in a loss for the lender or borrower.
+
+For instance, if the collateral price within the borrow offer is inflated, the protocol will assume that the borrow offer contains collateral that is worth much more than expected and allow them to borrow more principle than expected from the lenders, resulting in a loss for the affected lenders.

+> Q: If you are integrating tokens, are you allowing only whitelisted tokens to work with the codebase or any complying with the standard? Are they assumed to have certain properties, e.g. be non-reentrant? Are there any types of [weird tokens](https://github.com/d-xo/weird-erc20) you want to integrate?
+>
+> - Fee-on-transfer tokens will be used only in TaxTokensReceipt contract
+
+Thus, Fee-on-Transfer (FOT) tokens are supported within the protocol as long as it is wrapped within the `TaxTokensReceipt contract`.
+
+The protocol has a buy order feature. Following is the extract from the [documentation](https://debita-finance.gitbook.io/debita-v3/marketplace/limit-order)
+
+> 'Buy Order' feature on Debita V3 Marketplace. This concept allows users to create buy orders, providing a mechanism for injecting liquidity to purchase specific receipts at predetermined ratios. This development ensures that receipt holders can access immediate liquidity upon sale.
+
+Assume Bob has 10,000 FOT and wants to use it to purchase veAERO NFT receipt. Thus, he has to wrap the 10,000 FOT into protocol `TaxTokensReceipt` receipt NFT and create a buy order.
+
+However, it was found that the `buyOrderFactory.createBuyOrder` function at Line 101 uses the ERC20's transfer, which will not be able to transfer the `TaxTokensReceipt` receipt NFT into the buy order, and a revert will occur. In this case, the buy order feature is broken.

+
+All Fee-on-Transfer (FOT) tokens have to be wrapped with the `TaxTokensReceipt` NFT to be used within the protocol.
+
+Bob has 10,000 FOT. Thus, he deposits 10,000 FOT into the `TaxTokensReceipt` contract via the [`TaxTokensReceipts.deposit`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L59) function, and a `TaxTokensReceipt` NFT representing 10,000 FOT will be minted for Bob.
+
+Bob creates a new borrow offer and uses the newly minted `TaxTokensReceipt` NFT as collateral.
+
+Bob's borrow offer is matched against a number of lending offers, and a new Loan contract is created. The `TaxTokensReceipt` NFT within Bob's borrow offer will be transferred to the newly created Loan contract to be held as collateral.
+
+Bob defaults on the Loan. As a result, a new auction is created to auction off the `TaxTokensReceipt` NFT held within the Loan contract to repay the lender. Line 93 below shows that the `TaxTokensReceipt` NFT will be transferred into the newly created Auction contract.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L93
+
+```solidity
+File: AuctionFactory.sol
+68: function createAuction(
+..SNIP..
+75: ) public returns (address) {
+76: // check if aggregator is set
+77: require(aggregator != address(0), "Aggregator not set");
+78:
+79: // initAmount should be more than floorAmount
+80: require(_initAmount >= _floorAmount, "Invalid amount");
+81: DutchAuction_veNFT _createdAuction = new DutchAuction_veNFT(
+..SNIP..
+90: );
+91:
+92: // Transfer veNFT
+93: IERC721(_veNFTAddress).safeTransferFrom(
+94: msg.sender,
+95: address(_createdAuction),
+96: _veNFTID,
+97: ""
+98: );
+```
+
+Buyer will call the `Auction.buyNFT` function to purchase the auctioned NFT. When the NFT is sold, Line 148 within the function will attempt to transfer the `TaxTokensReceipt` NFT held within the Auction contract to the buyer.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L148
+
+```solidity
+File: Auction.sol
+109: function buyNFT() public onlyActiveAuction {
+..SNIP..
+148: IERC721 Token = IERC721(s_CurrentAuction.nftAddress);
+149: Token.safeTransferFrom(
+150: address(this),
+151: msg.sender,
+152: s_CurrentAuction.nftCollateralID
+153: );
+```
+
+However, the transfer will always revert because the transfer function has been overwritten, as shown below. The transfer function has been overwritten to only allow the transfer to proceed if the `to` or `from` involves the following three (3) contracts:
+
+1. Borrow Order Contract
+2. Lend Order Contract
+3. Loan Contract
+
+Since neither the Auction contract nor the buyer is the above three contracts, the transfer will always fail. Thus, there is no way for the collateral to be auctioned off, and the collateral will be stuck. As a result, lenders will not get repaid, leading to a loss of assets.

+The following is the extract from the [contest's README](https://github.com/sherlock-audit/2024-11-debita-finance-v3-xiaoming9090?tab=readme-ov-file#q-if-you-are-integrating-tokens-are-you-allowing-only-whitelisted-tokens-to-work-with-the-codebase-or-any-complying-with-the-standard-are-they-assumed-to-have-certain-properties-eg-be-non-reentrant-are-there-any-types-of-weird-tokens-you-want-to-integrate):
+
+> Q: If you are integrating tokens, are you allowing only whitelisted tokens to work with the codebase or any complying with the standard? Are they assumed to have certain properties, e.g. be non-reentrant? Are there any types of [weird tokens](https://github.com/d-xo/weird-erc20) you want to integrate?
+>
+> - Fee-on-transfer tokens will be used only in TaxTokensReceipt contract
+
+Thus, Fee-on-Transfer (FOT) tokens are supported within the protocol as long as it is wrapped within the `TaxTokensReceipt contract`.
+
+Assume that the FOT has a 10% transfer tax. Thus, if one transfers 100 FOT, the issuer will collect 10 FOT, and the recipient will receive 90 FOT.
+
+Assume that Bob will create a borrow or lender offer using 100 FOT. In this case, he will call `TaxTokensReceipt.deposit(100 FOT)`.
+
+The `balanceBefore` at Line 60 is zero at this point. Next, Line 61 below will attempt to pull 100 FOT from Bob's wallet. However, due to the 10% transfer tax, only 90 FOT will be transferred to the `TaxTokensReceipt` contract. Thus, the `difference` at Line 68 will be 90 FOT.
+
+However, the issue is that in Line 71, the NFT's `tokenAmountPerID` is set to `amount`(100 FOT) instead of `difference` (90 FOT). Thus, the NFT's `lockedAmount` will show 100 FOT, while in reality, there is only 90 FOT residing in the NFT.
+
+This is a major issue because the `TaxTokensReceipt` NFT is used as collateral within the borrow offer. Thus, the collateral within the borrow offer will be inflated. As a result, the protocol will assume that the borrow offer contains collateral that is worth much more than expected and allow them to borrow more principle than expected from the lenders, resulting in a loss for the affected lenders.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L71
+
+```solidity
+File: TaxTokensReceipt.sol
+58: // expect that owners of the token will excempt from tax this contract
+59: function deposit(uint amount) public nonReentrant returns (uint) {
+60: uint balanceBefore = ERC20(tokenAddress).balanceOf(address(this));
+61: SafeERC20.safeTransferFrom(
+62: ERC20(tokenAddress),
+63: msg.sender,
+64: address(this),
+65: amount

+72: _mint(msg.sender, tokenID);
+73: emit Deposited(msg.sender, amount);
+74: return tokenID;
+75: }
+```
+
+The second major issue due to this bug is that users will be unable to withdraw their assets from the `TaxTokensReceipt`.
+
+`tokenAmountPerID` is set to 100 FOT, while in reality, there is only 90 FOT residing in the NFT. In this case, when Line 87 is executed, the transfer amount will be 100 FOT, which will result in a revert due to insufficient FOT. Thus, users cannot withdraw their 90 FOT under any circumstance.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L87

+

+The price data returned from Pyth consists of the confidence interval. Refer to the Pyth documentation [here](https://docs.pyth.network/price-feeds/best-practices#confidence-intervals) and [here](https://www.pyth.network/blog/what-is-confidence) for more details.
+
+However, the `DebitaPyth` oracle was found not performing any validation against the returned confidence interval. As a result, prices that are extremely uncertain and might deviate significantly from the actual market price could be used with the protocol.
+
+As a result, the calculated price/ratio will be inflated or deflated. When the price/ratio of collateral/principle tokens is incorrect, more or less collateral/principle tokens within the lending/borrow offers will be matched, resulting in a loss for the lender or borrower.
+
+For instance, if the collateral price within the borrow offer is inflated, the protocol will assume that the borrow offer contains collateral that is worth much more than expected and allow them to borrow more principle than expected from the lenders, resulting in a loss for the affected lenders.

+
+If Bob extends a loan, he will need to pay 10% duration of the interest of all the extended offers within the loan. Assume that during the extension, Bob pay $X$ principle tokens as interest. The collected $X$ principle tokens interest are added to `loanData._acceptedOffers[i].interestToClaim` state variable and store within the Loan contract.
+
+Assume that Bob defaulted on the loan.
+
+In this case, Alice, who is the owner of the Loan will execute the `claimCollateralAsLender` function to claim all the collateral stored within the loan. After the `claimCollateralAsLender` transaction is executed, Alice's lender NFT will immediately be burned, as per Line 349 below.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L349
+
+```solidity
+File: DebitaV3Loan.sol
+340: function claimCollateralAsLender(uint index) external nonReentrant {
+341: LoanData memory m_loan = loanData;
+342: infoOfOffers memory offer = m_loan._acceptedOffers[index];
+343: IOwnerships ownershipContract = IOwnerships(s_OwnershipContract);
+344: require(
+345: ownershipContract.ownerOf(offer.lenderID) == msg.sender,
+346: "Not lender"
+347: );
+348: // burn ownership
+349: ownershipContract.burn(offer.lenderID);
+```
+
+Next, Alice wants to claim the interest. Thus, she calls the `claimDebt` function, thinking that she can claim the interest. The `claimDebt` function will internally call the `claimInterest` function to claim $X$ principle tokens collected earlier as interest fees.
+
+However, since Alice's lender NFT is already burned, the check at Line 275 below will always revert.
+
+Thus, Alice cannot claim the interest anymore, and the interest is stuck within the Loan contract forever.

+Assume Bob's has a borrow order with a veAERO NFT with 10,000,000 AERO worth of locked amount.
+
+Note that for borrow order with a NFT as its collateral, the order has to be completely matched within a single Loan, which is enforced via the check at Line 565 below within the `DebitaV3Aggregator.matchOffersV3` function. This means that you cannot break the borrow order into multiple Loans when the borrow order's collateral is NFT.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L565
+
+```solidity
+File: DebitaV3Aggregator.sol
+274: function matchOffersV3(
+..SNIP..
+562: // if collateral is an NFT, check if the amount of collateral is within the limits
+563: // it has a 2% margin to make easier the matching, amountOfCollateral is the amount of collateral "consumed" and the valuableAssetAmount is the underlying amount of the NFT
+564: if (borrowInfo.isNFT) {
+565: require(
+566: amountOfCollateral <=
+567: (borrowInfo.valuableAssetAmount * 10200) / 10000 &&
+568: amountOfCollateral >=
+569: (borrowInfo.valuableAssetAmount * 9800) / 10000,
+570: "Invalid collateral amount"
+571: );
+572: }
+```
+
+Due to the extremely high value of the borrow order, a total of 50 lend orders are needed to fulfill this specific borrow order within a single Loan. Per Lines 289 and 290 of the `DebitaV3Aggregator.matchOffersV3` function, up to 100 lend orders are supported. Thus, it is not an issue to have 50 lender orders.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L290
+
+```solidity

+284: // Add count
+285: loanID++;
+286: DBOImplementation.BorrowInfo memory borrowInfo = DBOImplementation(
+287: borrowOrder
+288: ).getBorrowInfo();
+289: // check lendOrder length is less than 100
+290: require(lendOrders.length <= 100, "Too many lend orders");
+```
+
+After matching all the 50 lender orders against Bob's borrow order, a new Loan contract will be created.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L585
+

+599: offers,
+600: s_OwnershipContract,
+601: feeInterestLender,
+602: feeAddress
+603: );
+```
+
+However, the issue is that when the Loan contract is created, there is a check at Line 156 below. In this case, the check will revert because the number of lend offers exceeds 30. As a result, Bob's borrow order cannot be matched due to revert.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L156

+
+### Impact

+The `feeAmount` at Line 120 below might round down to zero if the `amount` or `sellFee()` is low.

+
+### External pre-conditions

+
+### Attack Path
+
+The formula for calculating the floor amount of the auction is as follows:
+
+```solidity
+floorAmount = FloorPricePercentage * receiptInfo.lockedAmount
+```
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L139
+
+```solidity
+File: AuctionFactory.sol
+139: function getLiquidationFloorPrice(
+140: uint initAmount
+141: ) public view returns (uint) {
+142: return (initAmount * FloorPricePercentage) / 10000;
+143: }
+```
+
+The valid range of `FloorPricePercentage` is from 5% to 30%, as per [here](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L192). Assume that it is set to 30% at this point.
+
+The collateral to be auctioned, which is a veAERO NFT, has a locked amount of 10000 AERO. In this case, the floor price is set to 3000 AERO.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L470
+
+```solidity
+File: DebitaV3Loan.sol
+417: function createAuctionForCollateral(
+..SNIP..
+461: uint floorAmount = auctionFactory.getLiquidationFloorPrice(
+462: receiptInfo.lockedAmount
+463: );
+..SNIP..
+470: address liveAuction = auctionFactory.createAuction(
+471: m_loan.NftID,
+472: m_loan.collateral,
+473: receiptInfo.underlying,
+474: receiptInfo.lockedAmount,
+475: floorAmount,
+476: 864000
+477: );
+```
+
+When the user defaults, the auction will be created to sell the veAERO NFT, with a floor price of 3000 AERO.
+
+However, given the current market condition, the value of veAERO is unfavorable. No one is willing to purchase the veAERO NFT at the price of 3000 AERO. Thus, the market and its users are only willing to pay a maximum of 2500 AERO.
+
+> [!IMPORTANT]
+>
+> Note that even though the veAERO NFT has 10000 AERO locked amount, it does not mean that it is worth 10000 AERO. This means that buyers cannot simply perform an arbitrage by buying the veNFT for 9000 AERO, and immediately gain 1000 AERO in return.
+>
+> This is because the 10000 AERO within the veAERO NFT is usually locked up for four (4) years, and can only be retrieved after four years. The price of AERO four years from now will deviate from the present. Thus, the main value of holding the veAERO NFT is to claim the AERO incentive tokens and trading fee from Aerodrome. Thus, the price of veAERO NFT will mainly be determined by the number of AERO incentives and trading fee that can be claimed over the entire holding period.
+
+Thus, the veAERO NFT being auctioned at the existing floor price of 3000 AERO will not be sold under this market condition.
+
+As a result, the veAERO NFT will be stuck in the newly deployed auction contract with no way to update the floor price to a lower price, such as 2300 AERO, and restart the auction. There is also no way to cancel the auction and retrieve the veAERO NFT.
+
+Only the auction owner can update the floor price OR cancel the auction and retrieve the NFT within it. However, these actions can only be performed by the owner, who in this case is the `DebitaV3Loan` contract.
+
+However, the issue is that within the `DebitaV3Loan` contract, there is no feature that will trigger the [`Auction.editFloorPrice`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L192) or [`Auction.cancelAuction`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L168) functions.

+
+### Mitigation

+Provide the ability for the lenders or admin to update the floor price and restart the auction.

+Line 196 will mark Bob to indicate that he has claimed the 1000 XYZ incentive.
+
+Next, on Line 203 below, it will transfer 1000 XYZ incentive to Bob. However, due to a transfer error (which can occur due to many reasons, such as the XYZ token being temporarily paused by the XYZ protocol during an upgrade), the transfer did not occur and a `false` boolean is returned from the `XYZ.transfer` function, so Bob did not receive his 1000 XYZ.
+
+After the failure, Bob wants to try claiming the 1000 XYZ again. However, the check at Line 185 will revert because `claimedIncentives[Bob] ` is already marked as True. Thus, there is no way for Bob to claim the 1000 XYZ incentive.

+For context, it is the manager of the veNFT receipt who has the ability to vote on Aerodrome's gauges, not the owner of the veNFT receipt, as shown below.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/veNFTS/Aerodrome/Receipt-veNFT.sol#L120
+
+```solidity
+File: Receipt-veNFT.sol
+113: function voteMultiple(
+114: address[] calldata vaults,
+115: address[] calldata _poolVote,
+116: uint256[] calldata _weights
+117: ) external {
+118: for (uint i; i < vaults.length; i++) {
+119: require(
+120: msg.sender == veNFTVault(vaults[i]).managerAddress(),
+121: "not manager"
+122: );
+123: require(isVaultValid[vaults[i]], "not vault");
+124: veNFTVault(vaults[i]).vote(_poolVote, _weights);
+125: }
+126: }
+```
+
+When the collateral is the veNFT, if the borrower defaults, the veNFT receipt will either be sent directly to the lender or to the buyer from the auction. Either way, the consequences are the same.
+
+A malicious borrower, who is the existing manager of the veNFT receipt, can back-run the veNFT transfer transaction and vote in the gauges on Velo/Aerodrome to their advantage. For example, if the borrower is a liquidity provider (LP) for certain gauges, they can direct votes to those gauges, increasing the incentives they receive.
+
+Alternatively, the malicious manager may choose to grief the new owner of the veNFT receipt by voting for highly unprofitable gauges with minimal incentive rewards. This action would ensure the new owner receives little to no rewards in the next epoch, leading to a loss of funds.
+
+In either scenario, once the malicious manager votes in the current epoch, the new owner is unable to cast votes until the next epoch.

+
+Assuming that Alice creates a buy order to sell 1000 DAI (1000e18) in exchange for 2000 AERO (2000e18) at the ratio or price of `0.5 DAI per AERO`, which is equal to `5e17`.
+
+1. The first person, Bob, owns a veAERO with 1000 AERO underlying. He sold his veAERO NFT to the buy order and recieved 500 DAI in turn. Bob's veAERO NFT is transferred into the buy order.
+2. The second person, Charles, owns a veAERO with 1000 AERO underlying. He sold his veAERO NFT to the buy order and received 500 DAI in turn. Charles's veAERO NFT is transferred into the buy order.
+
+At this point, Alice's buy order can be considered fulfilled as she has sold off all her 1000 DAI, and received 1000 worth of AER0 (via 2 x veAERO NFT). 2 x veAERO NFT reside within the Buy Order.
+
+However, the issue is that there is no feature that allows Alice to withdraw the veAERO NFT from the Buy Order. Thus, the veAERO NFTs are stuck in the buy order.

+### Attack Path
+
+Assume that Bob creates a borrow offer with 10000 AERO as collateral to borrow 10000 USDC at the price/ratio of 1 AERO:1 USDC for simplicity's sake.
+
+Malicious aggregator (aggregator is a public role and anyone can match orders) can perform griefing attacks against Bob.
+
+The malicious aggregator can create many individual loans OR many loans with many offers within it, OR a combination of both. Each loan and offer will be small or tiny and consist of Bob's borrow order. This can be done because the protocol does not enforce any restriction on the minimum size of the loan or offer.
+
+As a result, Bob's borrow offer could be broken down into countless (e.g., thousands or millions) of loans and offers. As a result, Bob will not be able to keep track of all the loans and offers belonging to him and will have issues paying the debt or claiming collateral.
+
+This issue is also relevant to the lenders, and the impact is even more serious as lenders have to perform more actions against loans and offers, such as claiming debt, claiming interest, claiming collateral, or auctioning off defaulted collateral etc.
+
+In addition, it also requires lenders and borrowers to pay a significant amount of gas fees in order to carry out the actions mentioned previously.
+
+As a result, this effectively allows malicious aggregators to grief lenders and borrowers.

+_No response_
+
+### Mitigation
+
+Having a maximum number of offers (e.g., 100) within a single Loan is insufficient to guard against this attack because malicious aggregators can simply work around this restriction by creating more loans.
+
+Thus, it is recommended to impose the minimum size for each loan and/or offer, so that malicious aggregators cannot create many small/tiny loans and offers to grief the users.

+
+Assume that the ratio/price is 1e18 (1 XYZ per ABC => Principle per Collateral). XYZ is 18 decimals while ABC is 6 decimals.
+
+Assume that Bob (malicious borrower) calls the permissionless `DebitaV3Aggregator.matchOffersV3` function. The amount of collateral deducted from Bob's borrow offer is calculated via the following:
+
+```solidity
+userUsedCollateral = (lendAmountPerOrder[i] * (10 ** decimalsCollateral)) / ratio;
+userUsedCollateral = (lendAmountPerOrder[i] * 1e6) / 1e18;
+```
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L467
+
+```solidity
+File: DebitaV3Aggregator.sol
+274: function matchOffersV3(
+..SNIP..
+466: // calculate the amount of collateral used by the lender
+467: uint userUsedCollateral = (lendAmountPerOrder[i] *
+468: (10 ** decimalsCollateral)) / ratio;
+```
+
+
+For `lendAmountPerOrder`, he uses a value that is small enough to trigger a rounding to zero error. The range of `lendAmountPerOrder` that will cause `userUsedCollateral` to round down to zero is:
+
+$0≤lendAmountPerOrder<10^{12}$
+
+Thus, for each offer, Bob will specify the `lendAmountPerOrder[i]` to be `1e12 - 1`. Thus, for each offer, he will be able to obtain `1e12 - 1` XYZ tokens without paying a single ABC tokens as collateral.
+
+This attack is profitable because each `matchOffersV3` transaction can execute up to 100 offers, and the protocol is intended to be deployed on L2 chains where gas fees are extremely cheap or even negligible.
+

+
+The `TaxTokensReceipts` NFT receipt exist to allow FOT to be used within the Debita ecosystem. If users have any tokens that charge a tax/fee on transfer, they must deposit them into the `TaxTokensReceipts` NFT receipt and use the NFT within the Debita ecosystem.
+
+The new Debita protocol has a new feature called ["Buy Order" or "Limit Order"](https://debita-finance.gitbook.io/debita-v3/marketplace/limit-order) that allows users to create buy orders, providing a mechanism for injecting liquidity to purchase specific receipts at predetermined ratios. The receipts include the `TaxTokensReceipts` NFT receipt.
+
+Assume that Bob creates a new Buy Order to purchase `TaxTokensReceipts` NFT receipt. Alice, the holder of `TaxTokensReceipts` NFT receipt, decided to sell it to Bob's Buy Order. Thus, she called the `buyOrder.sellNFT()` function, and Line 99 below will attempt to transfer Alice's `TaxTokensReceipts` NFT receipt to the Buy Order contract.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L99
+
+```solidity
+File: buyOrder.sol
+092: function sellNFT(uint receiptID) public {
+093: require(buyInformation.isActive, "Buy order is not active");
+094: require(
+095: buyInformation.availableAmount > 0,
+096: "Buy order is not available"

+099: IERC721(buyInformation.wantedToken).transferFrom(
+100: msg.sender,
+101: address(this),
+102: receiptID
+103: );
+```
+
+However, the transfer will always revert because the transfer function has been overwritten, as shown below. The transfer function has been overwritten to only allow the transfer to proceed if the `to` or `from` involves the following three (3) contracts:
+
+1. Borrow Order Contract
+2. Lend Order Contract
+3. Loan Contract
+
+Since neither the Buy Order contract nor the seller (Alice) is the above three contracts, the transfer will always fail. Thus, there is no way for anyone to sell their `TaxTokensReceipts` NFT receipt to the buy order. Thus, this feature is effectively broken.

+# Malicious users can exploit incentives by lending to themselves
+
+### Summary

+The lack of relationship checks between borrowers and lenders in the incentives system will allow users to game the incentives mechanism by lending to themselves, resulting in unfair rewards distribution as malicious users can artificially inflate their incentive rewards.
+
+### Root Cause

+Assume the following:
+
+- decimalsToken0 (EQUAL) = 6 decimals
+- decimalsToken1 (XYZ) = 18 decimals
+
+The `twapPrice112x112` is computed by taking the reserve/balance of both tokens (EQUAL and XYZ) in the pool, dividing them, and scaling up by Q112 (2* 112), as shown below.
+
+The price/ratio will be token1 per token0, which will be XYZ per EQUAL.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/MixOracle/TarotOracle/TarotPriceOracle.sol#L43
+
+```solidity
+File: TarotPriceOracle.sol
+33: function getPriceCumulativeCurrent(
+34: address uniswapV2Pair
+35: ) internal view returns (uint256 priceCumulative) {
+36: priceCumulative = IUniswapV2Pair(uniswapV2Pair)
+37: .reserve0CumulativeLast();
+38: (
+39: uint112 reserve0, // @audit-info EQUAL
+40: uint112 reserve1, // @audit-info XYZ
+41: uint32 _blockTimestampLast
+42: ) = IUniswapV2Pair(uniswapV2Pair).getReserves();
+43: uint224 priceLatest = UQ112x112.encode(reserve1).uqdiv(reserve0); // @audit-info XYZ divided by EQUAL
+```
+
+Assume that the current market price/ratio is 10 million (10e6) XYZ per EQUAL. In this case, `twapPrice112x112` will be equal to `(10e6/1e18 * (2**112))`, as shown below.
+
+```solidity
+twapPrice112x112 (XYZ per EQUAL) = XYZ/EQUAL (XYZ divided by EQUAL) = 10e6 XYZ per EQUAL = (10e6 * 1e18)/1e6 = (10e24/1e6 * (2**112)) scaled up by 112
+```
+
+Next, the `amountOfAttached` will be computed at Line 61 below via the following formula to obtain the price/ratio for EQUAL per XYZ. This means that 0.1 EQUAL per XYZ, which is correct.
+
+```solidity
+amountOfAttached = ((2**112) * (10**decimalsToken1)) / twapPrice112x112
+amountOfAttached = ((2**112) * (10**18)) / (10e24/1e6 * (2**112))
+amountOfAttached = (1e18) / (10e24/1e6) = 0.1 = 0 (Solidity Round Down)
+```
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/MixOracle/MixOracle.sol#L61
+
+```solidity
+File: MixOracle.sol
+53: // Get the price from the pyth contract, no older than 20 minutes
+54: // get usd price of token0
+55: int attachedTokenPrice = IPyth(debitaPythOracle).getThePrice(attached); // @audit-info attached => XYZ | USD per XYZ | How much in terms of USD each XYZ is worth
+56: uint decimalsToken1 = ERC20(attached).decimals(); // @audit-info From Pyth | XYZ's decimal = 18
+57: uint decimalsToken0 = ERC20(tokenAddress).decimals(); // @audit-info From Tarot | EQUAL's decimal = 18
+58:
+59: // calculate the amount of attached token that is needed to get 1 token1
+60: int amountOfAttached = int(
+61: (((2 ** 112)) * (10 ** decimalsToken1)) / twapPrice112x112 // @audit-info 1 XYZ / (EQUAL per XYZ) => Become XYZ per EQUAL
+62: );
+63:
+64: // calculate the price of 1 token1 in usd based on the attached token
+65: uint price = (uint(amountOfAttached) * uint(attachedTokenPrice)) /
+66: (10 ** decimalsToken1);
+67:
+68: require(price > 0, "Invalid price");
+```
+
+However, the `amountOfAttached` will round down to zero, and cause a revert in Line 68 above.
+
+Thus, in an edge case where a high-value token is paired with a low-value token (e.g., XYZ and EQUAL in the above scenario), the price oracle will always revert.
+
+This can happen in real-life scenarios, and many token pairs exhibit this characteristic. Some examples of such token pairs are:
+
+- WBTC<>SHIBA, where the ratio/price is around 3.7 billion SHIBA per WBTC
+- ETH<>SHIBA, where the ratio/price is around 125 million SHIBA per ETH
+- ETH<>SAFEMOON, where the ratio/price is around 100 million SAFEMOON per ETH
+
+### Impact
+
+High. Loss of assets and breaking core contract functionality
+
+The following are the negative impacts of this issue:
+
+- (Most severe impact) Loss of assets. In the above example, if the price is an initial 9 million (9e6) XYZ per EQUAL, the price will operate normally and issue a Loan. When the price goes beyond 10 million (10e6) XYZ per EQUAL, all auctions will break due to the oracle reverts, leading to defaulted collateral not being able to be auctioned off and lenders not being repaid.
+- Breaking core contract functionality. Price oracle is broken.

+The following is the extract from the [contest's README](https://github.com/sherlock-audit/2024-11-debita-finance-v3-xiaoming9090?tab=readme-ov-file#q-if-you-are-integrating-tokens-are-you-allowing-only-whitelisted-tokens-to-work-with-the-codebase-or-any-complying-with-the-standard-are-they-assumed-to-have-certain-properties-eg-be-non-reentrant-are-there-any-types-of-weird-tokens-you-want-to-integrate):
+
+> Q: If you are integrating tokens, are you allowing only whitelisted tokens to work with the codebase or any complying with the standard? Are they assumed to have certain properties, e.g. be non-reentrant? Are there any types of [weird tokens](https://github.com/d-xo/weird-erc20) you want to integrate?
+>
+> - Fee-on-transfer tokens will be used only in TaxTokensReceipt contract
+
+Thus, Fee-on-Transfer (FOT) tokens are supported within the protocol as long as it is wrapped within the `TaxTokensReceipt contract`.
+
+Assume that Alice has 100 FOT tokens that she wants to lend out. To use FOT within Debita, she calls the `TaxTokensReceipts.execute` function to deposit her 100 FOT, and a `TaxTokensReceipts` receipt NFT with 100 FOT locked amount will be minted to Alice to be used within Debita.
+
+Next, Alice calls the `DLOFactory.createLendOrder` function to create a lend order to lend out her 100 FOT tokens.
+
+However, the issue is that the function does not accept her `TaxTokensReceipts` receipt NFT with 100 FOT locked amount because it only uses `SafeERC20.safeTransferFrom` function. Thus, the `DebitaLendOfferFactory.createLendOrder` function is considered broken as it cannot support FOT while it is supposed to.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L177
+
+```solidity
+File: DebitaLendOfferFactory.sol
+124: function createLendOrder(
+..SNIP..
+177: SafeERC20.safeTransferFrom(
+178: IERC20(_principle),

+183:
+184: uint balance = IERC20(_principle).balanceOf(address(lendOffer));
+185: require(balance >= _startedLendingAmount, "Transfer failed");
+```
+
+### Impact
+
+Medium. Breaks core contract functionality since the protocol is designed to support FOT by wrapping it within the `TaxTokensReceipt`. However, due to this bug, FOT cannot be used within lend order.

+
+The [Debita documentation](https://debita-finance.gitbook.io/debita-v3/lending/incentives) contains a detailed explanation of the Incentive mechanism.
+
+In summary, the amount of incentive each user can receive depends on the total number of tokens that they have borrowed or lent in each epoch (one epoch = 14 days).
+
+Assume that the incentive for borrowing a principle token called $P$ is 10 WETH, 10 WETH, 10 WETH for Epoch 101, Epoch 102, and Epoch 103, respectively. In this case, if Alice borrows 30 USDC and Bob borrows 70 USDC in Epoch 101, Alice will be able to claim 3 WETH, while Bob will be able to claim 7 WETH. The distribution of incentives per epoch is purely based on the proportion.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L200
+
+```solidity
+File: DebitaIncentives.sol
+142: function claimIncentives(
+..SNIP..
+177: for (uint j = 0; j < tokensIncentives[i].length; j++) {
+178: address token = tokensIncentives[i][j];
+179: uint lentIncentive = lentIncentivesPerTokenPerEpoch[principle][
+180: hashVariables(token, epoch)
+181: ];
+182: uint borrowIncentive = borrowedIncentivesPerTokenPerEpoch[
+183: principle
+184: ][hashVariables(token, epoch)];
+..SNIP..
+200: uint amountToClaim = (lentIncentive * porcentageLent) / 10000;
+201: amountToClaim += (borrowIncentive * porcentageBorrow) / 10000;
+```
+
+However, the issue is that malicious users can match their own orders a few seconds before the Epoch ends and withdraw the Loan immediately a few seconds after the new Epoch starts. For instance:
+
+- On `Epoch 101 - 3 seconds` - Bob matches his own lend and borrow orders, and borrows 1000 $P$ token. As a result, `borrowedIncentivesPerTokenPerEpoch[P][hash(WETH, Epoch 101)] = 1000 P`
+- On `Epoch 102 + 3 seconds` - Bob's Loan deadline has been reached, and he can claim back all the collateral.
+- On `Epoch 102 + 3 seconds` - Bob can claim 1000 $P$ worth of incentive from Epoch 101, depending on his proportion against the rest of the users.
+
+Alternatively, if Bob is not well-funded, he can leverage a flash loan to create a borrow-and-loan order with zero duration. The protocol does not prevent zero duration during the creation of a borrow/loan order and also does not impose a minimum duration for the Loan to be created. Thus, this is technically possible. After Bob matches his own orders, `borrowedIncentivesPerTokenPerEpoch[P][hash(WETH, Epoch 101)] = 1000 P` and he can claim the incentive in the next Epoch.
+
+The fee to be paid depends on the following formula below. In the worst-case scenario, the highest possible fee is only 1.0%. If Bob borrows 1000 $P$, he would only need to pay a maximum of 10 $P$ in the worst-case scenario. In reality, he will be paying the minimum fee (e.g., 0.1%) because the duration is so short and `percentage` computed will always be lower than the `minFee`.
+
+Assuming a worst-case scenario. At the last block or last few seconds, Bob can fetch the total borrow amount in the current epoch. From here, he determines, based on the current total borrow amount, whether or not it is profitable to carry out the attack. If the incentive gain is larger than 10 $P$ (1.0%) he paid as a fee, he will proceed with the attack. Obviously, this will be done automatically via bots/scripts.
+
+The rest of the innocent users will be affected by Bob's "just-in-time" attack, as Bob will dilute their proportion in the epoch, leading to the victim claiming a smaller proportion of the incentive and a loss of funds for the victims.
+
+```solidity
+feePerDay = From 1 to 10 (0.01% to 0.1%)
+
+uint percentage = ((borrowInfo.duration * feePerDay) / 86400);
+
+// fix the percentage of the fees
+if (percentage > maxFEE) { // @audit-info maxFEE = 0.5% to 1.0%
+ percentage = maxFEE;
+}
+
+if (percentage < minFEE) { // @audit-info minFEE = 0.1% to 0.5%
+ percentage = minFEE;
+}
+
+uint feeToPay = (amountPerPrinciple[i] * percentage) / 10000;
+```
+
+### Impact
+
+High. Innocent users will be affected by Bob's "just-in-time" attack, as Bob will dilute their proportion in the epoch, leading to the victim claiming a smaller proportion of the incentive and a loss of funds for the victims.

+# Ownership cannot be Changed
+
+### Summary
+
+The ``changeOwner function`` contains a logical flaw that prevents the ``owner`` variable from ever being updated. The assignment ``owner = owner`` effectively reassigns the ``owner`` variable to itself, rendering the function non-functional for its intended purpose of changing ownership.
+
+### Root Cause
+
+The issue lies in the statement:
+```solidity
+owner = owner;
+```
+This assignment does not update the ``owner`` variable to the new owner address provided as the function argument. Instead, it redundantly assigns the current value of ``owner`` back to itself, failing to change ownership.
+
+### Internal pre-conditions
+
+1. The caller must pass the require check for ``msg.sender == owner``.
+2. The function can only be called within 6 hours of the contract’s deployment (``deployedTime + 6 hours > block.timestamp``)
+
+### External pre-conditions
+
+1. A user with the current ``owner`` address must attempt to call the ``changeOwner`` function.
+2. The current block timestamp must be within 6 hours of the contract’s deployment.
+
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+1. Ownership remains locked to the address specified during the contract's deployment.
+2. No flexibility to delegate or transfer contract control to another address.

+# Potential for auctions to execute at bad prices for the seller
+
+### Summary
+
+The issue comes down to the fact that the price in the dutch auction will be continually decreasing even if there is current sequencer downtime. The price will decrease despite there being no chance for the prospective buyers to purchase the nft through the [buyNFT function](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109-L161) So, the seller may not get as high a price as they would have been able to gain otherwise.
+
+### Root Cause
+
+The issue derives from the tendency for l2s like arbitrum (which this protocol will be deployed to), to experience periods of downtime. During this time, no transactions will be able to take place, however, the price of the dutch auction, will still continue to fall (`uint decreasedAmount = m_currentAuction.tickPerBlock * timePassed;`) as time passes, therefore, the prices the seller receives from the auction, have a decent chance of not being the maximum amount they could achieve, so there are losses for the seller.
+
+A similar issue was referenced [here too](https://solodit.cyfrin.io/issues/m-3-no-check-for-sequencer-uptime-can-lead-to-dutch-auctions-executing-at-bad-prices-sherlock-none-index-update-git)

+# If no borrow and lend orders are matched during an epoch, the rewards for that epoch will be locked in the contract forever
+
+### Summary
+
+The ``DebitaIncentives.sol`` contract allows users to incentivize other users to create borrow and lend orders for certain principles. They can do that by calling the [incentivizePair()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L225-L294) function and transfer the incentive token into the ``DebitaIncentives.sol`` contract. However if there are no borrow and lend orders that are matched for a specific principle that has been incentivized for a certain epoch, the incentives tokens transferred into the ``DebitaIncentives.sol`` contract will be locked forever, and they can't be utilized as incentives for an up and coming epoch. This essentially results in the users who are incentivizing for a specific principal token loosing the tokens they deposited as incentives, and not accomplishing their goal of making borrowers and lenders create orders for the specific principal.
+
+### Root Cause
+
+In the ``DebitaIncentives.sol`` contract, there is no functionality that allows users who deposited incentives tokens for a specific principal token and an epoch, to either withdraw or utilize the already deposited(but not utilized) incentive tokens in a future epoch, in a scenario where no borrow and lend orders were matched for the specific principal during the epoch.

+# Chainlink's `latestRoundData` might return stale or incorrect results
+
+### Summary
+
+In the `DebitaChainlink` contract, the protocol uses a ChainLink aggregator to retrieve the `latestRoundData()`, However, there is no verification to determine if the returned data is stale. The only check present is for the `price` to be `> 0`;. This alone is not sufficient.
+
+
+### Root Cause
+
+```solidity
+ function getThePrice(address tokenAddress) public view returns (int) {
+ // falta hacer un chequeo para las l2
+ address _priceFeed = priceFeeds[tokenAddress];
+ require(!isPaused, "Contract is paused");
+ require(_priceFeed != address(0), "Price feed not set");
+ AggregatorV3Interface priceFeed = AggregatorV3Interface(_priceFeed);
+
+ // if sequencer is set, check if it's up
+ // if it's down, revert
+ if (address(sequencerUptimeFeed) != address(0)) {
+ checkSequencer();
+ }
+ @> (, int price, , , ) = priceFeed.latestRoundData();
+
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+ require(price > 0, "Invalid price");
+ return price;
+ }
+```
+In the function above, the part marked `@>` uses a ChainLink aggregator to retrieve the `latestRoundData()`. As you can see the check for price present is ` require(price > 0, "Invalid price");`.
+
+The implementation above could lead to stale prices according to the [Chainlink documentation](https://docs.chain.link/docs/historical-price-data/#historical-rounds).
+
+The functions [createLendOrder](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L124) and [createBorrowOrder](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L75) can utilize the DebitaChainlink oracle when creating offers and may eventually end up returning incorrect data.

+# Missing `endBlock` Enforcement in `Auction.sol`
+
+## Summary
+The Dutch Auction contract does not enforce a check for the auction's endBlock (expiration time). This allows users to interact with the auction, including purchasing the NFT or editing parameters, even after the auction should have ended. This flaw undermines the integrity of the auction system and exposes it to misuse.
+
+## Vulnerability Details
+**Affected Functions:**
+- buyNFT
+
+- editFloorPrice
+
+- cancelAuction
+
+**Issue:** None of these functions validate whether the current block timestamp (block.timestamp) exceeds the endBlock of the auction.
+
+## Code Link
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol
+## Impact
+**Unauthorized Purchases:** Users can buy the NFT at an expired price, often at the floor price, exploiting the lack of a valid auction period.
+**Parameter Manipulation:** Auction owners can edit the floor price or duration of an expired auction to prolong its activity unfairly.
+**Misleading Auction Status:** Participants may believe the auction is still active, leading to confusion and potential financial loss.
+**System Inefficiency:** Expired auctions remain in the system, bloating the auction factory and causing unnecessary operational load.
+## Recommendation
+**Add endBlock Check:**
+Create a modifier, onlyBeforeEnd, to enforce expiration logic:
+```solidity
+modifier onlyBeforeEnd() {
+ require(block.timestamp <= s_CurrentAuction.endBlock, "Auction expired");
+ _;
+}
+```
+Apply this modifier to critical functions (buyNFT, editFloorPrice, and cancelAuction).
+
+**Graceful Expiry Handling:**
+Implement an expireAuction function to deactivate expired auctions and clean up factory records:
+```solidity
+function expireAuction() public {
+ if (block.timestamp > s_CurrentAuction.endBlock && s_CurrentAuction.isActive) {
+ s_CurrentAuction.isActive = false;
+ auctionFactory(factory)._deleteAuctionOrder(address(this));
+ auctionFactory(factory).emitAuctionDeleted(address(this), s_ownerOfAuction);
+ }
+}
+```

+# NFT liquidation design flaw leads to borrower default chain reaction
+
+### Summary
+
+The design choice to liquidate the NFT collateral upon a single loan default may cause a significant loss for borrowers and lenders as borrowers will have no incentive to repay remaining non-defaulted loans after their NFT is sold at a very low price in a Dutch auction.
+
+### Root Cause
+
+function createAuctionForCollateral:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L417

+The design to liquidate the NFT collateral for a single loan default may creates a negative feedback loop where:
+1. One defaulted loan triggers NFT liquidation
+2. NFT likely sells very low value in Dutch auction
+3. Borrower loses incentive to repay remaining healthy loans
+4. More loans default unnecessarily
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Borrower takes multiple loans using a single NFT as collateral
+2. One loan defaults, triggering NFT liquidation
+`DebitaV3Loan.sol`
+```solidity
+require(nextDeadline() < block.timestamp, "Deadline not passed");
+require(m_loan.auctionInitialized == false, "Already initialized");
+```
+3. Entire NFT is auctioned via Dutch auction mechanism:
+`Auction.sol`
+```solidity
+function getCurrentPrice() public view returns (uint) {
+//...
+ uint decreasedAmount = m_currentAuction.tickPerBlock * timePassed;
+ uint currentPrice = (decreasedAmount >
+ (m_currentAuction.initAmount - floorPrice))
+ ? floorPrice
+ : m_currentAuction.initAmount - decreasedAmount;
+//...
+}
+```
+4. NFT likely sells very low value due to Dutch auction price decay
+5. Borrower has no incentive to repay remaining healthy loans since the collateral in very low value
+6. Additional loans default unnecessarily
+
+### Impact
+
+The borrowers may suffer much loss of their NFT collateral value when one loan defaults. The lenders of non-defaulted loans also suffer losses as borrowers abandon repayment after NFT liquidation. This creates a negative spiral of unnecessary defaults.

+# veNFT Becomes Stuck in `buyOrder` Contract Due to Incorrect `ERC721.transferFrom` Address in the `buyOrder::sellNFT` function
+
+### Summary
+
+An incorrect address in the `buyOrder::sellNFT` function causes NFTs to be sent to the `buyOrder` contract instead of the intended buyer(owner). This results in the NFT being permanently stuck in the contract as it lacks a function for buyers to claim them.
+
+### Root Cause
+
+In the [buyOrder::sellNFT](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L99-L103) function:
+
+```solidity
+function sellNFT(uint receiptID) public {
+ // ...
+ IERC721(buyInformation.wantedToken).transferFrom(
+ msg.sender,
+@> address(this),
+ receiptID
+ );
+ // ...
+}
+```
+
+The `IERC721.transferFrom` call incorrectly transfers the NFT to the `buyOrder` contract's `address (address(this))` instead of directly to the buyer (the buyOrder contract's `owner`). This results in the NFT being permanently stuck in the contract since it doesn't have any other mechanism for the buyer to claim it.
+
+### Internal pre-conditions
+
+1. A seller must call `sellNFT()` with a valid receiptID.
+2. buyInformation.isActive must be `true`.
+3. `buyInformation.availableAmount` must be greater than `0`
+
+### External pre-conditions
+
+1. A buyer has placed a buy order with a valid NFT receipt Id and has sufficient funds.
+
+### Attack Path
+
+1. Seller calls `buyerOrder::sellNFT()` with a valid receipt ID.
+2. The contract transfers the NFT to its address `(address(this))` instead of the `buyer(owner)`.
+3. The NFT remains locked in the contract as it lacks a function for the buyer to claim it.
+
+### Impact
+
+The buyer's NFT permanently loses their NFT as it is stuck in the `buyerOrder` contract. Buyers are unable to receive the NFT despite transferring their token causing financial loss to them.
+
+### PoC
+
+1. Deploys a mock veNFT:
+
+```solidity
+contract MockVeNFT is ERC721Enumerable {
+ struct LockedBalance {
+ int128 amount;
+ uint256 end;
+ bool isPermanent;
+ }
+
+ mapping(uint256 => LockedBalance) public lock;
+ address public voter;
+
+ constructor() ERC721("MockVeNFT", "vNFT") {}
+
+ function mint(address to) external returns (uint256) {
+ uint256 tokenId = totalSupply() + 1;
+ _mint(to, tokenId);
+
+ // Mock lock data needed by receipt system
+ lock[tokenId] = LockedBalance({
+ amount: int128(100e18), // 100 token locked
+ end: block.timestamp + 365 days,
+ isPermanent: false
+ });
+
+ return tokenId;
+ }
+
+ // Required by receipt system
+ function locked(
+ uint256 tokenId
+ ) external view returns (LockedBalance memory) {
+ return lock[tokenId];
+ }
+}
+```
+
+2. Deploy all necessary contracts.
+3. Create a `buyOrder` contract and call `sellNFT`
+```solidity
+contract BuyOrderTest is Test {
+ buyOrderFactory factory;
+ BuyOrder buyOrderImplementation;

+

+
+ function setUp() public {

+
+ // deploy buy order factory contract

+
+ // mint buyer some erc20 token
+ underlyingToken.mint(buyer, 1000e18);
+
+ vm.startPrank(nftHolder);
+ // mint veNFT to user
+ uint256 veTokenId = veNFT.mint(nftHolder);
+
+ // approve and deposit into receipt system
+ veNFT.approve(address(receiptContract), veTokenId);
+
+ uint256[] memory nftIds = new uint256[](1);
+ nftIds[0] = veTokenId;
+
+ // deposit into receipt contract
+ receiptContract.deposit(nftIds);
+
+ // verify receipt ownership
+ assertEq(receiptContract.ownerOf(receiptId), nftHolder);
+
+ vm.stopPrank();
+ }
+
+ function test_BuyerDidnotReceiveNFT() public {
+ vm.startPrank(buyer);
+ // buyer approve factory to spend token
+ underlyingToken.approve(address(factory), 1000e18);
+
+ // Create buy order
+ // Parameters: buyToken, wantedToken, amount, ratio
+ address buyOrderAddr = factory.createBuyOrder(
+ address(underlyingToken), // paying with underlying token
+ address(receiptContract), // want to buy receipt NFT
+ 100e18, // willing to spend 100 tokens
+ 1e18 // 1:1 ratio
+ );
+ vm.stopPrank();
+

+ assertEq(receiptContract.ownerOf(receiptId), address(buyOrderAddr));
+ // buyer did not receive his NFT token
+ assertNotEq(receiptContract.ownerOf(receiptId), buyer);
+ }
+}
+```
+
+4. Test log shows the NFT's owner is the `buyOrder` contract instead of the owner(buyer)
+```solidity

+
+### Mitigation
+
+Correct the `to` address in the `buyerOrder::sellNFT` function to transfer the NFT directly to the buyer’s address instead of the contract address.

+# Unauthorized initialization of `DebitaV3Loan` contract
+
+### Summary
+
+The `DebitaV3Loan` contract allows any user to call the `initialize()` function and set themselves as the owner, bypassing the intended initialization process via the `DebitaV3Aggregator`. This vulnerability arises because the implementation contract is deployed without locking the `initialize()` function, leaving it exposed to malicious actors.
+
+### Root Cause
+
+The root cause of this vulnerability is the absence of a mechanism to lock the `initialize()` function in the `DebitaV3Loan` contract. Since `DebitaV3Loan` is deployed before `DebitaV3Aggregator`, the `initialize()` function is callable by any user until a proxy uses it. This allows a malicious actor to:
+
+1. Deploy the `DebitaV3Loan` contract.
+
+2. Call `initialize()` directly, setting themselves as the owner and initializing the contract.
+
+3. Exploit ownership to manipulate the contract's state or assets.
+
+The lack of protection in the constructor to prevent direct initialization is the fundamental flaw.
+
+### Attack Path
+
+1. Deploy the `DebitaV3Loan` contract.
+
+2. Call the `initialize()` function directly with arbitrary parameters.
+
+3. Become the contract owner and gain full control over the contract.
+
+4. Exploit the contract by misusing its functionality or causing it to behave unpredictably.
+
+### Impact
+
+The impact of this vulnerability is severe:
+
+1. **Unauthorized Ownership**: Malicious actors can gain control of the `DebitaV3Loan` contract.
+
+2. **Asset Theft**: If assets are transferred to this contract before proper initialization, the attacker can steal them.
+
+3. **System Integrity**: The integrity of the `DebitaV3Aggregator` and the entire borrowing/lending process is compromised as unauthorized contracts can be treated as legitimate.
+
+### Code Snippet
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L138
+
+### Mitigation
+
+To prevent this vulnerability, use the OpenZeppelin-provided `_disableInitializers()` function to lock the `DebitaV3Loan` contract upon deployment. This ensures the `initialize()` function cannot be called on the `DebitaV3Loan` contract itself.
+
+**Recommended Fix**
+
+Modify by adding constructor in `DebitaV3Loan` as follows:
+
+```solidity
+constructor() {
+ _disableInitializers();
+}
+```
+
+This guarantees the `initialize()` function is only callable on proxies and not on the `DebitaV3Loan` contract directly.

+# [M-2]: `getHistoricalBuyOrders` will revert transaction with 'array out-of-bounds access' when `offset + limit` is bigger than `historicalBuyOrders.length`
+
+### Summary
+
+`getHistoricalBuyOrders` in buyOrderFactory.sol:159 defines a variable `length ` which is not used afterwards in the function.
+The actual bound of the for loop in the `getHistoricalBuyOrders` is `offset + limit` which can be bigger than `historicalBuyOrders.length` potentially causing 'array out-of-bounds access' exception.
+
+### Root Cause
+
+`getHistoricalBuyOrders` in buyOrderFactory.sol:159 defines a variable:
+
+```solidity
+ uint length = limit;
+
+ if (limit > historicalBuyOrders.length) {
+ length = historicalBuyOrders.length;
+ }
+```
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol?plain=1#L163
+
+In the same function, this variable is not used and the loop will iterate over until `offset + limit` which can be bigger than `historicalBuyOrders.length` potentially causing 'array out-of-bounds access' exception.
+
+```solidity
+@> for (uint i = offset; i < offset + limit; i++) {
+ address order = historicalBuyOrders[i];
+ _historicalBuyOrders[i] = BuyOrder(order).getBuyInfo();
+ }
+```
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol?plain=1#L172
+
+
+### Internal pre-conditions
+

+```
+
+### Mitigation
+
+**Use the `length` variable with some contraints:** The variable `length` could be used below in the `for` loop with mindfulness that the length of `historicalBuyOrders` could become quite big. So additional cap can be introduced as well to prevent the potential transaction failing due to a high gas usage (such as in the case of `getHistoricalAuctions()` in `ActionFactory.sol:104`, reported [here](https://github.com/sherlock-audit/2024-11-debita-finance-v3-SophiaKiryakova/issues/1)).

+# `TaxTokensReceipt` lacks support for all FoT tokens
+
+### Summary
+
+According to the README, three are no restrictions to what fee-on-transfer token is used to deploy `TaxTokensReceipt` contract. The code assumes that the FoT token for which `deposit()` is called set corresponding `TaxTokensReceipt` contract as exempt from tax. Unfortunately, this constraint is not possible for all FoT tokens and for them `deposit()` will always revert:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L68-L69
+
+
+### Root Cause
+
+As outlined in the README, the `TaxTokensReceipt` contract may be deployed for FoT tokens for which tax exemption will be impossible.
+
+
+### Internal pre-conditions
+
+FoT token for which the `TaxTokensReceipt` contract was deployed does not have the functionality of freeing certain addresses from the transfer fee.
+
+
+### External pre-conditions
+
+--
+
+### Attack Path
+
+--
+
+### Impact
+
+Creating receipt does not work for **all** FoT tokens, which should be true according to the README.
+
+### PoC
+
+When transfer is made with FoT token, `balanceAfter - balanceBefore` will be less than the value of the transfer. Therefore this will revert:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L69
+
+
+### Mitigation
+
+Verify that the tax exemption is activated in the constructor or ensure `TaxTokensReceipt` is deployed only for FoT tokens with this functionality accessible for that contract.

+
+### Summary
+
+Any user can create lend orders by using [`DebitaLendOfferFactory::createLendOrder`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L124) function and similarly cancel their offers by using the [`DebitaLendOffer-Implementation::cancelOffer`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L144) function.

+ isActive = false; <@ - // Missing check `require(isActive == true, "Order inactive");`
+ // Rest of the code . . . . .
+ }
+```
+This can be repeated several times to manipulate the `activeOrdersCount`, `allActiveLendOrders` and `LendOrderIndex` leading to loss of orders from the `DebitaLendOfferFactory` contract and the attacker can potentially do this to make sure the `activeOrdersCount` goes to 0, which will deny any legitimate user from cancelling their offer as `deleteOrder` will underflow.
+```solidity
+ function deleteOrder(address _lendOrder) external onlyLendOrder {
+ uint index = LendOrderIndex[_lendOrder];
+ LendOrderIndex[_lendOrder] = 0; <@ - // Loss of orders from mapping
+
+ // switch index of the last borrow order to the deleted borrow order
+ allActiveLendOrders[index] = allActiveLendOrders[activeOrdersCount - 1]; <@ - // Loss of orders from mapping
+ LendOrderIndex[allActiveLendOrders[activeOrdersCount - 1]] = index;
+
+ // take out last borrow order
+
+ allActiveLendOrders[activeOrdersCount - 1] = address(0);
+
+ activeOrdersCount--; // <@ // This will underflow when activeOrdersCount is 0
+ }
+```
+Addition to this, the [`DebitaLendOfferFactory::getActiveOrders`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L222) will not return correct values, as the orders would have been overwritten.
+
+### Root Cause
+
+In [`DebitaLendOffer-Implementation::cancelOffer`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L144), there's a missing `isActive` check that ensures that we cancel only active orders.
+```solidity
+ function cancelOffer() public onlyOwner nonReentrant {
+ uint availableAmount = lendInformation.availableAmount;
+ lendInformation.perpetual = false;
+ lendInformation.availableAmount = 0;
+ require(availableAmount > 0, "No funds to cancel");
+ isActive = false; <@ - // Missing check `require(isActive == true, "Order inactive");`
+ // Rest of the code . . . . .
+ }
+```
+
+In [`DebitaLendOffer-Implementation::addFunds`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L162), we allow addition of funds to an order which is inactive.
+```solidity
+ function addFunds(uint amount) public nonReentrant {
+ require(

+### Internal pre-conditions

+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. User A creates a lend order using `DebitaLendOfferFactory::createLendOrder` function legitimately. Which will make the `activeOrdersCount == 1`.
+2. Malicious User B creates a lend order as well which will make `activeOrdersCount == 2`.
+3. User B cancels the order using `DebitaLendOffer-Implementation::cancelOffer` function which will make `activeOrdersCount == 1`.
+4. User B adds dust value of funds using the `DebitaLendOffer-Implementation::addFunds` function.
+5. User B again cancels the order using `DebitaLendOffer-Implementation::cancelOffer` which will make `activeOrdersCount == 0`.
+6. If user A tries to cancel his order, this will deny him from doing so as subtraction of `activeOrdersCount` will underflow, also, searching his order using `getActiveOrders` will not return him anything.
+
+### Impact
+
+1. Legitimate users will be denied cancellation of offers which will deny them their funds back.
+2. There will be a improper storage in `activeOrdersCount`, `allActiveLendOrders` and `LendOrderIndex` which will disrupt the working of `getActiveOrders` function in `DebitaLendOfferFactory` contract.
+
+### PoC
+
+The below test was added in `BasicDebitaAggregator.t.sol`:

+ // Now cancel the lend order
+ DLOImplementation lendOrder = DLOImplementation(secondLendOrderAddress);
+ IERC20(AERO).approve(address(lendOrder), 1000e18);
+ lendOrder.cancelOffer();
+
+ assertEq(DLOFactoryContract.activeOrdersCount(), 3);
+ // Attacker adds dust funds and cancels the lend order
+ lendOrder.addFunds(1);
+ lendOrder.cancelOffer();
+
+ assertEq(DLOFactoryContract.activeOrdersCount(), 2);
+ lendOrder.addFunds(1);
+ lendOrder.cancelOffer();
+
+ assertEq(DLOFactoryContract.activeOrdersCount(), 1);
+ lendOrder.addFunds(1);
+ lendOrder.cancelOffer();
+
+ assertEq(DLOFactoryContract.activeOrdersCount(), 0); // Literally Draining the Lend Orders of first 2, new orders will overwrite the old ones, the contract loses track of the old orders
+ // Dis-allows legit users from cancelling orders as well
+ vm.stopPrank();
+
+ vm.startPrank(firstLender);
+ // Try to cancel the lend order
+ vm.expectRevert();
+ DLOImplementation(firstLendOrderAddress).cancelOffer(); // [FAIL: panic: arithmetic underflow or overflow (0x11)]
+ vm.stopPrank();
+
+ }
+```
+It showcases the entire attack path mentioned.
+
+### Mitigation
+
+It is recommended to add `isActive` checks in both `addFunds` and `cancelOffer`
+```diff

+# Ownerships token transferees cannot claim incentives
+
+### Summary
+
+The design choice to bind incentives to original borrower/lender addresses rather than token ownership will cause a loss of incentive rewards for token transferees as new token holders cannot claim incentives associated with their acquired ownership.
+
+### Root Cause
+
+It lacks the transferability of incentive rights when lending/borrowing positions change hands.
+In DebitaIncentives.sol, incentives are tracked using address-based mappings:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L69C1-L75C42

+# An attacker could block the full utilization of a user's lending offer, leading to funds being permanently locked in the contract.
+
+### Summary
+
+There is a critical vulnerability in the ``deleteOrder`` function, exacerbated by its integration with the ``changePerp`` function. This flaw allows a malicious user to manipulate the lifecycle of lending offers, rendering the protocol unreliable and potentially disrupting the functionality of legitimate users.
+
+The root cause of the issue lies in the improper state management of lending offers, where an active lending offer can be repeatedly deleted through the misuse of the ``changePerp`` function. This exploit not only causes underflows in the ``activeOrdersCount`` variable but also compromises the integrity of the protocol's data structures.
+
+### Root Cause
+
+The core vulnerability lies in the absence of validation within the ``deleteOrder`` function to ensure that the target order is still active. This flaw allows the same order to be deleted multiple times, leading to the following consequences:
+
+1. **Repeated Deletion Corrupts Data Structures**: Each deletion operation replaces the order at the given index with the last active order and decrements the ``activeOrdersCount``. Repeated deletions, however, reduce ``activeOrdersCount`` below its intended value, resulting in corrupted ``allActiveLendOrders`` and ``LendOrderIndex`` mappings.
+
+2. **Underflow in activeOrdersCount**: When legitimate users or automated processes attempt to delete or cancel offers after the malicious reduction of ``activeOrdersCount`` to 0, the line:
+
+``allActiveLendOrders[index] = allActiveLendOrders[activeOrdersCount - 1]``;
+triggers an underflow, as subtracting 1 from 0 results in an invalid array index.
+
+3. **Reversion of Contract Functions**: Both the cancel offer and accept offer processes depend on the integrity of ``activeOrdersCount``. When this value becomes inconsistent, these functions revert unexpectedly, disrupting the normal lifecycle of lending offers.
+
+
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+The exploit hinges on a malicious user creating a lending offer and leveraging the ``changePerp`` function to repeatedly delete active orders. The key steps in the attack are as follows:
+
+1. **Setup the Lending Offer**:
+
+The attacker creates a lending offer and sets ``lendInformation.perpetual`` to ``true``, ensuring the offer remains active indefinitely.
+```solidity
+function initialize(
+ address _aggregatorContract,
+ bool _perpetual,
+ bool[] memory _oraclesActivated,
+ bool _lonelyLender,
+ uint[] memory _maxLTVs,
+ uint _apr,
+ uint _maxDuration,
+ uint _minDuration,
+ address _owner,
+ address _principle,
+ address[] memory _acceptedCollaterals,
+ address[] memory _oracleIDS_Collateral,
+ uint[] memory _ratio,
+ address _oracleID_Principle,
+ uint _startedLendingAmount
+ ) public initializer {
+ aggregatorContract = _aggregatorContract;
+ isActive = true;
+ // update lendInformation
+ lendInformation = LendInfo({
+ lendOrderAddress: address(this),
+ perpetual: _perpetual, <<@Audit set to true
+ oraclesPerPairActivated: _oraclesActivated,
+ lonelyLender: _lonelyLender,
+ maxLTVs: _maxLTVs,
+ apr: _apr,
+ maxDuration: _maxDuration,
+ minDuration: _minDuration,
+ owner: _owner,
+ principle: _principle,
+ acceptedCollaterals: _acceptedCollaterals,
+ oracle_Collaterals: _oracleIDS_Collateral,
+ maxRatio: _ratio,
+ oracle_Principle: _oracleID_Principle,
+ startedLendingAmount: _startedLendingAmount,
+ availableAmount: _startedLendingAmount
+ });
+
+ factoryContract = msg.sender;
+ }
+```
+
+2. **Utilize the Lending Offer Fully**:
+
+The attacker ensures the lending offer is fully utilized, such that:
+```solidity
+lendInformation.availableAmount == 0
+```
+3. **Invoke the changePerp Function**:
+
+With the lending offer fully utilized, the attacker calls the ``changePerp`` function and sets ``_perpetual`` to ``false``.
+The ``changePerp`` function then triggers:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L178
+```solidity
+function changePerpetual(bool _perpetual) public onlyOwner nonReentrant {
+ require(isActive, "Offer is not active");
+
+ lendInformation.perpetual = _perpetual;
+ if (_perpetual == false && lendInformation.availableAmount == 0) {
+ IDLOFactory(factoryContract).emitDelete(address(this));
+ @> IDLOFactory(factoryContract).deleteOrder(address(this));
+ } else {
+ IDLOFactory(factoryContract).emitUpdate(address(this));
+ }
+ }
+```
+This deletes the active lending order and decrements activeOrdersCount.
+4. **Repeat the Deletion**:
+
+The attacker can repeatedly toggle ``lendInformation.perpetual`` between ``true`` and ``false``, triggering successive calls to ``deleteOrder`` until ``activeOrdersCount`` is reduced to ``0``.
+
+
+### Impact
+
+The exploit has far-reaching consequences for the protocol and its users:
+
+1. **Corruption of Active Orders Data**:
+Repeated calls to ``deleteOrder`` corrupt the ``allActiveLendOrders`` and the ``LendOrderIndex`` mapping, resulting in inconsistencies.
+2. **Underflow in activeOrdersCount**:
+The repeated decrements in ``activeOrdersCount`` eventually lead to an underflow. When users or the protocol attempt to access an index using:
+``allActiveLendOrders[activeOrdersCount - 1]``;
+it results in an invalid memory access and a revert.
+3. **Legitimate Users Unable to Cancel Offers**:
+Legitimate users attempting to cancel their lending offers face reverts due to the corrupted ``activeOrdersCount``.
+4. **Disruption of Offer Lifecycle lead to funds been stucked in the Contract**:
+When a fully utilized offer is marked for deletion via:
+```solidity
+if (lendInformation.availableAmount == 0 && !lendInformation.perpetual) {
+ IDLOFactory(factoryContract).deleteOrder(address(this));
+}
+```
+the underflow in activeOrdersCount causes the protocol to revert, preventing the offer from being properly closed.
+
+
+### PoC
+
+Consider a scenario where there are five active lending offers:
+```solidity
+allActiveLendOrders = [A, B, C, D, E]
+LendOrderIndex = {A: 0, B: 1, C: 2, D: 3, E: 4}
+activeOrdersCount = 5
+```
+
+1. **Initial State**:
+- A malicious user creates a perpetual lending offer A and fully utilizes it (``lendInformation.availableAmount == 0``).
+- The user calls changePerp(false):
+``deleteOrder(A)`` is invoked, deleting A from ``allActiveLendOrders``.
+The order at index 0 is replaced with the last active order (E), and ``activeOrdersCount`` is decremented to 4.
+2. **Repeated Calls**:
+- The attacker toggles perpetual back to true and repeats the process:
+- **Second Call**: allActiveLendOrders[0] (now E) is replaced with D.
+- allActiveLendOrders = [D, B, C, 0, 0]
+activeOrdersCount = 3
+- **Third Call**: allActiveLendOrders[0] (now D) is replaced with C.
+allActiveLendOrders = [C, B, 0, 0, 0]
+activeOrdersCount = 2
+3. **Final State**:
+After successive deletions, ``activeOrdersCount`` is reduced to 0, corrupting the state of the system.
+
+I have also prepared a test suite that can be run on remix IDE to illustrate the issue more carefully
+```solidity
+// SPDX-License-Identifier: MIT
+pragma solidity ^0.8.0;
+
+contract LendOrderManager {

+ require(msg.sender != address(0), "Caller must be a valid address");
+ _;
+ }
+
+ // Function to add a new lend order (for testing purposes)

+ allActiveLendOrders[activeOrdersCount] = _lendOrder;

+ }
+
+ // The deleteOrder function you want to test
+ function deleteOrder(address _lendOrder) external onlyLendOrder {
+ uint index = LendOrderIndex[_lendOrder];
+
+ // Reset the index of the lend order being deleted
+ LendOrderIndex[_lendOrder] = 0;
+
+ // Move the last lend order to the index of the deleted lend order
+ allActiveLendOrders[index] = allActiveLendOrders[activeOrdersCount - 1];
+ LendOrderIndex[allActiveLendOrders[activeOrdersCount - 1]] = index;
+
+ // Remove the last lend order from the list
+ allActiveLendOrders[activeOrdersCount - 1] = address(0);
+
+ // Decrease the active orders count
+ activeOrdersCount--;
+ }
+
+
+ // Helper function to get the active lend order at a specific index (for testing purposes)
+ function getLendOrder(uint index) external view returns (address) {

+ }
+
+ // Helper function to get the index of a specific lend order (for testing purposes)
+ function getLendOrderIndex(address _lendOrder) external view returns (uint) {
+ return LendOrderIndex[_lendOrder];
+ }
+}
+```
+
+
+### Mitigation
+
+Set ``isActive`` to ``false`` After Deletion:
+
+Modify the ``changePerp`` function to deactivate the lending offer after calling ``deleteOrder``:
+```solidity
+if (_perpetual == false && lendInformation.availableAmount == 0) {
+ IDLOFactory(factoryContract).emitDelete(address(this));
+ IDLOFactory(factoryContract).deleteOrder(address(this));
+ isActive = false; // Deactivate the lending offer
+}
+```

+# DebitaIncentives.updateFunds(..) does not update funds correctly
+
+### Summary
+
+`DebitaIncentives.updateFunds(infoOfOffers[] memory informationOffers, address collateral, address[] memory lenders, address borrower)` is called by the aggregator whenever orders are matched to update funds for incentivized pairs. However, the `updateFunds()` function will return prematurely when a non-whitelisted pair is encountered and any subsequent whitelisted pairs will not be accounted for, leading to funds loss for the users involved.
+
+### Root Cause
+
+In `DebitaIncentives.updateFunds(..)`, incentivized pairs are checked:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L316
+However, when a non-whitelisted pair is encountered, the function is exited prematurely, as subsequent pairs are skipped completely.
+
+### Internal pre-conditions
+
+N/A
+
+### External pre-conditions
+
+- User incentivizes token pair A/B
+- Aggregator matches order where non-incentivized pair is ordered before the incentivized pair, e.g. pair[0] = A/C, pair[1] = A/B
+
+### Attack Path
+
+1. User incentivizes token pair
+2. Borrowers and lenders create multiple orders respectively, aggregator matches orders where an incentivized pair comes after a non-incentivized pair (note: a malicious aggregator can reorder orders to intentionally block users from acquiring funds, if the malicious aggregator has incentives assigned he'll receive more rewards as other users are left out)
+3. Incentives are not assigned correctly, leading to loss of funds
+
+### Impact
+
+- Users lose rewards permanently
+- Malicious aggregator receives more rewards
+
+### PoC
+
+Note: to see why the PoC works, execute it with the verbose flag (-vvvv) and notice that no `UpdatedFunds(lenders[i], principle, collateral, borrower, _currentEpoch)` event is emitted. Inverting the pair orders will cause the event to be emitted correctly.

+# Borrower loses ability to repay loan due to zero-duration loan exploit
+
+### Summary
+
+A missing duration validation check will cause borrowers to lose their repayment ability as the loan immediately expires, forcing them to forfeit their collateral to lenders through the zero-duration loan mechanism.
+
+### Root Cause
+
+In [DebitaLendOfferFactory.sol:124](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L124) and [DebitaBorrowOffer-Factory.sol:75](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L75) the validation for loan duration allows zero-duration loans to be created when both borrower's and lender's min/max durations are set to 0.
+
+### Internal pre-conditions
+
+1. Borrower needs to create a borrow offer with `duration = 0`
+2. Lender needs to create a lending offer with `minDuration = 0` and `maxDuration = 0`
+3. The loan contract needs to allow matching of these offers
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Attacker identifies a borrow offer with `duration = 0`
+2. Attacker creates a lending offer with: `minDuration = 0` and `maxDuration`= 0
+3. The offers match and create a loan with zero duration
+4. The loan immediately becomes "expired" due to zero duration
+5. Borrower cannot repay the loan as it's already expired
+6. Lender can claim the collateral through `claimCollateralAsLender()`
+
+### Impact
+
+The borrower suffers a complete loss of their collateral. The attacker gains the collateral while only providing the principle amount.
+
+### PoC
+
+```solidity
+// Modify `test/local/Loan/TwoLendersERC20Loan.t.sol`
+// Replace duration arguments with `0` in the setUp() function
+// Add this test to run the PoC
+ function testPoC() public {
+ matchOffers();
+ DebitaV3Loan.LoanData memory loanData = DebitaV3LoanContract
+ .getLoanData();
+ uint[] memory indexes = allDynamicData.getDynamicUintArray(2);
+ indexes[0] = 0;
+ indexes[1] = 1;
+
+ vm.warp(block.timestamp + 1);
+
+ vm.startPrank(borrower);
+ AEROContract.approve(address(DebitaV3LoanContract), 6e18);

+
+ uint balanceAfterFirstLender = USDCContract.balanceOf(firstLender);
+
+ assertGt(
+ balanceAfterFirstLender,
+ balanceBeforeFirstLender
+ );
+ }
+```
+### Mitigation
+
+1. Add duration validation in both borrow and lend offer creation:
+```solidity
+require(
+ duration > 0,
+ "Duration must be greater than zero"
+ );
+ ```
+2. Also add similar checks in the lending offer contract to prevent zero-duration loans.

+# repay wont work
+
+### Summary
+
+when borrowers call repay to repay their loan back the function first sets the loan status to paid =true then it checks if the loan is already paid and if so the function reverts however due how the function is designed the check will always revert
+
+ // change the offer to paid on storage
+ loanData._acceptedOffers[index].paid = true;
+
+
+ // check if it has been already paid
+ require(offer.paid == false, "Already paid");
+
+here we can see it sets the loan status paid= true then the require checks
+offer.paid == false
+
+
+
+### Root Cause
+
+the function changes the status of the loan to paid and then checks if the loan is not already paid which will be true because of this line of code loanData._acceptedOffers[index].paid = true;

+# Incentives Locked Due to Inactivity
+
+### Summary
+
+In [`DebitaIncentives::incentivizePair`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L225-L231), anyone can incentivize any amount of incentive for a specific principle when it is borrowed or lent during a specific epoch.
+
+The problem arises when no activity occurs for that principle within an epoch (a 14-day period) that has been incentivized. In such a case, the [`updateFunds()`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L306-L311) function will not be called, and the [mappings used to split the incentives](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L323-L331) will not be updated. Consequently, the incentives will be permanently locked in the `DebitaIncentives` contract, as there is no way to recover the incentives through `claimIncentives()` or any other function.
+
+### Root Cause
+
+- The decision not to integrate a recovery function for the owner of the incentives, in cases where no activity occurs with an incentivized principle during a specific epoch.
+
+### Internal pre-conditions
+
+No lending activity with any incentivized token occurs during a 14-day period.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+#### Bob incentivizes:
+- **Principle**: LINK
+- **Mode**: Lend
+- **Epoch**: 18
+- **Incentive amount**: 1,000 DAI
+
+During the entire epoch 18, no one lends LINK. As a result, the following mappings are not updated:
+- `lentAmountPerUserPerEpoch`
+- `totalUsedTokenPerEpoch`
+- `borrowAmountPerEpoch`
+
+These mappings are essential in the `claimIncentives()` function to calculate the percentage of incentives ([`percentageLent`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L161) and [`percentageBorrow`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L175)) allocated to corresponding users.
+
+However, as there was no activity, even the owner cannot retrieve the incentives through `claimIncentives()` because all resulting percentages will be zero.
+
+### Impact
+
+Incentives locked forever into the incentives contract.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+#### Add a Function for Recovery of Incentives if No Activity Was Done
+
+- When a user incentivizes a pair, save that user as the owner of the incentives just transferred.
+- Add a function to recover the incentives using the saved owner. Requirements:
+ - The epoch must be finished.
+ - No activity should have occurred during the epoch. Use the `totalUsedTokenPerEpoch` mapping to verify if any activity took place.

+# Everyone can set themselves as an `owner`
+
+### Summary
+
+The function that sets the owner uses the same name for the function parameter, as well as the storage variable.
+
+It checks the `msg.senger` against the `owner`, but the `owner` is not the storage variable (the current owner actually),
+ but the function parameter being passed.
+
+This means that **anyone** can set themselves as an `owner` due to the function parameter being closed to scope than the storage variable.
+
+### Root Cause
+
+The root cause is plain and simple - we should NOT have the same names for the param in `AuctionFactory::changeOwner()` as well as in `DebitaV3Aggregator::changeOwner()`, because the variable that is closer in scope is going to take precedence - in this case: the function param that is an user input and NOT the storage variable, thus bypassing the require statement that checks the `msg.sender` against the `owner`.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. User calls `changeOwner()` passing the same address of his account and gains access to the functions that are reserved for owner only
+
+### Impact
+
+In `DebitaV3Aggregator.sol`, user can set the max & min fee, can set a new fee, can enable or disable oracles as he wishes.
+
+In `AuctionFactory.sol`, user can set the floor price for liquidations, lower or higher depending on what he wants,
+ he can change the auction fee, the public auction fee, change the address from the aggregator contract to another address via `setAggregator()` which is used for checking if the sender is a loan in ` IAggregator(aggregator).isSenderALoan(msg.sender)`.
+
+Basically compromising the integrity of the application and ruining users' trust in it.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Differentiate the function param name with the storage variable name, because if they are the same, the function will take the one that is closer in scope - the function param.

+# No restrictions in DebitaIncentives.sol allows malicious users to farm rewards by creating and matching lend and borrow orders with 0 APR
+
+### Summary
+
+The ``DebitaIncentives.sol`` contract is used by users who wants to incentivize other users to create lend and borrow orders that utilize a certain principal token. Incentives are deposited for each principal for each epoch, which is 14 days. However when lenders and borrowers create orders via the [DebitaLendOfferFactory::createLendOrder()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L124-L203) and the[DebitaBorrowOffer-Factory::createBorrowOrder()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L75-L157) functions respectively, there are no restrictions on the duration and the APR, thus borrow and lend orders with duration of 0 seconds and 0 APR can be created. A couple of minutes before the epoch ends, a malicious user can check what is the amount for the ``totalUsedTokenPerEpoch`` parameter for certain token for the current epoch. If the amount is not that big, the malicious user can execute the below described attack. The [DebitaV3Aggregator::matchOffersV3()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274-L647) function can be called by anyone, thus a malicious user can create a lend and borrow order with 0 APR and 0 seconds duration for an astronomical amount(flash loans can be utilized, as everything happens within the same transaction), and then match them, immediately repaying the loans, creating new orders and matching them again. The malicious actor would only have to a pay a minimum 0.2% fee to the protocol for creating a loan with a minimal duration. If a flash loan is utilized those fees would have to be paid as well. This results in a malicious actor tremendously diluting the incentives for honest users of the Debita protocol, and depending on the dollar amount of the incentives, and the tracked amount of the the ``totalUsedTokenPerEpoch`` provided by honest users, the attacker may be profitable, without risking any of his funds.
+
+### Root Cause
+
+There are no restrictions when borrow and lend orders are created, borrow and lend orders with 0 APR and a duration of 0 seconds can exist. In the ``DebitaIncentives.sol`` contract, there are no restrictions on how long a loan should be, or a minimum APR. There is no locking mechanism of any kind. Also it doesn't matter when in the epoch orders were matched, incentives are distributed purely on the principal amounts used when matching the orders.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+Lets consider an example where someone has provided 5 WETH as incentives for the second epoch and for the USDC principal. The incentive is only for the lenders. Consider the price of WETH is 3000$
+ - Honest users have created borrow and lend orders, and a total of 100_000e6 USDC has been borrowed/lend. The ``totalUsedTokenPerEpoch`` parameter will be equal to 100_000e6, and lenders will split the 5 WETH rewards based on their provided value.
+ - In the last block before the epoch ends(or several blocks beforehand, in order for the malicious user to guarantee his transaction will be executed on time), a malicious user sees that there are only 100_000e6 ``totalUsedTokenPerEpoch``.
+ - The malicious actor decides to create a borrow order with 0 APR, and 0 seconds duration, as well as a lender order with 0 APR and 0 seconds min duration and use USDC as a principal token. The collateral doesn't matter much (it only has to be whitelisted by the ``DebitaIncentives.sol`` contract), lets consider that the collateral is WETH. For easier calculations consider that the borrower put 200 WETH as collateral which is worth 600_000$, at a 100% ratio, the lender order provides 600_000e6 as a principal on 100% ratio as well, meaning that the borrow will receive 3_000e6 USDC for 1e18 WETH.
+ - The malicious actor calls the [DebitaV3Aggregator::matchOffersV3()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274-L647) function, and only pays the minimum 0.2% fee for creating a loan. This is equal to 1200e6 USDC.
+ - If the above step is performed only once when the ``porcentageLent`` is calculated:
+ ```solidity
+ porcentageLent = (lentAmount * 10000) / totalLentAmount;
+```
+ - We get (600_000e6 * 10_000) / 700_000e6 ~ 8_571 which is ~85%. 85% from 5 WETH tokens is 4.25e18 tokens which is 12_750$. The attacker profited ~11_550$, and the non malicious lenders will split 2_250$ between them.
+
+### Impact
+A malicious user can tremendously dilute the incentive rewards that borrowers should receive, and collect a percentage of those rewards. This is a direct theft of funds.

+# Borrower will pay double fee to the lenders
+
+### Summary
+
+Borrower is intended to pay the interest from the start till the time we repay the loan via `payDebt()`.
+
+But before calling `payDebt()`, he may want to extend the loan via `extendLoan()` a little before the end of the initial duration of the loan.
+
+The issue stems from that the user will pay interest to the lender from the start of the loan till the time he invokes `extendLoan()` and when we finally decides to repay the loan via `payDebt()`, he will again pay from the start till the end of the loan - basically we do not account for the difference that was already paid in `extendLoan()`
+
+[Here is the payment from the borrower to the DebitaV3Loan.sol](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L615-L620)

+ from the 1st of November till the 30th and the function is internally used in `extendLoan()` as it is in the code at 28th of November
+ - it will calculate the interest from the 1st to the 28th.
+
+### Root Cause
+
+The root cause is that the borrower will double pay the lenders if he decides to extend the loan via `extendLoan()`, because he will pay interest again from the start of the loan till the repayment happens in `payDebt()`.
+
+The interest payment in `extendLoan()` should not have happened in the first place or it should have been somehow accounted for so that in `payDebt()` we do not pay interest a second time for a period that we've already paid
+.
+The interest payment should be reserved in the `payDebt()` specifically or should have been accounted for in `extendLoan()`.
+
+### Internal pre-conditions
+
+The user invokes `extendLoan()` in the period of the initial duration
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. `Alice` is a borrower and has her borrowing offer matched against one or more lenders - the initial duration is 1th of November till the 30th of November
+2. `Alice` decides to extend the loan at the 28th of November (a little before the end of the initial duration) to its max duration via `extendLoan()` which will be the 25th of December
+3. `Alice` will have to pay the interest to the lender/lenders from the 1st of November till the 28th of November
+4. `Alice` then decides to invoke `payDebt()` at 23th of December to cover the entire debt (principal + interest), but she will have to pay interest to the lenders from the 1st of November till 23th of December which should not been done, because she had already paid from the 1st of November till the 28th of November - this will lead to her paying more than she should have paid, resulting in loss of funds.
+

+# Calculation of the percentage that the borrower will pay to Debita & Connector will be subject to significant rounding down
+
+### Summary
+
+When a borrowing offer is matched against one or more lending offers, the borrower will pay a percentage fee from the principal he'll receive to Debita and the Connector that's calculated [here](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L391).
+
+The issue happens that in certain durations (which will be more common than not) rounding down will be bound to happen and the protocol (Debita) as well as the Connector will receive less fees than expected
+
+### Root Cause
+
+The root cause is not accounting the rounding down in certain durations - which will be significant in some durations such as - 7 days and 8 hours.
+
+In 7 days and 8 hours, the seconds will be `633_600`, the fee per day is a constant of `4` representing 0.04% and the dividor is `86_400`, representing the seconds per day.
+
+This will result in `633_600` * `4` -> `2_534_400` / `86_400` = `29.33`, thus rounding down to `29.33` and losing more than 1% of the fee that should have been paid.
+
+Remember, this will happen on each principal that is on each borrowing offer - basically every single time a lending and a borrowing offers are being matched - this will result in the protocol **receives less fees than expected**,
+ as well as the Connector **getting a smaller share of the fee** he should've gotten.
+
+This will accumulate very fast and result in significantly less fees to the protocol due to the rounding down in certain scenarios.
+
+### Internal pre-conditions

+# Borrower will Pay Higher Fee When Extend The Loan
+
+### Summary
+
+`missingBorrowFee` in `DebitaV3Loan.sol::extendLoan` is miscalculated and will always return highest fee than it should be.
+
+
+### Root Cause
+
+In `DebitaV3Loan::extendLoan`, additional fee must be paid first for loan to be extended. The additional fee is being calculated with `feeOfMaxDeadline - PorcentageOfFeePaid`. This calculation will return a very big value because `feeOfMaxDeadline` is `block.timestamp + maxDuration` or the total timestamp from January 1, 1970 until the maxDuration of the offer.
+
+This miscalculation will always result the `feeOfMaxDeadline` as `maxFee` because of how big the value is. No matter how long the loan extended, the fee will be paid as maximum fee.

+# owner address cannot be changed
+
+### Summary
+
+It is currently impossible to change ownership of the contracts `DebitaV3Aggregator` , `auctionFactoryDebita`, and `buyOrderFactory`.
+
+The current owner is stored in a state variable ` address public owner;` in each of the contracts mentioned above
+
+### Root Cause
+
+```solidity
+ function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ @> owner = owner;
+ }
+```
+The function above is implemented in each of the aforementioned contracts above and its responsible for changing the owner to a new address , however the part marked `@>` indicates that, when assigning a new address, It assigns the state variable `owner` back to itself. This means even if a new address is set , the owner address will still remain as the deployer ` owner = msg.sender;`

+# USDT approval reverts blocking loan extension and debt repayment
+
+### Summary
+
+The protocol intends to support USDT, but uses the IERC20 interface in `DebitaV3Loan::extendLoan()` and `DebitaV3Loan::payDebt()` functions to `approve` the lend offer when the lenders loan is perpetual. When approve is called with USDT as the principle token, the call will revert, block borrowers from extending their loan or paying their debt.
+
+### Root Cause
+
+The IERC20 interface expects a bool return value, but USDT doesn't return a bool which causes the revert.
+
+Here's the problematic line in payDebt():

+# Lender will Unable to Claim Their NFT Collateralized Loan
+
+### Summary
+
+The lender couldn't claim the collateral anymore if the lender call `DebitaV3Loan::claimCollateralAsLender` before the auction has been initialized even though the lender hasn't claim the collateral yet.
+
+
+### Root Cause
+
+In `DebitaV3Loan::claimCollateralAsLender`, if the lender wants to claim the NFT collateral then `DebitaV3Loan::claimCollateralAsNFTLender` is called. The function returning boolean value, it check 2 scenario where if the auction has been initialized or the acceptedOffers.length has to be 1 and auction not initialized. If the scenario is fulfilled then `true` will be returned, otherwise if the scenario isn't fulfilled then `false` will be returned. However, the boolean value being returned is useless as it not being used anywhere even `DebitaV3Loan::claimCollateralAsLender`.
+
+The issue is in `loanData._acceptedOffers[index].collateralClaimed = true;` line. The lender has been updated to claimed, doesn't matter if the lender has really claimed or not. If one of the lender of NFT collateralized loan call `DebitaV3Loan::claimCollateralAsLender` before the auction initialized for the particular NFT, then the lender simply can't claim the collateral anymore even after the auction has been initialized and the NFT has already sold.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L377

+# WBTC had not been accounted for its 8 decimals nature
+
+### Summary
+
+WBTC have 8 decimals on Arbitrum & Optimism & on Base chain as well.
+
+There are numerous functions which do calculations without regards to its 8 decimals nature and the perfect example to show you is `DebitaV3Loan::calculateInterestToPay()`.
+
+If I have to pay interest (APR - 2.35%, initialDuration - 7 days) on 0.009 WBTC which as writing this in Wednesday 20.11 is over $94.000 per BTC - so 0.009 will be ~$850.
+
+Let's say that I want to repay my debt the first day - 86 400 seconds
+
+The calculation will look as follows - `(1e8 * 0.009 * 235 / 10_000) * 86 400 / 31_536_000 = 57.96` (accounting for the decimal of course, not 57.96 bitcoins), which will **round down the amount** to 57 WBTC (accounting for the decimal), thus losing almost 2% of the interest that should've been paid to the lender, but it is being rounded down.
+
+### Root Cause
+
+Account for rounding in tokens are that not 18 decimals, such as WBTC in this example and the attack will be especially more prevalent when the lender is a perpetual one, so he will just lend the money and think about how he is getting the fees he deserves, but those 2% are more than significant to be accounted for and in the scenario I described, it will be 50 cents.
+
+Imagine those 50 cents or more how it will affect the perpetual if it is on for a year or more, it will accumulate and be more than $10 as time passes and more and more loans are repaid.
+
+### Internal pre-conditions
+
+The rounding down will happen in certain conditions, APR and amounts,
+ but is a real issue that will occur in the protocol when they're met.
+
+### External pre-conditions

+### Attack Path

+# Mixing of PriceFeed decimals could break protocol core functionalities
+
+### Summary
+
+A decimal precision mismatch between the price feeds used in the ``matchOrder`` contract can lead to incorrect calculations of borrower-to-principle ratios. Specifically, the issue arises in the ``getPriceFrom`` function when fetching prices from oracles with inconsistent decimal precision, such as Chainlink oracles that vary between 8 and 18 decimals. This inconsistency propagates through critical calculations in the matchOrder contract, leading to inaccurate loan terms, potential protocol insolvency, and failed transactions.
+
+The issue of inconsistent decimal precision from the ``getPriceFrom`` function directly impacts the calculation of loan-to-value ratios (``LTV``) . If oracles return prices with different decimal precisions and the logic does not properly account for these differences, it can cause incorrect ratios.
+
+### Root Cause
+
+The ``getThePrice`` function mistakenly assumes that all Chainlink price feeds have the same decimal precision. While most USD price feeds use 8 decimals, some, like the ``AMPL/USD`` feed, use 18 decimals.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L30
+```solidity
+ function getThePrice(address tokenAddress) public view returns (int) {
+ // falta hacer un chequeo para las l2
+ address _priceFeed = priceFeeds[tokenAddress];
+ require(!isPaused, "Contract is paused");
+ require(_priceFeed != address(0), "Price feed not set");
+ AggregatorV3Interface priceFeed = AggregatorV3Interface(_priceFeed);
+
+ // if sequencer is set, check if it's up
+ // if it's down, revert
+ if (address(sequencerUptimeFeed) != address(0)) {
+ checkSequencer();
+ }
+ (, int price, , , ) = priceFeed.latestRoundData();
+
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+ require(price > 0, "Invalid price");
+ @> return price;
+ }
+```
+The ``matchOrder`` contract fetches collateral and principle prices using the ``getPriceFrom`` function, relying on oracles provided by the borrower. For example:
+
+```solidity
+uint priceCollateral_BorrowOrder = getPriceFrom(
+ borrowInfo.oracle_Collateral,
+ borrowInfo.valuableAsset
+);
+uint pricePrinciple = getPriceFrom(
+ borrowInfo.oracles_Principles[indexForPrinciple_BorrowOrder[i]],
+ principles[i]
+);
+```
+These prices are used to calculate the ValuePrincipleFullLTVPerCollateral:
+
+```solidity
+uint ValuePrincipleFullLTVPerCollateral = (priceCollateral_BorrowOrder * 10 ** 8) / pricePrinciple;
+```
+The calculation assumes both ``priceCollateral_BorrowOrder`` and ``pricePrinciple`` have consistent decimal precision. However, if the oracles return prices with different decimals (e.g., 8 decimals for ``BTC/USD`` and 18 decimals for ``AMPL/USD``), the calculation produces incorrect results. This mismatch impacts the derived loan ratios and the borrower's borrowing capacity.

+### External pre-conditions

+_No response_
+
+### Impact
+
+1. **Underestimated Borrower Capacity**: Borrowers receive far fewer principle tokens than they should, leading to unfavorable loan terms and user dissatisfaction.
+2. **Overestimated Borrower Capacity**: If the mismatch leads to an overestimation, borrowers could over-leverage, causing the protocol to become undercollateralized and risking insolvency during liquidations.
+3. **Failed Transactions**: When the mismatch results in extreme values (e.g., pricePrinciple much larger than priceCollateral_BorrowOrder), the contract might:
+Revert due to invalid price checks (``require(priceCollateral_BorrowOrder != 0)``).
+
+### PoC
+
+**Consider the following Setup**
+
+- **Collateral**: BTC (borrowInfo.oracle_Collateral is a Chainlink oracle with 8 decimals).
+- **Principle**: AMPL (borrowInfo.oracles_Principles is a Chainlink oracle with 18 decimals).
+- **Loan-to-Value (LTV)**: 75% for AMPL as a principle.
+-
+**Input Prices**
+- ``priceCollateral_BorrowOrder`` = $$50,000 * 10⁸ (BTC/USD price from Chainlink oracle with 8 decimals).$$
+- ``pricePrinciple`` = $$1,500 * 10¹⁸ (AMPL/USD price from Chainlink oracle with 18 decimals).$$
+
+**Steps in Calculation**
+Calculate Full LTV Value:
+
+```solidity
+ValuePrincipleFullLTVPerCollateral = (priceCollateral_BorrowOrder * 10 ** 8) / pricePrinciple;
+```
+Substituting:
+```math
+(50,000 * 10⁸ * 10⁸) / (1,500 * 10¹⁸) = (50,000 * 10¹⁶) / (1,500 * 10¹⁸) = 0.0333.
+```
+- **Incorrect Result**: The mismatch in decimals drastically reduces the calculated value.
+- **Corrected Calculation**: Normalize ``priceCollateral_BorrowOrder`` to 18 decimals:
+
+$$priceCollateral_BorrowOrder = 50,000 * 10¹⁸.$$
+**Recompute**:
+```math
+ValuePrincipleFullLTVPerCollateral = (50,000 * 10¹⁸ * 10⁸) / (1,500 * 10¹⁸) = 33,333.33.
+```
+**Compute Loan Value: Using the incorrect value**:
+$$value = (ValuePrincipleFullLTVPerCollateral * LTV) / 10000;$$
+Substituting:
+
+$$(0.0333 * 75) / 10000 = 0.0000024975.$$
+**Correct Value**: $$(33,333.33 * 75) / 10000 = 2,500$$.
+
+
+### Mitigation
+
+Normalize price feed Decimal
+```solidity
+
+ uint8 decimals = IAggregatorV3Interface(_priceFeed).decimals();
+ if (decimals < 18) {
+ return uint256(price) * 10**(18 - decimals); // Scale up to 18 decimals
+ } else {
+ return uint256(price) / 10**(decimals - 18); // Scale down to 18 decimals
+ }
+ }

+# Malicious actor can DoS the whole lending functionality resulting in all lending offers being stucked
+
+### Summary
+
+Alice decides to do bad things today as she notices a vulnerability in the `DebitaLendOffer-Implementation.sol`.
+
+She has a lending offer which is not yet matched, but decides to cancel it via `cancelOffer()` purposefully - **cancellation doesn't remove the actual contract that is having the lending offer**, just changes some variables in the factory contract,
+and decrements the `activeOrdersCount`.
+
+She is then totally free to call `addFunds()` to add funds to her lend offer that was just deleted, but it actually just had it funds emptied and decremented `activeOrdersCount`, or said with other words - she can freely interact with it.
+
+There is a variable called `isActive`, which is set to `false`, but nowhere in `addFunds()` or `cancelOrder()` is it being checked, so it is not enforced, even thought it should.
+
+After Alice adds funds via `addFunds()`, she can call `cancelOrder()` a second time and again decrement `activeOrdersCount`.
+
+She can do that repeatedly till `activeOrdersCount` is equal to zero, even though numerous lending offers can exist, and they will most likely!
+
+This results in an underflow that will make cancellation of other users' lending offers impossible and breaking `acceptLendingOffer()` as well, because it is a function that still tries to call `deleteOrder()` to the factory contract, **which will render both cancellation and accepting of lending offers impossible** in the contract, resulting in stuck funds.
+
+### Root Cause
+
+The root cause is the lack of a logic that checks `isActive` boolean in `cancelOrder()` and `addFunds()`- I do not see any reason why it is set in cancelOrder() but not enforced in the functions that I mentioned.
+
+We can see that it is being set to [false](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L149) in cancelOrder(), but not checked against, so we can call cancelOrder() as much times as we want if we have funds in `availableAmount` in order to decrement till underflow is possible - leading to the impossibility of legitimate users cancelling orders as well as having their orders matched.
+
+All in all, calling those two functions should come up with a check in the beginning of the function that is require(isActive) to see if the lending offer is still active.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Alice creates a lending offer via the factory contract
+2. Alice calls `cancelOffer()` and get her initial tokens that she sent when she created the lending offer
+3. Alice then calls `addFunds()` to be able to invoke `cancelOffer()` again
+4. She repeats calling `addFunds()` and then `cancelOffer()` till she decrements the `activeOrdersCount` to 0
+5. Bob has his lending offer matched, but `acceptLendingOffer()` calls at the of it `deleteOrder()`, which will try to do: 0 - 1, which as we know in Solidity is an underflow and will result in a revert.
+
+### Impact
+
+Lending offers can't be accepted and matched and lending offers can't be cancelled.
+
+Basically any function which calls `deleteOrder()` will be uncallable, resulting in breaking core protocol logic and resulting in a 100% loss of funds.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Implement `isActive` checks in the functions that are needed - `addFunds()` and `cancelOffer()`

+# Missing Checks for Min/Max Price in Chainlink Oracle
+
+### Summary
+
+A lack of validation for returned price bounds in the `getThePrice` function will cause a mispricing vulnerability for the protocol as malicious actors or unforeseen price feed anomalies will allow invalid prices to propagate within the system.
+
+### Root Cause
+
+In `DebitaChainlink.sol:30` at `getThePrice()`, the implementation does not include checks for `minAnswer` and `maxAnswer` values from the Chainlink Aggregator. This oversight allows the system to accept prices that are either too low (e.g., zero or near-zero during crashes) or excessively high.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L30-L47
+
+### Internal pre-conditions
+
+1. **Admin needs to set the price feed** to a valid address through the `setPriceFeeds()` function.
+2. **isFeedAvailable[_priceFeed]** must be set to `true` for the price feed.
+
+
+### External pre-conditions
+
+1. The Chainlink price feed needs to provide a value below the valid `minAnswer` or above the `maxAnswer` due to a market anomaly or malfunction.
+2. The protocol consuming the price feed must rely on the invalid price without additional validation.
+
+### Attack Path
+
+1. A malicious actor influences the underlying market or price feed in such a way that the Chainlink oracle provides an out-of-bounds price (e.g., a "crash" price).
+2. The affected Chainlink price feed propagates the invalid price to the `getThePrice()` function.
+3. The protocol using this price for calculations, transactions, or collateral valuation misprices assets, causing financial loss or destabilization.
+
+### Impact
+
+If a situation like LUNA hack happens then the oracle will return the minimum price and not the crashed price.
+The **protocol users** suffer from potential financial loss due to mispricing or incorrect collateral/liquidation calculations. The **attacker** may profit from the system's reliance on invalid prices, leading to significant economic damage or exploitation.
+
+### PoC
+
+The function did not check for the min and max price that can be retrieved from the Chainlink Aggregator
+
+### Mitigation
+
+To avoid consuming stale prices when Chainlink freezesthe protocole needs to introduce explicit checks for `minAnswer` and `maxAnswer` values provided by the Chainlink Aggregator. Below is a proposed solution:

+# Sequencer Downtime Enables Below-Market Dutch Auction Purchases
+
+### Summary
+
+The lack of sequencer uptime validation in the Dutch auction mechanism will cause significant financial losses for sellers as malicious buyers can wait for sequencer downtime to purchase NFTs at artificially decreased prices when the sequencer resumes.
+
+### Root Cause
+
+In `auctions/Auction.sol`, the Dutch auction price calculation relies solely on `block.timestamp` without any sequencer uptime validation:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3-obou07/blame/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L228-L241
+
+```solidity
+function getCurrentPrice() public view returns (uint256) {
+ dutchAuction_INFO memory m_currentAuction = s_CurrentAuction;
+
+ if (block.timestamp >= m_currentAuction.endBlock) {
+ return m_currentAuction.floorAmount;
+ }
+
+ uint256 elapsed = block.timestamp - m_currentAuction.initialBlock;
+ uint256 discount = elapsed * m_currentAuction.tickPerBlock;
+
+ return m_currentAuction.initAmount - discount;
+}
+```
+
+The issue arises because:
+1. Price decreases linearly based on `block.timestamp`
+2. During sequencer downtime, `block.timestamp` continues to advance
+3. No validation of sequencer status or timestamp gaps
+
+
+
+### Internal pre-conditions
+
+1. An active Dutch auction needs to exist in the protocol
+2. The auction's initial price needs to be significantly higher than the floor price
+3. The auction duration needs to be long enough to potentially encounter sequencer downtime
+
+
+### External pre-conditions
+
+1. L2 sequencer needs to go down for a significant period (e.g., >1 hour)

+
+### Impact
+
+The protocol and sellers suffer from unfair NFT sales at artificially low prices. Attackers can gain significant discounts by exploiting sequencer downtime to purchase NFTs at prices far below market value.

+# Conflicting variable names render changeOwner function in DebitaV3Aggregator.sol ineffective
+
+### Summary
+
+The name of the variable in the `changeOwner(address owner)` function's input parameter is incorrect, as it corresponds exactly to the `owner` state variable in the contract. This causes the function not to perform the require as expected and not to modify the value of `owner`.
+
+### Root Cause
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682
+In DebitaV3Aggregator.sol::changeOwner() function, there is a name conflict. Indeed, the local variable `owner` (the function parameter) hides the state variable `owner` declared at the top of the contract.
+The require doesn't check if the `msg.sender` is the real `owner`(state variable) but if the `owner` local variable of the function is equal to `msg.sender`.
+The assignment owner = owner simply assigns the value of the `owner` local variable to itself, without ever modifying the contract's `owner` state variable.
+
+### Attack Path
+
+Owner of the contract tries to changes the variable `owner` using `changeOwner()`.
+
+### Impact
+
+The contract's `owner` state variable cannot be modified.
+
+### Mitigation
+
+Change the name of the local variable used in the function.
+Example:
+```solidity
+ function changeOwner(address newOwner) public {
+ require(msg.sender == owner, “Only owner”);
+ require(deployedTime + 6 hours > block.timestamp, “6 hours passed");
+ owner = newOwner;}

+# Improper ownership minting will show the ownership of lender as borrower and vice versa.
+
+### Summary
+
+The `DebitaLoanOwnerships` contract is used for minting ownerships to lenders and borrowers respectively in order to show their ownership.
+The contract uses an odd-even logic for the same, where odd `tokenId` will return a `tokenURI` specifically for lenders and even would return for borrowers.
+```solidity
+ function tokenURI(
+ uint256 tokenId
+ ) public view override returns (string memory) {
+ require(tokenId <= id, "Token Id does not exist");
+ IDebitaAggregator _debita = IDebitaAggregator(DebitaContract);
+ address loanAddress = _debita.getAddressById(tokenId);
+ string memory _type = tokenId % 2 == 0 ? "Borrower" : "Lender"; <@ - Odd for lender and even for borrower.
+```
+The issue lies with the way we use the [`DebitaLoanOwnerships::mint`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLoanOwnerships.sol#L34) function in the [`DebitaV3Aggregator::matchOffersV3`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274)
+```solidity
+function matchOffersV3(
+ address[] memory lendOrders, <@ - // Multiple orders can be passed here
+ uint[] memory lendAmountPerOrder,
+ uint[] memory porcentageOfRatioPerLendOrder,
+ address borrowOrder,
+ address[] memory principles,
+ uint[] memory indexForPrinciple_BorrowOrder,
+ uint[] memory indexForCollateral_LendOrder,
+ uint[] memory indexPrinciple_LendOrder
+ ) external nonReentrant returns (address) {
+// ... Rest of the code...
+ for (uint i = 0; i < lendOrders.length; i++) {
+
+// ... Rest of the code...
+
+ // mint ownership for the lender
+ uint lendID = IOwnerships(s_OwnershipContract).mint(lendInfo.owner); <@ - // Lender minting happens in a for loop without considering `tokenId % 2 == 1` has to be sufficed.
+ offers[i] = DebitaV3Loan.infoOfOffers({
+ principle: lendInfo.principle,
+ lendOffer: lendOrders[i],
+ principleAmount: lendAmountPerOrder[i],
+ lenderID: lendID,
+ apr: lendInfo.apr,
+ ratio: ratio,
+ collateralUsed: userUsedCollateral,
+ maxDeadline: lendInfo.maxDuration + block.timestamp,
+ paid: false,
+ collateralClaimed: false,
+ debtClaimed: false,
+ interestToClaim: 0,
+ interestPaid: 0
+ });
+ getLoanIdByOwnershipID[lendID] = loanID;
+ lenders[i] = lendInfo.owner;
+ DLOImplementation(lendOrders[i]).acceptLendingOffer(
+ lendAmountPerOrder[i]
+ );
+ } // loop exited
+ // ...Rest of the code...
+ uint borrowID = IOwnerships(s_OwnershipContract).mint(borrowInfo.owner); <@ - // Minting happens without considering `tokenId % 2 == 0` has to be sufficed.
+ // ...Rest of the code...
+```
+Due to the loop, when the number of lend orders are greater than 1, it would mint incorrect ownerships to the even numbered order.
+Similarly, in case of even number of lend orders (greater than 1), would mint incorrect ownership for borrower.
+This is clearly not an intended flow, hence would affect the user's ownership and off-chain data.
+
+### Root Cause
+
+In [`DebitaAggregatorV3.sol:502`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L502) where minting happens inside a for loop without considering the logic mentioned on [`DebitaLoanOwnerships.sol:84`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLoanOwnerships.sol#L84)
+```string memory _type = tokenId % 2 == 0 ? "Borrower" : "Lender";```
+
+Similarly, in [`DebitaAggregatorV3.sol:577`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L577) minting takes place without considering the above logic.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Anyone willing to match orders for borrowers and lenders need to call the [`matchOffersV3`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274) with **more than 1** lend order.
+
+### Impact
+
+1. Incorrect minting of token would happen as the tokenURI will return metadata as a borrower to a lender and vice versa.
+2. The function [`buildImage`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLoanOwnerships.sol#L53) will return borrower's image url to a lender and vice versa.
+3. This would confuse users and the off-chain mechanism which would show this data to the users.
+
+### PoC
+
+The below test case was added in `MultiplePrinciples.t.sol`
+```solidity
+ function testIncorrectOwnershipMint() public {
+ address[] memory principles = allDynamicData.getDynamicAddressArray(1);
+ address[] memory collateral = allDynamicData.getDynamicAddressArray(1);
+ address[] memory incentiveToken = allDynamicData.getDynamicAddressArray(
+ 1
+ );
+
+ bool[] memory isLend = allDynamicData.getDynamicBoolArray(1);
+ uint[] memory amount = allDynamicData.getDynamicUintArray(1);
+ uint[] memory epochs = allDynamicData.getDynamicUintArray(1);
+
+ principles[0] = AERO;
+ collateral[0] = USDC;
+ incentiveToken[0] = AERO;
+ isLend[0] = true;
+ amount[0] = 100e18;
+ epochs[0] = 2;
+ deal(AERO, address(this), 10000e18);
+ incentivesContract.whitelListCollateral(AERO, USDC, true);
+
+ IERC20(AERO).approve(address(incentivesContract), 1000e18);
+ incentivesContract.incentivizePair(
+ principles,
+ incentiveToken,
+ isLend,
+ amount,
+ epochs
+ );
+ vm.warp(block.timestamp + 15 days);
+ matchOffers(); // Matches 3 lenders with a borrow order
+
+ // Starts from 1
+ address ownerFirst = ownershipsContract.ownerOf(1);
+ address ownerSecond = ownershipsContract.ownerOf(2);
+ address ownerThird = ownershipsContract.ownerOf(3);
+ address ownerFourth = ownershipsContract.ownerOf(4);
+
+ // The DebitaLoanOwnerships.sol mentions that the owner of the token is the borrower if the index is even and the lender if the index is odd
+ assertEq(ownerFirst, firstLender); // 1 % 2 == 0 ? "Borrower" : "Lender" == "Lender"
+ assertEq(ownerSecond, secondLender); // 2 % 2 == 0 ? "Borrower" : "Lender" == "Borrower" <- Incorrectly assigned borrower's tokenURI (type and buildImage will be incorrect as well)
+ assertEq(ownerThird, thirdLender); // 3 % 2 == 0 ? "Borrower" : "Lender" == "Lender"
+ assertEq(ownerFourth, borrower); // 4 % 2 == 0 ? "Borrower" : "Lender" == "Borrower"
+
+}
+```
+
+This clearly shows a lender getting borrower's NFT minted where tokenURI would return borrower's metadata.
+
+### Mitigation
+
+It is recommended to pass `_tokenType` directly in the parameter of mint and maintain a mapping for the same.

+# USDT incompatible with DebitaIncentives contract
+
+### Summary
+
+The protocol intends to support USDT, but uses the IERC20 interface in the `DebitaIncentives` contract to:
+1. `transferFrom()` the incentive depositer to the incentives contract in `incentivizePair()`
+2. `transfer()` incentives from the incentives contract to the incentive receiver in `claimIncentives()`
+
+Both transfers will always revert when the incentive token is USDT.
+
+
+
+### Root Cause
+
+The IERC20 interface expects a bool return value, but USDT doesn't return a bool which causes the revert.
+
+Here's the problematic line in `incentivizePair()`:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L269-L273
+
+Here's the problematic line in `claimIncentives()`:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L203
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+1. User wants to use USDT as a token incentive
+
+### Attack Path
+
+1. A user wants to use USDT as an incentive token
+2. They call `incentivizePair()`, but the call reverts due to the root cause mentioned above.
+3. Although `claimIncentives` would also revert when USDT is the incentive, this would be impossible because there would never be any USDT to claim because noone can call `incentivizePair` with USDT.
+
+### Impact
+
+USDT cannot be used as an incentive token.
+
+### PoC
+
+_No response_
+
+### Mitigation
+

+# Index Zero Collision in DebitaBorrowOffer-Factory Will Break Core Order Management System
+
+### Summary
+
+A critical design flaw in the order indexing system will cause catastrophic order management failures and potential permanent fund lockups, as the system cannot distinguish between valid and deleted orders due to both sharing index 0. This fundamentally breaks the protocol's ability to manage borrow positions reliably.the same issue is in the `DebitaLendOfferFactory` and ``buyOrderFactory``
+
+### Root Cause
+
+In `DebitaBorrowOffer-Factory.sol:171` the order management system has a critical design flaw in how it handles order indexing:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L99-L105
+```solidity
+function deleteBorrowOrder(address _borrowOrder) external onlyBorrowOrder {
+ uint index = borrowOrderIndex[_borrowOrder];
+ borrowOrderIndex[_borrowOrder] = 0; // Critical: Reuses index 0 for deleted orders
+ ...
+}
+```
+
+The system uses index 0 for two conflicting purposes:
+1. Identifying the first valid order in the system
+2. Marking deleted orders
+
+This dual use of index 0 creates an unresolvable state confusion in the order tracking system.
+
+### Internal pre-conditions
+
+1. Protocol needs to have at least one active borrow order with `borrowOrderIndex[orderA] = 0`
+2. Protocol needs to have a second borrow order with `borrowOrderIndex[orderB] = 1`
+3. System's `activeOrdersCount` must be greater than `1`
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+Let's say we have two orders in the system:
+
+1. Order A (First Order):
+ - Index: 0
+ - Collateral: 10 ETH
+ - Status: Active
+ - Loan Amount: 5000 USDC
+
+2. Order B (Second Order):
+ - Index: 1
+ - Collateral: 20 ETH
+ - Status: Active
+ - Loan Amount: 10000 USDC
+
+When Order B is deleted:
+- Both orders now have index 0
+- System can't tell if Order B's 20 ETH position is really deleted
+- Interest calculations might still apply to Order B
+- Order A's 10 ETH position might be treated as invalid
+- Total affected funds: 30 ETH and 15000 USDC at risk
+
+### Impact
+
+ - Order tracking becomes unreliable
+ - Wrong interest calculations
+ - Invalid liquidations
+
+### PoC
+
+_No response_
+
+### Mitigation

+# creating borrow orders with NFT collaterals may revert
+
+### Summary
+
+When `createBorrowOrder()` is called, the factory
+- initialises the `borrowOffer` with the `_collateralAmount`
+- transfers the NFT to the `borrowOffer` implementation contract and then goes on to check that the the balance of the `borrowOffer` is actually enough to cover the `_collateralAmount`
+
+### Root Cause
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L143-L144
+
+
+The problem is that, if the `_collateral` is an NFT, the function may revert because a `IERC20` is being used to call an `IERC721` contract.
+And as such, although the `IERC721` interface implements the `balanceOf()` function signature, but the return value is not guaranteed to be accurate and as such the check on L144 below may revert
+
+```solidity

+# Bad actors will steal control of users' borrow positions by deleting them
+
+### Summary
+
+A missing ownership check in the borrow order factory will let malicious users delete anyone's borrow positions, putting users' funds at risk. Any user who has created even a tiny borrow order can delete other users' much larger positions, potentially causing them to lose access to their collateral.the same issue is in the `DebitaLendOfferFactory.sol`
+
+### Root Cause
+
+In `DebitaBorrowOffer-Factory.sol:171`, the contract trusts any borrow order to delete other orders - it's like giving everyone with a library card the power to burn anyone else's books:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L162-L177
+```solidity
+
+ modifier onlyBorrowOrder() {
+ require(isBorrowOrderLegit[msg.sender], "Only borrow order");
+ _;
+ }
+```
+so any legit user can delete the other users
+```solidity
+function deleteBorrowOrder(address _borrowOrder) external onlyBorrowOrder {
+ uint index = borrowOrderIndex[_borrowOrder];
+ borrowOrderIndex[_borrowOrder] = 0;
+ ...
+}
+```
+
+### Internal pre-conditions
+
+1. Attacker needs to create any small borrow order to get their "deletion powers" (`isBorrowOrderLegit[attackerOrder] = true`)
+2. A victim needs to have a juicy borrow position with at least 50k worth of tokens as collateral
+3. The protocol needs to have at least 2 active orders (pretty much always true)
+
+### External pre-conditions
+
+1. Target token price needs to be high enough to make the attack worth the gas (e.g., token worth at least $50)
+2. Network shouldn't be too congested (gas < 100 gwei) so the attack stays profitable
+
+
+### Attack Path
+
+### Initial Setup
+1. Attacker initializes position:
+ - Creates minimal borrow order (≈1,000 token value)
+ - Gains legitimate system access
+ - Minimal capital requirement reduces attack cost
+
+### Exploitation Process
+2. Position Analysis:
+ - Scans protocol for high-value positions
+ - Targets positions with significant locked collateral (>100k token value)
+ - Identifies vulnerable orders without proper access control
+
+3. Attack Execution:
+ - Attacker invokes `deleteBorrowOrder()` function
+ - Uses their legitimate small position as access point
+ - Targets identified high-value positions
+
+
+### Impact
+
+ Position Compromise:
+ - Target position is deleted without authorization
+ - Locked collateral becomes vulnerable
+ - Position owner loses control of their assets
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+```solidity
+// @audit-fix Implement proper access control
+function deleteBorrowOrder(address _borrowOrder) external {
+ DBOImplementation order = DBOImplementation(_borrowOrder);

+# USDT Approval Pattern Causes DOS in Loan Operations
+
+### Summary
+
+The direct approval pattern used in DebitaV3Loan.sol will cause denial of service (DOS) for USDT-based loans as USDT requires allowance to be reset to 0 before setting a new value. This affects core loan operations including extensions and interest payments.
+
+
+### Root Cause
+
+In `DebitaV3Loan.sol`, direct approve calls are made without following USDT's required approval pattern:
+
+```solidity
+// Line 242:
+IERC20(offer.principle).approve(address(lendOffer), total);
+
+// Line 661:
+IERC20(offer.principle).approve(
+ address(lendOffer),
+ interestOfUsedTime - interestToPayToDebita
+);
+```
+
+The issue arises because:
+1. USDT requires allowance to be reset to 0 before setting a new non-zero value
+2. Contract uses direct approve calls without resetting
+3. No handling of USDT's specific approval requirements
+4. Multiple functions affected due to reuse of approval pattern
+
+### Internal pre-conditions
+
+1. Loan must use USDT as principle token
+2. Contract must have an existing non-zero USDT allowance
+3. User must attempt to perform an operation requiring approval (extend loan, pay interest)
+
+### External pre-conditions
+
+None - USDT's behavior is consistent across all networks
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+The protocol suffers from severe functionality loss for USDT-based loans:
+
+1. Loan Extensions: Blocked
+2. Interest Payments: Failed
+
+
+This effectively makes the protocol unusable for one of the most common stablecoins in DeFi.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+1. Replace direct approve calls with SafeERC20's pattern

+# Lack of Dynamic Adjustment for Maximum Interest Rate Based on Chain Parameters
+
+### Summary
+
+A fixed maximum interest rate (_maxInterestRate) in the smart contract may cause **incorrect interest rates or loan denial** for **borrowers and lenders** as **the system cannot account for varying block times across different chains.**
+
+### Root Cause
+
+In the function **`createBorrowOrder`**, the **_maxInterestRate** parameter is not dynamically adjusted based on the block time of the chain. This creates a mismatch between the intended interest rate and its actual effect due to varying chain environments.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L75
+
+Example:
+If `_maxInterestRate = 0.01`, it translates differently depending on block time:
+- Ethereum (12 seconds/block): ≈73% annual rate
+- Binance Smart Chain (3 seconds/block): ≈292% annual rate
+
+This disparity can unintentionally lead to excessive interest rates or underperformance of loans.
+
+### Internal pre-conditions
+
+1. The borrower initializes a borrow order with a fixed `_maxInterestRate`.
+2. The chain's block time is significantly different from the assumed block time in the contract's logic.
+
+### External pre-conditions
+
+1. The chain’s block time (external protocol factor) does not match the assumed average block time.
+2. The borrowing or lending ecosystem relies on consistent interest rate calculations.
+
+### Attack Path
+
+This issue is conceptual, but the lack of adjustments may create unfavorable outcomes:
+1. A borrower sets a `_maxInterestRate` they find acceptable (e.g., 5%).
+2. Due to shorter block times, the actual annualized interest rate becomes far higher than intended.
+3. Borrowers unknowingly enter unfavorable loan agreements or lenders receive lower returns.
+
+### Impact
+
+- **Borrowers** may face **unexpectedly high interest rates**, discouraging platform use.
+- **Lenders** may find it difficult to assess the profitability of their loans.
+- The platform risks **loss of trust and adoption**.
+
+### PoC
+
+The example below demonstrates how the fixed `_maxInterestRate` causes an unintended annualized interest rate on chains with varying block times:
+
+```solidity
+// Example borrow order creation
+createBorrowOrder(
+ ...
+ _maxInterestRate = 0.005 ether, // 0.5% per block
+ _duration = 30 days
+);
+```
+Assume `_maxInterestRate` is interpreted as **0.5% per block**:
+1. Ethereum: Annual rate ≈ 157% (12 sec/block)
+2. Binance Smart Chain: Annual rate ≈ 630% (3 sec/block)
+
+
+### Mitigation
+
+1. Dynamically calculate and enforce **_maxInterestRate** based on the chain's block time:
+ ```solidity
+ uint chainAdjustedRate = (_maxInterestRate * averageBlockTime) / expectedBlockTime;
+ ```
+ Use this adjusted rate for calculations.
+
+2. Introduce a configuration function to allow protocol admins to set the expected block time for the target chain.
+
+3. Validate interest rates dynamically in **`createBorrowOrder`** to ensure they align with protocol limits:
+ ```solidity
+ require(adjustedRate <= protocolMaxRate, "Interest rate exceeds protocol limits");
+ ```
+
+This ensures the protocol remains chain-agnostic and fair for all participants.

+# the owner can't upgrade the contract because of Immutable Proxy Implementation
+
+### Summary
+
+The immutable implementation design in the proxy contract will cause potential security risks for all users as malicious actors will be able to exploit any discovered vulnerabilities that cannot be patched due to the inability to upgrade the contract logic
+
+### Root Cause
+
+In `DebitaProxyContract.sol:6-13` the implementation address is set only in the constructor with no upgrade mechanism:
+
+```solidity
+constructor(address _logic) {
+ bytes32 implementationPosition = bytes32(
+ uint256(keccak256("eip1967.implementationSlot")) - 1
+ );
+ assembly {
+ sstore(implementationPosition, _logic)
+ }
+}
+```
+
+This design choice to make the implementation immutable is a mistake as it prevents any future updates, including critical security patches.
+
+### Internal pre-conditions
+
+1. Contract needs to be deployed with initial implementation address
+2. Any user needs to interact with proxy contract functionality
+3. A vulnerability needs to be discovered in the implementation logic
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Attacker discovers a vulnerability in the implementation contract
+2. Due to immutable implementation, the protocol cannot deploy a fix
+3. Attacker exploits the vulnerability affecting all users of the proxy
+4. Protocol is forced to deploy entirely new contracts
+5. Users must manually migrate to new contracts, risking funds during migration
+
+
+### Impact
+
+The protocol and its users suffer from:
+- Inability to patch security vulnerabilities
+- Forced contract redeployments
+- Expensive and risky migration processes
+- Potential complete loss of funds if critical vulnerabilities are discovered
+- Limited protocol evolution and feature updates
+
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Implement UUPS (Universal Upgradeable Proxy Standard)

+# Using TransferFrom() instead of safeTransferFrom() can cause a loss of funds
+
+### Summary
+
+The ERC20.transfer() and ERC20.transferFrom() functions return a boolean value indicating success. This parameter needs to be checked for success. Some tokens do not revert if the transfer failed but return false instead.
+
+### Root Cause
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L203
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L269
+The `claimIncentives()` and `incentivizePair()` functions use ERC20.transfer() and ERC20.transferFrom().
+Some tokens (like USDT) have their transfer/ transferFrom function return void instead of a success boolean. Calling these functions with the correct EIP20 function signatures may fail without reverting.
+
+
+### Impact
+
+Possibility that the transfer of funds fails and does not return an error, so the function continues as if the transfer was successful.
+This results in a loss of funds for the user when he tries to claim his incentives, and also a loss of incentives for the various Pair when the user tries to add them.
+
+
+### Mitigation
+
+Use OpenZeppelin's SafeERC20 versions with the `safeTransfer()` and `safeTransferFrom()` functions that handle the return value check.

+# Incentive Creator's Tokens Permanently Locked in Zero-Activity Epochs
+
+### Summary
+
+The lack of token recovery mechanism in DebitaIncentives.sol will cause permanent loss of incentive tokens for incentive creators as tokens remain locked in the contract during epochs with zero lending/borrowing activity.
+
+### Root Cause
+
+In DebitaIncentives.sol, the incentivizePair function transfers tokens to the contract without any recovery mechanism:
+
+```solidity
+// transfer the tokens
+IERC20(incentivizeToken).transferFrom(
+ msg.sender,
+ address(this),
+ amount
+);
+
+// add the amount to the total amount of incentives
+if (lendIncentivize[i]) {
+ lentIncentivesPerTokenPerEpoch[principle][
+ hashVariables(incentivizeToken, epoch)
+ ] += amount;
+} else {
+ borrowedIncentivesPerTokenPerEpoch[principle][
+ hashVariables(incentivizeToken, epoch)
+ ] += amount;
+}
+```
+
+This means that incentive creators can only deposit incentives for epochs that haven't started yet, and the incentives are locked in the contract until the epoch ends. Once tokens are transferred, they become permanently locked if no activity occurs in that epoch. This is a serious design flaw since market conditions are unpredictable and zero-activity epochs are likely to occur.
+
+### Internal pre-conditions
+
+1. Incentive creator needs to call `incentivizePair()` to deposit incentive tokens for a future epoch
+2. `totalUsedTokenPerEpoch[principle][epoch]` needs to be exactly 0
+3. No users perform any lending or borrowing actions during the specified epoch
+
+
+### External pre-conditions
+
+1. Market conditions lead to zero lending/borrowing activity during the incentivized epoch
+
+### Attack Path
+
+1. Incentive creator calls `incentivizePair()` to set up incentives for a future epoch, transferring tokens to the contract
+2. The epoch passes with no lending or borrowing activity
+3. No users can claim the incentives as there are no qualifying actions (`lentAmountPerUserPerEpoch` and `borrowAmountPerEpoch` remain 0)
+4. The tokens remain permanently locked in the contract as there is no withdrawal or recovery mechanism
+
+### Impact
+
+The incentive creators suffer a complete loss of their deposited tokens for that epoch. The tokens become permanently locked in the contract with no mechanism for recovery or redistribution to future epochs. This could lead to significant financial losses.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+ Add a recovery mechanism that allows incentive creators to withdraw unclaimed tokens after an epoch ends. This should only be possible if the epoch had zero activity.

+# Interest Rate Cap Issue in DBOFactory Smart Contract
+
+### Summary
+
+The logic for enforcing a maximum interest rate on borrow orders in the `DBOFactory` contract doesn't properly handle cases where utilization exceeds 100%, leading to the potential for interest rates to exceed the maximum allowable rate and cause reverts. This will prevent borrow orders from being created or processed, potentially locking user funds.
+
+### Root Cause
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L75
+
+- In the `DebitaBorrowOffer-Factory.sol` contract, the logic to enforce a maximum interest rate (`_maxInterestRate`) during borrow order creation does not account for situations where reserves exceed cash. As a result, when the utilization rate exceeds 100%, the calculated interest rate can exceed the maximum specified rate, causing the transaction to fail with a revert due to the check on the interest rate exceeding the max allowable rate.
+
+### Internal pre-conditions
+
+1. The `reserves` in the protocol are greater than the available cash, causing the utilization rate to exceed 100%.
+2. The user creates a borrow order with a specified `_maxInterestRate` that is higher than the calculated interest rate.
+3. The contract attempts to calculate the interest rate during the execution of `accrueInterest` or a similar function, leading to a possible revert.
+
+### External pre-conditions
+
+ The user specifies a `_maxInterestRate` that is too high, without ensuring that it is within acceptable bounds.
+
+### Attack Path
+
+1. The user creates a borrow order in the , ` specifying a `_maxInterestRate` greater than the calculated interest rate.
+2. During the `accrueInterest` function or another borrow-related function, the utilization rate is calculated, but reserves exceed the available cash, causing the utilization to go above 100%.
+3. The calculated interest rate exceeds the maximum allowable interest rate, triggering the `require(_maxInterestRate <= maxAllowedApr, "Max APR exceeds allowed limit")` check.
+4. The transaction fails, preventing the borrow order from being created and locking the user's funds.
+
+### Impact
+
+The protocol suffers from the inability to process borrow orders when the utilization exceeds 100%, as the interest rate exceeds the maximum allowed. This leads to failed transactions, preventing users from borrowing, repaying, or interacting with the protocol.
+
+
+### PoC
+
+```solidity
+uint maxAllowedApr = 28.5%; // Use a fixed or dynamic cap for maximum APR
+require(_maxInterestRate <= maxAllowedApr, "Max APR exceeds allowed limit");
+
+uint borrowRate = calculateBorrowRate();
+uint cappedRate = borrowRate > maxAllowedApr ? maxAllowedApr : borrowRate;
+```
+
+In this code, the maximum APR is capped at a fixed or dynamic value to avoid exceeding the allowed interest rate, even when utilization exceeds 100%.
+
+### Mitigation
+
+1. **Cap Interest Rate on Borrow Order Creation:** When a borrow order is created, ensure the `_maxInterestRate` is capped and does not exceed a fixed maximum limit, even when utilization exceeds 100%.
+
+2. **Recalculate and Cap Interest Rate:** In the functions responsible for calculating the interest rate, ensure that the rate is capped before it is used, like in the example provided.
+
+3. **Safety Check Before Interest Rate Calculation:** Implement a check to verify that the utilization rate is within acceptable bounds. If it exceeds 100%, either revert the transaction or normalize the utilization rate to ensure the interest rate does not become unreasonably high.

+In three of the contracts:

+
+there are `changeOwner` functions which with the current implementations will not actually change the owner if being called within the first 6 hours of deployment.
+
+### Root Cause
+
+In the following contracts:
+
+- [buyOrderFactory.sol:186](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol?plain=1#L186)

+
+the `changeOwner` function:
+
+```solidity
+ function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+```
+
+is using the same naming for the parameter `address owner` as for the state variable `owner`.
+
+Since the function parameter `owner` has the same name as a state variable, the local variable (parameter) will overshadow the state variable within the function's scope. The reference to the variable inside the function will refer to the local variable rather than the state variable which will lead to unexpected behavior and will break the protocol's intention for the `owner` to be able to update the `owner` state variable within those 6 hours after deployment.
+
+### Internal pre-conditions
+
+1. `owner` needs to call the `changeOwner` function within 6 hours of deployment.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+The three protocols using the same implementation of the `changeOwner` function are not actually able to change the existing `owner` when the function is being called, thus breaking the intended protocol functionality and behavior.
+
+### PoC
+
+With the current implementation the following test will fail and revert:
+
+```solidity
+// SPDX-License-Identifier: MIT
+pragma solidity ^0.8.0;
+
+import {Test, console} from "forge-std/Test.sol";
+import {Audit} from "../src/Audit.sol";
+
+contract ShadowingTest is Test {

+ address public initialOwner;
+ address public newOwner;
+
+ function setUp() external {

+ initialOwner = address(this); // The deployer is the initial owner
+ newOwner = address(0x123);
+ }
+
+ function testOwnerUpdated() public {

+
+ vm.prank(initialOwner);
+ auditContract.changeOwner(newOwner);
+
+ assertEq(auditContract.owner(), newOwner);
+ }
+}
+
+```
+
+When using one of the mitigation proposed below, the test will pass.
+
+Mitigation:
+
+```solidity
+ function changeOwner(address newOwner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = newOwner;
+ }
+
+```
+
+### Mitigation
+
+1. Changing the state variable names, following the convention with an `s_` suffix: `s_owner` and rewrite the setting of the `owner` line:
+
+```solidity
+ function changeOwner(address owner) public {
+ require(msg.sender == s_owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ s_owner = owner;
+ }
+```
+
+2. Rename just the function parameter such as `newOwner` and rewrite the setting of the `owner` line:
+
+```solidity
+ function changeOwner(address newOwner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = newOwner;
+ }

+# [M-4]: The `manager` variable in the `getDataFromUser` function is shadowed potentially changing the function intended functionality
+
+### Summary
+
+In two contracts:
+
+- [Aerodrome/Receipt-veNFT.sol:204](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/veNFTS/Aerodrome/Receipt-veNFT.sol?plain=1#L204)

+
+the function `getDataFromUser` uses a function parameter `address manager` and a local variable `address manager = _vaultContract.managerAddress();` leading to the local variable shadowing the function parameter.
+
+### Root Cause
+
+In [Aerodrome/Receipt-veNFT.sol:204](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/veNFTS/Aerodrome/Receipt-veNFT.sol?plain=1#L204)
+
+uses the same names for both the parameter and a variable in `getDataFromUser` function thus potentially changing the behavior since in the first part of the function the parameter is being used for calculations and after the shadowing occurs the local parameter is used for further calculations.
+
+```solidity
+ function getDataFromUser(
+@> address manager,
+ uint fromIndex,
+ uint stopIndex
+ ) external view returns (receiptInstance[] memory) {
+ uint amount = balanceOfManagement[manager] > stopIndex
+ ? stopIndex
+ : balanceOfManagement[manager];
+
+ veNFT veContract = veNFT(nftAddress);
+ receiptInstance[] memory nftsDATA = new receiptInstance[](
+ amount - fromIndex
+ );
+
+ for (uint i; i + fromIndex < amount; i++) {
+ uint nftID = ownedTokens[manager][i + fromIndex];
+ IVotingEscrow.LockedBalance memory _locked = veContract.locked(
+ nftID
+ );
+ address vault = veContract.ownerOf(nftID);
+ veNFTVault _vaultContract = veNFTVault(vault);

+ underlying: _underlying,
+ OwnerIsManager: currentOwnerOfReceipt == manager
+ });
+ }
+ return nftsDATA;
+ }
+```
+
+### Internal pre-conditions
+
+1. The `getDataFromUser` function should be called.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+Potentially this could change some of the protocol behavior and receipt data setup for the user when calculations are made with the `manager` parameter in the beginning of the function and afterwards the calculations are made with the `manager` variable retrieved from:
+
+```solidity
+address manager = _vaultContract.managerAddress();
+```
+
+Shadowing the variable could lead to incorrect comparisons. This issue could also introduce subtle bugs, especially if any changes are made to how `manager` is used in the future.
+
+If manager inside the loop refers to the vault manager (managerAddress), and it's shadowed, the code might mistakenly compare `currentOwnerOfReceipt` to the wrong address.
+
+If the wrong comparison is made, it could either:
+**Allow unauthorized withdrawals**: Another user could use the asset (receipt), even if they are not the legitimate manager.
+**Prevent valid withdrawals**: The correct manager could be blocked from performing operations because the comparison logic is flawed.
+
+```solidity
+nftsDATA[i] = receiptInstance({
+ receiptID: receipt,
+ attachedNFT: nftID,
+ lockedAmount: uint(int(_locked.amount)),
+ lockedDate: _locked.end,
+ decimals: _decimals,
+ vault: vault,
+ underlying: _underlying,
+@> OwnerIsManager: currentOwnerOfReceipt == manager
+ });
+```
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+1. If the intended behavior is to use two different `manager` variables (parameter and a local variable), then renaming the second one will avoid confusion.
+2. If this is not the intended behavior, then the logic of the two `manager`s should be revisited.

+
+### Mitigation
+
+To ensure that the lenders will receive the correct amount of collateral after liquidation, consider adding checks in `buyNFT()` validating that the buyer will cover the fee on transfer OR the `Auction` is exempt from tax like `TaxTokenReceipt` is supposed to be. Alternatively if by design lenders should cover this cost, validate the `amount` passed to `handleAuctionSell()` against the loan's underlying token balance.

+# Race Condition at Loan Deadline Creates Temporary DOS
+
+### Summary
+
+The DebitaV3Loan contract contains inconsistent deadline checks between `payDebt` and `claimCollateralAsLender` functions, creating a race condition at the exact deadline timestamp where neither borrower nor lender can interact with the loan.
+
+### Root Cause
+
+In [`payDebt`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L186) function of DebitaV3loan contract:
+```solidity
+require(nextDeadline() >= block.timestamp, "Deadline passed to pay Debt");
+```
+ In [claimCollateralAsLender](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L340) function:
+```solidity
+require(_nextDeadline < block.timestamp && _nextDeadline != 0, "Deadline not passed");
+```
+
+Inconsistent deadline comparison operators
+- `>=` in payDebt prevents payment at exact deadline
+- `<` in claimCollateralAsLender prevents claim at exact deadline
+No clear specification of who should have priority at deadline
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+When block.timestamp == nextDeadline():
+- Borrower's payment reverts because nextDeadline() >= block.timestamp fails
+- Lender's claim reverts because _nextDeadline < block.timestamp fails
+
+Loan enters temporary deadlock:
+- Temporary denial of service at exact deadline timestamp.
+- Neither borrower can repay nor lender can claim collateral
+- Affects core loan functionality at critical moment
+
+### PoC

+
+### Mitigation

+}
+
+function claimCollateralAsLender() {

+# Underflow Risk and Invalid Offset Handling in Retrieval Functions
+
+### Summary
+Three functions (`getActiveBorrowOrders`, `getActiveAuctionOrders`, and `getActiveOrders`) have a similar issue where the code does not validate that the offset is less than the calculated length before attempting an array operation. This omission can lead to an underflow during the calculation of array size (length - offset), resulting in a revert or unintended behavior.
+
+### Code Snippet:
+`DBOFactory`
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L183-L189
+`DLOFactory`
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L226-L233
+`AuctionFactory`
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L121-L129
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L171-L178
+`DebitaV3Aggregator`
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L698-L706
+
+### Affected Functions
+`getActiveBorrowOrders`
+`getActiveAuctionOrders`
+`getActiveOrders`
+`getHistoricalAuctions`
+`getAllLoans`
+
+### Vulnerability Details
+## Issue: Unchecked Offset Value
+All five functions assume that the `offset` provided as input will always be valid relative to the `activeOrdersCount`/`historicalAuctions.length` and `limit`. However, if `offset` exceeds or equals length (determined by the smaller of `limit` or `activeOrdersCount`/`historicalAuctions.length`), the subtraction length - offset results in Zero or an underflow.
+
+## For Example:
+If activeOrdersCount/historicalAuctions.length = 5, limit = 10, and offset = 7, the following occurs:
+length = 5 (since limit > activeOrdersCount/historicalAuctions.length).
+length - offset = 5 - 7, which results in an underflow.
+This reverts the transaction or create unexpected behavior.
+
+Specific Lines of Concern:
+
+`getActiveBorrowOrders`:
+```solidity
+DBOImplementation.BorrowInfo[] memory result = new DBOImplementation.BorrowInfo[](length - offset);
+```
+
+`getActiveAuctionOrders`:
+```solidity
+DutchAuction_veNFT.dutchAuction_INFO[] memory result = new DutchAuction_veNFT.dutchAuction_INFO[](length - offset);
+```
+
+`getActiveOrders`:
+```solidity
+DLOImplementation.LendInfo[] memory result = new DLOImplementation.LendInfo[](length - offset);
+```
+
+`getHistoricalAuctions`
+```solidity
+DutchAuction_veNFT.dutchAuction_INFO[] memory result = new DutchAuction_veNFT.dutchAuction_INFO[](length - offset );
+```
+
+`getAllLoans`
+```solidity
+DebitaV3Loan.LoanData[] memory loans = new DebitaV3Loan.LoanData[](limit - offset);
+```
+
+Potential Impact:
+
+Reverts: The underflow will cause the transaction to fail unnecessarily.
+Invalid Data Handling: Even if a revert does not occur, it will return an empty array.
+
+### Mitigation
+1. Validate the Offset: Add a check to ensure offset is within the valid range before proceeding with any operations. This prevents the underflow and ensures consistent behavior.
+Updated Validation Code:
+
+```solidity
+require(offset < activeOrdersCount, "Offset exceeds total orders");
+```
+
+2. Adjust the Array Length Calculation: Ensure that the array initialization accounts for the offset by using a conditional or calculated length:
+
+```solidity
+uint length = limit;
+if (limit > activeOrdersCount) {
+ length = activeOrdersCount;
+}
+require(offset < length, "Invalid offset"); // Additional check
+uint resultLength = length > offset ? length - offset : 0;
+```

+# The principle in the `claimIncentives` function is not checked against a whitelist
+
+### Summary
+
+In the `claimIncentives` function, we directly use the principle to fetch the lent and borrowed amounts and calculate the incentives However, it's unclear whether this principle is required to be on a whitelist. This lack of verification could potentially allow malicious users to claim rewards for unapproved `principles`.
+
+### Root Cause
+
+Vulnerable code:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L150-L151
+As we can see, the `principle` provided by the user is used directly without any check to verify if it is on the whitelist. This is an oversight.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+- The attacker has lent or borrowed amounts during the corresponding epoch.
+- The principle provided by the attacker is not on the required whitelist.
+
+### Attack Path
+
+The attacker can borrow a large amount of funds and use a `principle` that is not on the whitelist to claim additional rewards.
+
+### Impact
+
+The incentives claiming is unreasonable.
+
+
+### PoC
+
+_No response_
+
+### Mitigation

+# DebitaIncentives::updateFunds Does Not Check All validPairs
+
+### Summary
+
+The `updateFunds` function is called by the aggregator contract to update the user's funds and the total principal amount. However, the function **prematurely returns** before iterating through all `validPairs`, potentially leaving valid updates unprocessed.
+
+### Root Cause
+
+The updateFunds function assumes that the input pairs (lendOrders) are always provided in the correct order. If they are not, the function returns prematurely, failing to update the storage for all valid pairs.
+Relevant code:
+[DebitaIncentives.sol#L317](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L317)
+
+### Internal pre-conditions
+
+1. DBO and DLO avaiable
+
+### External pre-conditions
+
+None
+
+### Attack Path
+
+1. A caller of DebitaV3Aggregator::matchOffersV3 can deliberately structure the lendOrders argument so that the first entry does not correspond to a validPair.
+
+2. This causes updateFunds to return early, denying lenders and borrowers the opportunity to earn additional rewards.
+
+### Impact
+
+* Lenders and borrowers lose the chance to earn additional rewards due to incomplete updates of valid pairs.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Replace the premature return statement with a continue statement to ensure all pairs are checked:
+
+```solidity
+ if (!validPair) {
+ continue;
+ }
+```

+# `TaxTokensReceipt` used as collateral always leads to loss of funds due to custom `transferFrom()` limitations
+
+### Summary
+
+The `TaxTokensReceipt` ERC721 overrides the default `transferFrom()` function to ensure that the NFT can be transferred only between Debita's contracts:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L98-L106
+It fails to cover all possibilities of valid `to` and `from` addresses still inside Debita's ecosystem.
+
+### Root Cause
+
+Custom validation of the `to` and `from` addresses fails to cover the transfer from `Auction` contract to NFT seller, which happens after full or partial liquidation.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L148-L153
+That's the receipt NFT transfer, where `nftAddress` is the `TaxTokensContract` address.
+
+
+### Internal pre-conditions
+
+- loan is created where `TaxTokensReceipt` NFT is used as collateral
+
+
+### External pre-conditions
+
+--
+
+### Attack Path
+
+--
+
+### Impact
+
+Loss of funds for either borrower or lender depending on conditions due to collateral NFT being stuck in an auction.
+
+1. One lend order:
+For this scenario this has an impact when the loan is not repaid and the borrower maliciously initializes an auction making it impossible for the lender to withdraw ERC721 itself. Borrower *can* withdraw the NFT after an honest loan ends.
+
+2. Multiple lend orders:
+In that case the issue will lock both parties unless the loan is repaid in full - because then the borrower can also withdraw the NFT without utilising the auction.
+
+
+### PoC
+
+To create a PoC entire setup for `TaxTokensContract`-based loan that was initially made for a more complex finding was utilized. This helps to simulate the actual transfer failure in practice during the `claimCollateralAsLender()` call rather than PoCing simple transfer to an unsupported address. The code from the dropdown below shows the case with one lend order where the borrower does not repay the loan.

+
+
+### Mitigation
+
+Adding support to `Auction` contract similarly to other Debita's contracts is not an option because a new one is deployed for each liquidation. Consider adding some sort of mapping indicating the transfer is from the `Auction` contract and add a permissioned function to flag the new auction as allowed after deployment in `AuctionFactory`.

+# Wrong Formula to calculate LTV in `DebitaV3Aggregator::matchOffersV3` will Cause Lenders to Lose Money
+
+### Summary
+
+The [`DebitaV3Aggregator::matchOffersV3`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274) is used to match a borrow order with multiple lend orders. If the lend order or borrow order uses oracles to fetch live data, their LTV calculation for the loan will be wrong. This will cause the borrowers to lose money substantially because the LTV formula is flipped from the original formula.
+
+### Root Cause
+
+The [`matchOffersV3`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274) is used to match a borrow offer with multiple lend offers. This is done by calculating the LTV ratio for both borrow and lend offers and ensuring that both parties are happy with their loan.
+
+The `ratio` calculated for both borrow and lend offers in the function is using the wrong formula. For example, for the [borrow offer](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L350):
+
+```solidity
+@> uint ValuePrincipleFullLTVPerCollateral = (priceCollateral_BorrowOrder *
+ 10 ** 8) / pricePrinciple;
+
+uint value = (ValuePrincipleFullLTVPerCollateral *
+ borrowInfo.LTVs[indexForPrinciple_BorrowOrder[i]]) / 10000;
+uint ratio = (value * (10 ** principleDecimals)) / (10 ** 8);
+ ratiosForBorrower[i] = ratio;
+```
+
+For each [lending offer](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L451):
+
+```solidity
+@> uint fullRatioPerLending = (priceCollateral_LendOrder *
+ 10 ** 8) / pricePrinciple;
+uint maxValue = (fullRatioPerLending *
+ lendInfo.maxLTVs[collateralIndex]) / 10000;
+uint principleDecimals = ERC20(principles[principleIndex])
+ .decimals();
+maxRatio = (maxValue * (10 ** principleDecimals)) / (10 ** 8);
+
+...
+
+uint ratio = (maxRatio * porcentageOfRatioPerLendOrder[i]) / 10000;
+```
+
+The reason the above formulas are wrong is proven in the following [line](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L453):
+```solidity
+uint maxValue = (fullRatioPerLending *
+ lendInfo.maxLTVs[collateralIndex]) / 10000;
+```
+
+Let's look at that a little more closely:
+
+$$maxValue = \frac{fullRatioPerLending \times maxLTV}{10000}$$
+
+This function is trying to calculate the maximum allowed value of a loan based on the user set `maxLTV` in the `LendInfo` and similarly the allowed value of a loan based on the user set `LTV` in the `BorrowInfo`.
+
+Presumably, the user will think that the `LTV` calculation formula will be the following based on all sources of definitions: [In traditional accounting](https://www.investopedia.com/terms/l/loantovalue.asp), and [in web3 accounting](https://coinmarketcap.com/academy/glossary/loan-to-value-ltv):
+
+$$LTV = \frac{LoanAmount}{MarketValueOfCollateral}$$
+
+In the current function, the formula needs to be:
+```solidity
+uint ValuePrincipleFullLTVPerCollateral = (pricePrinciple *
+ 10 ** 8) / priceCollateral_BorrowOrder;
+```
+
+### How does this affect the user?
+To answer that question let's understand what the respective formulas are calculating:
+*Original Formula:*
+
+$$maxValue = \frac{priceCollateral}{pricePrinciple} \times maxLTV_{Lender}$$
+
+This function calculates the maximum value of this particular Lend Order, and it is understood as the **maximum price of Collateral per price of Principle**.
+In other words, how much maximum collateral that needs to be present per loan given out.
+For example: a `maxValue` of `0.5` in this case means that for every `$1` in collateral, you can take out `$2` in loan principle.
+In this case `maxValue > 1` is better than `maxValue < 1`
+
+*Corrected Formula:*
+
+$$maxValue = \frac{pricePrinciple}{priceCollateral} \times maxLTV_{Lender}$$
+
+This function will calculate the maximum value of this Lend Order as the **maximum price of the Principle per price of Collateral**.
+In other words, how much maximum loan can you take out per collateral available.
+For example: a `maxValue` of `0.5` in this case means that for every `$1` in loan principle, you will have `$2` in collateral.
+In this case `maxValue < 1` is better than `maxValue > 1`
+
+Both formulas work perfectly if it is implemented consistently across the board. This is not true because the `LendOffer` asks `maxLTVs` per collateral, `BorrowOffer` asks for `LTVs` for each principle-collateral token they would like to accept, but the `matchOffersV3` calculates `VTL` and multiplies it with `LTV`.
+
+So, a user might think they want their loan to have `80:100 = 0.8` `LTV` ratio, in other words for every `$80` in loan, they want `$100` in collateral just to be safe.
+On the other hand, according to the current implementation of the function, the user's `0.8` `LTV` function will get them `$80` collateral, for every `$100` loan.
+
+As you can see, this can be troublesome when loans default and the user gets less collateral back than they set.

+
+### Attack Path
+
+1. An attacker will see a lend order from Alice for `$10,000` with `90%` maxLTV using either Chainlink or Pyth Oracle.
+2. The attacker will create a borrow order for `$10,000` with `90%` LTV.
+3. The attacker will call the `matchOffersV3` function with the borrow and lend offers.
+4. Attacker will receive the `$10,000` from Alice.
+5. Attacker will default on the loan.
+6. Alice will claim the collateral, but instead of getting a collateral valued at `$11,111` like she should have, she will get a collateral valued at `$9,000`.
+7. Attacker gains `$1,000`, Alice loses `$1,000`.
+
+### Impact
+
+The attacker will make the following profit in each lend order they match with:
+
+$$profit = (1 - LTV) \times loanPrinciple$$
+
+So, for a loan of `$10,000`:
+`LTV = 0.8; Profit = $2000`
+`LTV = 0.7; Profit = $3000`
+`LTV = 0.1; Profit = $1000`
+
+A lower LTV rate is considered a safer investment, but with the current setup, **a lower LTV increase the risk substantially**.

+# Confidence interval check missing in Pyth network prices
+
+### Summary
+
+Pyth network shows how confident it is about its prices using something called a confidence range. For each price 'p', there's a number 'σ' that tells us how much that price could go up or down. The Pyth team has written guidelines about using this confidence range to make things safer. For example, you can divide 'σ' by 'p' - if this number is too big, you might want to stop trading until prices are more stable.
+
+At the moment, the protocol isn't paying attention to this confidence range feature at all. It would be a good idea to start using it like Pyth suggests, as this would help stop people from taking advantage when prices aren't accurate. Here are the Pyth docs:
+https://docs.pyth.network/price-feeds/best-practices#confidence-intervals
+
+### Root Cause
+
+Here is the vulnerable function:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L25

+### External pre-conditions

+
+### Attack Path
+
+A user might be able to take advantage of the incorrect price
+
+### Impact
+
+`MixOracle` uses `DebitaPyth` oracle in it's calculations. If the price returned is incorrect that would make all the contracts's calculation that use the `MixOracle` incorrect.
+
+### PoC
+
+No PoC
+
+### Mitigation
+
+Make sure this check is in the DebitaPyth::getThePrice function:
+
+```solidity
+error PriceConfidenceTooLow();
+
+ if ((priceData.price / int64(priceData.conf) < minConfidenceRatio) && priceData.conf > 0 ) {
+ revert PriceConfidenceTooLow();

+# `DebitaV3Loan::claimCollateralAsLender` calls `claimCollateralAsNFTLender` but does not check the returned bool, which could lead to the lender's nft being burned without claiming his collateral part if the borrower has been defaulted
+
+### Summary
+
+In the `DebitaV3Loan` contract the `claimCollateralAsLender` function call the internal function `claimCollateralAsNFTLender`, which returns a bool, but this result is not check, whether is was successful or not. This unchecked return value can be fasle, meaning that the lender did not get any portion of the collateral and his NFT is still burned and `collateralClaimed` is set to true.
+
+### Root Cause
+
+The vulnerability lays in this function call:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L361
+
+### Internal pre-conditions
+
+1. Deadline should have passed, resulting in a default: `_nextDeadline < block.timestamp && _nextDeadline != 0`
+2. The lender should have not claimed his collateral: `offer.collateralClaimed == false`
+3. The collateral of the borrow offer should be an NFT - `m_loan.isCollateralNFT == true`
+4. An auction should not be initialized - `m_loan.auctionInitialized == fasle`
+5. There should be more than one lender in the lend offer; `m_loan._acceptedOffers.length != 1`
+
+There are a lot of pre-conditions, but they are likely to happen
+
+### External pre-conditions
+
+None
+
+### Attack Path
+
+1. A loan is created with more than one lenders and the borrower's collateral is a veNFT
+2. The loan passes the deadline and is defaulted
+3. One of the lenders decides to claim his collateral, but an auction has not been created yet
+4. The lender calls `claimCollateralAsLender`, which burns his NFT that represent ownership then the internal `claimCollateralAsNFTLender` function is called and sets `collateralClaimed = true`. The result from `claimCollateralAsNFTLender` is not checked and the whole `claimCollateralAsLender` function passes. The lender does not get any amount of tokens. This also prevents further calls to actually claim his collateral, when the veNFT is sold, because of this check: `require(offer.collateralClaimed == false, "Already executed");`
+5. Now the lender has no way of claiming his colleral
+
+### Impact
+
+1. No way for the lender to claim his collateral after calling `claimCollateralAsLender` with the mentioned pre-conditions, effectively locking his collateral forever.
+
+### PoC
+
+No PoC
+
+### Mitigation
+
+Make sure to check the returned bool of the `claimCollateralAsNFTLender` funciton call:

+# Loan Extension Fails Due to Unused Time Calculation
+
+### Summary
+
+The `extendLoan` function in `DebitaV3Loan::extendLoan` has redundant time calculation logic that causes transaction reversions when borrowers attempt to extend loans near their deadline.
+
+### Root Cause
+
+In the `DebitaV3Loan` contract the function `extendLoan` function has a varaible `extendedTime` that is not used and can cause reverts in some cases which cause some borrowers to not be able to extend their loan.
+
+The exact line of code:
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L590
+
+### Internal pre-conditions
+
+1. Loan must not be already extended `(extended == false)`
+2. Borrower must have waited minimum duration `(10% of initial duration)`
+3. Loan must not be expired `(nextDeadline() > block.timestamp)`
+4. Must have at least one unpaid offer
+
+### External pre-conditions
+
+1. Current time must be close to offer's `maxDeadline`
+2. `maxDeadline - (block.timestamp - startedAt)` - `block.timestamp` < 0
+
+### Attack Path
+
+1. Loan starts at timestamp `1704067200` (January 1, 2024)
+2. Time advances to `1705190400` (January 14, 2024)
+3. Borrower attempts to extend loan
+4. For an offer with maxDeadline `1705276800` (January 15, 2024)
+5. Transaction reverts due to arithmetic underflow
+
+### Impact
+
+Borrowers cannot extend loans near their deadlines even when they satisfy all other requirements:
+
+1. Forces unnecessary defaults near deadline
+2. Wastes gas on failed extension attempts
+3. Disrupts normal loan management operationsthe
+
+### PoC
+
+This PoC demonstrates the reversion caused by unused time calculations in `extendLoan` function.
+
+```solidity
+contract BugPocTime {
+
+ uint256 loanStartedAt = 1704067200; // 1 January 00:00 time
+ uint256 currentTime = 1705190400; // 14 January 00:00 time
+ uint256 maxDeadline = 1705276800; // 15 January 00:00 time
+
+ function extendLoan() public view returns(uint256){
+ uint256 alreadyUsedTime = currentTime - loanStartedAt;
+ uint256 extendedTime = maxDeadline - alreadyUsedTime - currentTime;
+
+ return 10;
+ }
+}
+```
+
+The example uses the following timestamps:
+
+1. loanStartedAt: 1704067200 (Jan 1, 2024 00:00)
+2. currentTime: 1705190400 (Jan 14, 2024 00:00)
+3. maxDeadline: 1705276800 (Jan 15, 2024 00:00)
+
+The calculation flow:
+
+1. alreadyUsedTime = 1705190400 - 1704067200 = 1,123,200 (≈13 days)
+2. extendedTime = 1705276800 - 1,123,200 - 1705190400
+ = 1705276800 - 1706313600
+ = -1,036,800 (reverts due to underflow)
+
+
+### Mitigation
+
+Remove the unused `extendedTime` calculation as it serves no purpose and can cause legitimate loan extensions to fail.

+
+### Attack Path
+
+1. Owner attempts ownership transfer via `changeOwner`
+2. Permission checks succeed
+3. Variable shadowing causes parameter to update itself
+4. Contract ownership remains with original owner
+5. No error message indicates transfer failure
+
+### Impact
+
+Critical ownership functionality is compromised:
+
+1. Ownership cannot be transferred during crucial initial period
+2. First owner becomes permanent by default
+3. Emergency ownership transfers blocked during setup phase
+
+### PoC
+
+I made a basic contract with exactly the same owner functionality to demonstrate the bug:
+
+```javascript
+// SPDX-License-Identifier: MIT
+pragma solidity 0.8.0;
+
+contract TestOwnerOverwrite {
+ address owner;
+
+ uint256 deployedTime;
+
+ constructor() {
+ owner = msg.sender;
+ deployedTime = block.timestamp;
+ }
+
+ function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+
+ function getOwner() public view returns (address) {
+ return owner;
+ }
+}
+```
+
+Here is the test to see the bug:
+
+```javascript
+// SPDX-License-Identifier: MIT
+pragma solidity 0.8.0;
+
+import {console, Test} from "forge-std/Test.sol";
+import {TestOwnerOverwrite} from "./Owner.sol";
+
+contract OwnerTest is Test {
+ TestOwnerOverwrite ownerContract;
+ address owner = makeAddr("owner");
+ address newOwner = makeAddr("newOwner");
+
+ function setUp() public {
+ vm.prank(owner);
+ ownerContract = new TestOwnerOverwrite();
+ }
+
+ function testOwershipTransferDoesNotSucced() public {
+ assert(ownerContract.getOwner() == owner);
+
+ vm.prank(owner);
+ vm.expectRevert();
+ ownerContract.changeOwner(newOwner);
+
+ address newExpectedOwner = ownerContract.getOwner();
+ assert(newExpectedOwner != newOwner);
+ }
+}
+```
+
+### Mitigation
+
+Resolve naming conflict by using distinct parameter name:
+
+```solidity
+function changeOwner(address newAddress) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = newAddress;
+ }
+```

+# Borrowers Bear the 15% Protocol Fee While Lenders Are Exempted
+
+### Summary
+
+The [documentation](https://debita-finance.gitbook.io/debita-v3/overview/fees#loans) stated the following:
+> Lender will pay 15% on the interest paid by the borrower.
+
+It is implemented incorrectly where borrower pays the 15% instead.
+
+### Root Cause
+
+The `DebitaV3Loan::payDebt` function is used to repay the loan along with interest. The additional 15% fee was charged to `msg.sender` (the borrower) rather than the lender contract. As a result, the 15% fee is applied each time a debt is repaid, with the lenders remaining unaffected by the charge.
+
+```solidity
+ function payDebt(uint[] memory indexes) public nonReentrant {
+ -- SNIP --
+ uint interest = calculateInterestToPay(index);
+ uint feeOnInterest = (interest * feeLender) / 10000;
+ uint total = offer.principleAmount + interest - feeOnInterest;
+ address currentOwnerOfOffer;
+
+ try ownershipContract.ownerOf(offer.lenderID) returns (
+ address _lenderOwner
+ ) {
+ currentOwnerOfOffer = _lenderOwner;
+ } catch {}
+
+ DLOImplementation lendOffer = DLOImplementation(offer.lendOffer);

+### Mitigation
+
+It is possible that the lender's contract does not have the tokens to pay the debt. Hence, remove the following snippet within the `DebitaV3Loan::payDebt()` and ``DebitaV3Loan::extendLoan()`, and include the fee payment logic to feeAddress within `DebitaV3Loan::claimDebt`.

+# Array Out of Bounds in `getHistoricalBuyOrders` of buyOrderFactory` contract Causes DOS
+
+### Summary
+
+The `getHistoricalBuyOrders` function in `buyOrderFactory` contract contains two critical array-related errors:
+- Incorrect array size calculation using wrong variable ("limit - offset")
+- Array `index out-of-bounds` error in loop iteration. ("i < offset + limit")
+This can cause denial of service for Historical Buy order retrieval functionality in most cases.
+
+### Root Cause
+
+In BuyOrderfactory contract [getHistoricalBuyOrders](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L159) function,
+
+```solidity
+function getHistoricalBuyOrders(
+ uint offset,
+ uint limit
+ ) public view returns (BuyOrder.BuyInfo[] memory) {
+ uint length = limit;
+
+ if (limit > historicalBuyOrders.length) {
+ length = historicalBuyOrders.length;
+ }
+
+ BuyOrder.BuyInfo[] memory _historicalBuyOrders = new BuyOrder.BuyInfo[](
+ @--> limit - offset. //@audit has to be length- offset
+ );
+ @--> for (uint i = offset; i < offset + limit; i++) {
+ address order = historicalBuyOrders[i];
+ _historicalBuyOrders[i] = BuyOrder(order).getBuyInfo();
+ }
+ return _historicalBuyOrders;
+ }
+
+```
+Error 1: Array Size Calculation:
+- Uses `limit - offset` instead of `length - offset`
+- limit could be larger than historicalBuyOrders.length
+- Creates array larger than available items

+# `DebitaV3Aggregator::getPriceFrom()` does not account for the decimals returned by `chainlink`, an attacker can use this to drain all lender principle
+
+### Summary
+
+Different `chainlink` price feeds can return values with different decimals, even though the base currency is the same. For example on `Arbitrum` : [PEPE/USD](https://arbiscan.io/address/0x02DEd5a7EDDA750E3Eb240b54437a54d57b74dBE#readContract) (18 dec) and [USDC/USD](https://arbiscan.io/address/0x50834F3163758fcC1Df9973b6e91f0F0F0434aD3#readContract) (8 dec).
+
+The main problem is that `getPriceFrom()` assumes that the returned amount is denominated in the same number of decimals for all tokens.
+
+### Root Cause
+
+*[DebitaV3Aggregator.sol:721 - 727](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L721-L727) assumes that the returned amount is denominated in the same number of decimals for all tokens, it can be 8 or 18*
+
+### Internal pre-conditions
+
+Borrower and lender must have the same accepted principle and accepted collateral (e.g `PEPE` and `USDC`)
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+Borrower use PEPE as collateral and lender use USDC as principle
+
+Borrower create a BorrowerOffer :
+
+```solidity
+bool[] memory _oraclesActivated : _oraclesActivated[0] = true
+uint[] memory _LTVs : _LTVs[0] = 0
+uint _maxInterestRate : _maxInterestRate = 1000
+uint _duration : _duration = 864000
+address[] memory _acceptedPrinciples : _acceptedPrinciples[0] = USDC (6 decimal)
+address _collateral : _collateral = PEPE (18 decimal)
+bool _isNFT : _isNFT = false
+uint _receiptID : _receiptID = 0
+address[] memory _oracleIDS_Principles : _oracleIDS_Principles[0] = address oracle of USDC
+uint[] memory _ratio : _ratio[0] = 1e6
+address _oracleID_Collateral : _oracleID_Collateral = address oracle of PEPE
+uint _collateralAmount : _collateralAmount = 10e18
+
+```
+
+Lender create a LendOffer :
+
+```solidity
+bool _perpetual : _perpetual = false
+bool[] memory _oraclesActivated : _oraclesActivated[0] = true
+bool _lonelyLender : _lonelyLender = true
+uint[] memory _LTVs : _LTVs[0] = 10000
+uint _apr : _apr = 1000
+uint _maxDuration : _maxDuration = 8640000
+uint _minDuration : _minDuration = 86400
+address[] memory _acceptedCollaterals : _acceptedCollaterals[0] = PEPE (18 decimal)
+address _principle : _principle = USDC (6 decimal)
+address[] memory _oracles_Collateral : _oracles_Collteral[0] = address oracle of PEPE
+uint[] memory _ratio : _ratio[0] = 1e6
+address _oracleID_Principle : _oracleID_Principle = address oracle of USDC
+uint _startedLendingAmount : _startedLendingAmount = 10e6
+
+```
+
+And aggreator match the both offer :
+
+```solidity
+address[] memory lendOrders : lendOrders[0] = address of lend order
+uint[] memory lendAmountPerOrder : lendAmountPerOrder[0] = 2e6
+uint[] memory porcentageOfRatioPerLendOrder : porcentageOfRatioPerLendOrder[0] = 10000
+address borrowOrder : borrowOrder = address of borrow order
+address[] memory principles : principles[0] = USDC (6 decimal)
+uint[] memory indexForPrinciple_BorrowOrder : indexForPrinciple_BorrowOrder[0] = 0
+uint[] memory indexForCollateral_LendOrder : indexForCollateral_LendOrder[0] = 0
+uint[] memory indexPrinciple_LendOrder : indexPrinciple_LendOrder[0] = 0
+
+```
+
+Then the calculation will be :
+
+```solidity
+Assume 1 PEPE = 1 USDC = 1 USD
+
+Borrower part

+
+pricePrinciple = 1e8
+
+fullRatioPerLending
+= (priceCollateral_LendOrder *
+ 10 ** 8) / pricePrinciple;
+= (1e18 * 1e8) / 1e8
+= 10_000_000_000e8 == 1e18
+
+maxValue
+= (fullRatioPerLending *
+lendInfo.maxLTVs[collateralIndex]) / 10000;
+= (10_000_000_000e8* 10000) / 10000
+= 1e18
+
+principleDecimals = 1e6
+
+lendAmountPerOrder = 2e6
+
+maxRatio
+= (maxValue * (10 ** principleDecimals)) / (10 ** 8)
+= (1e18 * 1e6) / 1e8
+= 100_000_000e8
+
+ratio
+= (maxRatio * porcentageOfRatioPerLendOrder[i]) / 10000;
+= (100_000_000e8 * 10000 ) / 10000;
+= 100_000_000e8
+
+userUsedCollateral
+= (lendAmountPerOrder[i] *
+ (10 ** decimalsCollateral)) / ratio;
+= (2e6 * 1e18) / 100_000_000e8
+= 2_000_000e18 / 100_000_000e8
+= 200e8 == 0.00000002e18
+
+```
+
+So borrower only need 0.00000002 PEPE to borrow 2 USDC, what should happen is the borrower needs 2 PEPE for 2 USDC
+
+### Impact
+
+Borrower can drain all lender assets with very little amount of collateral
+
+### PoC
+
+See attack path above
+
+### Mitigation
+
+In the `getPriceFrom()` function check how many decimals the returned value has and then normalize them to the same value

+# Missing validation for stale prices on multiple price feeds in `DebitaChainlink.sol`.
+
+### Summary
+
+The Debita V3 contracts are vulnerable to insufficiently filled interest and etc. due to missing price staleness check.
+
+Chainlink price feeds usually update the price of an asset once it deviates a certain percentage. For example the
+ETH/USD price feed updates on 0.5% change of price. If there is no change for 1 hour,
+the price feed updates again - this is called heartbeat.
+
+For example ETH/USD price feed updates on 1 hour heartbeat on Etherium mainnet, other chains have different
+heartbeat intervals.
+
+For example:
+[ARBITRUM - ETH/USD](https://data.chain.link/feeds/arbitrum/mainnet/eth-usd)
+[BASE - ETH/USD](https://data.chain.link/feeds/base/base/eth-usd)
+Here we can see a difference in heartbeat intervals of
+0.10% deviation threshold and more than 23 hours on interval.

+# NFT sellers can be tricked into selling for very little or no collateral with tiny `buyRatio` in `buyOrder`
+
+### Summary
+
+Buy orders can be created with an arbitrarily small positive buy ratio. Unfortunate NFT sellers could verify the ratio to be `1` and call `sellNFT` not thinking that it should have decimals.
+
+### Root Cause
+
+No lower limit or "slippage" protection for the `sellNFT()` selling price together with allowing arbitrarily small `buyRatio`:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L111-L116
+Until the `amount` is less than `availableAmount` and `availableAmount` is not 0, the function will execute.
+
+
+### Internal pre-conditions
+
+- NFT seller makes a wrong assumption about `buyRatio` having no decimals when choosing a limit order to sell their NFT
+
+### External pre-conditions
+
+--
+
+### Attack Path
+
+Malicious buyer deliberately creates a limit order with a ratio set to `1`.
+
+
+### Impact
+
+The likelihood of a seller's mistake is quite low, but the impact if that happens is very high as the seller loses their NFT with all underlying tokens regardless of their total value.
+
+
+### PoC
+
+Add the following test case to `BuyOrder.t.sol` test file:
+```solidity
+ function test_NFTSellerCanGetItAlmostForFree() public {
+ address maliciousBuyer = makeAddr("malicious buyer");
+
+ vm.startPrank(maliciousBuyer);
+ deal(AERO, maliciousBuyer, 100e18);
+
+ AEROContract.approve(address(factory), 100e18);
+ address _buyOrderAddress = factory.createBuyOrder(
+ AERO,
+ address(receiptContract),
+ 100e18,
+ 1
+ );
+ buyOrderContract = BuyOrder(_buyOrderAddress);
+
+ vm.stopPrank();
+
+ vm.startPrank(seller);
+ receiptContract.approve(address(buyOrderContract), receiptID);
+ buyOrderContract.sellNFT(receiptID);
+ vm.stopPrank();
+
+ // seller received just 100 "wei" of AERO.
+ assertEq(AEROContract.balanceOf(seller), 100);
+
+ }
+```
+Run it with:
+```shell
+ forge test --fork-url https://mainnet.base.org --fork-block-number 21151256 --mt test_NFTSellerCanGetItAlmostForFree -vvvvv
+```
+
+As expected the tx executes successfully, leaving the seller with almost nothing.
+
+### Mitigation
+
+Add a `minAmount` parameter to `sellNFT()` function to protect the seller from malicious buyers.

+# Missing vault related states update when burning receipt with VeNFTAerodrome::burnReceipt method.
+
+### Summary
+
+Vault related states are not updated when veNFTAerodrome::burnReceipt method is called as the owner withdrawing her NFT .
+
+### Root Cause
+
+NFT receipt holder can withdraw NFT from vault via withdraw() method in veNFTVault. Inside the withdraw function, the holder needs to burn NFT receipt to get her NFT back. However when burning receipt ID, the vault related data is not updated, such as "s_ReceiptID_to_Vault[m_Receipt]"(=address(0)) and "isVaultValid[address(vault)]"(=false). This will leave the vault manager to be able to call calimBribes/reset/extend/poke functions even after the NFT been withdrawed from vault.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/veNFTS/Aerodrome/Receipt-veNFT.sol#L309-L311

+# Pyth oracle not validating confidence ratio
+
+### Summary
+
+Debita Pyth oracle can return stale prices do to the improper validation, which can result in attackers or users taking advantage of invalid prices.
+
+### Vulnerability Details
+
+Considering a provided price `p`, its confidence interval `σ` is roughly the standard deviation of the price's probability distribution.
+The official documentation of [best practices](https://docs.pyth.network/price-feeds/best-practices#confidence-intervals) of the Pyth Price Feeds recommends some ways in which this confidence interval can be utilized for enhanced security. For example, the protocol can compute the value `σ / p` to decide the level of the price's uncertainty and disallow user interaction with the system in case this value exceeds some threshold.
+
+Values of differents price feeds can be looked at [Pyth Price-Feeds](https://pyth.network/price-feeds) page.
+
+Example for [ETH/USD](https://www.pyth.network/price-feeds/crypto-eth-usd) at the time of writing this report:
+
+```solidity
+// Normal Market Condition (Current ETH price)
+price = 347445000000 // $3,474.45 with -8 expo
+expo = -8
+conf = 300500000 // $3.005 with same expo (0.086% uncertainty)
+
+priceMultiplier = 10^8
+actualPrice = 347445000000 * 10^8 = 347445_0000000000000000
+actualConf = 300500000 * 10^8 = 30050_0000000000000
+confidenceRatio = actualPrice / actualConf = 1156 // Very healthy market
+
+// Extreme Market Condition
+price = 347445000000 // Still $3,474.45 but during high volatility
+expo = -8
+conf = 34744500000 // $347.445 with same expo (10% uncertainty)
+
+actualPrice = 347445000000 * 10^8 = 347445_0000000000000000
+actualConf = 34744500000 * 10^8 = 3474450_0000000000000
+confidenceRatio actualPrice / actualConf = 10 // Very low confidence
+```
+
+### Impact
+
+Without confidence interval contract can accept untrusted prices. Leading to attackers or users using untrusted prices in their advantage.
+
+### Tool Used
+
+Manual Review
+
+### Lines of Concern
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L25-L41
+
+### Recommendation
+
+Currently, the protocol completely ignores the confidence interval provided by the price feed. Consider utilizing the confidence interval provided by the Pyth price feed as recommended in the official documentation. This would help mitigate the possibility of attackers or users taking advantage of invalid prices:
+
+```solidity
+ function getThePrice(address tokenAddress) public view returns (int) {
+ // falta hacer un chequeo para las l2
+ bytes32 _priceFeed = priceIdPerToken[tokenAddress];
+ require(_priceFeed != bytes32(0), "Price feed not set");
+ require(!isPaused, "Contract is paused");
+
+ // Get the price from the pyth contract, no older than 90 seconds
+ PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ _priceFeed,
+ 600
+ );
+
+ // Check if the price feed is available and the price is valid
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+ require(priceData.price > 0, "Invalid price");
+
++ uint256 confidenceRatio = uint256(priceData.price) / priceData.conf;
++ require(confidenceRatio >= MIN_CONFIDENCE_RATIO, "Price confidence is too low");
+
+ return priceData.price;
+ }
+```
+
+Where:
+
+`MIN_CONFIDENCE_RATIO` should be a trusted minimum value for the protocol.

+# For loop can be optimized
+
+### Summary
+
+The `getActiveAuctionOrders` function contains redundant calculations within its loop, which can be improved for efficiency and gas optimization. the current implementation calculates `offset + i` in every iteration of the loop to access elements from the `allActiveAuctionOrders` array. This operation introduces unnecessary overhead. By modifying the loop structure and indexing logic, we can eliminate these redundant calculations, making the function more optimized and easier to understand.

+# External calls without failure checks in acceptBorrowOffer function
+
+### Summary
+
+The acceptBorrowOffer function does not verify the success of external calls during collateral transfers. This could leave the contract in an inconsistent state if a transfer fails, potentially resulting in locked collateral or incorrect accounting.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L151
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L157
+
+
+
+### Root Cause
+
+The function modifies the borrowInformation.availableAmount state before executing external calls (IERC721.transferFrom or SafeERC20.safeTransfer) without validating their success. If these calls fail due to issues such as insufficient balance, approval errors, or paused tokens, the contract state will remain inconsistent.
+
+### Internal pre-conditions
+
+1) borrowInformation.availableAmount is modified prior to the external calls.
+2) No success check (require) is performed after the transfer operation.
+
+### External pre-conditions
+
+The transfer operation may fail due to:
+- Insufficient token balance.
+- Lack of approval for ERC-20/ERC-721 tokens.
+- Token contract being paused or restricted.
+
+### Attack Path
+
+1) A borrower initiates a transfer with insufficient token balance or approval.
+2) The external call fails silently.
+3) The borrowInformation.availableAmount and other state variables are already updated, leading to:
+- Discrepancies in available collateral.
+- Invalid assumptions for further transactions (e.g., over-transferring collateral).
+
+### Impact
+
+- Inconsistent Contract State: State variables reflect an incorrect state if transfers fail.
+- Locked Collateral: Collateral may remain inaccessible, disrupting the contract's operation.
+
+### Mitigation
+
+Add Success Checks: Validate external calls to ensure transfers succeed. For example:
+bool success = IERC721(m_borrowInformation.collateral).transferFrom(
+ address(this), aggregatorContract, m_borrowInformation.receiptID
+);
+require(success, "Transfer failed");
+
+Similarly, validate ERC-20 transfers by using require.

+# Lack of Exponent Handling for Fixed-Point Price Representation in Pyth Oracle
+
+## Summary
+
+The `getThePrice()` function does not properly account for the fixed-point exponent used in the price feed data from the Pyth network. As a result, the price retrieved may be incorrectly scaled unless the exponent is handled explicitly.
+
+## Vulnerability Detail
+
+The Pyth network provides price data in a fixed-point format, where the price and its confidence interval are both scaled by an exponent. According to the Pyth documentation, the price is represented as an integer multiplied by 10^exponent. This means that to correctly interpret the price, it must be scaled by 10^-exponent.
+
+ In the `DebitaPyth.sol`, the function [getThePrice()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L25-L41) retrieves the price from the Pyth network through the `pyth.getPriceNoOlderThan()` function. However, the price returned by `getPriceNoOlderThan()` is not adjusted by the `exponent`, which may lead to incorrect price values being returned.
+
+ ```js
+ function getThePrice(address tokenAddress) public view returns (int) {
+ // falta hacer un chequeo para las l2
+ bytes32 _priceFeed = priceIdPerToken[tokenAddress];
+ require(_priceFeed != bytes32(0), "Price feed not set");
+ require(!isPaused, "Contract is paused");
+
+ // Get the price from the pyth contract, no older than 90 seconds
+@> PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ _priceFeed,
+ 600
+ );
+
+ // Check if the price feed is available and the price is valid
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+ require(priceData.price > 0, "Invalid price");
+@> return priceData.price;
+ }
+ ```
+ The issue arises because `priceData.price` is returned without being adjusted by the `exponent`. According to the [Pyth fixed-point representation](https://docs.pyth.network/price-feeds/best-practices#fixed-point-numeric-representation), if the exponent is negative (e.g., -5), the price value must be divided by 10^5 (or 100,000) to correctly interpret the price.
+
+ For example, if the `priceData.price` is 12276250 and the exponent is -5, the correct price should be 122.7625.
+
+ Without applying this exponent adjustment, the contract would return 12276250, which is an incorrect value in terms of USD.
+
+## Impact
+
+Wrong prices end up getting used from pyth oracle.
+
+ ## Recommendation
+```js
+// ensure exponent is handled correctly
+ return priceData.price * (10 ** uint256(-priceData.exponent));
+```

+# Auction Manipulation Risk: Liquidated Borrowers Potentially Reclaiming Collateral and Evading Debt Repayment
+
+### Summary
+
+The missing check of preventing liquidated borrowers from participating in their own liquidation auction in ['auction.buyNFT()'](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109-L184) can lead to them buying back their own collateral at a discounted price. This allows the borrower to evade full debt repayment, regain control of their asset without fully satisfying their debt obligations, or at a price lower than the original debt.
+
+### Root Cause
+
+In `auction.sol:109-184` there's no check on ensuring a liquidated borrower does not participate in their own liquidation auction.
+The protocol ensures that in a liquidation auction, the funds from the sale are used to settle the borrower's debt, and the collateral (NFT) is transferred to the buyer.
+```solidity
+ // If it's a liquidation, handle it properly
+ if (m_currentAuction.isLiquidation) {
+ debitaLoan(s_ownerOfAuction).handleAuctionSell(
+ currentPrice - feeAmount
+ );
+ }
+ IERC721 Token = IERC721(s_CurrentAuction.nftAddress);
+ Token.safeTransferFrom(
+ address(this),
+ msg.sender,
+ s_CurrentAuction.nftCollateralID
+ );
+```
+However it does not include a check to prevent a liquidated borrower from participating in their own liquidation auction.

+### Attack Path
+
+1. Borrower takes a loan of 100 USDC against an NFT valued at 150 USDC at the time of the loan.
+2. The value of the NFT drops due to market conditions, falling to 120 USDC, triggering a liquidation.
+3. The protocol sets up an auction where the starting price is 110 USDC (loan + liquidation fees).
+4. The borrower sees the NFT collateral being auctioned at 110 USDC.
+5. The borrower knows the NFT's value will likely rise when the market recovers and wants to repurchase it.
+6. The borrower bids 110 USDC (the minimum price) reacquiring the NFT.
+7. The borrower regains the NFT for 110 USDC, which is below the current market value of 120 USDC or the potential future value (let’s say it’s worth 150 USDC after market recovery).
+8. The protocol only recovers 110 USDC, which is less than the full loan value, meaning it doesn’t cover the full 100 USDC loan + liquidation fees.
+9. The protocol loses at least 20 USDC (the difference between the auction price and a higher potential recovery value)
+
+### Impact
+
+If this practice is widespread and borrowers can continue to manipulate the system, the protocol could face insolvency issues
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Liquidated borrowers should be restricted from participating in the auction to prevent them from reclaiming their collateral at a discounted price.

+# claimDebt() transfers interest twice to lenders
+
+### Summary
+
+claimDebt() transfers interest twice to lenders
+
+### Root Cause
+
+In [_claimDebt()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L301C1-L309C1), only principal should transfer but it transfers principal as well as interest and sets interest = 0 in memory. However, [claimInterest()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L259C1-L270C1) also transfers interest to the lender, making twice interest transfer to the lender
+```solidity

+ LoanData memory m_loan = loanData;
+ IOwnerships ownershipContract = IOwnerships(s_OwnershipContract);
+
+ infoOfOffers memory offer = m_loan._acceptedOffers[index];

+# External transfer calls without success checks in cancelOffer function
+
+### Summary
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L200
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L207
+
+The cancelOffer function does not validate the success of external calls when transferring collateral back to the owner. This oversight could result in the loss of collateral or an inconsistent contract state if a transfer fails.
+
+### Root Cause
+
+The function executes external calls (IERC721.transferFrom or SafeERC20.safeTransfer) without verifying their success. State variables like borrowInformation.availableAmount and isActive are updated regardless of whether the transfer succeeds.
+
+### Internal pre-conditions
+
+State variables (borrowInformation.availableAmount and isActive) are modified before confirming the success of the collateral transfer.
+The function lacks checks to validate whether IERC721.transferFrom or SafeERC20.safeTransfer succeeds.
+
+### External pre-conditions
+
+External transfer may fail due to:
+- Insufficient balance or approval for ERC-20/ERC-721 tokens.
+- Token contract-level restrictions (e.g., transfer paused).
+- Malfunctions in the underlying token contracts.
+
+### Attack Path
+
+1) A user invokes cancelOffer.
+2) The contract attempts to transfer the collateral back to the owner.
+3) The transfer call fails silently, leaving the collateral stuck in the contract.
+4) State variables (borrowInformation.availableAmount set to 0) incorrectly reflect that the collateral has been successfully transferred, preventing recovery attempts.
+
+### Impact
+
+- Loss of Collateral: Owners may permanently lose access to collateral if the transfer fails.
+- State Inconsistency: Contract state reflects the successful transfer of collateral even when it has failed, disrupting subsequent operations.
+
+### Mitigation
+
+Validate External Call Success: Add explicit checks to confirm the success of the transfer. For example:
+bool success = SafeERC20.safeTransfer(
+ IERC20(m_borrowInformation.collateral), msg.sender, availableAmount
+);
+require(success, "ERC-20 transfer failed");
+
+Similarly for the NFT external transfer call.

+# Listing actives borrow orders while a user has just deleted one (or multiple) borrow order will revert in DebitaBorrowOffer-Factory.sol::getActiveBorrowOrders()
+
+### Summary
+
+The listing of active borrow orders may fail when one or more users delete their borrow orders at the same time.
+
+### Root Cause
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L179
+In `getActiveBorrowOrders()`there is a loop to gather all the active borrow orders desired by the user.
+However, if one or more users deletes one or more borrowOrders while this loop is running, the length of `allActiveBorrowOrders` decreases.
+The loop will continue and reach an index that no longer exists in `allActiveBorrowOrders`.
+The function will revert, giving the error “Index out of bounds”.
+
+### Internal pre-conditions
+
+1. `AllActiveBorrowOrders` contains multiples borrowOrders
+
+### Attack Path
+
+1. a)User1 tries to list some actives BorrowOrders using `getActiveBorrowOrders()`
+ a)User2 deletes his borrowOffer using `deleteBorrowOrders()` `(getActiveBorrowOrders()` is still running)
+2. The loops in `getActiveBorrowOrders()`continues and reach the index just deleted
+3. The function reverts with the error "Index out of bounds"
+
+### Impact
+
+Revert of the function `getActiveBorrowOrders()`
+
+### Mitigation
+
+At the start of the function, copy `allActiveBorrowOrders` into an in-memory array. Changes made to the original array will not affect the in-memory array at runtime.
+```solidity
+function getActiveBorrowOrders(uint offset, uint limit) external view returns (DBOImplementation.BorrowInfo[] memory) {
+ address[] memory activeOrdersSnapshot = allActiveBorrowOrders; // Copie en mémoire
+
+ uint length = limit;

+### Summary
+
+ BorrowOrder can't be created for NFT with `tokenID = 0` due to strict check in `createBorrowOrder()`
+
+### Root Cause

+In [createBorrowOrder()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L90), there is a require statement which checks tokenID/_receiptID not to be 0(zero)

+# Lack of input validations in updateBorrowOrder function
+
+### Summary
+
+The updateBorrowOrder function allows updates to critical parameters (newMaxApr, newDuration, newLTVs, newRatios) without input validation. This could result in undesirable configurations, functional disruptions, or financial risks.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L245
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L246
+
+### Root Cause
+
+Critical parameters can be updated without constraints or validation. For example:
+- newMaxApr can be set to zero.
+- newDuration can take unreasonable values.
+- newLTVs and newRatios are neither checked for length consistency nor for valid ranges.
+
+### Internal pre-conditions
+
+The function directly assigns new values to state variables (maxApr, duration, LTVs, and ratio) without validation.
+No checks are enforced to ensure consistency or reasonable values for the parameters.
+
+### External pre-conditions
+
+1) The function is callable by the contract owner, who may misconfigure parameters due to user error or malicious intent.
+2) Critical dependencies downstream in the system rely on these parameters being valid (e.g., LTV affecting liquidation logic).
+
+### Attack Path
+
+A malicious or careless owner calls updateBorrowOrder with:
+1) newMaxApr = 0, making the borrow order unattractive.
+2) An excessively short newDuration, disrupting loan functionality.
+3) newLTVs and newRatios with unreasonable or mismatched values, breaking internal logic.
+This leads to dysfunctional or harmful updates to the borrow order.
+
+### Impact
+
+- Functional Disruption: Invalid parameter updates (e.g., duration = 0) can make the borrow order unusable.
+
+- Financial Risk: Improper LTVs or ratios could lead to incorrect loan conditions, harming users or the system's financial stability.
+- Trust Loss: Unchecked parameters may reduce user confidence in the platform's integrity
+
+### Mitigation
+
+Validate the input parameters newMaxApr, newDuration, newLTVs and newRatios to be within reasonable values that match
+the protocol's goals. For example:
+require(newDuration > 0 && newDuration <= MAX_DURATION, "Invalid duration");
+require(newMaxApr > 0 && newMaxApr <= MAX_APR, "Invalid APR");

+# Inconsistent Arrays validation and missing 'isActive' check in 'updateBorrowOrder'
+
+## Summary
+The missing active status check and inconsistent array validation in `updateBorrowOrder` will cause potential manipulation of inactive orders and data corruption for borrowers .
+
+## Root Cause
+In [DebitaBorrowOffer-Implementation.sol:232-252](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L232-L253) there are two critical issues:
+
+- The missing active status check before allowing order updates, as the function does not verify the activeness of the borrow order before allowing updates
+
+- The inconsistent array length validation between creation and update flows. When creating a borrow order, the lengths of _LTVs and _ratios are validated to ensure they match the length of _acceptedPrinciples. However, in the updateBorrowOrder function, the validation checks if newRatios.length matches newLTVs.length instead of ensuring it aligns with the length of acceptedPrinciples.
+
+
+## Impact
+- The borrowers suffer potential manipulation of their inactive orders and data corruption.
+- This Inconsistency leads to incomplete data and runtime errors.
+
+## Mitigation
+- Add active status check:
+
+```solidity
+require(isActive, "Offer is not active");
+```
+
+- Add consistent array length validation:
+```solidity
+require(
+ newLTVs.length == borrowInformation.acceptedPrinciples.length,
+ "Invalid LTVs length"
+);
+require(
+ newRatios.length == borrowInformation.acceptedPrinciples.length,
+ "Invalid ratios length"
+);

+# Malicious actor can match his own lend and borrow order using a flash loan to inflate incentives at end of epoch.
+
+### Summary
+
+The [`DebitaV3Aggregator::matchOffersV3`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274) is used to match a borrow order with lend offer.
+The protocol uses `DebitaIncentives.sol` to manage incentives provided for each epoch for borrowers and lenders, which is updated at the end of `matchOffersV3`.
+```solidity
+function matchOffersV3(
+ address[] memory lendOrders,
+ uint[] memory lendAmountPerOrder,
+ uint[] memory porcentageOfRatioPerLendOrder,
+ address borrowOrder,
+ address[] memory principles,
+ uint[] memory indexForPrinciple_BorrowOrder,
+ uint[] memory indexForCollateral_LendOrder,
+ uint[] memory indexPrinciple_LendOrder
+ ) external nonReentrant returns (address) {
+ // . . . . Rest of the Code . . . .
+ // update incentives
+ DebitaIncentives(s_Incentives).updateFunds(
+ offers,
+ borrowInfo.collateral,
+ lenders,
+ borrowInfo.owner
+ );
+ // . . . . Rest of the Code . . . .
+```
+
+The [`DebitaIncentives::updateFunds`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L306) is used in order to update the mappings per epoch.
+```solidity
+function updateFunds(
+ infoOfOffers[] memory informationOffers,
+ address collateral,
+ address[] memory lenders,
+ address borrower
+ ) public onlyAggregator {
+ for (uint i = 0; i < lenders.length; i++) {
+ // . . . . Rest of the Code . . . .
+ lentAmountPerUserPerEpoch[lenders[i]][
+ hashVariables(principle, _currentEpoch)
+ ] += informationOffers[i].principleAmount; <@ - // Updates the borrowAmount per lender
+ totalUsedTokenPerEpoch[principle][
+ _currentEpoch.
+ ] += informationOffers[i].principleAmount;
+ borrowAmountPerEpoch[borrower][
+ hashVariables(principle, _currentEpoch)
+ ] += informationOffers[i].principleAmount; <@ - // Updates the borrowAmount per borrower
+
+ emit UpdatedFunds(
+ lenders[i],
+ principle,
+ collateral,
+ borrower,
+ _currentEpoch
+ );
+ }
+ }
+```
+Which allows users to claim rewards via the [`DebitaIncentives::claimIncentives`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L142) function.
+The issue is with the way incentives are distributed via `updateFunds`, the attacker will wait for incentives to pour in for the majority of the time of an epoch and at the very end of the epoch, he can get serious advantage by creating a lend order and borrow order for himself, matching it to himself using `matchOffesrV3` and at the end pay debt (which is allowed by taking advantage of cross contract re-entrancy attack), all of this by simply using a flash loan.
+As soon as the next epoch starts, attacker will claim his rewards via `claimIncentives`, denying others from majority share of the rewards.
+
+
+
+### Root Cause
+
+The [`DebitaV3Aggregator.sol:274`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274) and [`DebitaV3Loan.sol:186`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L186C14-L186C21) allows a flash loan + cross-contract re-entrancy attack to claim majority rewards of the incentives.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+1. Attacker must be at the end of an epoch whose rewards have been incentivized.
+
+
+### Attack Path
+
+1. On the very last moment of epoch ending, attacker will create a borrow order and a lend order for himself, match the offer using `matchOffersV3` using a flash loan of a high amount.
+2. Attacker will pay debt immediately in the same transaction.
+3. As soon as next epoch starts, he will simply claim majority of the rewards.
+
+### Impact
+
+1. Protocol users will be robbed of most of their share of rewards.
+2. Attacker will gain double rewards for both lender and borrower in this case, basically gaming the system.

+# Potential out-of-Bound access error
+
+### Summary
+
+The loop in the `getHistoricalBuyOrder` function is iterating up to offset+limit, when the _historicalBuyOrders is of length is `limit-offset`, it may lead to a potential issue.
+Similar behaviour is also found in `getActiveBuyOrders` of buyOrderFactory.sol
+
+### Root Cause
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L139-L177
+
+The functions getActiveBuyOrders and getHistoricalBuyOrders exhibit two critical issues in their implementation:
+
+**Mismatched array lengths and iteration ranges.**
+
+- The arrays _historicalBuyOrders and _activeBuyOrders are initialized with a length of limit - offset.
+- However, the for loop iterates from offset to offset + limit, effectively requiring an array length of limit, not limit - offset
+
+**Incorrect indexing during the population of the arrays, leading to potential empty slots.**
+
+- Within the loop, the assignment statements _activeBuyOrders[i] = BuyOrder(order).getBuyInfo(); and _historicalBuyOrders[i] = BuyOrder(order).getBuyInfo(); directly use i as the index.
+- Since i starts from offset, the indices from 0 to offset - 1 in the arrays remain uninitialized, leading to incorrect results or potential undefined behavior.

+### Impact
+
+**Runtime Exceptions**
+
+Iterating beyond the bounds of dynamically allocated memory results in an out-of-bounds access, which will cause a contract call to revert.
+
+**Incorrect Data**
+
+Due to the wrong index calculation in the assignment, the resulting arrays may have uninitialized elements or unexpected empty slots.
+
+**Increased Gas Costs**
+
+The incorrect implementation may unnecessarily allocate and iterate over memory, leading to inefficient gas usage.
+
+### PoC
+
+```solidity
+function getActiveBuyOrders(
+ uint offset,
+ uint limit
+) public view returns (BuyOrder.BuyInfo[] memory) {
+ uint length = limit;
+ if (limit > activeOrdersCount) {
+ length = activeOrdersCount;
+ }
+
+ BuyOrder.BuyInfo[] memory _activeBuyOrders = new BuyOrder.BuyInfo[](length - offset);
+
+ for (uint i = offset; i < length; i++) {
+ address order = allActiveBuyOrders[i];
+ _activeBuyOrders[i - offset] = BuyOrder(order).getBuyInfo();
+ }
+
+ return _activeBuyOrders;
+}
+
+```
+Similar changes to getHistoricalBuyOrder potentially solves the issue

+# Improper Handling of Fee-on-Transfer Tokens in the deposit Function in `TaxTokenReceipt.sol`
+
+## Summary
+The `deposit` function does not correctly handle fee-on-transfer tokens. The function compares the expected transferred amount (`amount`) with the actual difference in the contract’s balance (`difference`). This strict comparison (`require(difference >= amount)`) causes the function to revert when dealing with tokens that impose a transfer fee, as the actual tokens received (`difference`) will always be less than the `amount` specified by the sender due to the fee deduction.
+
+## Vulnerability Detail
+
+Here is the relevant portion of the [deposit](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L59-L75) function:
+```js
+function deposit(uint amount) public nonReentrant returns (uint) {
+ uint balanceBefore = ERC20(tokenAddress).balanceOf(address(this));
+ SafeERC20.safeTransferFrom(
+ ERC20(tokenAddress),
+ msg.sender,
+ address(this),
+ amount
+ );
+ uint balanceAfter = ERC20(tokenAddress).balanceOf(address(this));
+ uint difference = balanceAfter - balanceBefore;
+ require(difference >= amount, "TaxTokensReceipts: deposit failed"); // @audit
+ tokenID++;
+ tokenAmountPerID[tokenID] = amount;
+ _mint(msg.sender, tokenID);
+ emit Deposited(msg.sender, amount);
+ return tokenID;
+}
+```
+
+`Fee-on-transfer` tokens deduct a percentage of the tokens during every transfer. For example, if the user specifies an amount of 100 tokens to deposit and the token has a 2% transfer fee, the actual tokens received by the contract (`difference`) will only be 98 tokens.
+
+The strict comparison in the require statement:
+```js
+require(difference >= amount, "TaxTokensReceipts: deposit failed");
+```
+requires the contract to receive at least the full amount. This condition will fail for fee-on-transfer tokens, causing the function to revert even though the transfer was otherwise successful.
+
+Additionally, the function records the user-provided amount instead of the actual received amount (difference), which may create further inconsistencies if the value is used later.
+
+## Impact
+Incompatibility with Fee-on-Transfer Tokens: Users cannot deposit tokens that charge a fee on transfer, making the contract unusable for such tokens.
+
+## Tools
+Manual Review
+
+## Recommendation
+**Changed require Condition:** The condition `difference > 0` ensures that the function does not revert for fee-on-transfer tokens and only checks that some tokens were received.

+# For loop can be optimized
+
+### Summary
+
+The `getActiveAuctionOrders` function contains redundant calculations within its loop, which can be improved for efficiency and gas optimization. the current implementation calculates `offset + i` in every iteration of the loop to access elements from the `allActiveAuctionOrders` array. This operation introduces unnecessary overhead. By modifying the loop structure and indexing logic, we can eliminate these redundant calculations, making the function more optimized and easier to understand.
+
+
+
+### Root Cause

+# Attacker is able to delete all active lend order records just by cancelling the same order multiple times.
+
+### Summary
+
+Anyone can cancel an existing order just by calling [DLOImplementation.cancelOffer()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L144) function as long as the caller is the lend order owner and there is fund available. A lend order owner can add funds to an existing lend order by calling [DLOImplementation.addFunds()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L162). None of the mentioned functions check whether the lend order is active or not. By exploiting this flaw an attacker can delete all active lend order records and bring `activeOrdersCount` down to 0 just by repeating "cancelOffer & addFunds" step.
+
+### Root Cause
+
+[DLOImplementation.cancelOffer()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L144) function is as follows:
+```solidity
+ function cancelOffer() public onlyOwner nonReentrant {
+ uint availableAmount = lendInformation.availableAmount;
+ lendInformation.perpetual = false;
+ lendInformation.availableAmount = 0;
+ require(availableAmount > 0, "No funds to cancel");
+ isActive = false;
+
+ SafeERC20.safeTransfer(
+ IERC20(lendInformation.principle),
+ msg.sender,
+ availableAmount
+ );
+ IDLOFactory(factoryContract).emitDelete(address(this));
+ IDLOFactory(factoryContract).deleteOrder(address(this));
+ // emit canceled event on factory
+ }
+```
+As we can see this does not check whether the order has already been cancelled or not.
+
+[DLOImplementation.addFunds()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L162) function is as follows:
+```solidity
+// only loans or owner can call this functions --> add more funds to the offer
+ function addFunds(uint amount) public nonReentrant {
+ require(
+ msg.sender == lendInformation.owner ||
+ IAggregator(aggregatorContract).isSenderALoan(msg.sender),
+ "Only owner or loan"
+ );
+ SafeERC20.safeTransferFrom(
+ IERC20(lendInformation.principle),
+ msg.sender,
+ address(this),
+ amount
+ );
+ lendInformation.availableAmount += amount;
+ IDLOFactory(factoryContract).emitUpdate(address(this));
+ }
+```
+This too does not check whether the order has already been cancelled or not.
+
+[DLOFactory.deleteOrder()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207) is as follows:
+```solidity
+function deleteOrder(address _lendOrder) external onlyLendOrder {
+ uint index = LendOrderIndex[_lendOrder];
+ LendOrderIndex[_lendOrder] = 0;
+
+ // switch index of the last borrow order to the deleted borrow order
+ allActiveLendOrders[index] = allActiveLendOrders[activeOrdersCount - 1];
+ LendOrderIndex[allActiveLendOrders[activeOrdersCount - 1]] = index;
+
+ // take out last borrow order
+
+ allActiveLendOrders[activeOrdersCount - 1] = address(0);
+
+ activeOrdersCount--;
+ }
+```
+It switches position of the last order with the deleted one, decreases `activeOrdersCount` by 1 and removes cancelled lend order record from both `allActiveLendOrders` and `LendOrderIndex`.
+
+### Internal pre-conditions
+N/A
+
+### External pre-conditions
+N/A
+
+### Attack Path
+
+1. Create 3 lend orders by calling `DLOFactory.createLendOrder()`.
+2. Cancel the first order by calling `LendOrder1.cancelOffer()`. Notice that the first lend order record is removed and `activeOrdersCount` is now 2.
+3. Add funds to the first order by calling `LendOrder1.addFunds()`.
+4. Cancel the first order again. Notice that this time the 3rd lend order record is gone and `activeOrdersCount` is now 1.
+5. Add funds to the first order again.
+6. Cancel the first order again. Notice that this time 2nd lend order record is gone and `activeOrdersCount` is now 0.
+7. Notice that no order shows up in public `DLOFactory.getActiveOrders()` call result either.
+
+### Impact
+
+1. Attacker can remove records of all active lend orders.
+2. Attacker can bring `activeOrdersCount` down to 0.
+3. No active order shows up in public `DLOFactory.getActiveOrders()` call result either.

+# Principle Incentive DoS Because of Bribe Token Indexing
+
+### Summary
+Token indexing check will cause a denial of service impact for protocol users as malicious actors will block legitimate principle incentivization by exploiting the first-mover advantage in bribe token registration.
+
+### Root Cause
+In `DebitaIncentives.sol` at https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L257 the choice to use mapping for `hasBeenIndexedBribe` that only tracks epoch and incentive token (without principle) is a mistake as it prevents multiple principles from using the same bribe token within an epoch.
+
+```solidity
+mapping(uint => mapping(address => bool)) public hasBeenIndexedBribe;
+// Mapping: epoch => incentivizeToken => bool
+```
+
+### Internal pre-conditions
+_No response_
+
+### Attack Path
+1. Attacker identifies a commonly used bribe token (e.g., USDC) and a target epoch
+2. Attacker calls `incentivizePair()` with:
+ - A principle token
+ - The identified bribe token
+ - A minimal amount
+ - The target epoch
+3. `hasBeenIndexedBribe[epoch][incentivizeToken]` is set to true
+4. When legitimate users try to incentivize different principles with the same bribe token:
+ - The `hasBeenIndexedBribe` check fails
+ - Their tokens are transferred but not properly indexed
+ - The incentive becomes unclaimable
+
+### Impact
+The affected users suffer a total loss of deposited bribe tokens when attempting to incentivize principles after the attacker has claimed the token for an epoch. Additionally, the ability to properly incentivize principles using popular bribe tokens is permanently blocked for that epoch, disrupting the protocol's incentive mechanism.

+# `TaxTokensReceipt.sol` is incompatible with fee-on-transfer tokens
+
+## Vulnerability Detail
+
+According to the contest readme, FoT tokens will be used in `TaxTokenReceipt.sol`
+> We will interact with :
+
+ > any ERC20 that follows exactly the standard (eg. 18/6 decimals)
+ > Receipt tokens (All the interfaces from "contracts/Non-Fungible-Receipts/..")
+ > USDC and USDT
+ > Fee-on-transfer tokens will be used only in TaxTokensReceipt contract
+
+ Fee-on-transfer tokens deduct a percentage of the transferred tokens as a fee, meaning the receiving address (in this case, the contract) will always receive fewer tokens than the amount specified in the `safeTransferFrom` call.
+
+ The `deposit` function fails to properly account for tokens that apply a fee during transfers. Specifically, the function expects the full amount of tokens to be received by the contract, but with fee-on-transfer tokens, a portion of the transferred tokens is deducted as a fee. This discrepancy causes the function to revert, preventing deposits of such tokens.
+
+ The require condition in the `deposit` function enforces that the contract must receive at least the full `amount` specified:
+ [TaxTokensReceipt.sol#L69](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/TaxTokensReceipts/TaxTokensReceipt.sol#L69)
+
+ ```js
+function deposit(uint amount) public nonReentrant returns (uint) {
+ uint balanceBefore = ERC20(tokenAddress).balanceOf(address(this));
+ SafeERC20.safeTransferFrom(
+ ERC20(tokenAddress),
+ msg.sender,
+ address(this),
+ amount
+ );
+ uint balanceAfter = ERC20(tokenAddress).balanceOf(address(this));
+ uint difference = balanceAfter - balanceBefore;
+@> require(difference >= amount, "TaxTokensReceipts: deposit failed");
+ tokenID++;
+ tokenAmountPerID[tokenID] = amount;
+ _mint(msg.sender, tokenID);
+ emit Deposited(msg.sender, amount);
+ return tokenID;
+}
+```
+This condition will fail for fee-on-transfer tokens, resulting in a transaction revert.
+
+## Impact
+FoT tokens cannot be used in `TaxTokenReceipt.sol`
+
+## Recommendation
+Modify the require statement to correctly account for FoT tokens.

+# Risks of Uninitialized DebitaContract in Ownerships Contract
+
+### Summary
+
+The Ownerships contract has a critical issue: the DebitaContract address is not initialized in the constructor or at the time of deployment. It retains its default value of address(0) until explicitly set via the setDebitaContract function. This oversight can introduce several vulnerabilities and operational risks.
+
+
+### Root Cause
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLoanOwnerships.sol#L17
+
+- The DebitaContract address defaults to address(0) (zero address) until it is explicitly set using the setDebitaContract function.
+- The setDebitaContract function can only be called once due to the onlyOwner modifier coupled with the ! initialized check. However, until the function is called, the contract operates with an invalid DebitaContract address.
+
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+This could potentially lead to
+**Unauthorized minting via mint function:**
+
+- The mint function relies on the onlyContract modifier, which checks that msg.sender equals DebitaContract.
+- If DebitaContract is address(0), any call with msg.sender == address(0) (which could occur due to contract calls or inadvertent issues) would bypass this check, leading to unauthorized minting.
+
+**Unrestricted Burning via burn Function:**
+
+- The burn function calls IDebitaAggregator(DebitaContract).isSenderALoan(msg.sender) to validate the caller.
+- With DebitaContract == address(0), this results in a call to a nonexistent contract, which will revert every time. Thus, burning functionality becomes inoperable until DebitaContract is correctly set.
+
+**Operational Delays:**
+
+If the DebitaContract address is not set promptly, critical functionalities such as minting and burning cannot be used, potentially halting operations dependent on this contract.
+
+**Exploitation of Timing Gaps**
+
+There is a timing gap between contract deployment and setDebitaContract execution. During this period:
+- The onlyContract modifier effectively blocks all minting.
+- However, attackers or malicious actors could exploit other vulnerabilities or assumptions made based on the contract's functionality.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+- Initialize DebitaContract in Constructor or Deployment Script
+- Add Validity Checks in against default address

+# Hardcoded argument `age` in Pyth's `getPriceNoOlderThan` will lead to a dos due to `StalePrice` reverts
+
+### Summary
+
+Using a hardcoded age parameter of 600 seconds in the `getPriceNoOlderThan` function causes transactions to revert with a `StalePrice` error when Pyth price feeds are not updated within that timeframe for certain feeds and or on certain L2 chains. This will result in a DOS for the protocol since the oracle will be used to call `matchOffersV3` in the `DebitaV3Aggregator` contract.
+
+### Root Cause
+
+In [`DebitaPyth.sol`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L32-L35), the `getThePrice` function calls `pyth.getPriceNoOlderThan(_priceFeed, 600)` with a hardcoded age of 600 seconds. On some L2 chains like Optimism and Arbitrum, Pyth price feeds may not update within this timeframe, causing the function to revert with a StalePrice error.
+
+### Impact
+
+When the Pyth oracle is used, the users cannot match a borrower with lenders by calling `matchOffersV3` since the `getPriceFrom` used for ratio calculation will revert. This leads to a dos of the most important functionality of the protocol.
+
+### PoC
+
+Attempting to retrieve the price of `AERO/USD` pair using `getPriceNoOlderThan` with an age of 600 seconds on base chain using [the Pyth interface](https://api-reference.pyth.network/price-feeds/evm/getPriceNoOlderThan) :
+
+
+Now for Arbitrum and Optimism :
+
+The same function call reverts with `StalePrice` because the price feed hasn't been updated within the required timeframe.
+
+Using the `getPriceUnsafe` in the [interface](https://api-reference.pyth.network/price-feeds/evm/getPriceUnsafe) shows that the `publishTime` indeed is different for different chains.
+
+
+### Mitigation
+
+To mitigate this issue:
+
+- Either use `getPriceUnsafe` with Custom Staleness Checks instead of `getPriceNoOlderThan`
+- Make the `age` parameter configurable depending on the feed and chain.

+# Attacker will exploit incorrect price calculation in DebitaPyth to drain protocol funds through overvalued loans
+
+### Summary
+
+Missing exponent handling in DebitaPyth.sol will cause severe asset overvaluation leading to protocol insolvency as attackers can borrow against artificially inflated collateral values due to incorrect price calculations from Pyth oracle feed.
+
+### Root Cause
+
+In [DebitaPyth.sol#L24-41](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L24-L41), the `getThePrice()` function fails to account for the exponent in Pyth's price data:
+
+```solidity
+function getThePrice(address tokenAddress) public view returns (int) {
+ // ...
+ PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ _priceFeed,
+ 600
+ );
+ // ...
+ return priceData.price; // Returns raw price without applying exponent
+}
+```
+
+Per [Pyth's API documentation](https://api-reference.pyth.network/price-feeds/evm/getPriceNoOlderThan), price values must be adjusted using the exponent from the price feed. The current implementation ignores `priceData.expo`, leading to massive price overvaluation.
+
+For example:
+- Pyth returns: price = 123, expo = -3
+- Actual price should be: 123 * 10^(-3) = 0.123 USD
+- Current implementation returns: 123 USD (1000x overvaluation)
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Attacker identifies an asset where Pyth returns a price with negative exponent
+ - Example: price=123, expo=-3 (true price $0.123)
+2. Attacker deposits this asset as collateral
+3. Protocol values collateral at $123 instead of $0.123
+4. Attacker borrows against overvalued collateral
+5. Attacker defaults on loan, leaving protocol with bad debt
+
+### Impact
+
+High. This vulnerability fundamentally breaks the protocol's economic security:
+
+1. All assets are severely overvalued (potentially by orders of magnitude)
+2. Attackers can borrow against inflated collateral values
+3. Liquidation thresholds are incorrectly calculated
+4. Protocol accumulates bad debt when true asset values are revealed
+
+The impact is critical because:
+- It affects all assets using Pyth oracle
+- Exploitation requires no special conditions
+- Results in direct loss of funds
+- Recovery from bad debt may be impossible
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+## Recommended Mitigation
+Modify `getThePrice()` to properly handle both positive and negative exponents:
+
+```diff
+function getThePrice(address tokenAddress) public view returns (int) {
+ bytes32 _priceFeed = priceIdPerToken[tokenAddress];
+ require(_priceFeed != bytes32(0), "Price feed not set");
+ require(!isPaused, "Contract is paused");
+
+ PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(_priceFeed, 600);
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+ require(priceData.price > 0, "Invalid price");
+
+- return priceData.price;
++ // Handle both positive and negative exponents correctly
++ if (priceData.expo >= 0) {
++ return priceData.price * int(10 ** uint(priceData.expo));
++ } else {
++ return priceData.price / int(10 ** uint(-priceData.expo));
++ }
+}
+```
+
+This fix properly handles both cases:
+- For positive exponents (e.g., expo = 2): Multiplies the price by 10^expo
+- For negative exponents (e.g., expo = -3): Divides the price by 10^(-expo)
+
+For example:
+- If price = 123, expo = -3: Returns 123 / 10^3 = 0.123
+- If price = 123, expo = 2: Returns 123 * 10^2 = 12300

+# Missing updates of states when owner of NFT receipt making ERC721 related action such as transferring
+
+### Summary
+
+States variables in veNFTAerodrome should be take cares if there are ERC721 derived actions such as safeTransferFrom/transferFrom functions.
+
+### Root Cause
+
+The NFT receipt contract derives from ERC721Enumerable contract which is decendant of ERC721. The parent ERC721 contract contains public exposed methods such as transferFrom, safeTransferFrom functions.
+In the cases of receipt being transferred, the contract must take consideration of the states change such as balanceOfManager, indexPosition, ownenTokens.
+

+
+The NFT receipt contract may have states inconsistence if there are transferring actions of receipts. And the vault manager should take special cares if the owner of the receipt has changed since transferring.

+
+_No response_
+
+### Mitigation
+
+Consider overriding the transferFrom/safeTransferFrom function from ERC721.sol, alternatively, overriding _update function in Receipt-veNFT should works too. Update state variables such ownedTokens, indexPosition, balanceOfManager, and handles the vault manager address in vault.

+# State Variable Shadowing in changeOwner Function
+
+### Summary
+
+A bug was discovered in the `DebitaV3Aggregator` and `auctionFactoryDebita` contract, where the `changeOwner` function fails to update the state variable `owner`. This issue arises due to shadowing of the state variable `owner` by a function parameter with the same name. As a result, the intended update to the contract's ownership does not occur, leading to potential operational issues and security concerns as owner can never be changed after deployment
+
+### Root Cause
+
+The problematic code resides in the `changeOwner` function
+1. In `DebitaV3Aggregator`, in lines [682-686](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682-L686):
+```solidity
+function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+```
+2. In `auctionFactoryDebita` , in lines [218-222](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L218-L222):
+```solidity
+function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+ }
+```
+
+In both of these cases, the function parameter `owner` shadows the state variable `owner`. Inside the function, all references to `owner` refer to the parameter instead of the state variable. This line:
+```solidity
+owner = owner;
+```
+performs a self-assignment of the parameter `owner` and does not update the state variable `owner`.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+1. Owner cannot be changed after deployment and deployer becomes the permanent owner.
+2. If a new owner is intended to assume control, their inability to do so can result in failure to implement updates to key contract parameters and the existing owner retaining control even when they should no longer have authority
+
+
+### PoC
+
+1. Create a new file in the test folder: `Poc.t.sol`
+2. Paste the following code:

+```
+3. Run `forge test --mt testAggregatorChangeOwner` and `forge test --mt testAuctionChangeOwner`
+
+### Mitigation

+# DebitaIncentives::updateFunds will exit prematurely and not update whitelisted pairs causing loss of funds to lenders and borrowers
+
+### Summary
+
+The `DebitaIncentives::updateFunds` function iterates over the `lenders` array, verifying whether the principle and collateral pair for each lend offer is whitelisted. If a non-whitelisted pair is encountered, the function exits prematurely, causing it to skip the processing of all subsequent pairs, even if they are valid and whitelisted.
+
+This causes the loss of potential funds for lenders and borrowers, as they would have been eligible to claim incentives had the function processed all valid pairs. Specifically, the `lentAmountPerUserPerEpoch`, `totalUsedTokenPerEpoch`, and `borrowAmountPerEpoch` mappings are not updated.
+
+
+### Root Cause
+
+In [DebitaIncentives.sol#L317](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L317) the `return` keyword is used, stopping the entire function, not just the iteration, ignoring the subsequent elements in the `informationOffers` array.
+
+
+### Internal pre-conditions
+
+- At least one lend offer be active with the following conditions (non-whitelisted pair lend offer):
+ - `principle` and `acceptedCollaterals` pair is not whitelisted in the `DebitaIncentives` contract.
+ - `lonelyLender` must be false.
+ - `availableAmount` is greater than `0`.
+
+- At least one lend offer be active with the following conditions (whitelisted pair lend offer):
+ - `principle` and `acceptedCollaterals` pair is whitelisted in the `DebitaIncentives` contract.
+ - `lonelyLender` must be false.
+ - `availableAmount` is greater than `0`.
+
+- At least one borrow order must be active with the following conditions:
+ - `acceptedPrinciples` must include at least a whitelisted principle and at least a non-whitelisted principle.
+ - `collateral` when paired with the principle, it must be whitelisted.
+ - `availableAmount` is greater than `0`.
+
+- The terms of the borrow order must allow it to be successfully matched with both types of lend offers in a single `DebitaV3Aggregator::matchOffersV3` call.
+
+- `DebitaV3Aggregator` must not be paused.
+
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. `DebitaIncentives` contract owner whitelists pair of principle and collateral calling `DebitaIncentives::whitelListCollateral`
+2. A user calls `DebitaIncentives::incentivizePair` to incentivize the already whitelisted principle.
+ This function transfers the tokens given as incentives from the user to the `DebitaIncentives` contract. The amount of incentives is updated:
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L277-L285
+
+```solidity
+
+ if (lendIncentivize[i]) {
+ lentIncentivesPerTokenPerEpoch[principle][
+ hashVariables(incentivizeToken, epoch)
+ ] += amount;
+ } else {
+ borrowedIncentivesPerTokenPerEpoch[principle][
+ hashVariables(incentivizeToken, epoch)
+ ] += amount;
+ }
+
+```
+
+3. Another user calls `DebitaV3Aggregator::matchOffersV3` to match a previously created borrow order with one lend offer that has a non-whitelisted pair and another lend offer that has a whitelisted pair.
+Inside `matchOffersV3`, the `DebitaIncentives::updateFunds` function is called to update the funds of the lenders and borrowers. `offers` array contains the principle of each accepted lend offer, and it is passed as an argument.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L631-L636
+
+```solidity
+
+ DebitaIncentives(s_Incentives).updateFunds(
+@> offers,
+ borrowInfo.collateral,
+ lenders,
+ borrowInfo.owner
+ );
+
+```
+
+ `updateFunds` function iterates over the array, and checks if the principle and collateral pair is whitelisted. If the pair is not whitelisted, the `return` keyword halts the entire function. The offer containing the non-whitelisted principle is at index `0`, so the function stops before the iteration reaches the offer at index `1` that has the whitelisted principle. This stops `lentAmountPerUserPerEpoch`, `totalUsedTokenPerEpoch` and `borrowAmountPerEpoch` from being updated.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L306-L341
+
+```solidity
+
+ function updateFunds(
+ infoOfOffers[] memory informationOffers,
+ address collateral,
+ address[] memory lenders,
+ address borrower
+ ) public onlyAggregator {
+ for (uint i = 0; i < lenders.length; i++) {
+ bool validPair = isPairWhitelisted[informationOffers[i].principle][
+ collateral
+ ];
+ if (!validPair) {
+@> return;
+ }
+ address principle = informationOffers[i].principle;
+
+ uint _currentEpoch = currentEpoch();

+
+ emit UpdatedFunds(
+ lenders[i],
+ principle,

+ }
+ }
+
+```
+
+As the mappings are not updated, the beneficiary lender or borrower can't claim the incentives:

+
+Steps to reproduce:
+
+1. Create a file `UpdateFundsTest.t.sol` inside `Debita-V3-Contracts/test/local/ `and paste the PoC code.
+
+2. Run the test in the terminal with the following command:
+
+`forge test --mt testUpdateFunds -vv`
+
+### Mitigation
+
+Change the `return` keyword in `DebitaIncentives::addFunds`
+
+
+```diff
+function updateFunds(

+ address collateral,
+ address[] memory lenders,
+ address borrower

+ collateral
+ ];
+ if (!validPair) {
+- return;
++ continue;
+ }
+ address principle = informationOffers[i].principle;
+
+ uint _currentEpoch = currentEpoch();
+
+ lentAmountPerUserPerEpoch[lenders[i]][
+ hashVariables(principle, _currentEpoch)
+ ] += informationOffers[i].principleAmount;
+ totalUsedTokenPerEpoch[principle][

+
+ emit UpdatedFunds(
+ lenders[i],
+ principle,
+ collateral,
+ borrower,
+ _currentEpoch
+ );
+ }
+ }
+```
+
+After applying the change, running the test case provided in the PoC will output the following logs:

+# Users can still add funds to cancelled/fullfiled offers and inherently redelete that offer which would cause other offers(last ones in the mapping) to be deleted
+
+### Summary
+
+In DLOImplementation.sol, the `addFunds` function allows users to add funds to a lend offer regardless of its active status. If a lend offer has been cancelled or fully utilized (availableAmount == 0), calling addFunds will increase availableAmount, and subsequently, if the offer is not perpetual, a subsequent call to the `cancelOffer` function will cause the `lendOrder` to be redeleted which would cause collisions between other others due to how the deletion algorithm was implemented.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207-L220
+
+`DebitaLendOfferFactory` deletes `lendOrders` by moving the deleteded order to index 0 and the last order to the previous index of the deleted order before subsequently decreasing the `activeOrdersCount` If an address gets deleted more that once that exposes a huge flaw in this logic since every `last lendOrder` will keep moving to index `0`. An attacker can repeat this process as many times as they want which would further damage the system since:
+- Multiple `lendOrders` will share the same index
+- Unintended `lendOrders` will get "deleted"
+- `activeOrderCount` will not be able to truly and accurately reflect the number of active orders
+
+The combination of the above issues would render any kind of record being kept by the protocol useless and grossly misleading, as well as other systems that would rely on it.
+
+### Root Cause
+
+- The ability of a lender to addFunds to an already Cancelled/Fulfilled `lendOrder`
+
+### Internal pre-conditions
+
+1. Attacker will have to create a `lendOrder`
+2. Attacker cancels or waits for the order to be fullfiled
+3. Attacker calls the `addFunds` function in DLO-Implementation contract and then has the ability to cancel again.
+4. Attacker repeats these steps over and over again. (twice is enough to cause harm to the protocol)

+# Incorrect Price Scaling for Pyth Oracle Feeds in DebitaV3Aggregator.sol
+
+# Incorrect Decimal Scaling for Pyth Oracle Feeds in DebitaV3Aggregator.sol
+
+## Summary
+
+The `matchOffersV3()` function in `DebitaV3Aggregator.sol` incorrectly handles Pyth oracle price feeds by failing to account for the price exponents. When calculating collateral-to-principle ratios, the function uses raw price values without applying the Pyth-specific decimal exponent, leading to severely incorrect valuations. This affects core functionality like LTV calculations and order matching conditions.
+
+## Vulnerability Detail
+
+Pyth oracle feeds return prices in a fixed-point numeric format where the true price must be calculated using both a price value and an exponent. Let’s see an example with [ETH/USD](https://www.pyth.network/price-feeds/crypto-eth-usd):
+
+```solidity
+// Example showing different oracle price formats for ETH/USD price of $3,474.45
+
+// 1. Chainlink Price Feed
+chainlinkPrice = 347445000000 // $3,474.45
+chainlinkDecimals = 8
+actualChainlinkPrice = 347445000000 * 10^8 = 34744.45 USD
+
+// 2. Pyth Price Feed
+pythPrice = 347445000 // $3,474.45
+pythExponent = -5 // Price must be multiplied by 10^(-5)
+actualPythPrice = 347445000 * 10^(-5) = 3474.45 USD
+
+// In DebitaV3Aggregator.sol when calculating ratios:
+
+// Current incorrect calculation:
+priceCollateral = getPriceFrom(oracle, collateral); // e.g. 347445000 from Pyth
+pricePrinciple = getPriceFrom(oracle, principle); // e.g. 100000000 from Chainlink
+
+// Raw division without accounting for decimals:
+ratio = (priceCollateral * 10^8) / pricePrinciple; // WRONG!
+
+// Correct calculation should be:
+collateralDecimals = getDecimals(collateralOracle); // e.g. -5 for Pyth
+principleDecimals = getDecimals(principleOracle); // e.g. 8 for Chainlink
+
+//
+normalizedCollateralPrice = priceCollateral * 10^(collateralDecimals);
+normalizedPrinciplePrice = pricePrinciple * 10^(principleDecimals);
+
+ratio = (normalizedCollateralPrice * 10^8) / normalizedPrinciplePrice;
+
+```
+
+Refer to [Pyth Best Practices](https://docs.pyth.network/price-feeds/best-practices#fixed-point-numeric-representation) docs.
+
+Refer to [Pyth Price-feeds](https://www.pyth.network/price-feeds)
+
+In the `matchOffersV3` function, prices are used to calculate ratios for collateral valuation and LTV checks. Let’s see where this happens:
+
+```solidity
+// From DebitaV3Aggregator.sol - matchOffersV3()
+if (borrowInfo.oraclesPerPairActivated[indexForPrinciple_BorrowOrder[i]]) {
+ // get price of collateral using borrow order oracle
+ uint priceCollateral_BorrowOrder = getPriceFrom(
+ borrowInfo.oracle_Collateral,
+ borrowInfo.valuableAsset
+ );
+
+ // get principle price
+ uint pricePrinciple = getPriceFrom(
+ borrowInfo.oracles_Principles[indexForPrinciple_BorrowOrder[i]],
+ principles[i]
+ );
+
+ /*
+ @audit - Both prices could be from Pyth but exponents are not considered
+ Example: If collateral price is 12276250 (122.76 with exp=-5)
+ and principle price is 1500000 (15.00 with exp=-5)
+ The calculation below will use raw numbers leading to wrong ratios
+ */
+ uint ValuePrincipleFullLTVPerCollateral = (priceCollateral_BorrowOrder *
+ 10 ** 8) / pricePrinciple;
+
+ // take 100% of the LTV and multiply by the LTV of the principle
+ uint value = (ValuePrincipleFullLTVPerCollateral *
+ borrowInfo.LTVs[indexForPrinciple_BorrowOrder[i]]) / 10000;
+}
+
+```
+
+Later in the same function, when validating lend orders:
+
+```solidity
+if (lendInfo.oraclesPerPairActivated[collateralIndex]) {
+ // calculate the price for collateral and principles with each oracles provided by the lender
+ uint priceCollateral_LendOrder = getPriceFrom(
+ lendInfo.oracle_Collaterals[collateralIndex],
+ borrowInfo.valuableAsset
+ );
+ uint pricePrinciple = getPriceFrom(
+ lendInfo.oracle_Principle,
+ principles[principleIndex]
+ );
+
+ // @audit - Same issue here with raw price values
+ uint fullRatioPerLending = (priceCollateral_LendOrder *
+ 10 ** 8) / pricePrinciple;
+ uint maxValue = (fullRatioPerLending *
+ lendInfo.maxLTVs[collateralIndex]) / 10000;
+}
+
+```
+
+In both cases, if Pyth oracle is used, the raw price values are used without considering their exponents.
+
+### Impact
+
+This issue can have multiple impacts on the protocol involving bad calculation on different places like:
+
+- Wrong incentives calculation
+- Liquidation risks
+- Undercollaterallized loans
+- Incorrect loan to value (LTV)

+
+## Tool Used
+
+Manual Review
+
+## Recommendation
+
+Update `matchOffersV3()` function in `DebitaV3Aggregator`to be able to use correct decimals by getting values from `getDecimals()` for each oracle.
+
+This is necessary since each oracle contract will return different decimal values and we need to avoid wrong calculations.

+
+### Root Cause
+
+TaxTokensReceipt.sol::deposit() checks that amount of token received is not less than amount taken from the sender, which will revert when using fee-on-transfer tokens (usage of such tokens is stated in the README).

+# Previous owner can steal unclaimed bribes from new owner of veNFTVault
+
+### Summary
+
+Previous owner can steal unclaimed bribes from new owner of `veNFT`, because transfering ownership of `veNFT` does not change the manager (which can claim bribes, vote).
+
+### Root Cause
+
+[Link](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/Non-Fungible-Receipts/veNFTS/Aerodrome/Receipt-veNFT.sol#L128-L142)
+```solidity
+function claimBribesMultiple(
+ address[] calldata vaults,
+ address[] calldata _bribes,
+ address[][] calldata _tokens
+ ) external {
+ for (uint i; i < vaults.length; i++) {
+ require(
+ msg.sender == veNFTVault(vaults[i]).managerAddress(),
+ "not manager"
+ );
+ require(isVaultValid[vaults[i]], "not vault");
+ veNFTVault(vaults[i]).claimBribes(msg.sender, _bribes, _tokens);
+ emitInteracted(vaults[i]);
+ }
+ }
+```
+Each `veNFTVault.sol` has manager role, which by default is owner of `veNFTVault`:
+```solidity
+veNFTVault vault = new veNFTVault(
+ nftAddress,
+ address(this),
+ m_Receipt,
+ nftsID[i],
+ msg.sender
+ );
+//...
+ s_ReceiptID_to_Vault[m_Receipt] = address(vault);
+//...
+ _mint(msg.sender, m_Receipt);
+```
+But transfering ownership of `veNFTVault` by transfering `receiptID` does not change the manager - old manager can still call all of this functions: `voteMultiple()`, `claimBribesMultiple()`, `resetMultiple()`, `extendMultiple()` and `pokeMultiple()`. Main impact that old manager cam steal unclaimed bribes from new owner by calling `claimBribesMultiple()`:
+```solidity
+ function claimBribesMultiple(
+ address[] calldata vaults,
+ address[] calldata _bribes,
+ address[][] calldata _tokens
+ ) external {
+ for (uint i; i < vaults.length; i++) {
+ require(
+ msg.sender == veNFTVault(vaults[i]).managerAddress(),
+ "not manager"
+ );
+ require(isVaultValid[vaults[i]], "not vault");
+ veNFTVault(vaults[i]).claimBribes(msg.sender, _bribes, _tokens);
+ emitInteracted(vaults[i]);
+ }
+ }
+```
+
+### Internal pre-conditions
+
+None
+
+### External pre-conditions
+
+None
+
+### Attack Path
+
+- Malicious user wants to sell ownership of `veNFTVault`, which has for example 1000 USDC of unclaimed bribes;
+- Victim expects to become owner of `veNFTVault` and have the ability to claim unclaimed bribes, vote, and so on;
+- Malicious user claims bribes right after transfering `receiptID`, because he is still the manager of the vault;
+- Bribes are sent to previous malicious owner, not current holder of `receiptID`:
+```solidity
+SafeERC20.safeTransfer(
+ ERC20(_tokens[i][j]),
+ sender,
+ amountToSend
+ );
+```
+
+### Impact
+
+Previous owner can still call all of this functions: `voteMultiple()`, `claimBribesMultiple()`, `resetMultiple()`, `extendMultiple()` and `pokeMultiple()`. Main impact that manager (previous owner) cam steal unclaimed bribes from new owner by calling `claimBribesMultiple()`.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Override `transferFrom()` function in that way that it also changes `managerAddress` to new owner's address.

+# The chainlink oracle doesn't check if min/max answers are within the specified threshold
+
+### Summary
+
+The protocol will use 3 oracles for price retrievement and one of them is Chainlink oracle. However some Chainlink aggregators have a built-in circuit breaker to check if the price of an asset goes outside of a predetermined range. The reason for that is, if the price of an asset has a major drop in value the returned price from the oracle will continue to return the predetermined `minAnswer` instead of the actual price. An example would be the exploit of the [Venus Protocol & Blizz Finance](https://rekt.news/venus-blizz-rekt/) when LUNA crashed. Here we can see that min/max ranges are not validated also:
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/ce50bab1067574ae493f4062665b8e28611f2346/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L42-L45
+
+```javascript
+ function getThePrice(address tokenAddress) public view returns (int) {
+ ...
+ (, int price, , , ) = priceFeed.latestRoundData();
+
+ ...
+ require(price > 0, "Invalid price");
+ return price;
+ }
+```
+
+In the README is mentioned that the protocol will be deployed on Arbitrum also, so here are few examples that return `min/maxAnswer`:
+
+1. AAVE/USD - https://arbiscan.io/address/0x3c6AbdA21358c15601A3175D8dd66D0c572cc904#readContract
+2. AVAX/USD - https://arbiscan.io/address/0xcf17b68a40f10d3DcEedd9a092F1Df331cE3D9da#readContract
+3. SOL/USD - https://arbiscan.io/address/0x8C4308F7cbD7fB829645853cD188500D7dA8610a#readContract
+4. ETH/USD - https://arbiscan.io/address/0x3607e46698d218B3a5Cae44bF381475C0a5e2ca7#readContract

+# Incorrect Borrower/Lender Identification in `tokenURI()` Logic
+
+### Summary
+
+The [DebitaLoanOwnerships.sol::tokenURI()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLoanOwnerships.sol) function uses the parity of `tokenId` to differentiate between borrowers and lenders, setting ` _type` to "Borrower" for even tokenIds and "Lender" for odd tokenIds. However, this logic fails in scenarios where the assignment of tokenId does not conform to this parity rule, leading to incorrect metadata for the NFTs. This could mislead users and cause inconsistencies in loan representations.
+
+### Root Cause
+
+When a `matchOffer` is created through [matchOfferV3()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L502) the lendOrders get minted an `Ownership` token in a sequential order before the borrowerOrder.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+
+**Incorrect NFT Metadata:** Borrowers may be labeled as lenders and vice versa, causing confusion among users relying on the metadata for decision-making.
+
+### PoC
+
+If the loan created through `matchOfferV3()` is composed by 5 lenders and 1 borrower, then lenders will have tokenIds 1..5 and borrower 6. Therefore the lender in positions 2,4 will be granted a token with those ids. If you call the `DebitaLoanOwnership::tokenURI()` of tokens 2,4 the `_type` parameter will classify them as borrowers instead of lenders. Thus returning incorrect metadata for the token.
+
+### Mitigation
+
+
+A possible implemenetation will be to pass the `_type` as a boolean on `mint(address, boolean)` in [mint](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLoanOwnerships.sol#L34)and store it in a mapping;
+```solidity
+mapping(uint256 => bool) public isBorrower;
+string memory _type = isBorrower[tokenId] ? "Borrower" : "Lender";

+# Risk of denial of service when claiming incentives
+
+### Summary
+
+In DebitaIncentive.sol, the users loop through claimIncentives() to claim their incentives allocated to them based on their activities within a given epoch, because this loop is unbounded and the number of users can grow, the amount of gas consumed is also unbounded.
+
+### Root Cause
+
+In DebitaIncentives.sol, https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L142-L214, the choice to use an unbounded loop to claim incentive is a mistake as it would cause DOS when called by a large number of users.
+
+### Internal pre-conditions
+
+1. Debita V3 team adds a new feature that improve lending and borrowing on their protocol
+2. Because of the improvement the number of user borrowing and lending grows dramatically
+3. Due to this large number of users wanting to claim their incentives, the claimIncentives() function cannot execute because it has reached block gas limit
+4. As a result, users are unable to claim incentives. The users will be DOSed until the next epoch.

+# A malicious user can delete all lend orders
+
+### Summary
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207-L220
+The protocol does not set the lend order as not legit after `DebitaLendOfferFactory::deleteOrder()` call which will lead to removing all lend orders, because `DebitaLendOffer-Implementation::cancelOffer()` can be called by the same lend order multiple times.
+
+### Root Cause
+
+The protocol does not set the lend order as not legit after the deletion.
+
+```solidity
+isLendOrderLegit[address(lendOffer)] = false;
+```
+
+Also, there is a `DebitaLendOffer-Implementation::addFunds()` function and using the both functions it is possible to call `DebitaLendOfferFactory::deleteOrder()` multiple times with same lend order.
+
+### Internal pre-conditions
+
+There should be at least one lend order for the attacker to act maliciously.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Random users create lend orders
+2. The malicious user creates a lend order with random input parameters only to pass the checks.
+3. Calls `cancelOffer()` function on the malicious lend order. `cancelOffer()` internally calls `deleteOrder()` which will delete the lend order and update the state variables.
+
+```solidity
+DebitaLendOffer-Implementation
+
+function cancelOffer() public onlyOwner nonReentrant {
+ uint availableAmount = lendInformation.availableAmount;
+ lendInformation.perpetual = false;
+ lendInformation.availableAmount = 0;
+ require(availableAmount > 0, "No funds to cancel");
+ isActive = false;
+
+ SafeERC20.safeTransfer(
+ IERC20(lendInformation.principle),
+ msg.sender,
+ availableAmount
+ );
+ IDLOFactory(factoryContract).emitDelete(address(this));
+ IDLOFactory(factoryContract).deleteOrder(address(this));
+ // emit canceled event on factory
+}
+```
+
+```solidity
+DebitaLendOfferFactory
+
+function deleteOrder(address _lendOrder) external onlyLendOrder {
+ uint index = LendOrderIndex[_lendOrder];
+ LendOrderIndex[_lendOrder] = 0;
+
+ // switch index of the last borrow order to the deleted borrow order
+ allActiveLendOrders[index] = allActiveLendOrders[activeOrdersCount - 1];
+ LendOrderIndex[allActiveLendOrders[activeOrdersCount - 1]] = index;
+
+ // take out last borrow order
+
+ allActiveLendOrders[activeOrdersCount - 1] = address(0);
+
+ activeOrdersCount--;
+}
+```
+
+4. After that the malicious user calls `addFunds()` in order to pass the check for `availableAmount` for `cancelOffer()` function.
+
+```solidity
+DebitaLendOffer-Implementation
+
+function addFunds(uint amount) public nonReentrant {
+ require(
+ msg.sender == lendInformation.owner ||
+ IAggregator(aggregatorContract).isSenderALoan(msg.sender),
+ "Only owner or loan"
+ );
+ SafeERC20.safeTransferFrom(
+ IERC20(lendInformation.principle),
+ msg.sender,
+ address(this),
+ amount
+ );
+ lendInformation.availableAmount += amount;
+ IDLOFactory(factoryContract).emitUpdate(address(this));
+}
+```
+
+5. Calls `cancelOffer()` on the same lend order again which deletes another lend order in factory.
+6. Repeats the process until there is not any lend order left or to delete a specific lend order.
+
+### Impact
+
+The affected critical functions are `acceptLendingOffer` and `cancelOffer`. If a user tries to cancel their lend order, it will be impossible. If the aggregator calls `acceptLendingOffer` and the available amount is zero, the deleting of the lend order will be impossible.

+# Users are unable to receive incentive rewards
+
+### Summary
+
+When the epoch is set to 1, calling incentivizePair will cause a revert, preventing the first users to borrow or lend from receiving rewards
+
+### Root Cause
+
+The root cause of this issue is that `currentEpoch` has a minimum value of 1, while the epoch value passed when calling `incentivizePair` must be greater than 1. As a result, the first users to borrow or lend will be unable to receive incentive rewards.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L245-L245

+
+### Internal pre-conditions
+
+Users need to call `matchOffersV3` to match orders when the `currentEpoch` function returns a value of 1.
+
+### External pre-conditions

+_No response_
+
+### Attack Path
+
+1. When `epoch` is 1, User A calls the `createBorrowOrder` function, and User B calls the `createLendOrder` function.
+2. When `epoch` is 1, calling `incentivizePair` will always revert, resulting in both User A and User B being unable to receive any incentive rewards.
+
+### Impact
+
+Neither borrowers nor lenders can receive incentive rewards, meaning that no one can earn rewards within the first 14 days of the protocol's launch
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Add incentive rewards for users either when currentEpoch is 1 or during the creation process

+# Borrowers and lenders are lose incentive tokens
+
+### Summary
+
+A lender can create an offer with any principal token and accepted collaterals, while a borrower creates an offer with collateral and accepted principals. The owner of the `DebitaIncentives.sol` contract decides whether a principal-collateral pair is whitelisted. When the `updateFunds` function is called from the aggregator contract and one of the pairs is not whitelisted, the function will exit, causing some borrowers and lenders to not receive incentive tokens.
+
+### Root Cause
+
+In [updateFunds](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L313-L318) there is a check that exit function:
+```solidity
+bool validPair = isPairWhitelisted[informationOffers[i].principle][
+ collateral
+ ];
+ if (!validPair) {
+--> return;
+ }
+```
+
+### Internal pre-conditions
+
+1. Lender_1 creates offer with principle - ETH, collaterals - USDT, USDC, DAI
+2. Lender_2 creates offer with principle - LINK, collaterals - USDT, DAI
+3. Borrower_1 creates offer with collateral - USDT, principle - ETH, LINK.
+4. The owner of `DebitaIncentives` calls the `whitelistCollateral` function and sets the ETH-USDT pair to true.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+5. The caller of the `matchOffersV3` function will match the [LINK-USDT] and [ETH-USDT] pairs. However, since the [LINK-USDT] pair isn't whitelisted, the call to `updateFunds()` will result in Lender_1 not receiving incentive tokens.
+```solidity
+bool validPair = isPairWhitelisted[informationOffers[i].principle][
+ collateral
+ ];
+ if (!validPair) {
+--> return; /// exit function cause [LINK-USDT] pair isn't whitelisted
+ }
+```
+
+### Impact
+
+Borrowers and lenders won't receive incentive tokens
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Consider changing `updateFunds` function:
+```diff
+ bool validPair = isPairWhitelisted[informationOffers[i].principle][
+ collateral
+ ];
+ if (!validPair) {
+- return;
++ continue;
+ }

+# Lender will loss his collateral share permanently when collateral in NFT
+
+### Summary
+
+Lender will loss his collateral share permanently when collateral in NFT
+
+### Root Cause
+
+Lenders can claim the collateral in default using [claimCollateralAsLender().](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L361) If collateral is NFT, it calls [claimCollateralAsNFTLender()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L374C5-L411C6) which returns bool on the basis of collateral is claimed or not.
+
+The problem is, its return value is not checked. As result, if claimCollateralAsNFTLender() returns false(indicating collateral is not claimed), it doesn't revert trx but burns the lenderID of the lender, preventing him to claim again
+```solidity
+ function claimCollateralAsLender(uint256 index) external nonReentrant {
+ LoanData memory m_loan = loanData;
+ infoOfOffers memory offer = m_loan._acceptedOffers[index];
+ IOwnerships ownershipContract = IOwnerships(s_OwnershipContract);
+ require(ownershipContract.ownerOf(offer.lenderID) == msg.sender, "Not lender");
+ // burn ownership
+@> ownershipContract.burn(offer.lenderID);
+ uint256 _nextDeadline = nextDeadline();
+
+ require(offer.paid == false, "Already paid");
+ require(_nextDeadline < block.timestamp && _nextDeadline != 0, "Deadline not passed");
+ require(offer.collateralClaimed == false, "Already executed");
+
+ // claim collateral
+ if (m_loan.isCollateralNFT) {
+@> claimCollateralAsNFTLender(index);
+ } else {
+ loanData._acceptedOffers[index].collateralClaimed = true;
+ uint256 decimals = ERC20(loanData.collateral).decimals();
+ SafeERC20.safeTransfer(
+ IERC20(loanData.collateral), msg.sender, (offer.principleAmount * (10 ** decimals)) / offer.ratio
+ );
+ }
+ Aggregator(AggregatorContract).emitLoanUpdated(address(this));
+ }
+```
+
+### Internal pre-conditions
+
+1. Collateral should be NFT
+2. Borrower should default on the debt
+
+### External pre-conditions
+
+None
+
+### Attack Path
+
+1. Suppose there are 4 lenders[L1, L2, L3, L4] and collateral is a NFT
+2. Borrower repaid the debt of L1 & L2 but defaulted on L3 & L4
+3. In order to claim collateral, NFT should be auctioned and then L3/4 can claim using claimCollateralAsLender()
+4. But, L3 called claimCollateralAsLender() before NFT is auctioned, which burns his lenderID(nft) and calls claimCollateralAsNFTLender()
+```solidity
+ function claimCollateralAsLender(uint256 index) external nonReentrant {
+...
+ // burn ownership
+ ownershipContract.burn(offer.lenderID);
+...
+
+ // claim collateral
+ if (m_loan.isCollateralNFT) {
+ claimCollateralAsNFTLender(index);
+ } else {
+...
+ }
+```
+5. Now, claimCollateralAsNFTLender() will return false because both if & else-if statement will not run because auction is not started(if-statement) & m_loan._acceptedOffers.length is > 1(else-if statement)
+```solidity
+ function claimCollateralAsNFTLender(uint256 index) internal returns (bool) {
+...
+ if (m_loan.auctionInitialized) {
+ // if the auction has been initialized
+ // check if the auction has been sold
+ require(auctionData.alreadySold, "Not sold on auction");
+
+ uint256 decimalsCollateral = IveNFTEqualizer(loanData.collateral).getDataByReceipt(loanData.NftID).decimals;
+
+ uint256 payment = (auctionData.tokenPerCollateralUsed * offer.collateralUsed) / (10 ** decimalsCollateral);
+
+ SafeERC20.safeTransfer(IERC20(auctionData.liquidationAddress), msg.sender, payment);
+
+ return true;
+ } else if (m_loan._acceptedOffers.length == 1 && !m_loan.auctionInitialized) {
+ // if there is only one offer and the auction has not been initialized
+ // send the NFT to the lender
+ IERC721(m_loan.collateral).transferFrom(address(this), msg.sender, m_loan.NftID);
+ return true;
+ }
+ return false;
+ }
+```
+6. Return value of claimCollateralAsNFTLender(), which is false is not checked in claimCollateralAsLender() and trx is executed successfully, burning lender's lenderID(nft) but without claiming his collateral
+
+### Impact
+
+Lender will lose his whole collateral if collateral NFT is not auctioned
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Check the return value of claimCollateralAsNFTLender() and execute the trx accordingly
+```diff
+ function claimCollateralAsLender(uint256 index) external nonReentrant {
+...
+ // claim collateral
+ if (m_loan.isCollateralNFT) {
+- claimCollateralAsNFTLender(index);
++ bool isClaimed = claimCollateralAsNFTLender(index);
++ require(isClaimed, "Not claimed");
+ } else {
+...

+# Lender will permanently lose collateral claim rights if they try to claim borrower’s NFT collateral before an auction is started due to incorrect state update
+
+### Summary
+
+In the event of a loan default (when a borrower fails to repay by the deadline) with NFT collateral, any lender involved in the loan can initiate the liquidation process by calling `createAuctionForCollateral()`.
+
+- This function starts a Dutch auction to sell the defaulted NFT.
+- Once a buyer purchases the NFT and the underlying locked tokens are transferred to the `DebitaV3Loan` contract, lenders should be able to claim their proportional share through the `claimCollateralAsLender()` function, which internally calls `ClaimCollateralAsNFTLender()`.
+
+However, there is a critical vulnerability in the `claimCollateralAsLender()` function that can result in permanent loss of collateral claim rights for lenders.
+
+### Root Cause
+
+The issue stems from an incorrect state update in `claimCollateralAsNFTLender()` where the function sets `collateralClaimed = true` **before** executing the actual claim logic.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L377
+
+- If the claim operation fails due to having multiple lenders and no auction being initialized, the `collateralClaimed` flag remains set to true, despite the failed claim.
+- The function then returns `false` without reverting, and `claimCollateralAsLender()` does not check this return value.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L410
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L361
+
+- This sequence of events leaves the lender in a state where they can never claim their share of the collateral, as the flag incorrectly indicates the collateral has already been claimed.
+
+This leaves the lender with:
+- A burned ownership token
+- No claimed collateral
+- No way to try claiming again
+
+Also, there is no onus on lenders ensuring that `createAuctionForCollateral()` has been called before they call `claimCollateralAsLender()` themselves, due to the fact that a single borrow can have multiple lend offers.
+
+### Internal pre-conditions
+
+- Loan uses NFT as collateral
+- Loan has multiple lenders
+- Borrower has failed to pay back the principle token amount and Loan is has defaulted
+- No auction has been initialized
+- Lender calls `claimCollateralAsLender()`
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+The impact of this vulnerability is severe as it creates a **permanent loss of lender rights** in defaulted loans.
+- Lenders not only fail to receive their collateral but also lose their ownership token in the process.
+- The lender becomes effectively locked out of the protocol, unable to recover their share of the defaulted collateral even after an auction is properly initialized.
+- This results in a **complete financial loss** equivalent to their lending position
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+In claimCollateralAsLender(), include a check on the return value from claimCollateralAsNFTLender.
+
+```solidity
+ function claimCollateralAsLender(uint index) external nonReentrant {
+ // other code
+ // claim collateral
+ if (m_loan.isCollateralNFT) {
+ require(claimCollateralAsNFTLender(index), "Claim failed")
+ } else {
+ // other code

+# Missing Confidence Interval Validation in DebitaPyth Oracle
+
+### Summary
+
+The missing confidence interval validation in `DebitaPyth.sol` will cause potential acceptance of untrusted or manipulated prices as the contract fails to validate the confidence interval from Pyth oracle, which could lead to incorrect price feeds being used for critical protocol operations.
+
+### Root Cause
+
+In [DebitaPyth.sol#L25-42](https://github.com/sherlock-audit/2024-11-debita-finance-v3-endless-c/tree/main/Debita-V3-Contracts/contracts/oracles/DebitaPyth.sol#L25-42), the `getThePrice` function retrieves price data from Pyth but only validates that:
+1. The price feed exists and is not paused
+2. The price feed is available
+3. The price is greater than 0
+
+However, it completely ignores the confidence interval (`conf`) field from the Pyth price feed, which is crucial for determining the reliability of the price.

+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+1. Pyth oracle needs to return a price with confidence interval (conf) greater than 2% of the price value
+2. The asset's price in Pyth oracle needs to experience high volatility within the 600-second window
+3. Multiple Pyth price publishers need to report significantly different prices for the same asset, causing high confidence interval
+
+### Attack Path
+
+1. The Pyth oracle returns a price with a very high confidence interval (high uncertainty)
+2. Due to the missing validation, the contract accepts this price as valid
+3. This could lead to using unreliable prices for protocol operations like:
+ - Collateral valuation
+ - Liquidation thresholds
+ - Asset pricing
+
+According to [Pyth's documentation](https://docs.pyth.network/price-feeds/best-practices#confidence-intervals), the confidence interval represents the spread or uncertainty in the price, and it's crucial to validate this value to ensure price reliability.
+
+### Impact
+
+The lack of confidence interval validation could lead to:
+1. Acceptance of highly uncertain prices
+2. Potential manipulation of protocol operations through unreliable price feeds
+3. Incorrect valuation of assets and collateral
+4. Unfair liquidations or prevented legitimate liquidations
+
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Add confidence interval validation in the `getThePrice` function:
+
+```solidity
+function getThePrice(address tokenAddress) public view returns (int) {
+ bytes32 _priceFeed = priceIdPerToken[tokenAddress];
+ require(_priceFeed != bytes32(0), "Price feed not set");
+ require(!isPaused, "Contract is paused");
+
+ PythStructs.Price memory priceData = pyth.getPriceNoOlderThan(
+ _priceFeed,
+ 600
+ );
+
+ require(isFeedAvailable[_priceFeed], "Price feed not available");
+ require(priceData.price > 0, "Invalid price");
+
+ // Add confidence interval validation
+ uint maxConfidenceInterval = priceData.price * MAX_CONFIDENCE_RATIO / 100;
+ require(
+ priceData.conf > 0 && priceData.conf <= maxConfidenceInterval,
+ "Price confidence interval too high"
+ );
+
+ return priceData.price;
+}
+```
+
+Consider:
+1. Adding a configurable `MAX_CONFIDENCE_RATIO` parameter (e.g., 2% = 200 basis points)
+2. Implementing different confidence thresholds for different assets or operations
+3. Adding events to track when prices are rejected due to high confidence intervals

+# NTF lockedDate should be checked when creating borrow offer
+
+### Summary
+
+The veNFT's lockedDate should be checked against the borrow duration before creating a borrow offer.
+
+### Root Cause
+
+Borrowers can create borrow offer by collateralizing their NFT receipts. The NFT receipts can be minted by depositing veNFTs, where these veNFTs are minted from locking underlying tokens. Locking usually persists a period time, and during which one can not withdraw their underlying tokens.
+Since the borrowers use receipt NFT as collaterall to borrow, if the locked end dates are not checked , they can potentially withdraw their underlying tokens right after the borrower offer created.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L103-L111
+### Internal pre-conditions

+
+### External pre-conditions

+_No response_
+
+### Attack Path
+
+Borrower locked his underlying tokens with a relatively short time duration to mint veNFT.
+Borrower deposit veNTF to Receipt-veNFT contract to mint receipt nft.
+Borrower creates borrowing offer against his receipt collateral.
+Borrower quickly withdraw his underlying tokens, after loan default, lenders will bear loss since there is no value in receipt.
+
+### Impact
+
+Lenders wiil suffer loss if the borrower can withdraw his underlying tokens right after borrowing offer creation.
+
+### PoC

+_No response_
+
+### Mitigation

+if be break down how connecter fee and interet amount is calculated we will get something like -
+
+```js
+ // uint interest = (anualInterest * activeTime) / 31536000;
+ // interest = ([(offer.principleAmount * offer.apr)] / 10000 * activeTime) / 31536000;
+ // interest = ([(offer.principleAmount * offer.apr)] * activeTime) / 315360000000;
+
+
+ // feeToConnector = ((sigma(lendAmountPerOrder[i])*((borrowInfo.duration * 4) / 86400)/10000)*1500)/10000
+ // feeToConnector = ((sigma(lendAmountPerOrder[i])*((borrowInfo.duration * 6000) / 86400)/10000))/10000
+ // feeToConnector = ((sigma(lendAmountPerOrder[i])*((borrowInfo.duration * 6) / 8640000000) 1440000000
+ // feeToConnector = ((sigma(lendAmountPerOrder[i])*((borrowInfo.duration / 1440000000
+```
+
+and if compare interest and feeToConnector, we will notice that feetoConnecter can be higher than the accumulated interest amount.
+
+So, if the creater of borrow order calls the `matchOffersV3()` then he will ends up getting higher amount than paying it as the debt.

+# DoS Attack due vulnerability in `matchOffersV3()`
+
+### Summary
+
+Given:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L319-L324
+
+A malicious actor can a craft arguments to the `matchOffersV3()` where the principle is arbitrarily large filled with duplicates of the `accepted principles` which would pass the check above since the require statement only checks if ` borrowInfo.acceptedPrinciples[indexForPrinciple_BorrowOrder[i]] == principles[i]`
+
+For instance a normal argument might have:
+- principles = [AERO, WETH]
+- indexForPrinciple_BorrowOrder[i] = [ 0, 1 ]
+- borrowInfo.acceptedPrinciples = [ AERO, WETH ];
+ This passes the check but a malicious argument can take this a step further to look something like:
+- principles = [ AERO, WETH, WETH, WETH, WETH, ... ] //keeps going arbitrarily
+- indexForPrinciple_BorrowOrder[i] = [ 0, 1, 1, 1, 1, ... ] //keeps going arbitrarily
+- borrowInfo.acceptedPrinciples = [ AERO, WETH ];
+
+The issue here is that the only length cap in the function is: https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L290
+
+which would have no effect what so ever in stopping the for loops which rely on `principles.length` (such as the one below) from running arbitrarily .
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L317-L368
+
+Which would most certainly cause a gas limit DoS.
+- This could also quite possibly lead to inaccurate calculations of `weightedAverageRatios` which could cause `borrowers` to borrow more than their collateral should permit them to.

+# Exploitable 2% Margin in `DebitaV3Aggregator.sol::matchOffersV3` Leads to Undercollateralized Loans.
+
+### Summary
+
+The 2% margin allowed in the `matchOffersV3` function of the `DebitaV3Aggregator.sol` contract permits `borrowers` to create undercollateralized loans, exposing lenders and the protocol to significant financial risk. `Attackers` can exploit this margin by consistently targeting the **upper bound** of the allowed ratio, systematically **undercollateralizing** loans. Over time, this can lead to **substantial cumulative losses** for `lenders` and threaten the protocol's financial stability.
+
+
+
+### Root Cause
+
+The improper handling of the collateralization ratio validation within the [`matchOffersV3`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274C5-L647C6) function, specifically the allowance of a ±2% margin between the `calculated weighted average ratio` and the ` borrower's ratio`:
+```solidity
+require(
+ weightedAverageRatio[i] >= ((ratiosForBorrower[i] * 9800) / 10000) &&
+ weightedAverageRatio[i] <= (ratiosForBorrower[i] * 10200) / 10000,
+ "Invalid ratio"
+);
+```
+The code permits the ` weightedAverageRatio[i]` to deviate by up to ±2% from the `ratiosForBorrower[i]` wich allows `borrowers` to target the **upper limit (102%)** to minimize the amount of collateral they need to provide for a given loan amount.
+And the most import point is that the protocol doesn't have safeguards to deny exploitation of consistently requesting loans using the maximum allowed ratio (102% of the calculated ratio).
+
+
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. `Attacker` recognizes that the protocol allows a 2% higher ratio in the validation check.
+2. Consistently requests loans using the maximum allowed ratio (102% of the calculated ratio).
+3. Repeats the process to accumulate undercollateralized positions.
+4. For each loan, provides 2% less collateral than what would be required at the precise ratio.
+
+### Impact
+
+ - Lenders may not recover the full amount lent due to insufficient collateral, leading to direct financial losses.
+ - The protocol's exposure to default risk increases with each undercollateralized loan.
+
+
+### PoC
+
+## Scenario
+
+- **Collateral Token (Token A):** Price \$100, 18 decimals.
+- **Principle Token (Token B):** Price \$1, 18 decimals.
+- **Borrower's Calculated Ratio:** 80 Token B per Token A (based on 80% LTV).
+- **Allowed Ratio with 2% Margin:** Up to 81.6 Token B per Token A.
+
+## Exploit Execution
+
+### Borrower Requests Loan
+
+- **Borrowing:** 816,000 Token B.
+
+### Calculates Required Collateral at Upper Bound Ratio
+
+$$
+\text{Collateral Required} = \frac{816,000}{81.6} = 10,000 \text{ Token A}
+$$
+
+### Collateral Required at Precise Ratio
+
+$$
+\text{Collateral Required} = \frac{816,000}{80} = 10,200 \text{ Token A}
+$$
+
+### Collateral Difference
+
+$$
+10\,200 - 10\,000 = 200\ \text{Token A saved (worth 20\,000)}
+$$
+
+### Repeats Process
+
+- **Creates multiple loans, each undercollateralized by 2%.**

+
+### Mitigation
+
+Look at how AAVE Implements varying collateralization ratios depending on asset volatility and employs strict liquidation mechanisms without margins for undercollateralization.

+# All lendOrder of the factory can be deleted using cancelOffer()
+
+### Summary
+
+All lendOrder of the factory can be deleted using cancelOffer() & addFunds()
+
+### Root Cause
+
+[addFunds()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L162C2-L176C6) doesn't check if order is active or not, allowing owner to add funds in the inactive lend order
+```solidity
+ function addFunds(uint amount) public nonReentrant {
+ require(
+ msg.sender == lendInformation.owner ||
+ IAggregator(aggregatorContract).isSenderALoan(msg.sender),
+ "Only owner or loan"
+ );
+ SafeERC20.safeTransferFrom(

+ msg.sender,
+ address(this),
+ amount
+ );
+ lendInformation.availableAmount += amount;
+ IDLOFactory(factoryContract).emitUpdate(address(this));
+ }
+```
+Also, owner can cancel the order using cancelOffer(), which deletes the lend order from the factory.
+
+The issue is, malicious user can take advantage of [cancelOffer()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L144) & [addFunds()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L162) to continously add funds & cancel the offer, which will decrease/remove all the lend orders from the [factory](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207C1-L220C6)

+# changeOwner() functions have no access control and does not transfer ownership to the new owner
+
+### Summary
+
+In DebitaV3Aggregator.sol, AuctionFactory.sol, buyOrderFactory.sol, a `changeOwner()` function is defined which is intended to change the owner field, which is a global storage variable.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682-L686
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L218-L222
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L186-L190
+
+There are 2 problems with this function
+- there is improper access control check on this function.
+- This function does not actually modify the owner storage variable to the owner argument provided by the caller.
+
+### Root Cause
+
+In the `changeOwner()` function, the `owner` argument has the same variable name as the `owner` state variable. This results in **variable shadowing**.
+
+- The check `require(msg.sender == owner, "Invalid address")` is validating that the msg.sender address is equal to the address passed as the argument, not the current owner (state variable).
+- `owner = owner` re-assigns parameter to itself. It does not actually modify the `owner` state variable
+
+### Internal pre-conditions
+
+- DebitaV3Aggregator.sol, AuctionFactory.sol, buyOrderFactory.sol contracts have been deployed
+- `changeOwner()` function is called within first 6 hours of contract deployment
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+- The address that deployed the contracts will be designated as the owner, and the ownership field will be immutable.
+- If the current owner's address is compromised or ownership needs to be transferred within six hours, there will be no mechanism available to facilitate such a transfer.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Use a different name for the argument passed in to the `changeOwner()` function.
+
+```solidity
+ function changeOwner(address newOwner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = newOwner;
+ }
+```

+# Lender calls `DebitaV3Loan::claimCollateralAsNFTLender` they will lose their collateral
+
+### Summary
+
+Due to incorrect checks in the contract, a lender can call `DebitaV3Loan::claimCollateralAsNFTLender` when a borrower has defaulted and the lender will be marked as `collateral paid` without transferring or crediting any collateral to the lender.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L340
+
+### Root Cause
+
+The root cause is the return value from the following function is ignored:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L361
+
+
+### Internal pre-conditions
+
+1. The borrower's collateral must be an NFT
+2. There must at least two lenders in the loan.
+3. The borrower defaults on its loan
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+Once the internal pre-conditions have been met the lender will call `DebitaV3Loan::claimCollateralAsNFTLender`. The lender will not receive the NFT since there are multiple lenders, but the lender will have their offer as `collateralClaimed == true` even though they have been credited/received nothing.
+
+### Impact
+
+The lender will not be able to claim the borrower's collateral after defaulting on the loan.
+
+### PoC
+
+One of the import locations might have to be fixed.

+# NFT will be stuck in BuyOrder.sol contract
+
+### Summary
+
+After the buyer calls the `createBuyOrder` function, the `BuyOrder.sol` will be created, and the tokens will be transferred to the contract. When the seller of the NFT calls `sellNFT` in `BuyOrder`, the NFT will be transferred to the contract instead of the buyer, effectively locking the NFT permanently.
+
+### Root Cause
+
+In [sellNFT](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrder.sol#L99-L103) function, the NFT will be locked in the `BuyOrder.sol` contract:
+```solidity
+IERC721(buyInformation.wantedToken).transferFrom(
+ msg.sender,
+--> address(this),
+ receiptID
+ );
+```
+
+### Internal pre-conditions
+
+1. The buyer creates an order for 1000 USDT in exchange for an NFT. [createBuyOrder]
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+2. The seller receives the 1000 USDT and transfers the NFT, which will then be locked in the contract. [sellNFT]
+
+### Impact
+

+# Miner can trick the borrower into accepting his last minute modified lend offer by manipulating block.timestamp.
+
+### Summary
+
+The [onlyAfterTimeOut](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L57) of `DLOImplementation` contract is expected to make sure that the lend offer hasn't been modified in the last minute before a borrower can accept it. A miner has the ability to pick block timestamp in a certain range(`parent timestamp < block.timestamp <= 15 min in the future.`). So after seeing that someone has sent a transaction accepting his lend offer a miner can trick the borrower into accepting his last minute modified lend offer by sending a new transaction to [DLOImplementation.updateLendOrder()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L195) that will benefit him and setting `block.timestamp` in a way that will break `onlyAfterTimeOut` check.
+
+### Root Cause
+
+The [DLOImplementation.updateLendOrder()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L195) function is as follows.
+```solidity

+ uint newApr,
+ uint newMaxDuration,
+ uint newMinDuration,
+ uint[] memory newLTVs,
+ uint[] memory newRatios
+ ) public onlyOwner {

+ LendInfo memory m_lendInformation = lendInformation;
+ require(

+ newLTVs.length == m_lendInformation.maxLTVs.length &&
+ newRatios.length ==
+ m_lendInformation.acceptedCollaterals.length,
+ "Invalid lengths"
+ );
+ lastUpdate = block.timestamp;
+ m_lendInformation.apr = newApr;
+ m_lendInformation.maxDuration = newMaxDuration;

+ m_lendInformation.maxRatio = newRatios;
+
+ // update to storage
+ lendInformation = m_lendInformation;
+ IDLOFactory(factoryContract).emitUpdate(address(this));
+ }
+```
+It keeps the`lastUpdate`check when someone modifies their lend offers.
+
+The [DLOImplementation.acceptLendingOffer()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L109) function is as follows:
+```solidity
+ // function to accept the lending offer
+ // only aggregator can call this function
+ function acceptLendingOffer(
+ uint amount
+ ) public onlyAggregator nonReentrant onlyAfterTimeOut {
+ LendInfo memory m_lendInformation = lendInformation;
+ uint previousAvailableAmount = m_lendInformation.availableAmount;
+ .....
+ .....
+```
+It uses an `onlyAfterTimeOut` modifier to perform a check.
+
+The [onlyAfterTimeOut](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L57) is as follows:
+```solidity
+ modifier onlyAfterTimeOut() {
+ require(
+ lastUpdate == 0 || (block.timestamp - lastUpdate) > 1 minutes,
+ "Offer has been updated in the last minute"
+ );
+ _;
+ }
+```
+This modifier is expected to make sure that the lend offer hasn't been modified in the last minute before a borrower can accept it.
+
+### Internal pre-conditions
+N/A
+
+### External pre-conditions
+Someone will have to send a transaction accepting the miner's lend offer by calling [DebitaV3Aggregator.matchOffersV3()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274).
+
+### Attack Path
+
+1. Miner created a lend offer.
+2. Miner sees someone has sent a transaction in the mempool accepting his lend offer.
+3. Miner send a new transaction to modify the lend offer terms that will benefit him by calling [DLOImplementation.updateLendOrder()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L195).
+4. Miner reorders the transaction list giving his `updateLendOrder` call higher priority.
+5. Miner sets `block.timestamp` to a value that will break `block.timestamp - lastUpdate > 1 minutes` check.
+
+### Impact
+Miner can trick the borrower into accepting his modified lend offer by manipulating `block.timestamp`.

+# When calculating the interest paid, precision loss can occur.
+
+### Summary
+
+When calculating interest, performing division first and then multiplication can lead to precision loss. Although the loss in interest might seem small initially, it can accumulate over time, resulting in a significant overall loss.
+
+### Root Cause
+
+Vulnerable code:

+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L734
+When annual interest and interest are calculated separately, it can lead to precision loss. Here's an example to explain this:
+- Suppose principleAmount = 1000, APR = 500 (5%), and activeTime = 60 days = 5184000 seconds.
+- The annualInterest is calculated as:
+ anualInterest = (offer.principleAmount * offer.apr) / 10000; = 50；
+- Then, the interest is calculated as:
+ interest = annualInterest × activeTime / 31536000≈8.22 However, due to precision loss, the result is rounded to interest = 8.
+
+If the principleAmount is much larger, the loss in interest will be even greater because the rounding error becomes more significant.

+# abi.encodePacked() allows hash collision, leading to miscalculation of funds and protocol malfunction
+
+### Summary
+
+If you use `keccak256(abi.encodePacked(a, b))` and both `a` and `b` are dynamic types, hash collisions can occur easily by moving parts of `a` into `b` and vice-versa.
+
+For example, `abi.encodePacked("a", "bc") == abi.encodePacked("ab", "c")`
+
+
+### Root Cause
+
+In `DebitaIncentives.sol`, `hashVariable(_principle, _epoch)` & `hashVariablesT(_principle, _epoch, _tokenToClaim)` take dynamic inputs, and derive the hash value by doing a packed encoding of these inputs.
+
+```solidity
+ function hashVariables(
+ address _principle,
+ uint _epoch
+ ) public pure returns (bytes32) {
+ return keccak256(abi.encodePacked(_principle, _epoch));
+ }
+ function hashVariablesT(
+ address _principle,
+ uint _epoch,
+ address _tokenToClaim
+ ) public pure returns (bytes32) {
+ return keccak256(abi.encodePacked(_principle, _epoch, _tokenToClaim));
+ }
+```
+
+Since there's is no padding in packed encoding, different sets of values when packed together could lead to the same hash value.
+
+Instances of occurence:
+- [L427](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L427)

+
+Hash collision could lead to fetching of a wrong value leading to miscalculations (a logical error)
+
+### PoC

+# Unusable Ownership Transfer Due to Parameter Shadowing Across Multiple Contracts.
+
+### Summary
+
+Three contracts (`DebitaV3Aggregator.sol`, `AuctionFactory.sol`, and `BuyOrderFactory.sol`) contain a `changeOwner` function that fails to update the state variable `owner` due to parameter shadowing. This issue renders the ownership transfer mechanism ineffective, potentially allowing the existing owner to lose control over the contract if the vulnerability is exploited.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682
+
+### Affected Code
+**File**: `DebitaV3Aggregator.sol`
+**Function**: `changeOwner`
+**Line**: 707
+
+### Root Cause
+
+The function parameter `owner` in the `changeOwner` function shadows the contract's state variable `owner`. This results in the assignment `owner = owner` updating the parameter instead of the state variable, leaving the ownership state unchanged.
+
+### Affected Code Pattern:
+```javascript
+function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner; // Parameter shadowing prevents state update
+}
+```
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol
+
+### Internal pre-conditions
+
+# INTERNAL PRECONDITION
+1. The contract's `changeOwner` function is callable.
+2. The function relies on the `owner` state variable for authorization and state update.
+3. The state variable `owner` remains unaltered despite the function being called.
+
+
+### External pre-conditions
+
+1. The contract has no safeguards (e.g., naming conventions or clear parameter differentiation) to prevent parameter shadowing.
+
+### Attack Path
+
+# ATTACK PATH
+1. The Owner calls the `changeOwner` function with a valid address, intending to transfer ownership.
+2. The parameter `owner` shadows the state variable, so the assignment does not update the state variable.
+3. The existing owner retains ownership, or the function fails silently without achieving the intended effect.
+
+### Impact
+
+the failure to transfer ownership effectively locks the contract's governance to the current owner.
+This can lead to an operational deadlock, to a certain address or exploitation if the current owner loses access to their private key or malicious actors exploit the ineffective check to maintain control over the contract.
+
+### PoC
+
+```solidity
+function testChangeOwner() public {
+ address thief = makeAddr("thief");
+ vm.startPrank(thief);
+ DebitaV3AggregatorContract.changeOwner(thief);
+ vm.stopPrank();
+ console.log("Address of the thief", thief);
+ console.log("Address of the contract owner", DebitaV3AggregatorContract.returnOwner());
+}
+```
+
+
+### Mitigation
+
+1. **Avoid Parameter Shadowing**:
+ - Use a different name for the function parameter (e.g., `newOwner`) to distinguish it from the state variable.
+ ```solidity
+ function changeOwner(address newOwner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = newOwner;
+ }

+# Some Pinciple/Collateral token pair will not work due to rounding error in the DebitaV3Aggregator.matchOffersV3() function.
+
+### Summary
+
+In the DebitaV3Aggregator.matchOffersV3() function, there is a calculation of ratio of principle and collateral token.
+
+However, in case of which the price of Collateral token is very small compared to the price of Principle token, borrower and lender's offer can't be matched because of rounding error.
+
+### Root Cause
+
+In the [DebitaV3Aggregator.sol:350](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L350-L361) function, there is a calculation of the ratio of 'priceCollateral_BorrowOrder' and 'pricePrinciple'.
+
+To avoid floating, we multiply by 10^8 to get extra 8 decimals. However, floating can be occured when price of Collateral is too small compared to the price of Pinciple. For example, let's assume collateral token is BTC which is high price and principle token is Pepe which is low price. The ratio is calculated as following at current time:
+
+priceCollateral_BorrowOrder * 10 ** 8 / pricePrinciple = 0.00002 * 10 ** 8 / 98000 = 0.

+# `incetivizePair` function is not working as intended
+
+### Summary
+
+The `DebitaIncentives::incentivizePair` function fails to properly update the `bribeCountPerPrincipleOnEpoch` mapping, resulting in incorrect incentive data per principle. This issue may prevent users from accurately claiming their incentives due to misrepresented information.
+
+### Root Cause
+
+ If a bribe token is already added once for the epoch, the function will not enter in the if statement no matter if the principle is different, then on line 264 instead of increasing the amount of bribe tokens added for the current principle, the `incentivizeToken` is passed as argument to the `bribeCountPerPrincipleOnEpoch` mapping.
+
+The issue lies in the `if` statement at [DebitaIncentives.sol:257](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L257). If a bribe token has already been added for an epoch, the function skips updating the data structure even if the principle is different. Additionally, on `line 264`, the `bribeCountPerPrincipleOnEpoch` mapping incorrectly increments using the incentivizeToken instead of the current principle.
+
+### Impact
+
+Incorrect updates to `bribeCountPerPrincipleOnEpoch` cause the `DebitaIncentives::getBribesPerEpoch` function to return inaccurate results. This could mislead users about claimable incentives, preventing them from claiming their rightful rewards.
+
+### PoC
+
+Add this test to Debita-V3-Contracts/test/fork/Incentives/MultipleLoansDuringIncentives.t.sol
+```solidity
+function testIncentivizeMultipleBribesForTheSamePrinciple() public {
+ incentivize(AERO, AERO, USDC, false, 1e18, 2);
+ incentivize(AERO, AERO, wETH, false, 1e18, 2);
+ uint256 bribesLength = incentivesContract.getBribesPerEpoch(2, 0, 10)[0].bribeToken.length;
+ address principle = incentivesContract.getBribesPerEpoch(2, 0, 10)[0].principle;
+ console.log("bribesLength: ", bribesLength);
+ console.log("principle: ", principle);
+ console.log("bribes ", incentivesContract.bribeCountPerPrincipleOnEpoch(2, principle));
+ }
+```
+
+### Mitigation
+
+The `hasBeenIndexedBribe` mapping should include the principle as an additional parameter since an incentive can apply to multiple principles. Additionally, on [line 264](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L264C17-L264C74), the `bribeCountPerPrincipleOnEpoch` mapping should increment using the principle rather than the incentivizeToken:
+
+```diff
+- bribeCountPerPrincipleOnEpoch[epoch][incentivizeToken]++;
++ bribeCountPerPrincipleOnEpoch[epoch][principles[i]]++;

+# Missing aggregatorContract validation allows uninitialized state in `DebitaBorrowOffer-Factory` and `DebitaLendOfferFactory`
+
+### Summary
+
+The missing validation check for `aggregatorContract` will cause a functionality breakdown for borrowers and lenders as uninitialized instances default to address(0), which blocks operations restricted by the onlyAggregator modifier.
+
+### Root Cause
+
+In [DebitaBorrowOffer-Factory.sol](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L75-L123) and
+[DebitaLendOfferFactory.sol](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L124-L175), the `aggregatorContract` is declared but not validated before being used to initialize new instances of `DebitaBorrowOffer-Implementation` or `DebitaLendOffer-Implementation`. As a result, it defaults to address(0) if not explicitly set.
+
+### Internal pre-conditions
+
+1. The `aggregatorContract` variable in the factory contracts must remain unset `(address(0))` before calling the `createBorrowOrder` or `createLendOrder` functions.
+2. The `createBorrowOrder` or `createLendOrder` functions must be called without setting the `aggregatorContract`.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+The borrowers and lenders are unable to utilize key functions restricted by the `onlyAggregator` modifier. This renders the system inoperable for affected operations, disrupting workflow and usability
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Enforce validation of `aggregatorContract` before initializing new instances by adding a require statement in the `createBorrowOrder` and `createLendOrder` functions:
+
+```solidity
+require(aggregatorContract != address(0), "Aggregator contract not set");
+```
+This ensures that `aggregatorContract` is explicitly assigned a valid address before being used to initialize implementation contracts.

+# Owner Shadowing Vulnerability
+
+### Summary
+
+The `changeOwner` function in the` DebitaV3Aggregator.sol` contract contains a vulnerability caused by shadowing the state variable `owne`r with a function parameter of the same name. This results in the function modifying only the local variable `owner` instead of the state variable, leaving the actual ownership unchanged. Additionally, the function contains insufficient access control checks, as the logic allows anyone to call it after six hours of deployment due to the flawed ownership validation.
+
+### Root Cause
+
+The function parameter `owner` in [DebitaV3Aggregator:682-686](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682-L686) has the same name as the state variable owner, causing the local variable to be modified instead of the state variable.

+ DebitaV3AggregatorContract.changeOwner(newOwner);
+ }
+ ```
+
+### Mitigation
+
+ **Avoid Variable Shadowing**:
+ - Use distinct names for function parameters and state variables to prevent shadowing. For example:
+```javascript
+function changeOwner(address _owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = _owner;

+# TarotPriceOracle: uses reserve0CumulativeLast instead of price0CumulativeLast
+
+### Summary
+
+The TarotPriceOracle is used to calculate Time-Weighted Average Prices (TWAP) for token pairs in Uniswap V2 pools.
+However, in the `getPriceCumulativeCurrent()` function, it uses an incorrect function call to get the value for `priceCumulative`.
+
+
+
+
+
+### Root Cause
+
+In MixOracle.sol, `setAttachedTarotPriceOracle()`:
+- A new TarotPriceOracle contract is deployed via a proxy.
+- Subsequently the`initialize()` function is invoked, with the `uniswapV2pair` address provided as an argment.
+
+In TarolPriceOracle.sol, the `initialize()` function:
+- retrives the `priceCurrentCumulative` value is via the `getPriceCumulativeCurrent()` function
+- In `getPriceCumulativeCurrent()`, the `priceCumulative` is retrived via `priceCumulative = IUniswapV2Pair(uniswapV2Pair).reserve0CumulativeLast()`
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/MixOracle/TarotOracle/TarotPriceOracle.sol#L36-L37
+
+However, there is **no such function in uniswap v2 interface**. The correct function should be is `price0CumulativeLast()`.
+
+The uniswap v2 interface is provided here: https://github.com/Uniswap/v2-core/blob/master/contracts/UniswapV2Pair.sol.
+
+The MixOracle and TarotPriceOracle contracts are designed to work with uniswapV2pairs. This vulnerability severely impacts the core functionality of these contracts.
+
+### Internal pre-conditions
+
+- Multisig calls `setAttachedTarotPriceOracle(address uniswapV2Pair)` on MixOracle.sol providing a valid uniswapv2 pair.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+The `setAttachedTarotPriceOracle(address uniswapV2pair)` would revert, which restricts the functionality of MixOracle.sol. The `getTokenPrice(address uniswapV2pair)` function would not fail, as the TarotPriceOracle contract would not be able to register the uniswapv2pair.

+# insufficient input validation allows other lend order in `DLOFactory` to be deleted
+
+### Summary
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207-L220
+
+The deleteOrder function in the DLOFactory contract lacks input validation to ensure the deleted order has not already been removed. While this issue does not manifest in other factory contracts where the delete function is restricted to a single call, it becomes a significant vulnerability in conjunction with the DLOImplementation contract.
+
+In DLOImplementation, users can repeatedly invoke addFunds and cancelOffer, which indirectly triggers the deletion of orders in the factory. This allows malicious or unintended repeated deletions, potentially disrupting the integrity of the factory's state.
+

+# Unused variable `implementationContract` in `DebitaBorrowOffer-Factory.sol`
+
+### Summary
+
+In the `DebitaBorrowOffer-Factory.sol` contract contains an `implementationContract` variable that is initialized
+in the constructor but never used elsewhere in the contract. This unused variable suggests a deviation form the intended
+use of the proxy pattern for deploying the `DebitaBorrowOffer-Implementation.sol` contract. The root cause appears to be the
+omission of the proxy deployment mechanism, leading to issues with the contract`s upgradeability.
+
+### Root Cause
+
+In the [DebitaBorrowOffer-Factory.sol:48](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L48) the variable is set in the constructor but never used elsewhere in the contract.

+# Missing Circuit Breaker Price Cap Detection in DebitaChainlink Oracle
+
+### Summary
+
+Lack of validation for Chainlink's circuit breaker price caps in DebitaChainlink will cause incorrect price reporting for protocol users as malicious actors can exploit the capped prices during extreme market conditions.
+
+### Root Cause
+
+In DebitaChainlink.sol:getThePrice() at https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L30, the function lacks validation checks for Chainlink's circuit breaker price caps:

+
+### External pre-conditions

+
+### Attack Path
+
+1. Attacker monitors Chainlink feeds for prices approaching circuit breaker thresholds

+3. Attacker calls protocols/functions that rely on DebitaChainlink oracle
+4. DebitaChainlink returns capped price instead of actual market price
+5. Attacker executes trades/operations using artificial price, potentially:
+
+Taking undercollateralized loans if actual price is lower than cap
+Liquidating healthy positions if actual price is higher than floor
+Conducting other price-dependent operations at incorrect valuations

+# Owner unable to transfer ownership due to incorrect variable assignment in `changeOwner` function
+
+### Summary
+
+The incorrect variable assignment in the `changeOwner` function will cause an inability to change the owner of the contract. This happens because the function assigns the parameter to itself instead of updating the state variable, preventing the owner from transferring ownership within the allowed time frame.
+
+### Root Cause
+
+In the `changeOwner` function at the following locations:
+[`DebitaV3Aggregator.sol:682`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682)
+[`AuctionFactory.sol:218`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L218)
+[`buyOrderFactory.sol:186`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L186)
+
+the parameter `owner` shadows the state variable `owner`. The assignment `owner = owner; `incorrectly assigns the parameter to itself, leaving the state variable `owner` unchanged.
+
+### Internal pre-conditions
+
+The current owner calls `changeOwner` with the intention to transfer ownership to a new address.
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. The owner attempts to transfer ownership by calling `changeOwner` with the new owner's address.
+2. Due to the incorrect assignment (`owner = owner;`), the state variable `owner` remains the same.
+3. After 6 hours from deployment, the owner cannot attempt to change ownership again due to the time restriction which makes the issue even more severe.
+
+### Impact
+
+The owner is unable to transfer ownership of the contract, potentially locking administrative control permanently. This prevents any future administrative updates, upgrades, or the ability to relinquish control, which could have severe implications for contract maintenance and security.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Rename the function parameter to `newOwner` and update the assignment to correctly reflect the intended behavior:
+```solidity
+function changeOwner(address newOwner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = newOwner;

+# Chainlink's `latestRoundData` might return stale or incorrect results
+
+### Summary
+
+The protocol relies on Chainlink’s latestRoundData() in DebitaChainlink.sol::getThePrice() to fetch price data without completely validating its freshness. Although the quoteAnswer is checked to be greater than zero, however this alone is not sufficient. This incomplete validation could have the protocol produce incorrect values for very important functions in different places across the system especially within the DebitaV3Aggregator.sol::matchOffer() where the `getPriceFrom()` function which is the oracle implementation is called multiple times
+
+### Root Cause
+
+the getThePrice function https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L30-L47 lacks complete validation in these variables coming from latestRoundData() - roundId, updateTime and answeredInRound

+# Stuck Incentives Due to Fee-on-Transfer (FOT) Token Discrepancy
+
+### Summary
+
+There’s a problem in the `DebitaIncentives` smart contract when Fee-on-Transfer (FOT) tokens are used for incentivization.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L225
+
+ Here’s what happens:
+- When FOT tokens are added as incentives, the contract records the full amount (e.g., 10,000 tokens). However, due to transfer fees, it only receives a smaller amount (e.g., 9,800 tokens).
+- When users start claiming their share, the first few users get the rewards as if the full 10,000 tokens are available.
+- As more users claim, the contract eventually runs out of tokens before everyone is paid.
+- This causes the transaction for the last few claimants to fail, leaving the remaining tokens stuck in the contract with no way to recover them.
+
+- The attacker secures an unfairly large share of rewards before others.
+- The attacker ensures they claim an inflated share of the rewards, leaving insufficient tokens for later claimants.
+- Other participants face failed claims and lose their incentives.
+- Remaining tokens become permanently inaccessible, harming the protocol’s credibility and user trust.
+
+### Root Cause
+
+When someone adds tokens as incentives through the incentivizePair function, the contract records the full amount provided in the function call, regardless of how many tokens are actually transferred.
+Example:
+- A user incentivizes 10,000 tokens.
+- The FOT token has a 2% transfer fee.
+- The contract records 10,000 tokens as available for incentives, but only 9,800 tokens are actually received.
+
+```solidity
+IERC20(incentivizeToken).transferFrom(msg.sender, address(this), amount);
+lentIncentivesPerTokenPerEpoch[principle][hashVariables(incentivizeToken, epoch)] += amount;
+```
+Here, the contract records amount as the incentive balance but doesn’t check how many tokens were actually transferred.
+
+Distribution Logic Assumes Full Balance:
+
+- The contract calculates rewards for each user based on the recorded incentive balance (e.g., 10,000 tokens in this case), not the actual available balance (9,800 tokens).
+- Early claimants receive rewards as if the full balance exists, which depletes the actual tokens in the contract faster than expected.
+Example:
+
+
+ If there are 10 eligible users, each supposed to receive 1,000 tokens
+ The first 8 users successfully claim 8,000 tokens in total.
+ Now, only 1,800 tokens remain in the contract.
+ When the remaining users (e.g., the last 2 claimants) attempt to claim their share (1,000 tokens each), the contract doesn’t have enough tokens to fulfill the transaction.
+ The IERC20(token).transfer call fails because the contract has insufficient tokens, reverting the entire transaction.
+
+Stuck Tokens after all the claims:
+
+ • After the failed transactions, any remaining tokens (e.g., 800 tokens) are left stuck in the contract because:
+ • The claiming process doesn’t allow partial payouts.
+ • The incentives were calculated based on incorrect balances, leaving no mechanism to reclaim or redistribute the leftover tokens.
+
+This assumes the full recorded balance is available for distribution.
+If the actual balance is lower, later transactions will fail.
+```solidity
+uint amountToClaim = (lentIncentive * porcentageLent) / 10000;
+IERC20(token).transfer(msg.sender, amountToClaim);
+```
+

+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+The attcker can monitor if FOT tokens are used as incentives and if is a borrower/lender he can claim the incentives as quickly as possible and the legitimate users of the protocol will not receive their fair amount of share
+Let’s say 10,000 FOT tokens are added as incentives. The FOT fee is 2%, so the contract only receives 9,800 tokens.
+However, the contract still thinks 10,000 tokens are available for rewards.
+
+Now Users Claim Their Incentives:
+ • There are 10 eligible users, each supposed to get 1,000 tokens.
+ • The first 8 users claim their share, withdrawing 1,000 tokens each.
+ • After 8 claims:
+
+9,800 - (1,000 * 8) = 800
+
+The Problem for the Last 2 Users:
+ • When the last 2 users try to claim their 1,000 tokens each, the transaction fails because there’s only 800 tokens left.
+ • Those 800 tokens are now stuck in the contract, and there’s no way to get them out.
+
+
+### Impact
+
+1. Unfair Distribution:
+ • Early claimants receive a higher share than they should, while late claimants get nothing.
+2. Stuck Tokens:
+ • Tokens left in the contract after failed claims are permanently inaccessible.
+3. Exploitation Risk:
+ • A malicious actor could intentionally use FOT tokens to drain rewards for themselves while leaving nothing for others.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+1. Record Actual Tokens Received:
+ • When someone adds incentives, calculate how many tokens were actually received:
+```solidity
+uint balanceBefore = IERC20(token).balanceOf(address(this));
+IERC20(token).transferFrom(msg.sender, address(this), amount);
+uint balanceAfter = IERC20(token).balanceOf(address(this));
+uint netReceived = balanceAfter - balanceBefore;
+```
+2. Handle Partial Claims:
+ • If there aren’t enough tokens to fulfill a user’s full claim, give them as much as the contract can:
+```solidity
+uint availableBalance = IERC20(token).balanceOf(address(this));
+uint claimableAmount = (amountToClaim <= availableBalance) ? amountToClaim : availableBalance;
+IERC20(token).transfer(msg.sender, claimableAmount);
+```

+
+### Summary
+
+The DebitaChainlink contract does not check if the chainlink orice feed is stale
+
+### Root Cause
+
+In `DebitaChainlink::getThePrice` there is no check for the staleness of the price feed. All chainlink price feeds have a heartbeat(a window of time during which the price feed is considered valid) , prices older than the heartbeat are considered stale and should not be trusted.

+# Any update/cancel function in DBO and DLO can be frontrunned
+
+### Summary
+
+Let's look at the functions
+- [`DBO::cancelOffer`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Implementation.sol#L188).

+
+Each of these functions modifies the borrowOffer, lendOrder parameters.
+However, a call to each of these functions can be frontrun by any user by calling `matchOffersV3` which will use the old function parameters.
+
+Given that one of the networks on which the contract will be deployed is Fantom, which is an L1 blockchain, the problem of fronrunning should be taken seriously.
+
+
+### Root Cause
+
+Changing important borrowORder, lendOrder parameters should be done in two stages to protect the call of these functions from frontrunning
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Borrower wants to change maxApr for borrowOffer
+2. Anyone frontrun this transaction and match borrowOffer with old maxApr
+
+### Impact
+
+The lack of any protection against frontrunning, especially on L1 networks, allows attackers to execute transactions at amounts more favourable to them, thereby disrupting the honest work of both borrowers and lenders
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Implement a two-stage mechanism. The first call users pause the entire contract. The second call changes the parameters and then unpause the contract.

+# DebitaChainlink does not check for min/max prices during flash crashes
+
+### Summary
+
+Chainlink price feeds have in-built minimum & maximum prices they will return; if during a flash crash, bridge compromise, or depegging event, an asset’s value falls below the price feed’s minimum price, the oracle price feed will continue to report the (now incorrect) minimum price.
+
+### Root Cause
+
+In `DebitaChainlink::getThePrice` there is no check if the price returned by the oracle is at the minimum or maximum price boundaries indicating a price crash or depeg event
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L30-L47
+
+ As a result
+
+An attacker could:
+
+- buy that asset using a decentralized exchange at the very low price,
+- deposit the asset into a Lending / Borrowing platform using Chainlink’s price feeds,
+- borrow against that asset at the minimum price Chainlink’s price feed returns, even though the actual price is far lower.
+This attack would let the attacker drain value from [Lending / Borrowing platforms](https://rekt.news/venus-blizz-rekt/). To help mitigate such an attack on-chain, smart contracts could check that minAnswer < receivedAnswer < maxAnswer.

+# Lack of upgradeability in factories and aggregator contracts and improper initialization of instance in `createBorrowOrder`
+
+### Summary
+
+Factories and aggregator contracts rely on proxies for deploying `borrow`, `lend`, `buyOrder `and `loan` instances. However, the implementation contracts cannot be upgraded, defeating the primary purpose of this setup.
+
+**The sponsor has confirmed in private thread that this is an issue for the protocol.**
+
+Additionally, in the `createBorrowOrder function, the `DBOImplementation` is directly instantiated without using a proxy, which does not follow the consistent architectural design of the protocol.
+
+### Root Cause
+
+The factories and aggregator contracts do not provide a mechanism to update the implementation contracts. This means any future improvements or fixes **on the implementation** require deploying all new factories which is against the protocol's factories setup purpose of managing any upgrade directly from the factory.
+Here is the list of the instances where this is an issue:
+- [DebitaBorrowOffer-Factory](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L53)
+- [DebitaLendOfferFactory](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L99)
+- [DebitaV3Aggregator](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L232)
+- [buyOrderFactory](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L58)
+
+In the `createBorrowOrder` function of `DebitaBorrowOffer-Factory`, the `DBOImplementation` is directly instantiated directly [without using the proxy](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L106).
+
+### Impact
+
+The lack of upgradeability in factories and aggregator contracts will result in the protocol being unable to freely upgrade the implementations and needing to redeploy most contracts again.
+The upgrade functionality in the factories which is expected by users, is not working as expected.
+
+### Mitigation
+
+- Add a function in the factories and aggregator contracts to update the implementationContract address:
+```js
+function updateImplementation(address newImplementation) external onlyOwner{
+ implementationContract = newImplementation;
+}
+```
+- Replace the direct instantiation of `DBOImplementation` in `createBorrowOrder` with the proxy pattern:
+```js
+DebitaProxyContract proxy = new DebitaProxyContract(implementationContract);
+DBOImplementation borrowOffer = DBOImplementation(address(proxy));
+```

+# Setting wrong fee address could lead to loss of fees
+
+### Summary
+
+In `AuctionFactory.sol`, the owner can change/set the `feeAddress`, address to which the fees is sent.
+
+There is no check for zero addresses or 2 step transfer mechanism to prevent setting a wrong address by mistake.
+
+This could lead to a loss of funds as the fees collected could be burned or sent to a wrong address.
+
+### Root Cause
+
+The owner can set the `feeAddress` by calling `setFeeAddress(address)` in `AuctionFactory.sol`. In [line 215](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L215), the fee address is simply set to the address passed to the function without any checks.

+```solidity
+ function setFeeAddress(address _feeAddress) public onlyOwner {

+
+If it is some other address, the fee would be lost to an unintended recipient.
+
+### PoC
+

+
+### Mitigation

+- Add a zero address check
+- Add a two step verification mechanism (something similar to OpenZeppelin's [Ownable2Step](https://docs.openzeppelin.com/contracts/5.x/api/access#Ownable2Step))
+
+Note that a two step verification mechanism would come with it's own overhead. The decision to implement it should be taken by considering the relevant technical & financial tradeoffs.

+# Malicious lendOrder can delete all orders
+
+### Summary
+
+`DLOFactory::deleteOrder` can be called idefinitely by a lendOrder to delete all orders
+
+
+### Root Cause
+
+In [`DLOFactory::deleteOrder`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207-L220) the function can be called by a lendOrder to delete itself, However, a malicious lendOrder can also delete other orders by calling the same function over and over again. This is possible due tot the following reasons
+
+- LendOrders are zero indexed (i.e the first lendOrder is at `allActiveLendOrders[0]` & `LendOrderIndex[firstOrder] = 0`) so setting the index to 0 (as is done in the `deleteOrder` function) does not actually delete the order
+- There's no check if the order is already deleted
+- The lendOrder can call `DLOFactory::deleteOrder` as long as `availableAmount > 0` and because the lendOrder owner can always increase the availabe amount via the `addFunds` function , `deleteOrder` can be called indefinitely
+
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Attacker creates a lendOrder bt calling the lendOrder factory `createLendOrder` function with a `startLendingAmount` of 1 wei
+2. Attacker calls `DLOImplementation::cancelOffer` -> `DLOFactory::deleteOrder` to delete the order
+- The `LendOrderIndex[lendOrder]` is set to 0
+- The last order (at `index == activeOrdersCount - 1`) is moved to the previous index of the deleted order
+- The `activeOrdersCount` is decreased by 1
+3. The attacker calls `DLOImplementation::addFunds` to increase the `availableAmount` of the deleted order
+4. Repeats 2 - 3 indefinitely, but each time the last order is now moved to `index == 0`(which is the index of the deleted order) and the `activeOrdersCount` is decreased
+
+
+### Impact
+
+High - Attacker can delete all orders
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+1. LendOrder indexing should begin from 1
+2. Check if lendOrder is already deleted (i.e. if its index is 0) before deleting it

+# An attacker can bypass the maxApr limit to gain higher profits
+
+### Summary
+
+The calculation of APR is performed using weighted averaging and is rounded down. This can result in a situation where the actual APR exceeds maxApr, but due to the rounding down, the computed value becomes 0. An attacker can exploit this by providing a very high weight value as the denominator for (lendInfo.apr * lendAmountPerOrder[i]) / amountPerPrinciple[principleIndex]. Subsequently, the attacker can increase the APR and set lendAmountPerOrder to a very small value. By doing so, the attacker can manipulate a significant portion of a borrowInfo's borrowAmount to match at an APR exceeding maxApr, causing losses to the borrower.
+
+### Root Cause
+
+The issue arises in the following code:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L490-L491

+Here, the APR is calculated using weights, and the orders at the front affect the subsequent calculations. The larger the value of the earlier orders, the more the later values are impacted by precision issues.
+
+### Internal pre-conditions
+
+1. The attacker must provide an array where the first value is significantly large to cause greater precision loss in the subsequent weighted calculations.
+
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. The attacker calls matchOffersV3 to initiate order matching and sets the APR of the first lend order to borrowInfo.maxApr. For the subsequent lend orders, they can set the APR very high but keep the lendAmountPerOrder very small, causing the calculated value to be 0.
+
+### Impact
+
+The borrower's APR can exceed the maxApr limit and be set to an arbitrary value.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Instead of using a weighted average APR, it is recommended to use a simple average APR or perform a check on each individual APR.

+# DebitaV3Aggregator::matchOffersV3 assumes principle and collateral price feeds have the same decimals
+
+### Summary
+
+`DebitaV3Aggregator::matchOffersV3` assumes that principle and collateral price feeds have the same decimals, this is clearly not the case as Debita is designed to work with different types of oracles eg. Chainlink , pyth and Mix(twap + pyth)
+
+
+### Root Cause
+
+In `DebitaV3Aggregator::matchOffersV3` ln 350 expects the principle and collateral price feeds to have the same decimals and ` ValuePrincipleFullLTVPerCollateral` to be in 8 decimals
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L350-L362
+
+```solidity
+uint ValuePrincipleFullLTVPerCollateral = (priceCollateral_BorrowOrder * 10 ** 8) / pricePrinciple
+```
+
+However because the protocol is designed to work with different types of oracles eg. Chainlink , pyth and Mix(twap + pyth), the principle and collateral price feeds may have different decimals and `ValuePrincipleFullLTVPerCollateral` will not be in 8 decimals.
+
+It is important to note that `ValuePrincipleFullLTVPerCollateral` is used to determine the ltv ratio as seen here
+```solidity
+ // take 100% of the LTV and multiply by the LTV of the principle
+ uint value = (ValuePrincipleFullLTVPerCollateral *
+ borrowInfo.LTVs[indexForPrinciple_BorrowOrder[i]]) / 10000;
+
+ /**
+ get the ratio for the amount of principle the borrower wants to borrow
+ fix the 8 decimals and get it on the principle decimals
+ */
+ uint ratio = (value * (10 ** principleDecimals)) / (10 ** 8);
+ ratiosForBorrower[i] = ratio;
+```
+which is supposed to be in principle token decimals and is used to calculate the amount of collateral used for the loan

+# Variable Shadowing in the `owner` Variable
+
+### Summary
+
+The owner variable in the Aggregator and Factory smart contracts suffers from variable shadowing, which occurs when a local or function-scoped variable unintentionally overrides a state variable of the same name. This can lead to confusion in code logic and unintended behavior where the ownership of the contract can never be changed because the new changes will only update the local variable and not the state variable itself. All the contracts with `changeOwner` function are affected by this issue
+
+### Root Cause
+
+The owner variable is defined as a state variable in multiple smart contracts, including the `DebitaV3Aggreagtor`, `AuctionFactory`, `buyOrderFactory` contracts have the similar code:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L682
+
+```solidity
+function changeOwner(address owner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = owner;
+}
+```
+In this code, the local parameter owner shadows the state variable owner. Instead of updating the contract’s state variable, the function inadvertently assigns the parameter to itself, effectively doing nothing.
+
+1. Pass newOwnerAddress as the owner parameter.
+2. Evaluate the require(msg.sender == owner, "Only owner"); condition using the state variable owner.
+3. Reassign the local variable owner to itself (owner = owner), leaving the state variable owner untouched.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+When protocol owners attempt to use this function to transfer ownership and it fails, they may falsely believe the system is secure when, in reality, the code’s intent is simply broken.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Rename Local Variables and Use distinct names for function parameters to avoid shadowing the state variable. For example:
+```solidity
+function changeOwner(address newOwner) public {
+ require(msg.sender == owner, "Only owner");
+ require(deployedTime + 6 hours > block.timestamp, "6 hours passed");
+ owner = newOwner;
+}
+```

+# potential DOS attack in the `DebitaIncentives.sol::incentivizePair` Loop Over Principles.
+
+## **SUMMARY**
+The `DebitaIncentives.sol::incentivizePair` function has a for loops that process arrays (`principles``). This design leads to potential DOS gas exhaustion when:
+1. The size of `principles` is very large (no explicit limit is enforced).
+2. Multiple calculations and storage writes, such as weighted averages and collateral updates, exacerbate gas usage.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L240
+---
+
+## **ROOT CAUSE**
+The for loop iteration over large array (`principles`) combined with gas-heavy external calls, validations, and updates, makes the function prone to running out of gas as input sizes grow. No upper limit on `principles.length` increases the risk, . as at today the current max limit per function is 30 Million.
+
+---
+
+## **Internal Precondition**
+- The `principles` array is very large.
+- Storage mappings like `principlesIncentivizedPerEpoch` and `SpecificBribePerPrincipleOnEpoch` require frequent updates.
+- Gas-intensive external calls are made for each element of `lendOrders`.
+
+---
+
+## **External Precondition**
+- An attacker submits an array with an excessively large `principles` length, exploiting the lack of an explicit upper limit.
+- Heavy lending and borrowing activity.
+
+---
+
+## **ATTACK PATH**
+1. An attacker supplies a large `principles` array.
+2. The contract performs an unchecked iterations and repeated external calls, exhausting available gas.
+3. This causes the transaction to fail, potentially denying service to legitimate users.
+
+---
+
+## **POC**
+
+```solidity
+
+function incentivize2(
+ uint numPrinciples, // Number of principles

+ // Create arrays dynamically

+
+# Incorrect Deletion Patterns Lead to Data Corruption and Potential Exploitation Across Multiple Contracts
+
+### Summary
+
+The Debita v3 protocol exhibits improper deletion patterns in several factory contracts. When removing the last element from arrays tracking active entities (such as auctions, buy orders, borrow offers, and lend offers), the contracts incorrectly update internal mappings. This mismanagement results in assigning valid indices to `address(0)`, corrupting the internal state. Consequently, when new entities are added, index duplication occurs, leading to inconsistencies between arrays and mappings. This data corruption can cause severe operational failures, inaccurate data representation on the frontend, and potential security vulnerabilities due to the inconsistent state.
+
+### Root Cause
+
+In multiple factory contracts, the deletion functions for various entities incorrectly handle the removal of the last element in their respective arrays. When the last element is deleted:
+- The function attempts to swap it with the last element (which is itself) and sets the last array slot to `address(0)`.
+- The mapping that tracks indices is then updated, inadvertently assigning a valid index to `address(0)`.
+- This results in `address(0)` holding a valid index in the mapping, corrupting the data structure.
+
+This incorrect deletion pattern is present in the following contracts:
+
+- [`AuctionFactory`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/AuctionFactory.sol#L145)
+- [`buyOrderFactory`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/buyOrders/buyOrderFactory.sol#L127)
+- [`DebitaBorrowOfferFactory`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaBorrowOffer-Factory.sol#L162)
+- [`DebitaLendOfferFactory`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOfferFactory.sol#L207)

+- An entity (e.g., an auction) calls its deletion function to remove itself from the active list.
+- Being the last element, its index equals the count minus one.
+
+2. Incorrect Mapping Update:
+
+- The function assigns address(0) to the array at the deleted index.
+- The index mapping is updated, assigning the deleted index to address(0).
+
+3. Corruption of Mappings:
+
+- address(0) now holds a valid index in the mapping.
+- When a new entity is added, it may receive the same index, causing duplication.
+
+4. Resulting Issues:
+- Functions that rely on accurate mappings may fail or produce incorrect results.
+- Frontend displays incorrect data or fails to display new entities.
+- An attacker could exploit this inconsistency to interfere with contract operations.
+
+
+### Impact
+
+- **Data Integrity Violation:** The mappings lose their integrity due to duplicate indices and incorrect associations, leading to unreliable data.
+- **Operational Failures:** Frontend applications and contract functions that rely on these mappings may malfunction, causing errors for users and disrupting normal operations.
+- **Security Vulnerabilities:** Malicious actors could exploit the corrupted state to perform unauthorized actions, manipulate data, cause denial-of-service conditions, or misrepresent the contract state.
+
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+To resolve this issue, the deletion functions in all affected contracts should be corrected to properly handle element removal:
+
+**Adjust Deletion Logic:**
+- Decrease the count of active elements before performing operations that rely on it.
+- Only swap and update the mapping if the deleted element is not the last one.
+- Ensure that address(0) is not assigned a valid index in the mapping.
+
+**Maintain Consistency:**
+- After deletion, confirm that the array and mapping accurately represent the current state.
+- Prevent index duplication by correctly managing indices during deletion and addition of entities.
+
+By implementing these changes, the contracts will maintain data integrity, prevent operational failures, and eliminate potential security vulnerabilities arising from corrupted mappings.

+# Initialized variable in Ownerships contract is never set, rendering the onlyOwner modifier useless.
+
+### Summary
+
+The _Ownerships_ contract has an _initialized_ storage variable which is intended to track whether the contract has been initialized or not and is supposed to be set to true when the _setDebitaContract()_ function is called.
+
+This _initialized_ variable is used for the _onlyOwner_ modifier which is used for the _setDebitaContract()_ and _transferOwnership()_ functions.
+
+As a result of _initialized_ never being assigned it defaults to false, which lets the owner transfer ownership and change the aggregator contract address even after it has been set once.
+
+### Root Cause
+
+The _initialized_ variable ([DebitaLoanOwnerships.sol:18](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLoanOwnerships.sol#L18)) is not being set to true when calling [_setDebitaContract()_](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLoanOwnerships.sol#L40-L42).

+# If no one will lend a principle in epoch, then incentivise for it will be stuck on the contract
+
+### Summary
+
+Let's take a look at the contract
+[`DebitaIncentivize`](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L5).
+
+This contract allows anyone to reward the use of certain tokens as principle in a particular epoch.
+However, the contract does not provide for the case where the principle is not used at all in a given epoch - in which case the rewards that were sent for that pair (principle, epoch) will simply be stuck on the contract.
+
+Let's take a look at how the distribution of incenties goes. It takes place in the `claimIncentives` function
+
+```solidity
+ function claimIncentives(
+ address[] memory principles,
+ address[][] memory tokensIncentives,
+ uint epoch
+ ) public {
+ // get information
+ require(epoch < currentEpoch(), "Epoch not finished");
+
+ for (uint i; i < principles.length; i++) {
+ address principle = principles[i];
+ uint lentAmount = lentAmountPerUserPerEpoch[msg.sender][
+ hashVariables(principle, epoch)
+ ];
+ // get the total lent amount for the epoch and principle
+ uint totalLentAmount = totalUsedTokenPerEpoch[principle][epoch];
+
+ uint porcentageLent;
+
+ if (lentAmount > 0) {
+ porcentageLent = (lentAmount * 10000) / totalLentAmount;
+ }
+
+ uint borrowAmount = borrowAmountPerEpoch[msg.sender][
+ hashVariables(principle, epoch)
+ ];
+ uint totalBorrowAmount = totalUsedTokenPerEpoch[principle][epoch];
+ uint porcentageBorrow;
+
+ require(
+ borrowAmount > 0 || lentAmount > 0,
+ "No borrowed or lent amount"
+ );
+
+ porcentageBorrow = (borrowAmount * 10000) / totalBorrowAmount;
+
+ for (uint j = 0; j < tokensIncentives[i].length; j++) {
+ address token = tokensIncentives[i][j];
+ uint lentIncentive = lentIncentivesPerTokenPerEpoch[principle][
+ hashVariables(token, epoch)
+ ];
+ uint borrowIncentive = borrowedIncentivesPerTokenPerEpoch[
+ principle
+ ][hashVariables(token, epoch)];
+ require(
+ !claimedIncentives[msg.sender][
+ hashVariablesT(principle, epoch, token)
+ ],
+ "Already claimed"
+ );
+ require(
+ (lentIncentive > 0 && lentAmount > 0) ||
+ (borrowIncentive > 0 && borrowAmount > 0),
+ "No incentives to claim"
+ );
+ claimedIncentives[msg.sender][
+ hashVariablesT(principle, epoch, token)
+ ] = true;
+
+ uint amountToClaim = (lentIncentive * porcentageLent) / 10000;
+ amountToClaim += (borrowIncentive * porcentageBorrow) / 10000;
+
+ IERC20(token).transfer(msg.sender, amountToClaim);
+
+ emit ClaimedIncentives(
+ msg.sender,
+ principle,
+ token,
+ amountToClaim,
+ epoch
+ );
+ }
+ }
+ }
+```
+
+If lentAmount for each user is 0 (like totalLentAmount, like borrowAmount ) - then the function will not execute because of require
+```solidity
+require(
+ borrowAmount > 0 || lentAmount > 0,
+ ‘No borrowed or lent amount’
+ );
+```
+If there are no loans from principle in a given era, no one will be able to take the rewards.
+Fields that will remain 0 are changed only when calling the `updateFunds` function that is called at `matchedOffersV3` - that is, if there will never be any offer matched in epoch, then all fields will stay zero
+
+### Root Cause
+
+There is no provision for edge case when there were no loans at all in epoch
+
+### Internal pre-conditions
+
+Somebody's taking over future epoch for any principle token
+No-one incentivize this principle in this epoch
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact

+The probability that no one will make a loan in a particular era with a given principle is low.
+
+However, impact is high, stuck tokens.
+
+Severity medium
+
+### PoC
+
+_No response_
+
+### Mitigation
+

+# Insufficient Validation of sequencerUptimeFeed Status in Sequencer Check Logic
+
+### Summary
+
+The [chainlink docs](https://docs.chain.link/data-feeds/l2-sequencer-feeds) says that `sequencerUptimeFeed` can return a 0 value for `startedAt` if it is called during an "invalid round".
+
+> * startedAt: This timestamp indicates when the sequencer changed status. This timestamp returns `0` if a round is invalid. When the sequencer comes back up after an outage, wait for the `GRACE_PERIOD_TIME` to pass before accepting answers from the data feed. Subtract `startedAt` from `block.timestamp` and revert the request if the result is less than the `GRACE_PERIOD_TIME`.
+
+Please note that an "invalid round" is described to mean there was a problem updating the sequencer's status, possibly due to network issues or problems with data from oracles, and is shown by a `startedAt` time of 0 and `answer` is 0
+
+
+
+### Root Cause
+

+# POTENTIAL DOS ATTACK IN THE `DebitaIncentives.sol::claimIncentives` FUNCTION, CAUSED BY UNBOUNDED NESTED FOR LOOP, POTENTIALLY RESULTING IN USER FUNDS BEING LOCKED UP.
+
+# SUMMARY
+The `claimIncentives` function in `DebitaIncentives.sol` is vulnerable to a potential Denial-of-Service (DoS) attack due to unbounded nested loops over user-supplied arrays (`principles` and `tokensIncentives`). This could lead to excessive gas consumption, making the function unusable for real users and potentially locking up their funds.
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaIncentives.sol#L150
+
+---
+
+# ROOT CAUSE
+The vulnerability arises from the function iterating over two user-supplied arrays:
+1. **`principles`**: A single loop iterates over its length without any restriction, allowing an attacker to supply a large array.
+2. **`tokensIncentives[i]`**: For each `principle`, a nested loop iterates over the corresponding incentives array, further compounding the gas cost if both arrays are large.
+
+Additionally, the function relies on mappings for calculations (`lentAmountPerUserPerEpoch`, `totalUsedTokenPerEpoch`, etc.), but these mappings are not validated for bounds or integrity, potentially compounding gas costs.
+
+---
+
+# INTERNAL PRECONDITION
+1. The contract assumes that:
+ - `principles` and `tokensIncentives` arrays are of manageable lengths.
+2. It does not validate or impose length constraints on `principles` or `tokensIncentives`.
+
+
+---
+
+# EXTERNAL PRECONDITION
+1. An attacker has the ability to call the `claimIncentives` function and supply large arrays (`principles` and `tokensIncentives`).
+2. There are no explicit mechanisms to restrict maliciously large inputs or enforce gas efficiency.
+3. The function is called in a high-usage scenario where legitimate users depend on it for claiming their funds.
+
+---
+
+# ATTACK PATH
+1. The attacker calls `claimIncentives`, supplying:
+ - A very large `principles` array.
+ - Nested `tokensIncentives` arrays of significant size for each entry in `principles`.
+2. The excessive iterations in the unbounded loops consume all the available gas, leading to the function execution being reverted.
+3. Legitimate users are unable to claim their incentives due to the high gas requirement or repeated reverts caused by malicious inputs.
+
+---
+
+# MITIGATION
+1. **Impose Length Constraints**:
+```diff
++ uint256 public constant MAX_LIMIT = 50;
+ function claimIncentives(
+ address[] memory principles,
+ address[][] memory tokensIncentives,
+ uint epoch
+ ) public {
+ require(epoch < currentEpoch(), "Epoch not finished");
+ // e for looop from zero o the lenght of the principle
+ // @audit suspect DOS, as long as principle length can be accessed it can be increased to cause a DOS
++ require(principles.length <= MAX_LIMIT, "Array size too large");
+ require (tokensIncentives[i].length <= MAX_LIMIT, "Limit too large");
+ for (uint i; i < principles.length; i++) {
+ /// contiuation of code to the next loop
+ }
+ }
+
+```
+2. **Batch Processing**:
+ - Break the claim process into smaller chunks that can be processed in separate tx.

+# Calling `changePerpetual()` can result in `deleteOrder()` being called, but failling to disactivate the order.
+
+### Summary
+
+When `changePerpetual(false)` is called for a loan with `availableAmount == 0` the order is removed, because it means that the lender changed their mind about accumulating the interest in the order contract:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L182-L184
+The issue is that it fails at disactivating the order permanently which is the opposite of what `deleteOrder()` does.
+
+### Root Cause
+
+The `isActive` flag is not set to false in `changePerpetual()` when `availableAmount` is `0` and `perpetual` is `false`.
+
+### Internal pre-conditions
+
+- a lend order that was perpetual and utilized all available amount for a match is set to non-perpetual
+
+### External pre-conditions
+
+--
+
+### Attack Path
+
+1. Valid lend offer is created with perpetual set to `true`.
+2. It's matched with a borrow order utilizing all of the available amount.
+3. Owner changes their mind and decides to make the order non-perpetual.
+4. Owner can call `addFunds()`, `updateLendOffer()` and `acceptLendingOffer()` to utilize the same contract again.
+
+
+
+### Impact
+
+Core functionality not working - a canceled offer can still be used.
+
+
+### PoC
+
+Change this to `true` to set the lend offer as perpetual:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/test/local/Loan/TwoLendersERC20Loan.t.sol#L143
+and the following to `0` - for simplicity we are creating lend order with available amount `0` as if it was used already matched:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/test/local/Loan/TwoLendersERC20Loan.t.sol#L155
+
+
+The add this test case to `TwoLendersERC20Loan.t.sol`:
+```solidity
+ function test_changePerpetual() public {
+ LendOrder.changePerpetual(false);
+ DLOImplementation.LendInfo memory lendInformation = LendOrder.getLendInfo();
+ assertEq(lendInformation.perpetual, false);
+ assertEq(lendInformation.availableAmount, 0);
+ assertEq(LendOrder.isActive(), true);
+ }
+```
+
+This is very minimalistic to show the impact for this root cause. Separate finding shows how `addFunds()` (and other functions) can be called for deleted order.
+
+
+### Mitigation
+
+Consider the following change to the `changePerpetual()` function:
+```diff
+function changePerpetual(bool _perpetual) public onlyOwner nonReentrant {
+ require(isActive, "Offer is not active");
+
+ lendInformation.perpetual = _perpetual;
+ if (_perpetual == false && lendInformation.availableAmount == 0) {
++ isActve = false;
+ IDLOFactory(factoryContract).emitDelete(address(this));
+ IDLOFactory(factoryContract).deleteOrder(address(this));
+ } else {
+ IDLOFactory(factoryContract).emitUpdate(address(this));
+ }
+ }
+```
+Which is similar to what `acceptLendingOffer()` does under similar conditions.

+# claimCollateralAsLender() burns the lender's ownership even if they did not claim the collateral in claimCollateralAsNFTLender()
+
+### Summary
+
+In some cases, claimCollateralAsNFTLender() will not transfer the collateral but will still burn the lender's ownership.
+
+### Root Cause
+
+In DebitaV3Loan.sol claimCollateralAsLender() burns the ownership of a lender even if they didn't receive the collateral because it does not revert. So anytime there are more than 1 lenders in a loan and there is no auction initialized on the collateral, lenders calling claimCollateralAsLender() will just get their ownership burnt and will have no way of retrieving it.
+```solidity
+ function claimCollateralAsLender(uint index) external nonReentrant {
+ LoanData memory m_loan = loanData;
+ infoOfOffers memory offer = m_loan._acceptedOffers[index];
+ IOwnerships ownershipContract = IOwnerships(s_OwnershipContract);
+ require(
+ ownershipContract.ownerOf(offer.lenderID) == msg.sender,
+ "Not lender"
+ );
+ // burn ownership
+> ownershipContract.burn(offer.lenderID);
+ uint _nextDeadline = nextDeadline();
+
+ require(offer.paid == false, "Already paid");
+ require(
+ _nextDeadline < block.timestamp && _nextDeadline != 0,
+ "Deadline not passed"
+ );
+ require(offer.collateralClaimed == false, "Already executed");
+
+ // claim collateral
+ if (m_loan.isCollateralNFT) {
+ claimCollateralAsNFTLender(index);
+ } else {
+ ...
+ }
+ Aggregator(AggregatorContract).emitLoanUpdated(address(this));
+ }
+
+ function claimCollateralAsNFTLender(uint index) internal returns (bool) {
+ LoanData memory m_loan = loanData;
+ infoOfOffers memory offer = m_loan._acceptedOffers[index];
+ loanData._acceptedOffers[index].collateralClaimed = true;
+
+ if (m_loan.auctionInitialized) {
+ ...
+ } else if (
+ m_loan._acceptedOffers.length == 1 && !m_loan.auctionInitialized
+ ) {
+ ...
+ }
+ return false;

+# A lender can lend whitout having a collateral used
+
+### Summary
+
+Because a rounding down the collateral used for a lender can be eqal to 0 which mean that the lender lend an amount without using any collateral and the matchOffersV3 call can revert because of it.
+
+### Root Cause
+
+Consider this code from the matchOffersV3 function of the DebitaV3Aggregator contract :
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L462-L474
+
+Here the ratio is eqal to the ration of the lender adjusted with the percentage specified by the caller for this lend offer
+The ratio of the lend offer is eqal to the ratio specified by the lender or if the oracle is enabled the ratio will be calculated based on the prices of the two assets as we can see here :
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L440-L460
+
+The problem is that for certain assets and lend amont this calculation can round down to zero :
+
+```solidity
+ uint userUsedCollateral = (lendAmountPerOrder[i] *
+ (10 ** decimalsCollateral)) / ratio;
+```
+especially for collaterals that have less decimals precision than the principal and when the price of the collateral his higher than the price of the principle.
+
+
+### Internal pre-conditions
+
+1. The decimal precision of the collateral must be higher of the decimals of the principle
+
+### External pre-conditions
+
+1.The price of the collateral should be higher than the one of the principle.
+
+### Attack Path
+
+1. A mallicious user want to drain lend orders
+2. He create a borrow order with collateral and principle that conform to the pre-conditions like for instance collateral = WBTC and principle=USDC
+
+### Impact
+
+The borrower wil be able to borrow am amount much higher than his collateral. In some case the call in matchOffersV3 can revert because of a division by zero.
+
+### PoC
+
+You can copy paste this code in a file in the test folder and run forge test --mt test_matchOffersV3POC to run the POC
+
+The setUp only deploy the contracts of the protocol the mocks for tokens and priceFeeds. The setUp also set the price of an USDC to 1 dollar and the price of a WBTC of 90000 dollars

+
+Every Chainlink feed has a minimum and maximum price. However, due to the circuit breaker, if an asset's price moves outside these limits, the provided answer will still be capped.
+
+This can lead to an incorrect price if the actual price falls below the aggregator's `minAnswer`, as Chainlink will continue providing the capped value instead of the true one.
+
+The Chainlink documentation notes that "On most data feeds, these values are no longer used and they do not prevent your application from reading the most recent answer.". However, this is not the case on Arbitrum, as for most data feeds (including ETH and most stablecoins), these values are indeed used, for example, the ETH/USD aggregator

+# A malicious lender can obstruct legitimate lenders from canceling or fully fulfilling their offers if the offer is not perpetual.
+
+### Summary
+
+A malicious Lender can exploit the cancellation process of a lender's offer by invoking the `addFund` function followed by the `cancelOffer` function. This allows them to decrease the `activeOrdersCount` multiple times for the same order, resulting in a DoS for the current offer. As a consequence, the lenders of other offers are unable to cancel and the complete fulfill of the offer can not be executed, preventing its deletion from the `DebitaLendOfferFactory` contract.
+
+
+### Root Cause
+
+ [Here](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaLendOffer-Implementation.sol#L162-L175). The owner can calls `addFund` to not `activeOrders`.
+
+
+### Internal pre-conditions
+
+The order is already deleted from `DebitaLendOfferFactory` either after completion or the owner decided to `cancelOffer`.
+
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. The Lender will calls `addFund` to closed order.
+2. The Lender calls the `cancelOffer`.
+3. This Attack will decrements the `activeOrdersCount` twice for same order and the attacker can repeat this attack to DoS all Current Offers or `activeOrdersCount` becomes 0.
+
+
+### Impact
+
+The existing orders cannot be canceled and cannot be fully fulfilled. In case if current Lenders want to withdraw assets it will result in lose of assets for Lender.

+# Lender can loose collateral in DebitaV3Loan when auction is not initialized
+
+### Summary
+
+When a loan with nft collateral has been defaulted, a lender attempting to claim their collateral before the collateral has been autioned will loose their collateral and their ability to re-claim it later on( i.e. after it has been auctioned)
+
+
+### Root Cause
+
+In `DebitaV3Loan::claimCollateralAsLender` calls the `claimCollateralAsNFTLender` function to claim the collateral is an NFT.
+The `claimCollateralAsNFTLender` function returns `true` when the claim is successful and `false` when the claim is not successful.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L374-L411
+
+ The issue is that the calling finction (`DebitaV3Loan::claimCollateralAsLender`) does not handle the case where the claim is not successful as a result the `lendoffer.collateralClaimed` will be `true` even though the lender did not claim the collateral and they'll be unable to claim it again.

+# The DebitaV3Aggregator.matchOffersV3() function reverts when lendOrders's length is greater than 30 due to inconsistency of parameters
+
+### Summary
+
+In the DebitaV3Aggregator.matchOffersV3() function, there is a check for lendOrders.length, which should be equal or less than 100. This function deploys a DebitaV3Loan proxy and invokes initialize() function.
+
+However, in DebitaV3Loan.initialize() function there is restriction about _acceptedOffers.length should be less than 30, which contradicts to a check of DebitaV3Aggregator.matchOffersV3() function.
+
+### Root Cause
+
+In the [DebitaV3Aggregator.sol:290](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L290) function, there is a check for lendOrders.length, which should be equal or less than 100.
+
+```solidity
+ function matchOffersV3(
+ address[] memory lendOrders,
+ uint[] memory lendAmountPerOrder,
+ uint[] memory porcentageOfRatioPerLendOrder,
+ address borrowOrder,
+ address[] memory principles,
+ uint[] memory indexForPrinciple_BorrowOrder,
+ uint[] memory indexForCollateral_LendOrder,
+ uint[] memory indexPrinciple_LendOrder
+ ) external nonReentrant returns (address) {
+
+ ...
+
+@> require(lendOrders.length <= 100, "Too many lend orders");
+
+ ...
+ }
+```
+
+Also in the [DebitaV3Loan.sol:156](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L156) function, there is restriction for the length of _acceptedOffers should be less than 30.
+
+
+```solidity
+ function initialize(
+ address _collateral,
+ address[] memory _principles,
+ bool _isCollateralNFT,
+ uint _NftID,
+ uint _collateralAmount,
+ uint _valuableCollateralAmount,
+ uint valuableCollateralUsed,

+ address _feeAddress
+ ) public initializer nonReentrant {
+
+ ...
+
+@> require(_acceptedOffers.length < 30, "Too many offers");
+
+ ...
+ }
+```
+
+However, the length of lendOrders and _acceptedOffers is equal, so when it is greater than 30, the DebitaV3Loan.initialize() function will revert.

+
+### Summary
+
+DLOImplementation::addFunds method is used to addFunds ether from paying debt/interests in DebitaV3Loan or directly from lend offer owner. When calling this method, isActive state should be checked.
+
+### Root Cause
+
+DLOImplementation::addFunds function is for add funds to lend offer. The funds may ether from payed debt/interests or from the lender owner. However when the lender is fulfilled and perpetual is set to false, the lender offer will be deleted from factory contract, in the situation, isActive is set to false. addFunds function should not permit funds extending in such cases.

+# Incorrect calculation of `extendedTime`
+
+### Summary
+
+In the `DebitaV3Loan.sol` contract, the `extendLoan` function doesn't calculate `extendedTime` correctly because `block.timestamp` is subtracted twice. This can lead to negative or inaccurate `extendedTime`.
+
+### Root Cause
+
+When calculating [extendedTime](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L590-L592), the formula incorrectly subtracts `block.timestamp` twice: once as part of [alreadyUsedTime](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L588) (`block.timestamp - m_loan.startedAt`), and then again in the calculation of `extendedTime`.
+
+```solidity
+ uint alreadyUsedTime = block.timestamp - m_loan.startedAt;
+
+ uint extendedTime = offer.maxDeadline -
+ alreadyUsedTime -
+ block.timestamp;
+```
+
+### Internal pre-conditions
+
+Example Scenario:
+
+`block.timestamp = 6`
+`m_loan.startedAt = 0`
+`offer.maxDeadline = 10`
+
+`alreadyUsedTime` is calculated:
+`alreadyUsedTime = block.timestamp - m_loan.startedAt;`
+alreadyUsedTime = 6 - 0 = 6
+
+`extendedTime` is calculated:
+`extendedTime = offer.maxDeadline - alreadyUsedTime - block.timestamp;`
+extendedTime = 10 - 6 - 6 = -2
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+The incorrect calculation causes the `extendLoan` function to revert whenever `extendedTime` becomes negative. It may also produce inaccurate values, resulting in improper fee calculations. This prevents users from successfully extending their loans, potentially leading to loan defaults or financial losses.
+
+### PoC

+# DebitaV3Loan::extendLoan can be DoSed due to underflow arithmetic
+
+### Summary
+
+`DebitaV3Loan::extendLoan` does an unchecked subtraction that can lead to an underflow under certain conditions DoSing the function i.e preventing the borrower from extending the loan
+
+
+### Root Cause
+
+In `DebitaV3Loan::extendLoan` the function does the following
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L588-L592
+
+```solidity
+ uint alreadyUsedTime = block.timestamp - m_loan.startedAt;
+ uint extendedTime = offer.maxDeadline -
+ alreadyUsedTime -
+ block.timestamp;
+```
+The issue is that `block.timestamp + alreadyUsedTime` can be greater than `offer.maxDeadline` which will cause the function to revert due to an underflow.
+
+consider the following example:
+for simplicity we'll assume the loan started at 0.
+- m_loan.startedAt = 0
+- offer.maxDeadline = 100
+- block.timestamp = 70
+- alreadyUsedTime = 70 - 0 = 70
+- extendedTime = 100 - 70 - 70 = -40
+The function will revert due to underflow

+# Missing Length Checks in `matchOffersV3` Function (Aggregator Contract)
+
+### Summary
+
+The matchOffersV3 function in the Aggregator Contract lacks explicit checks to ensure that critical input arrays,
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L283
+
+such as `lendOrders`, `lendAmountPerOrder`, `porcentageOfRatioPerLendOrder`, and others, are of consistent lengths where necessary. This missing validation introduces potential issue which can lead to
+- Mismatched Inputs: Logic errors or unintended behavior if input arrays are incorrectly sized.
+- Protocol Disruptions: Operations will fail mid-execution and the loan

+1. The for loop uses lendOrders.length to iterate, but the processing logic references other arrays (lendAmountPerOrder, porcentageOfRatioPerLendOrder, etc.) without verifying their lengths.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L317
+
+ If lendOrders is shorter than other arrays then :
+
+ • The function processes fewer iterations than necessary, leaving unprocessed orders in the longer arrays.
+ • This could result in partial loans, leaving lenders or borrowers with incomplete matches.
+ If lendOrders = [0x1, 0x2] and lendAmountPerOrder = [100, 200, 300], only the first two entries of lendAmountPerOrder are processed. The third entry (300) is ignored, leading to incomplete order processing.
+
+2. Array Index Out-of-Bounds Reversion will happen If an array referenced within the loop (e.g., `lendAmountPerOrder`) is shorter than lendOrders, the function will attempt to access an index that doesn’t exist.
+The transaction will revert with an “index out of bounds” error, leaving all operations unprocessed.
+
+**Impact of Lenders and Borrowers:**
+Partial matches could leave their capital idle, earning no returns for the lenders.

+# Improper contract ownership transfer mechanism could lead to a loss of control over key protocol components
+
+### Summary
+
+The ownership of contracts `DebitaLoanOwnerships.sol` and `AuctionFactory.sol` is changed without doing some key necessary checks.
+
+This could lead to a loss of control over these two contracts.
+
+### Root Cause
+
+The ownership of the smart contract is transferred to another address without doing
+
+- a zero check, and
+- a verification of the new address
+
+This happens in two contracts.
+
+First is in `DebitaLoanOwnerships.sol` at [L111](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaLoanOwnerships.sol#L111)

+# Missing Stale Price Check in DebitaChainlink Contract Could Lead to Incorrect Price Calculations
+
+### Summary
+
+The lack of a stale price check in the `DebitaChainlink` contract's `getThePrice` function will cause **potentially incorrect calculations** for **protocol users and downstream operations** as the contract relies solely on the `price > 0` check, ignoring the timestamp data from Chainlink's `latestRoundData()` response. This opens up the protocol to risks associated with stale prices, as highlighted in the [Chainlink documentation](https://docs.chain.link/docs/historical-price-data/#historical-rounds).
+
+
+### Root Cause
+
+
+In the following code snippet:
+```solidity
+(, int price, , , ) = priceFeed.latestRoundData();
+require(price > 0, "Invalid price");
+```
+the contract does not validate whether the price fetched is stale by checking the `updatedAt` timestamp returned by the `latestRoundData()` function.
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/oracles/DebitaChainlink.sol#L30-L47
+
+### Internal pre-conditions
+
+1. The Chainlink oracle must return stale data due to an external issue (e.g., lack of updates or malfunction in the price feed).
+2. The protocol must invoke `getThePrice` without validating the freshness of the price data.
+3. Downstream functions or calculations using the stale price must assume it is valid, leading to incorrect outputs.
+
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+_No response_
+
+### Impact
+
+
+The protocol suffer a potential loss due to calculations based on outdated price data.
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+Introduce a stale data validation step by comparing the `updatedAt` timestamp of the price feed against the current block timestamp. Ensure this check is integrated into the `getThePrice` function. For example:
+
+```solidity
+(uint80 roundId, int price, , uint256 updatedAt, uint80 answeredInRound) = priceFeed.latestRoundData();
+require(price > 0, "Invalid price");
+require(updatedAt + 1 hours > block.timestamp, "Stale price data");
+require(answeredInRound >= roundId, "Incomplete round");
+```

+
+### Summary
+
+When a loan has been partially defaulted i.e. the borrower did not repay the loan fully, the collateral tokens backing the already paid loans will be stuck in the contract indefinitely

+
+### Root Cause
+
+In `DebitaV3Loan` when a loan is defaulted by the borrower the collateral can be claimed by the lenders based on their respective principle amount and ratio.

+
+However when the loan is partially defaulted (i.e. the borrower repayed some lenders) the collateral left in the contract will stil be claimable by the unpaid lenders, but because the loan was partially defaulted not all the collateral can be claimed by the lenders.
+The remaining collateral in this scenario will be stuck in the contract as it can neither be retrieved by the borrower or the protocol

+# Mismatch of limits for lend order in `Aggregator` and `Loan`
+
+### Summary
+
+The `matchOffersV3` function allows a [maximum of 100](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L290) lend orders to be used to close a single borrow order.
+```solidity
+require(lendOrders.length <= 100, "Too many lend orders");
+```
+However, when a `Loan` contract is created in the same function and `Loan::initialize` is called, where the offers array - essentially the same as the lendOrders array - is passed, the initialise function already limits its length to [only 30](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L156).
+```solidity
+ require(_acceptedOffers.length < 30, "Too many offers");
+```
+
+As I said above, acceptedOffers is an array that is formed from the elements of lendOrders and has the same length. So it is not normal when the limits in entrypoint are larger than the limits in the function that will be called afterwards.
+
+Thus, anyone who calls the matchOffersV3 function and inserts more than 30 lendOrders, thinking that the limit is 100, will not be able to execute the function.
+
+### Root Cause
+
+Mismatch of limits for the same arrays
+
+### Internal pre-conditions
+
+Someone is calling the matchOffersV3 function using a limit of 100, not 30

+
+This is an obvious error in the protocol code. I don't know what the intended limit on the number of orders is, but when the limit in entrypoint is greater than the limit in the derived call - it creates confusion for those who will call matchOffersV3.
+
+If it were the other way round and the limit in the entrypoint was less than the limit in the derivative call and no transaction fell - that would be acceptable, but in this formation I'm thinking medium severity

+# Users Pays Max Fee Regardless of Deadline period When Extending a Loan
+
+### Summary
+
+The `DebitaV3Loan::extendLoan()` function contains a logical error, causing users to pay the max fee regardless of the deadline period when extending a loan.
+
+
+### Root Cause
+
+1. The issue lies in the following function:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts//DebitaV3Loan.sol#L602
+```solidity
+@> uint feeOfMaxDeadline = ((offer.maxDeadline * feePerDay) /
+ 86400);
+ if (feeOfMaxDeadline > maxFee) {
+ feeOfMaxDeadline = maxFee;
+ } else if (feeOfMaxDeadline < feePerDay) {
+ feeOfMaxDeadline = feePerDay;
+ }
+```
+As shown, since `offer.maxDeadline` is a very large value, `feeOfMaxDeadline` will always be equal to the `maxFee`.
+
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. A user attempts to extend a loan with max deadline period of `15 days`.
+2. Due to the above logical errro, the user ends up paying a fee for `20 days` (`maxFee`) instead of `15 days`.
+
+
+### Impact
+
+Loss of user's funds as the users are charged higher fees than they should be.
+
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+It is recommended to subtract `m_loan.startedAt` from `offer.maxDeadline`:
+```diff
+- uint feeOfMaxDeadline = ((offer.maxDeadline * feePerDay) /
++ uint feeOfMaxDeadline = (((offer.maxDeadline - m_loan.startedAt) * feePerDay) /
+ 86400);
+ if (feeOfMaxDeadline > maxFee) {
+ feeOfMaxDeadline = maxFee;
+ } else if (feeOfMaxDeadline < feePerDay) {
+ feeOfMaxDeadline = feePerDay;

+# Mistaken Variable Overwrite in changeOwner Function Prevents Ownership Change
+
+### Summary
+
+The changeOwner function erroneously uses the owner state variable as both the function parameter and the assignment target, leading to a logical flaw. This mistake prevents the owner from being updated as intended. As a result, ownership transfer functionality is entirely broken, leaving the contract stuck with its initially assigned owner.
+
+
+
+### Root Cause
+
+The use of owner as both the name of the function parameter and the state variable. This causes the assignment owner = owner to always refer to the function parameter, which effectively has no effect on the owner state variable.

+# buyNFT is vulnerable to front-running attack.
+
+### Summary
+
+The [DutchAuction_veNFT](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L31) contract follows Dutch Auction system which means auction starts with a high price and the price decreases at certain interval until the price seems reasonable for someone to bid. Instead of directly buying the NFT an attacker can just wait for someone to signal that they are interested in buying the NFT and after seeing the signal the attacker can call [DutchAuction_veNFT.buyNFT()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109) and frontrun the legit buyer by providing more gas or reordering(in case the attacker is a miner) the transaction list giving his transaction higher priority.

+
+### Attack Path
+
+Attacker type: miner or a normal account with high gas price.
+
+1. Instead of buying the NFT at current price attacker waits for someone to show interest in the NFT.
+2. Attacker monitors any transaction that shows someone sent an approval call to the sellingToken contract or to [DutchAuction_veNFT.buyNFT()](https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/auctions/Auction.sol#L109).
+3. Attacker constructs similar transaction and broadcast it with higher gas price or reorders(in case the attacker is a miner) the transaction list giving his transaction higher priority.
+4. Attacker wins the auction and the legit bidder's transaction fails.
+
+### Impact
+
+1. Normal legit bidders might loose interest in the auction leaving only the miners to bid.
+2. Since there aren't many competitors the auctioned NFT is at the risk of selling at floor price. The NFT seller will loose money.

+# Double Decimal Multiplication Between MixOracle and Aggregator Leads to Incorrect Price Calculations
+
+## Summary
+
+The `getThePrice()` function in `MixOracle.sol` applies decimal scaling to raw prices, but these prices are scaled again in `matchOffersV3()` function in `DebitaV3Aggregator.sol`, leading to incorrect price calculations that can affect core functionality like LTV calculations and collateral valuations.
+
+## Vulnerability Detail
+
+The main issue happens because of price scaling is performed twice:
+
+1. First in `MixOracle.sol:40`:
+```solidity
+function getThePrice(address tokenAddress) public returns (int) {
+ // get TWAP price from token1 in token0
+ (uint224 twapPrice112x112, ) = priceFeed.getResult(uniswapPair);
+ address attached = AttachedPricedToken[tokenAddress];
+
+ // Get the price from the pyth contract
+ int attachedTokenPrice = IPyth(debitaPythOracle).getThePrice(attached);
+ uint decimalsToken1 = ERC20(attached).decimals();
+ uint decimalsToken0 = ERC20(tokenAddress).decimals();
+
+ // @audit First decimal multiplication happens here
+ int amountOfAttached = int(
+ (((2 ** 112)) * (10 ** decimalsToken1)) / twapPrice112x112
+ );
+
+ // @audit Price already includes decimal scaling
+ uint price = (uint(amountOfAttached) * uint(attachedTokenPrice)) /
+ (10 ** decimalsToken1);
+
+ return int(uint(price));
+}
+```
+2. Then again in DebitaV3Aggregator.sol:440:
+```solidity
+if (lendInfo.oraclesPerPairActivated[collateralIndex]) {
+ uint priceCollateral_LendOrder = getPriceFrom(
+ lendInfo.oracle_Collaterals[collateralIndex],
+ borrowInfo.valuableAsset
+ );
+ uint pricePrinciple = getPriceFrom(
+ lendInfo.oracle_Principle,
+ principles[principleIndex]
+ );
+
+ // @audit Second decimal multiplication happens here
+ uint fullRatioPerLending = (priceCollateral_LendOrder *
+ 10 ** decimals) / pricePrinciple;
+}
+```
+## Impact
+
+This double decimal multiplication causes prices to be inflated by an additional decimal factor, leading to:
+
+- Incorrect collateral valuations
+- Wrong LTV calculations
+- Mispriced loans
+- Incorrect liquidation thresholds
+- Wrong incentive distributions
+
+The severity is high because it directly affects core price calculations that determine loan conditions and collateral requirements.
+
+## Code Snippet
+
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/oracles/MixOracle/MixOracle.sol#L40
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274
+
+## Tool Used
+
+Manual Review
+
+## Recommendation
+
+Remove the decimal scaling from `MixOracle.getThePrice()` and keep it only in the `DebitaV3Aggregator`. This will ensure that decimal scaling happens in one place only and maintains consistency across all oracle price feeds.

+# Incorrect State Update(EFFECT) Sequence Causes `DebitaV3Loan.sol::payDebt` Function to Always Revert.
+
+# SUMMARY
+The `DebitaV3Loan.sol::payDebt` function contains a critical sequence error where it sets `offer.paid = true` before checking if the offer was already paid, causing all payment attempts to revert. This makes the core payment functionality of the contract completely inoperable.
+
+# ROOT CAUSE
+The vulnerability exists in the following code sequence:
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Loan.sol#L205
+```solidity
+// Sets paid to true first
+loanData._acceptedOffers[index].paid = true;
+
+// Then checks if it was previously paid
+require(offer.paid == false, "Already paid");
+```
+Since the state is updated before validation, the `require` check will always fail, as `offer.paid` is already set to true when the check occurs.
+
+# Internal Precondition:
+- Function caller must be the legitimate borrower
+- Current block timestamp must be before deadline
+- nonReentrant modifier must allow execution
+- Function must have valid array of indexes
+
+# External Precondition:
+- Borrower must have sufficient token balance
+- Borrower must have approved contract for token transfer
+- Loan offers must exist and be unpaid
+
+# ATTACK PATH
+1. Borrower calls `DebitaV3Loan.sol::payDebt` with valid index(es)
+2. Function updates `offer.paid` to true
+3. Function checks if `offer.paid` is false
+4. Check fails because `offer.paid` was just set to true
+5. Transaction reverts with "Already paid" message
+6. Result: Borrower cannot pay debt despite having funds and permission
+
+# MITIGATION
+1. Reorder operations to validate before state changes:
+```diff
+ function payDebt(uint[] memory indexes) public nonReentrant {

+# auction doesn't support TaxTokenReceipts, leading to the lender losing funds
+
+### Summary
+
+DebitaV3 support two NFT as collateral: TaxTokensReceipts and veNFTReceipts. And borrowers can use their collateral to accept liquidity from multiple lenders.If borrower doesn't pay the loan before deadline, then lender can call auction to sell the collateral NFT. But the auction doesn't support TaxTokenReceipts. The auction will revert in function `buyNFT` due to the limit of ` from` and `to`.
+So the lender can not claim collateral in this situation, leads to loss fund.
+
+### Root Cause
+
+In `Auction.sol`, function `buyNFT` https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/1465ba6884c4cc44f7fc28e51f792db346ab1e33/Debita-V3-Contracts/contracts/auctions/Auction.sol#L149
+It will transfer the NFT token to buyer.
+```solidity
+ IERC721 Token = IERC721(s_CurrentAuction.nftAddress);
+ Token.safeTransferFrom(
+ address(this),
+ msg.sender,
+ s_CurrentAuction.nftCollateralID
+ );

+The `TaxTokenReceipts` can not successfully transfer to buyer,so the auction about the collateral will always fail.
+
+Assume the situation:
+1. borrower choose TaxTokenReceipt as collateral
+2. The borrowOffer matches with 2 lendOffer
+3. borrower doesn't pay the loan before deadline
+4. The lenders want to claim collateral, they need to create auction for collateral first.
+5. The auction will always fail and the lender can not claim collateral.

+# Lack of Rate Limiting in `matchOffersV3` Enables Fee Monopolization and Borrower Exploitation
+
+### Summary
+
+The absence of rate limiting in the `matchOffersV3` function in the Aggregator contract allows a single user to monopolize the connector fee structure, repeatedly claiming fees for themselves. Borrowers can also exploit this by matching their own offers and redirecting the connector fees back to their wallet, undermining the fairness of the protocol.
+
+### Root Cause
+
+The `matchOffersV3`
+https://github.com/sherlock-audit/2024-11-debita-finance-v3/blob/main/Debita-V3-Contracts/contracts/DebitaV3Aggregator.sol#L274
+
+function does not include any mechanism to prevent the same user or borrower from repeatedly calling the function in a short span. There is no tracking or limitation of how many times a specific user or borrower can invoke the function to match offers and earn connector fees.
+
+### Internal pre-conditions
+
+_No response_
+
+### External pre-conditions
+
+_No response_
+
+### Attack Path
+
+1. Fee Monopolization:
+ • A single user continually calls matchOffersV3 to match various offers, ensuring they always earn the connector fees.
+ • Other users are excluded from participating or earning fees due to the high frequency of these transactions.
+2. Borrower Exploitation:
+ • A borrower creates both lending and borrowing offers.
+ • They repeatedly call matchOffersV3 to match their own offers, ensuring the connector fees are funneled back to their wallet.
+
+### Impact
+
+_No response_
+
+### PoC
+
+_No response_
+
+### Mitigation
+
+1. Implement Rate Limiting:
+ • Introduce a cooldown period between successive calls to matchOffersV3 by the same user.
+ • Use time-based or transaction count-based limits to ensure fair access to the function.
+2. Restrict Borrower-Connector Overlap:
+ • Add a check to prevent borrowers from acting as the connector for their own offers.
+ • Ensure the connector fee cannot be claimed by the borrower of a matched offer.
+3. Randomized Fee Distribution:
+ • Use a weighted random distribution mechanism to reward connector fees among multiple eligible users instead of a single one dominating.

+# Insufficient check for chainlink `isSequencerUp` can cause borrows to be filled with invalid price
+
+### Summary
+
+Per the audit README,
+
+> **On what chains are the smart contracts going to be deployed?**
+> Sonic (Prev. Fantom), Base, Arbitrum & OP
+
+The PriceFeed contract has sequencerUptimeFeed checks in place to assert if the sequencer on an L2 is running but these checks are not implemented correctly. The [chainlink docs ](https://docs.chain.link/data-feeds/l2-sequencer-feeds)say that sequencerUptimeFeed can return a 0 value for `startedAt` if "the Sequencer Uptime contract is not yet initialized".
+
+> **`startedAt`**: This timestamp indicates when the sequencer feed changed status. When the sequencer comes back up after an outage, wait for the GRACE_PERIOD_TIME to pass before accepting answers from the data feed. ....
+> ...The `startedAt` variable returns 0 only on Arbitrum when the Sequencer Uptime contract is not yet initialized.
+
+This can be possibly due to network issues or problems with data from oracles, and is shown by a `startedAt` time of 0 and `answer` is 0. Further explanation can be seen as given by an official chainlink engineer as seen [here](https://discord.com/channels/592041321326182401/605768708266131456/1213847312141525002) in the chainlink public discord
