+# CWA-2024-004: Gas mispricing in cosmwasm-vm
+
+Some Wasm operations take significantly more gas than our benchmarks indicated. This can lead to missing the gas target we defined by a factor of ~10x. This means a malicious contract could take 10 times as much time to execute as expected, which can be used to temporarily DoS a chain.
