x/vulndb: potential Go vuln in github.com/cilium/cilium: GHSA-3wwx-63fv-pfq6

[GoVulnBot]

Advisory GHSA-3wwx-63fv-pfq6 references a vulnerability in the following Go modules:

Module
github.com/cilium/cilium

Description:

Impact

A policy rule denying a prefix that is broader than /32 may be ignored if there is

• A policy rule referencing a more narrow prefix (CIDRSet or toFQDN) and
• This narrower policy rule specifies either enableDefaultDeny: false or - toEntities: all

Note that a rule specifying toEntities: world or toEntities: 0.0.0.0/0 is insufficient, it must be to entity all.

As an example, given the below policies, traffic is allowed to 1.1.1.2, when it should be denied:

apiVersion: cilium.io/v2
kind: CiliumClusterwideNetworkPolicy
metadata:
  name: block-scary-range
spec:...
