CVE-2022-31198 is a high-severity vulnerability affecting OpenZeppelin Contracts, specifically instances of Governor using the GovernorVotesQuorumFraction module. It allows previously defeated proposals to become executable if the quorum requirement is lowered and the proposal's votes meet the new, lower threshold. This vulnerability has a CVSS score of 7.5 (High) due to its network-based attack vector and high impact on integrity, with no user interaction required. While no active exploitation, public exploit code, or significant community discussion has been observed, users are advised to upgrade to v4.7.2 or avoid lowering quorum requirements if past proposals were defeated for lack of quorum.
