CVE-2022-31198 Open this link in a new tabHow to fix?
Upgrade @openzeppelin/contracts-upgradeable to version 4.7.2 or higher.
Overview
@openzeppelin/contracts-upgradeable is a Secure Smart Contract library for Solidity.
Affected versions of this package are vulnerable to Incorrect Calculation via the GovernorVotesQuorumFraction module.
This vulnerability is exploitable by passing a proposal to lower the quorum requirements, leading to past proposals possibly becoming executable if they had been defeated only due to lack of quorum, and the number of votes it received meets the new quorum requirement.
Mitigation:
Users unable to upgrade should consider avoiding lowering quorum requirements if a past proposal was defeated for lack of quorum.
