How to Fix CVE-2022-31198

To remediate this vulnerability, upgrade all affected @openzeppelin/contracts dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@openzeppelin/contracts fixed: 4.7.2
npm install @openzeppelin/contracts@4.7.2
@openzeppelin/contracts-upgradeable fixed: 4.7.2
npm install @openzeppelin/contracts-upgradeable@4.7.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

npm ls @openzeppelin/contracts

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-31198, inspect your project dependencies using npm:

npm ls @openzeppelin/contracts

Analyze the terminal output to locate any version of @openzeppelin/contracts in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.7.2), your application is affected.

Note: The npm ls @openzeppelin/contracts command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-682: Incorrect Calculation, where the product performs a calculation that generates incorrect or unintended results that are later used in security-critical decisions or resource management. In @openzeppelin/contracts, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact This issue concerns instances of Governor that use the module `GovernorVotesQuorumFraction`, a mechanism that determines quorum requirements as a percentage of the voting token's total supply. In affected instances, when a proposal is passed to lower the quorum requirement, past proposals may become executable if they had been defeated only due to lack of quorum, and the number of votes it received meets the new quorum requirement. Analysis of instances on chain found only one proposal that met this condition, and we are actively monitoring for new occurrences of this particular issue. ### Patches This issue has been patched in v4.7.2. ### Workarounds Avoid lowering quorum requirements if a past proposal was defeated for lack of quorum. ### References https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3561 ### For more information If you have any questions or comments about this advisory, or need assistance deploying the fix, email us at [security@openzeppelin.com](mailto:security@openzeppelin.com).
