The proposal creation entrypoint (`propose`) in `GovernorCompatibilityBravo` allows the creation of proposals with a `signatures` array shorter than the `calldatas` array. This causes the additional elements of the latter to be ignored, and if the proposal succeeds the corresponding actions would eventually execute without any calldata. The `ProposalCreated` event correctly represents what will eventually execute, but the proposal parameters as queried through `getActions` appear to respect the original intended calldata. This issue has been patched in 4.8.3. As a workaround, ensure that all proposals that pass through governance have equal length `signatures` and `calldatas` parameters."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:H/A:L","baseScore":6.8,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"HIGH","availabilityImpact":"LOW"},"exploitabilityScore":2.1,"impactScore":4.7},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-20"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-noinfo"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:openzeppelin:contracts:*:*:*:*:*:node.js:*:*","versionStartIncluding":"4.3.0","versionEndExcluding":"4.8.3","matchCriteriaId":"411C30F2-953A-46C1-B290-F73D73742342"},{"vulnerable":true,"criteria":"cpe:2.3:a:openzeppelin:contracts_upgradeable:*:*:*:*:*:node.js:*:*","versionStartIncluding":"4.3.0","versionEndExcluding":"4.8.3","matchCriteriaId":"DE759E37-EAC7-4CDA-9AB1-0703E9398214"}]}]}],"references":[{"url":"https://github.com/OpenZeppelin/openzeppelin-contracts/releases/tag/v4.8.3","source":"security-advisories@github.com","tags":["Release Notes"]},{"url":"https://github.com/OpenZeppelin/openzeppelin-contracts/security/advisories/GHSA-93hq-5wgc-jc82","source":"security-advisories@github.com","tags":["Vendor Advisory"]},{"url":"https://github.com/OpenZeppelin/openzeppelin-contracts/releases/tag/v4.8.3","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Release Notes"]},{"url":"https://github.com/OpenZeppelin/openzeppelin-contracts/security/advisories/GHSA-93hq-5wgc-jc82","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
