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.\n\nAnalysis of instances on chain found only one proposal that met this condition, and we are actively monitoring for new occurrences of this particular

Specifically, if the clashing function has a different signature with incompatible ABI encoding, the proxy could revert while attempting to decode the arguments from calldata. The probability of an accidental clash is negligible, but one could be caused deliberately and could cause a reduction in availability. The issue has been fixed in version 4.8.3. As a workaround if a function appears to be inaccessible for this reason, it may be possible to craft the calldata such that ABI decoding does not fail at the proxy and the function is properly proxied through.", "references": [ { "reference_url": "https://api.first.org/data/v1/epss?cve=CVE-2023-30541", "reference_id": "", "reference_type": "", "scores": [ { "value": "0.00452", "scoring_system": "epss", "scoring_elements": "0.64088", "published_at": "2026-06-06T12:55:00Z" }, { "value": "0.00452", "scoring_system": "epss", "scoring_elements": "0.6408", "published_at": "2026-06-05T12:55:00Z" } ], "url": "https://api.first.org/data/v1/epss?cve=CVE-2023-30541" }, { "reference_url": "https://github.com/OpenZeppelin/openzeppelin-contracts", "reference_id": "", "reference_type": "", "scores": [ { "value": "5.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/OpenZeppelin/openzeppelin-contracts" }, { "reference_url": "https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4154", "reference_id": "", "reference_type": "", "scores": [ { "value": "5.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2025-02-05T20:31:10Z/" } ], "url": "https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4154" }, { "reference_url": "https://github.com/OpenZeppelin/openzeppelin-contracts/releases/tag/v4.8.3", "reference_id": "", "reference_type": "", "scores": [ { "value": "5.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2025-02-05T20:31:10Z/" } ], "url": "https://github.com/OpenZeppelin/openzeppelin-contracts/releases/tag/v4.8.3" }, { "reference_url": "https://github.com/OpenZeppelin/openzeppelin-contracts-upgradeable/commit/58fa0f81c4036f1a3b616fdffad2fd27e5d5ce21", "reference_id": "", "reference_type": "", "scores": [ { "value": "5.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/OpenZeppelin/openzeppelin-contracts-upgradeable/commit/58fa0f81c4036f1a3b616fdffad2fd27e5d5ce21" }, { "reference_url": "https://nvd.nist.gov/vuln/detail/CVE-2023-30541", "reference_id": "", "reference_type": "", "scores": [ { "value": "5.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://nvd.nist.gov/vuln/detail/CVE-2023-30541" }, { "reference_url": "https://github.com/advisories/GHSA-mx2q-35m2-x2rh", "reference_id": "GHSA-mx2q-35m2-x2rh", "reference_type": "", "scores": [], "url": "https://github.com/advisories/GHSA-mx2q-35m2-x2rh" }, { "reference_url": "https://github.com/OpenZeppelin/openzeppelin-contracts/security/advisories/GHSA-mx2q-35m2-x2rh", "reference_id": "GHSA-mx2q-35m2-x2rh", "reference_type": "", "scores": [ { "value": "5.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2025-02-05T20:31:10Z/" } ], "url": "https://github.com/OpenZeppelin/openzeppelin-contracts/security/advisories/GHSA-mx2q-35m2-x2rh" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/64721?format=api", "purl": "pkg:npm/%40openzeppelin/contracts@4.8.3", "is_vulnerable": true, "affected_by_vulnerabilities": [ { "vulnerability": "VCID-mshr-yc9h-jufk" }, { "vulnerability": "VCID-n62w-34wv-rbdn" }, { "vulnerability": "VCID-rgdr-jxdc-hucn" }, { "vulnerability": "VCID-wvaj-hpg7-jbag" } ], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:npm/%2540openzeppelin/contracts@4.8.3" } ], "aliases": [ "CVE-2023-30541", "GHSA-mx2q-35m2-x2rh" ], "risk_score": 3.1, "exploitability": "0.5", "weighted_severity": "6.2", "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-nz22-6jy1-x3bv" }, { "url": "http://public2.vulnerablecode.io/api/vulnerabilities/110503?format=api", "vulnerability_id": "VCID-qt6w-nqmu-57by", "summary": "OpenZeppelin Contracts's SignatureChecker may revert on invalid EIP-1271 signers\n### Impact\n\n`SignatureChecker.isValidSignatureNow` is not expected to revert.
