Versions 4.1.0 until 4.7.1 are vulnerable to the SignatureChecker reverting. `SignatureChecker.isValidSignatureNow` is not expected to revert. However, an incorrect assumption about Solidity 0.8's `abi.decode` allows some cases to revert, given a target contract that doesn't implement EIP-1271 as expected. The contracts that may be affected are those that use `SignatureChecker` to check the validity of a signature and handle invalid signatures in a way other than reverting. The issue was patched in version 4.7.1.\n\ud83d\udccf Published: 2022-07-21T13:55:11.000Z\n\ud83d\udccf Modified: 2025-04-23T17:57:33.239Z\n\ud83d\udd17 References:\n1. https://github.com/OpenZeppelin/openzeppelin-contracts/security/advisories/GHSA-4g63-c64m-25w9\n2. https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3552", "creation_timestamp": "2025-04-23T18:05:38.000000Z"}
