{"id":"CVE-2025-53638","state":"PUBLISHED","title":"Solady lacks extcodesize validation on implementation in ERC4337Factory","description":"Solady is software that provides Solidity snippets with APIs. Starting in version 0.0.125 and prior to version 0.1.24, when an account is deployed via a proxy, using regular Solidity to call its initialization function may result in a silent failure, if the initialization function does not return a `bool` or some other return data.  This is because regular Solidity uses `extcodesize(proxy)` to decide if call succeeds. This is insufficient in the case when the proxy points to an empty implementation. Users should upgrade to Solady v0.1.24 or later to receive a patch. Deploy any affected implementations and their factories on new EVM chains as soon as possible.","publishedAt":"2025-07-17T17:54:40.666Z","updatedAt":"2025-07-17T20:22:29.683Z","severity":{"score":6.9,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["Vectorized solady"],"affected":[{"vendor":"Vectorized","product":"solady","versions":[{"version":">= 0.0.125, < 0.1.24","status":"affected"}]}],"references":["https://github.com/Vectorized/solady/security/advisories/GHSA-8xvx-4mvg-m9v8","https://github.com/Vectorized/solady/releases/tag/v0.1.24"],"weaknesses":["CWE-754"],"ingestedAt":"2026-10-29T20:09:31.862Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/53xxx/CVE-2025-53638.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-53638","state":"PUBLISHED","datePublished":"2025-07-17T17:54:40.666Z","dateUpdated":"2025-07-17T20:22:29.683Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-07-07T14:20:38.390Z"},"containers":{"cna":{"title":"Solady lacks extcodesize validation on implementation in ERC4337Factory","descriptions":[{"lang":"en","value":"Solady is software that provides Solidity snippets with APIs.
