CVE-2025-53638 – Solady Silent Failure in Proxy Initialization Vulnerability

CVE ID : CVE-2025-53638

Published : July 17, 2025, 6:15 p.m. | 26 minutes ago

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.

Severity: 0.0 | NA
