Solady lacks extcodesize validation on implementation in ERC4337Factory_CVE-2025-53638

6.9 / 10

MEDIUM

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

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.
