GHSA-qh9x-gcfh-pcrw
OpenZeppelin Contracts's ERC165Checker may revert instead of returning false
Quick fix
GHSA-qh9x-gcfh-pcrw — @openzeppelin/contracts: upgrade to the fixed version with the command below.
npm install @openzeppelin/contracts@4.7.1Details
### Impact
`ERC165Checker.supportsInterface` is designed to always successfully return a boolean, and under no circumstance 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-165 as expected, specifically if it returns a value other than 0 or 1.
The contracts that may be affected are those that use `ERC165Checker` to check for support for an interface and then handle the lack of support in a way other than reverting.
### Patches
The issue was patched in 4.7.1.
