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.
The issue was patched in 4.7.1.
