How to fix?

Upgrade @openzeppelin/contracts-upgradeable to version 4.7.1 or higher.

Overview

@openzeppelin/contracts-upgradeable is a Secure Smart Contract library for Solidity.

Affected versions of this package are vulnerable to Information Exposure. 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.
