Name of the Vulnerable Software and Affected Versions OpenZeppelin Contracts versions prior to 4.7.2

Description The target contract of an EIP-165 supportsInterface query can cause unbounded gas consumption by returning a lot of data, while it is generally assumed that this operation has a bounded cost.

Recommendations For versions prior to 4.7.2, upgrade to version 4.7.2 to resolve the issue. As a temporary workaround, consider restricting the amount of data returned by the target contract of an EIP-165 supportsInterface query to prevent unbounded gas consumption.
