Name of the Vulnerable Software and Affected Versions OpenZeppelin Contracts versions 4.0.0 through 4.9.3

Description OpenZeppelin Contracts is a library for secure smart contract development. Contracts using ERC2771Context along with a custom trusted forwarder may see msgSender return address(0) in calls that originate from the forwarder with calldata shorter than 20 bytes. This combination of circumstances does not appear to be common, in particular it is not the case for MinimalForwarder from OpenZeppelin Contracts, or any deployed forwarder the team is aware of, given that the signer address is appended to all calls that originate from these forwarders.

Recommendations For versions prior to 4.9.3, update to version 4.9.3 to resolve the issue. As a temporary workaround, consider restricting the use of custom trusted forwarders with ERC2771Context until the update is applied. Avoid using calldata shorter than 20 bytes in calls that originate from custom trusted forwarders until the issue is resolved.
