2023-08-11漏洞描述
OpenZeppelin Contracts is a library for secure smart contract development. Starting in version 4.0.0 and prior to version 4.9.3, 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. The problem has been patched in v4.9.3.解决建议
"将组件 @openzeppelin/contracts 升级至 4.9.3 及以上版本""将组件 @openzeppelin/contracts-upgradeable 升级至 4.9.3 及以上版本"受影响软件情况
