OpenZeppelin Contracts for Cairo is vulnerable to signature validation bypass

OpenZeppelin Contracts for Cairo is a library for secure smart contract development written in Cairo for StarkNet, a decentralized ZK Rollup. `is_valid_eth_signature` is missing a call to `finalize_keccak` after calling `verify_eth_signature`. As a result, any contract using `is_valid_eth_signature` from the account library (such as the `EthAccount` preset) is vulnerable to a malicious sequencer. Specifically, the malicious sequencer would be able to bypass signature validation to impersonate an instance of these accounts. The issue has been patched in 0.6.1.

OpenZeppelin 数据伪造问题漏洞

OpenZeppelin是一个应用软件。一个安全区块链应用的标准。 OpenZeppelin Contracts for Cairo 存在数据伪造问题漏洞，该漏洞源于 is_valid_eth_signature 在调用 verify_eth_signature 后缺少对 finalize_keccak 的调用。
