Voting signature malleability of EVM's ecrecover in castVoteBySig

Lines of code Vulnerability details Proof of Concept EVM's ecrecover is susceptible to signature malleability which allows replay attacks, but that is mitigated here by doing receipt.hasVoted = true;. However, if any of the application logic changes, it might make signature malleability a risk fo...

GHSA-4H98-2769-GH6H OpenZeppelin Contracts vulnerable to ECDSA signature malleability

Impact The functions ECDSA.recover and ECDSA.tryRecover are vulnerable to a kind of signature malleability due to accepting EIP-2098 compact signatures in addition to the traditional 65 byte signature format. This is only an issue for the functions that take a single bytes argument, and not the...

Authorization Bypass

OpenZeppelin contracts are vulnerable to authorization bypass. The vulnerability is due to functions ECDSA.recover and ECDSA.tryRecover accepting EIP-2098 and 65-byte signatures. Affected contracts have signature reuse or replay protection, implemented by marking the signature as used rather than...

Direct usage of ecrecover allows signature malleability

Lines of code Vulnerability details Impact The permit function of ERC20Permit calls the Solidity ecrecover function directly to verify the given signatures. However, the ecrecover EVM opcode allows malleable non-unique signatures and thus is susceptible to replay attacks. This can leads to permit...
