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...

Malicious callers can replay disputes

Lines of code Vulnerability details Unlike some of the other signature based operations in the Rigor system, dispute signatures do not include a nonce and are vulnerable to replay attacks. This is similar to my finding in 339, but lower severity, since it is more of a spamming/griefing vector...

Possible signature replay in updateTaskHash() and updateProjectHash() function

Lines of code Vulnerability details Impact In updateProjectHash function, the data encoded only hash and nonce value but not the projectAddress. In case builder had 2 or more projects, the signature that builder used in updateProjectHash can also be used in other projects by attackers. bytes memo...
