Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Attackers could bypass designated routing mechanics and hijack relay calls because the system failed to enforce that the actual transaction sender matched the designated relay worker encoded in the signed payload.
Signature Malleability: The omission of chainId validation within the EIP712 domain separator allowed valid transaction signatures from one network to be replayed maliciously on another.
Denial of Service: Relayers could be subjected to excessive gas-draining or griefing attacks because the system lacked constraints on paymaster acceptance budgets and calls to external gas estimators.
