Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Access Control: Insecure verification of exit events during bridge withdrawal could allow unauthorized token releases. Validating against correct event signatures is critical to prevent access control bypasses.
Access Control: Insufficient validation of caller identities on relayer states and fee structures could permit arbitrary modification of key system configurations if access control roles are bypassed.
Access Control: Bypassing intended caller identity in meta-transactions by relying on direct msg.sender instead of meta-transaction context helpers (like _msgSender()) leads to context-spoofing risks.
