Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Access Control: Multiple fixes target unauthorized initialization, proxy upgrades, and ownership changes, indicating a systemic weakness in privileged-state transitions.
Signature Verification: Critical flaws in signature counting and required-signature checks allowed insufficient signatures to pass; also malleability and replay issues.
Access Control: Unauthorized token claims, relayTokens, receiver misdirection, and block-reward contract substitution show gaps in bridge-specific access control.
