Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Two critical fixes in the same component address signature verification: recovery ID normalization and address equality check. These are foundational to all Ethereum-signed transactions; a bypass here compromises the entire authentication model.
Auth Bypass: Consensus messages (block announcements, proposals, reset) lacked signature validation entirely, allowing unauthorized block acceptance. This is a critical integrity failure in the v2 consensus path.
Auth Bypass: Validator operations (join/approve/remove/leave) lacked sender-validator checks, allowing unauthorized validator set manipulation. Multiple fixes touch this surface, indicating incomplete enforcement.
