Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Signature Bypass: The verification system was vulnerable to a critical signature bypass where validated hashes did not match the actual contents of the VM structure, allowing arbitrary message forging.
Auth Bypass: A critical quorum bypass existed where the signature verification logic failed to check signature index uniqueness, allowing an attacker to reuse a single guardian's signature multiple times to satisfy the quorum requirement.
Auth Bypass: Failing to enforce wrapped token metadata validation in complete_wrapped allowed unauthorized minting via forged or unchecked VAAs.
