Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Several critical smart contracts utilized improper initialization modifiers (such as 'reinitializer(2)' instead of 'initializer'), exposing them to unauthorized re-initialization and takeover of contract states.
Cryptographic Vulnerability: A logical operator error within the SGX PEM certificate parsing library allowed certificates with invalid ASN.1 date formats to be accepted, undermining the validity of SGX-based verifications.
Auth Bypass: The signal service allowed proof validation bypasses by processing empty proofs and maintaining legacy zero-proof execution paths.
