56 high-severity fixes in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Conditional validation parameters and optional signature flags previously allowed critical block components (RANDAO reveals, attestations, and proposer slashings) to bypass cryptographic verification entirely.
Auth Bypass: Multiple path-mismatch and interceptor logic bugs in the validator and keymanager gRPC/REST APIs historically allowed unauthenticated access to sensitive management endpoints.
Signature Validation Bypass: Decompression routine vulnerabilities allowed public keys and signatures that did not belong to the correct BLS subgroup to bypass validation, undermining the entire cryptographic consensus mechanism.
