Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Accepting zero private keys and identity public keys violates RFC 9497, potentially allowing authentication bypasses via weak parameters during deserialization.
Cryptographic Issue: Failing to reject BLS signatures decoding to the identity point permits signature validation bypasses and signature forgery.
Signature Forgery: Accepting duplicated messages during BLS aggregate signature verification enables rogue-key or signature forgery attacks.
