Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Authentication Bypass: Peer transport and swarm setup previously failed to cryptographically authenticate peer sessions, allowing unauthenticated connections. Security-critical flows must enforce signed handshake validation during transport initialization.
Auth Bypass: Bypassing verification routines for alternative or unimplemented signers allowed invalid payloads to slip through. Implementing unconditional default verification for all incoming protocol messages is required.
Authorization Bypass: Insufficient validation in the extension registry dispatch routine allowed capability abuse and DID spoofing. Loose RPC and message boundaries must be secured with strict capability separation.
