Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Retrieval of chunks or data via NDN APIs historically bypassed ACLs when requests omitted both referer objects and request paths, or when zonally-originated requests skipped target DEC permission checks. Ensuring strict, target-aware path checks and denying empty or unverified referers is critical.

Auth Bypass: Consensus state queries and block description updates received from OOD nodes on sub-paths lacked cryptographic and consensus verification, allowing unverified state updates to be processed in Hotstuff consensus.

Auth Bypass: Cryptographic operations (signing and verifying objects) bypassed access control checks if the input processor failed to early-verify zone authenticity, map correct privileges (e.g. Call instead of Read/Write), and check system-dec source boundaries.
