Recurring patterns

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

Auth Bypass: Incoming message replication events and database writes in the storage layer historically bypassed cryptographic signature verification, allowing potential message spoofing or unauthorized database writes before processing. Shifting and enforcing this verification at the storage backend boundary is critical.
Improper Certificate Validation: Flaws in peer certificate generation and validation, including misconfigured key usages (cRLSign/keyCertSign) and incorrect Subject Alternative Name formatting, risked allowing unauthorized nodes to spoof onion addresses or act as rogue Certificate Authorities within the network.
Auth Bypass: Local host socket interfaces lacked proper connection token and origin validation, exposing internal APIs and control channels to potential local-origin bypasses and cross-site WebSocket attacks.
