Recurring patterns

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

Auth Bypass: The Kademlia DHT engine accepted unvalidated records lacking a namespace prefix, allowing malicious peers to inject arbitrary data into the node's datastore. Developers must enforce strict validators and namespace constraints on any record insertion path.

Auth Bypass: The pubsub implementation previously emitted and forwarded incoming messages without enforcing strict signature verification, leaving the network vulnerable to message spoofing and forgery. Consistent verification on all message forwarding and consumption paths is mandatory.

Cryptographic Weakness: WebCrypto-based AES-CTR encryption in browser environments suffered from counter block reuse across encrypt/decrypt operations, breaking confidentiality. Secure streaming primitives must be consistently used over raw browser APIs.
