Recurring patterns

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

Auth Bypass: The use of a JVM-wide default authenticator for HTTP-based configuration retrieval can leak credentials or cache authorization contexts across separate threads and connection requests. Replacing this with a targeted, per-connection HTTP Basic Authorization header is critical to prevent authorization bypass and privilege leakage.

Auth Bypass: Memcached protocol operations could be queued or executed before the SASL authentication phase officially completes. Enforcing a strict latch-based queue blocking mechanism during initial connection and reconnection prevents unauthorized command execution prior to authentication.
