CVE-2026-29093Public exploitNetwork attack vector

Session hijacking via exposed unauthenticated memcached store

Published Mar 6, 2026 · Updated Mar 6, 2026

Improper authentication in WWBN AVideo before 24.0 allows remote attackers to hijack sessions via an exposed memcached service. The official docker-compose.yml publishes port 11211 on all host interfaces without SASL, while the Dockerfile directs PHP session storage to that memcached instance. Network reachability to port 11211 is sufficient to read or rewrite session data for admin impersonation or flush the cache to force mass logout.
