CVE-2026-29093 Details
Description
WWBN AVideo is an open source video platform. Prior to version 24.0, the official docker-compose.yml publishes the memcached service on host port 11211 (0.0.0.0:11211) with no authentication, while the Dockerfile configures PHP to store all user sessions in that memcached instance. An attacker who can reach port 11211 can read, modify, or flush session data — enabling session hijacking, admin impersonation, and mass session destruction without any application-level authentication. This issue has been patched in version 24.0.
A vulnerability exists in WWBN AVideo versions prior to 24.0, where the official docker-compose.yml file exposes the memcached service on host port 11211 without authentication. This allows an attacker to access session data stored in memcached, as PHP is configured to use this instance for all user sessions. The exposure enables session hijacking, impersonation of admin users, and mass destruction of session data, all without requiring any application-level authentication.
Users are advised to update to AVideo version 24.0 or later, where this vulnerability has been patched. For those who need to use an earlier version, the memcached port can be bound to localhost only, or SASL authentication can be enabled as a defense-in-depth measure.
