EPSS

• CVE-2026-29093: 0.54% estimated exploitation activity in the next 30 days; percentile 45.50 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary 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. Severity High (CVSS 3.1: 8.1) CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H - Attack Vector: Network — docker-compose.yml binds memcached to 0.0.0.0:11211 on the host - Attack Complexity: High — exploitation requires port 11211 to be network-reachable, which depends on external firewall/security group configuration beyond the attacker's control - Privileges Required: None — memcached has no authentication mechanism enabled - User Interaction: None - Scope: Unchanged — impact is to the AVideo application's session management - Confidentiality Impact: High — session…

# Patch Next advisory brief: CVE-2026-29093

Advisory: AVideo: Unauthenticated PHP session store exposed to host network via published memcached port
IDs: CVE-2026-29093, GHSA-xxpw-32hf-q8v9
Record: https://patchnext.com/advisories/cve-2026-29093 (revision 1, source checked 26 Oct 2026, 14:38 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist wwbn/avideo: affected <= 21.0

## Suggested inspection (read-only)
- Packagist wwbn/avideo: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on wwbn/avideo.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-xxpw-32hf-q8v9 (GitHub-reviewed advisory GHSA-xxpw-32hf-q8v9 lists affected ranges: Packagist wwbn/avideo >=0 <=21.0)
