Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the CDN plugin endpoints `plugin/CDN/status.json.php` and `plugin/CDN/disable.json.php` use key-based authentication with an empty string default key. When the CDN plugin is enabled but the key has not been configured (the default state), the key validation check is completely bypassed, allowing any unauthenticated attacker to modify the full CDN configuration — including CDN URLs, storage credentials, and the authentication key itself — via mass-assignment through the `par` request parameter. Commit adeff0a31ba04a56f411eef256139fd7ed7d4310 contains a patch.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-306

A sensitive function is reachable with no authentication at all, so anyone who finds the endpoint can use it. These are routinely discovered by automated scanning. The fix is to require and enforce authentication on every privileged path, with no exceptions left open.

Recommended fix Moderate confidence

Version 26.1 or later (any release containing commit adeff0a31ba04a56f411eef256139fd7ed7d4310)

  1. 1. Backup your current AVideo installation and database before making any changes
  2. 2. Navigate to the official AVideo releases page or your installation's admin panel
  3. 3. Check for a version newer than 26.0 that includes the security patch (commit adeff0a31ba04a56f411eef256139fd7ed7d4310)
  4. 4. Download the latest stable release
  5. 5. Update your AVideo installation to the fixed version
  6. 6. After upgrading, log in to the admin panel and navigate to the CDN plugin settings
  7. 7. Configure a non-empty, strong authentication key for the CDN plugin
  8. 8. Verify the CDN plugin endpoints now require authentication
Caveat Review release notes for any breaking changes between 26.0 and the target version; standard practice is to test in staging first
