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, an unauthenticated server-side request forgery vulnerability in `plugin/Live/test.php` allows any remote user to make the AVideo server send HTTP requests to arbitrary URLs. This can be used to probe localhost/internal services and, when reachable, access internal HTTP resources or cloud metadata endpoints. Commit 1e6cf03e93b5a5318204b010ea28440b0d9a5ab3 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.

dbcve analysis
How this class of weakness works · CWE-918

The server can be induced to make requests to a URL an attacker controls, turning it into a proxy into internal networks and cloud metadata services. It's especially dangerous behind a trusted network boundary. The fix is strict allow-listing of destinations and blocking access to internal address ranges.

Recommended fix Moderate confidence

Upgrade to AVideo version 26.1 or later (the first version containing commit 1e6cf03e93b5a5318204b010ea28440b0d9a5ab3)

  1. 1. Navigate to the AVideo installation directory on the server
  2. 2. Ensure you have a backup of the current installation
  3. 3. Check the current version by examining version.php or similar version file in the AVideo installation
  4. 4. Fetch the latest stable release from the official AVideo repository at https://github.com/WWBN/AVideo
  5. 5. Review release notes to confirm version 26.1 or later includes the SSRF fix from commit 1e6cf03e93b5a5318204b010ea28440b0d9a5ab3
  6. 6. Upgrade to the fixed version by downloading and extracting the new release, then overwriting files while preserving configuration
  7. 7. Alternatively, apply the specific patch by examining commit 1e6cf03e93b5a5318204b010ea28440b0d9a5ab3 to understand the code changes and manually apply them to plugin/Live/test.php
  8. 8. After upgrade or patch application, verify the fix by checking that plugin/Live/test.php no longer accepts arbitrary URLs without authentication
Caveat Minor version upgrade should have minimal breaking changes; always test in staging first
