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 29.0 and below, the `isSSRFSafeURL()` function in `objects/functions.php` contains a same-domain shortcircuit (lines 4290-4296) that allows any URL whose hostname matches `webSiteRootURL` to bypass all SSRF protections. Because the check compares only the hostname and ignores the port, an attacker can reach arbitrary ports on the AVideo server by using the site's public hostname with a non-standard port. The response body is saved to a web-accessible path, enabling full exfiltration. Commit a0156a6398362086390d949190f9d52a823000ba fixes the issue.

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

Version greater than 29.0 (containing commit a0156a6398362086390d949190f9d52a823000ba)

  1. 1. Check the current AVideo installation version by examining the version file or admin panel.
  2. 2. Obtain the fixed version that includes commit a0156a6398362086390d949190f9d52a823000ba - this should be a version newer than 29.0.
  3. 3. Before upgrading, backup the entire AVideo installation directory and database.
  4. 4. Download the updated AVideo release from the official GitHub repository.
  5. 5. Deploy the new version, ensuring the `objects/functions.php` file contains the patched `isSSRFSafeURL()` function.
  6. 6. Verify the fix by testing that the SSRF protection now properly blocks same-hostname URLs with non-standard ports.
  7. 7. Review other SSRF-related functions in the same file to ensure no similar bypasses exist.
Caveat Check release notes for version >29.0 for any breaking changes; minor version upgrades in AVideo typically have low risk
