Summary

In WWBN AVideo up to version 26.0, the file objects/aVideoEncoderReceiveImage.json.php allowed an authenticated uploader to fetch attacker-controlled same-origin /videos/... URLs, bypass traversal scrubbing, and expose server-local files through the GIF poster storage path. The vulnerable GIF branch could be abused to read local files such as /etc/passwd or application source files and republish those bytes through a normal public GIF media URL.

Risk Assessment

An authenticated attacker can read arbitrary local files on the server, including sensitive system data and application source code, by manipulating GIF requests.

Recommendation

Update AVideo to the latest version that includes a fix for this vulnerability.
