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.
