Description
WWBN AVideo is an open source video platform. Prior to version 26.0, a Server-Side Request Forgery (SSRF) vulnerability exists in `plugin/Live/standAloneFiles/saveDVR.json.php`. When the AVideo Live plugin is deployed in standalone mode (the intended configuration for this file), the `$_REQUEST['webSiteRootURL']` parameter is used directly to construct a URL that is fetched server-side via `file_get_contents()`. No authentication, origin validation, or URL allowlisting is performed. Version 26.0 contains a patch for the issue.
