CVE-2026-33294 Details
Description
WWBN AVideo is an open source video platform. Prior to version 26.0, the BulkEmbed plugin's save endpoint (`plugin/BulkEmbed/save.json.php`) fetches user-supplied thumbnail URLs via `url_get_contents()` without SSRF protection. Unlike all six other URL-fetching endpoints in AVideo that were hardened with `isSSRFSafeURL()`, this code path was missed. An authenticated attacker can force the server to make HTTP requests to internal network resources and retrieve the responses by viewing the saved video thumbnail. Version 26.0 fixes the issue.
A server-side request forgery (SSRF) vulnerability has been identified in the BulkEmbed plugin for WWBN AVideo, affecting versions through 25.0. The vulnerability arises because the plugin's save endpoint fetches user-provided thumbnail URLs using 'url_get_contents()' without proper SSRF protection. This oversight allows authenticated attackers to manipulate the server into making HTTP requests to internal network resources, potentially exfiltrating sensitive data. The issue has been addressed in version 26.0.
Users can update to WWBN AVideo version 26.0 or later, where this vulnerability has been fixed.
