AVideo has SSRF in BulkEmbed Thumbnail Fetch that Allows Reading Internal Network Resources
CVE-2026-33294
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.
