CVE-2026-33294 is a medium-severity flaw (CVSS 5.0) affecting avideo. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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
