AVideo has an incomplete fix for CVE-2026-33502 (Command Injection)

WWBN AVideo is an open source video platform. In versions up to and including 29.0, an incomplete fix for AVideo's `test.php` adds `escapeshellarg` for wget but leaves the `file_get_contents` and `curl` code paths unsanitized, and the URL validation regex `/^http/` accepts strings like `httpevil[.]com`. Commit 78bccae74634ead68aa6528d631c9ec4fd7aa536 contains an updated fix.
