The record

The `isSSRFSafeURL()` function in `objects/functions.php` contains a same-domain shortcircuit (lines 4290-4296) that allows any URL whose hostname matches `webSiteRootURL` to bypass all SSRF protections. Because the check compares only the hostname and ignores the port, an attacker can reach arbitrary ports on the AVideo server by using the site's public hostname with a non-standard port. The response body is saved to a web-accessible path, enabling full exfiltration.
