Upgrade wwbn/avideo to version 29.0 or higher.
Overview
wwbn/avideo is an Audio and Video Platform or simply "A Video Platform".
Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF) via the AVideo endpoint objects/emailAllUsers.json.php allows administrators to send HTML emails to every registered user on the platform. While the endpoint verifies admin session status, it does not validate a CSRF token. Because AVideo sets SameSite=None on session cookies, a cross-origin POST request from an attacker-controlled page will include the admin's session cookie automatically. An attacker who lures an admin to a malicious page can send an arbitrary HTML email to every user on the platform, appearing to originate from the instance's legitimate SMTP address.
The endpoint does not call save() on any ORM object, which means the Referer/Origin domain validation implemented in ObjectYPT::save() is never triggered, leaving CSRF as the only required protection - and it is absent.
