The record

Multiple AVideo JSON endpoints under `objects/` accept state-changing requests via `$_REQUEST`/`$_GET` and persist changes tied to the caller's session user, without any anti-CSRF token, origin check, or referer check. A malicious page visited by a logged-in victim can silently: 1. Cast/flip the victim's like/dislike on any comment (`objects/comments_like.json.php`). 2. Post a comment authored by the victim on any video, with attacker-chosen text (`objects/commentAddNew.json.php`). 3. Delete assets from any category (`objects/categoryDeleteAssets.json.php`) when the victim has category management rights. Each endpoint is reachable from a browser via a simple `<img src="…">` tag or form submission, so exploitation only requires the victim to load an attacker-controlled HTML resource.
