CVE-2026-40928
No affected components available
WWBN AVideo is an open source video platform. In versions 29.0 and prior, 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 cast/flip the victim's like/dislike on any comment (objects/comments_like.json.php), post a comment authored by the victim on any video, with attacker-chosen text (objects/commentAddNew.json.php), and/or 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. Commit 7aaad601bd9cd7b993ba0ee1b1bea6c32ee7b77c contains a fix.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. The attacker needs the user to perform some action, like clicking a link. The impact is confined to the system where the vulnerability exists. There is a low impact on the integrity of the data. There is a low impact on the availability of the system.
