WWBN AVideo is an open source video platform. In versions 29.0 and prior, multiple AVideo JSON endpoints under accept state-changing requests via / 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 ( ), post a comment authored by the victim on any video, with attacker-chosen text ( ), and/or delete assets from any category ( ) when the victim has category management rights. Each endpoint is reachable from a browser via a simple tag or form submission, so exploitation only requires the victim to load an attacker-controlled HTML resource. Commit 7aaad601bd9cd7b993ba0ee1b1bea6c32ee7b77c contains a fix.
