Vulnerability description

DayBreach CVE AI Research

CVE-2026-40928 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

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.
