CVE-2026-34364
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the categories.json.php endpoint, which serves the category listing API, fails to enforce user group-based access controls on categories. In the default request path (no ?user= parameter), user group filtering is entirely skipped, exposing all non-private categories including those restricted to specific user groups. When the ?user= parameter is supplied, a type confusion bug causes the filter to use the admin user's (user_id=1) group memberships instead of the current user's, rendering the filter ineffective. Commit 6e8a673eed07be5628d0b60fbfabd171f3ce74c9 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.

The impact is confined to the system where the vulnerability exists. There is a low impact on the confidentiality of the information.
