{"id":"CVE-2026-33649","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-33649","generatedAt":"2026-10-28T10:39:59.563Z","title":"The endpoint has no CSRF token validation, and the application explicitly sets `session.cookie_samesite=None` on session cookies.","description":"WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `plugin/Permissions/setPermission.json.php` endpoint accepts GET parameters for a state-changing operation that modifies user group permissions. The endpoint has no CSRF token validation, and the application explicitly sets `session.cookie_samesite=None` on session cookies. This allows an unauthenticated attacker to craft a page with `<img>` tags that, when visited by an admin, silently grant arbitrary permissions to the attacker's user group — escalating the attacker to near-admin access. As of time of publication, no known patched versions are available.","published":"2026-03-23T19:16:41.000Z","lastModified":"2026-06-17T10:37:52.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-352"],"affected":["wwbn/avideo"],"epss":{"score":0.00175,"percentile":0.07008,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.18%).
