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."}],"source":{"advisory":"GHSA-g8x9-7mgh-7cvj","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-g8x9-7mgh-7cvj","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-24T14:54:46.806864Z","id":"CVE-2026-33649","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-24T15:13:47.830Z"}}]}}
