Attackers with upload permission can retrieve an administrator's video_id_hash by omitting the videos_id parameter, then use that hash in an unauthenticated request to gain administrative session access and modify system configuration.","published":"2026-08-22T13:16:38.977","modified":"2026-08-22T13:16:38.977","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-q32p-rw3q-8x3r"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/avideo-authentication-bypass-via-unkeyed-video-hash-disclosure"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-22T13:16:38.977"}}
