CVE-2026-90548Network attack vectorHinoki check available

Protected gallery disclosure via unchecked listing endpoint

Published Sep 12, 2026 · Updated Sep 12, 2026

Missing authorization in WWBN AVideo allows remote attackers to list filenames and URLs for password-protected image galleries. The ImageGallery list.json.php endpoint enumerates gallery files without checking authentication or the requesting user's gallery permissions. Network access to the endpoint is sufficient to discover protected file URLs, after which the exposed files can be fetched without authentication.
