CVE-2026-80234Network attack vector

Unauthenticated media file-list disclosure

Published Aug 26, 2026 · Updated Aug 26, 2026

Missing authentication in CAYIN CMS-WS 1.0.25336 and earlier and CMS-SE 11.0.25336 and earlier allows remote attackers to list media files. The affected functionality returns the media-folder inventory without validating the caller's identity or session, but its endpoint and implementation are undisclosed. Network reachability alone is sufficient; exposure is limited to file-list metadata, with no reported access to media contents or modification.
