CVE-2026-82602Public exploitNetwork attack vectorHinoki check available

Paywalled media URL disclosure via omitted authorization enforcement

Published Aug 31, 2026 · Updated Aug 31, 2026

Information disclosure in SeaCMS 13.0 through 13.6 allows remote attackers to obtain paywalled media URLs through ass.php. The endpoint queries playback and payment metadata, calculates isauth, then returns the complete video URL array even when isauth is n. No authentication or user interaction is required; the consequence is limited to protected playback-location disclosure, with no reported ability to modify media or configuration.
