CVE-2026-90536Network attack vectorHinoki check available

Owner ID disclosure via unauthorized adsInfo requests

Published Sep 12, 2026 · Updated Sep 12, 2026

Missing authorization in the adsInfo API in WWBN AVideo allows remote attackers to read password-protected video owner IDs. The endpoint accepts a videos_id parameter and returns the selected video's owner ID and personalized ad creative URLs without authentication or a permission check. Network access to the API and knowledge of a video ID are sufficient; the disclosed identifiers and ad URLs do not grant access to the protected video itself.
