CVE-2026-88875Network attack vector

Authenticated owner-data disclosure via missing ownership check

Published Sep 10, 2026 · Updated Sep 10, 2026

Information disclosure in WWBN AVideo allows remote authenticated users to read another video owner's account data through the video API. API::get_api_video() removes sensitive joined user fields only for callers who are unauthenticated and lack a valid API secret, without comparing the requester ID to the video's users_id. A low-privilege account can retrieve another owner's email address, account name, and privilege flags; no integrity or service impact is reported.
