CVE-2026-86726Public exploitNetwork attack vector

Cross-account stream-key disclosure via missing ownership filter

Published Sep 8, 2026 · Updated Sep 8, 2026

Information disclosure in AVideo 29.0 and earlier allows remote authenticated users to read other streamers' source keys and identities. The restreamsActive.json.php endpoint calls getRestreamsRuning(), extracts each FFmpeg process's source key, enriches every record with identity fields, and serializes the full unfiltered set without a users_id ownership check. Any account with streaming capability can enumerate active-restream credentials across all accounts without administrator access or user interaction.
