CVE-2026-86728Public exploitNetwork attack vector

Unauthenticated credential disclosure via unguarded EPG serialization

Published Sep 8, 2026 · Updated Sep 8, 2026

Authentication bypass in WWBN AVideo 29.0 and earlier allows remote attackers to read live-stream keys and private EPG schedules. The PlayLists epg.json.php endpoint reads users_id or playlists_id directly and JSON-serializes the resulting EPG object without authentication or the sibling showOnTV filter. Anonymous network access permits sequential identifier enumeration, exposing restricted stream credentials, server identifiers, and full private program schedules.
