issubscriber false

user_access deny

substatus EXPIRED

serverhost 45

video_name Zatima.S01E01 hk.mp4

Finding: The server sets user_access=deny and issubscriber=false but still returns playingUrl in the same response. Subscription is enforced client-side only — any caller with the expired APK JWT can obtain stream URLs without a subscription. Munowatch CDN (b-cdn.net) serves content with no auth required (direct HTTP Range requests succeed with HTTP 206).
