Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains an unauthenticated access vulnerability where a QA build of the Google Cobalt browser engine exposes the WebDriver automation server on TCP port 4444 across all network interfaces without any authentication or pairing requirement. A LAN-adjacent attacker can connect to the exposed WebDriver service to execute arbitrary JavaScript, read and exfiltrate sensitive localStorage data including ACR telemetry, MAC addresses, ad-service credentials, and location data, inject persistent content onto the display, and access the window.hisense native bridge to perform filesystem read/write and system-state operations.
