Technical details

A QA build of the Google Cobalt browser engine in the affected firmware exposes the WebDriver server on TCP port 4444 across all interfaces with no authentication required. A network-adjacent attacker can connect and execute arbitrary JavaScript in the browser context, access localStorage containing ACR telemetry, MAC addresses, ad-service credentials and location data, inject persistent UI content, and call the window.hisense native bridge to perform filesystem and system operations.
