A LAN-adjacent attacker can exploit this to inject key events, change volume, switch input sources, enumerate inputs, launch arbitrary installed applications, and monitor pairing activity, posing a significant risk in hotel deployments where untrusted LAN access is common.https://vulnfeed.org/cve/CVE-2026-123997/https://vulnfeed.org/cve/CVE-2026-123997/Fri, 06 Nov 2026 18:59:03 +0000Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains an unauthenticated denial-of-service vulnerability in the UPnP/DLNA AVTransport SOAP service that allows LAN-adjacent attackers to freeze the entire television software layer by sending a crafted SetAVTransportURI request on TCP port 38400. Attackers can exploit this flaw without credentials to render the device completely unresponsive to remote control or front-panel input, requiring a physical power cycle to restore functionality.https://vulnfeed.org/cve/CVE-2026-123993/https://vulnfeed.org/cve/CVE-2026-123993/Fri, 06 Nov 2026 18:52:34 +0000Hisense 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.
