CVE-2026-123994
Hisense VIDAA Smart TV DIAL Service Unauthenticated Access
Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains an unauthenticated access vulnerability in the DIAL (Discovery and Launch) service on TCP port 56789, which accepts control requests from any LAN-adjacent device without authentication, pairing, or user notification. Attackers can query running application states, enumerate installed applications via HTTP response codes, terminate active sessions with a DELETE request, and launch applications or bypass YouTube's Origin check by spoofing the Origin header to disclose viewing activity and subscriptions or disrupt device functionality.
