CVE-2026-123995

Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains an input validation vulnerability in the UPnP/DLNA AVTransport SOAP service that allows a LAN-adjacent attacker to inject arbitrary URIs via the CurrentURI field of SetAVTransportURI without validating the scheme, host, or media legitimacy. Attackers can supply schemes such as http://, file:///data/misc/wifi/, rtsp://, or smb:// to have the TV fetch and render attacker-controlled content after a one-time DLNA pairing, enabling phishing pages, fake firmware prompts, and fake emergency alerts to be displayed, with subsequent commands executing silently.
