CVE-2025-55971Public exploit

Unauthenticated SSRF via unrestricted SetAVTransportURI retrieval

Published Oct 3, 2025 · Updated Oct 3, 2025

Blind SSRF in TCL 65C655 Smart TV firmware V8-R75PT01-LF1V269.001116 allows remote attackers to send requests via UPnP. The unauthenticated AVTransport:1 SetAVTransportURI handler accepts an attacker-controlled media URI and retrieves it without restricting the destination. Reachability requires access to the TV's local network service on a restart-dependent TCP port in the 16XXX range; the device can probe loopback, LAN, or Internet services, but responses remain blind.
