LG WebOS TV systems are affected by a critical security flaw in the browser-service component that allows unauthorized attackers to bypass authentication and gain complete administrative control.
Disclosed during the TyphoonPWN 2025 LG Category competition—where it won first place—this vulnerability impacts models such as the LG WebOS 43UT8050 and likely extends to other WebOS versions.
