On Tuesday, security firm Bitdefender published security research revealing four different software bugs impacting LG’s WebOS TV operating system. The bugs, which affect about 91,000 devices worldwide, could allow a bad actor to gain a number of invasive privileges, including the ability to get root access to an impacted device. Researchers write that the bugs — which impact WebOS versions 4 through 7 — could hypothetically allow a hacker to add a new user to the device, inject their own code into it, and thus “fully take over” the TV. Bitdefender originally alerted LG to these issues in November. Gizmodo reached out to LG for comment and will update this story if it responds.
