Security researchers have discovered new Bluetooth security flaws that allow hackers to impersonate devices and perform man-in-the-middle attacks.

The vulnerabilities impact all devices with Bluetooth 4.2 through Bluetooth 5.4, including laptops, PCs, smartphones, tablets, and others.

Users can do nothing at the moment to fix the vulnerabilities, and the solution requires device manufacturers to make changes to the security mechanisms used by the technology.

As someone who's relatively tech illiterate, this simply means that a bad actor can see what information is being shared via Bluetooth, right? Like, if I connect to a pair of headphones, they could only receive whatever information my phone sends to the headphones and whatever information the headphones send back?

It means they can impersonate the Bluetooth device connected. Input devices are particularly concerning (keyboards and mice) as well as BT IoT devices which already historically lack good security controls. A lot of vehicles have Bluetooth integrated as well these days.
