EPSS · scored 2026-10-28

Tesla Model X vehicles before 2020-11-23 do not perform certificate validation during an attempt to pair a new key fob with the body control module (BCM). This allows an attacker (who is inside a vehicle, or is otherwise able to send data over the CAN bus) to start and drive the vehicle with a spoofed key fob.
