Two Unitree G1 EDU Humanoid Robot Flaws Enable Root RCE, One Starts Over Bluetooth

Vulnerability / IoT Security
Security researcher Olivier Laflamme has disclosed two independent root remote code execution (RCE) chains affecting the Unitree G1 EDU , including a Bluetooth Low Energy (BLE) path that can reach root on the robot's Locomotion PC. The flaws are tracked as CVE-2026-76639 and CVE-2026-76640 , with the first involving a network-adjacent path through chat_go and bashrunner and the second beginning from BLE proximity. An exact fixed firmware release has not been verified in any accessible Unitree guidance, leaving G1 EDU owners without a confirmed release target for either vulnerability. Laflamme said Unitree patched the cloud account-to-robot ownership check in July 2026, closing the cross-owner arbitrary-G1 path. As of the August 27 disclosure, a G1 owner could still use an account bound to their own robot to recover its Advanced Encryption Standard (AES) key. The underlying BLE issues, a write to 0xFFE2 that does not require pairing and the BSS buffer overflow,...
