Two critical remote code execution vulnerabilities in Unitree G1 EDU robots allow root access via network-adjacent path traversal and BLE proximity. Owners lack verified firmware fixes, leaving devices potentially exposed.

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
The recovered key could then be used to establish the authenticated BLE state required by the Wi-Fi provisioning operations. The chain then reached the Wi-Fi provisioning code. Laflamme documented a buffer overflow there that produced root execution on the Locomotion PC. Laflamme limited his propagation test to two G1 robots in one room. He said in the August 27 disclosure that the cloud authorization fix breaks that exact proof-of-concept flow. Unitree's official product page distinguishes the G1 and G1 EDU as separate models, while broader applicability of the two new vulnerabilities to other Unitree robots remains unconfirmed. The Hacker News has reached out to Unitree to confirm the fixed firmware versions, the affected product scope, and the current remediation status, and will update the story with any response.
