Unitree G1 Humanoid Robot Flaws Allow Unauthenticated Root RCE Over Bluetooth

Gbhackers •Divya • August 28, 2026

Security researcher Boschko has revealed two vulnerabilities in Unitree’s G1 humanoid robot that can be exploited to achieve unauthenticated remote code execution (RCE) from nearby devices via Bluetooth Low Energy (BLE). This research, referred to as UniBLEed, indicates that the attack can compromise the robot’s Locomotion PC, the component responsible for essential functions, without requiring […]

Critical RCE Flaws Discovered in Unitree G1 EDU Robot Security researcher Olivier Laflamme disclosed two critical root remote code execution (RCE) vulnerabilities in the Unitree G1 EDU robot, tracked as CVE-2026-76639 and CVE-2026-76640. The first vulnerability allows RCE through a network-adjacent path involving chat_go and bashrunner, while the second exploits Bluetooth Low Energy (BLE) for unauthenticated access. These flaws enable attackers to gain root access to the robot's Locomotion PC, which is crucial for its operation. A previously patched authorization gap in Unitree's cloud service has been addressed, but no confirmed firmware fix for the G1 EDU has been released as of August 27, 2026. The potential impact on other Unitree robot models is still unverified, leaving users vulnerable. The vulnerabilities were made public on August 27, 2026, with proof-of-concept code available since August 25, 2026. 8 sources 65
