EPSS exploit prediction: 2% (82nd percentile)
Actively exploited: Not listed in CISA KEV
EU (EUVD) id: EUVD-2025-31217
Weakness: CWE-78
Affected product: Unitree G1 Firmware

Description

Multiple robotic products by Unitree sharing a common firmware, including the Go2, G1, H1, and B2 devices, contain a command injection vulnerability. By setting a malicious string when configuring the on-board WiFi via a BLE module of an affected robot, then triggering a restart of the WiFi service, an attacker can ultimately trigger commands to be run as root via the wpa_supplicant_restart.sh shell script. All Unitree models use firmware derived from the same codebase (MIT Cheetah), and the two major forks are the G1 (humanoid) and Go2 (quadruped) branches.
