Unitree Go2, G1, H1, and B2 devices through 2025-09-20 allow root OS command injection via the hostapd_restart.sh wifi_ssid or wifi_pass parameter (within restart_wifi_ap and restart_wifi_sta).

Unitree Go2, G1, H1, and B2 devices through 2025-09-20 decrypt BLE packet data by using the df98b715d5c6ed2b25817b6f2554124a key and the 2841ae97419c2973296a0d4bdfe19a4f IV.

Unitree Go2, G1, H1, and B2 devices through 2025-09-20 accept any handshake secret with the unitree substring.

Unitree Multiple Robotic Products Command Injection

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.
