Unitree Robotics

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 accept any handshake secret with the unitree substring.

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

Since the encryption algorithm used to protect firmware updates is itself encrypted using key material available to an attacker (or anyone paying attention), the firmware updates may be altered by an unauthorized user, and then trusted by a Unitree product, such as the Unitree Go2 and other models. This issue appears to affect all of Unitree’s current offerings as of February 26, 2026, and so should be considered a vulnerability in both the firmware generation and extraction processes. At the time of this release, there is no publicly-documented mechanism to subvert the update process and insert poisoned firmware packages without the equipment owner’s knowledge.

Unitree Go2 firmware versions 1.1.7 through 1.1.11, when used with the Unitree Go2 Android application (com.unitree.doggo2), are vulnerable to remote code execution due to missing integrity protection and validation of user-created programmes. The Android application stores programs in a local SQLite database (unitree_go2.db, table dog_programme) and transmits the programme_text content, including the pyCode field, to the robot. The robot's actuator_manager.py executes the supplied Python as root without integrity verification or content validation. An attacker with local access to the Android device can tamper with the stored programme record to inject arbitrary Python that executes when the user triggers the program via a controller keybinding, and the malicious binding persists across reboots. Additionally, a malicious program shared through the application's community marketplace can result in arbitrary code execution on any robot that imports and runs it.

Unitree Go2 firmware versions V1.1.7 through V1.1.9 and V1.1.11 (EDU) do not implement DDS authentication or authorization for the Eclipse CycloneDDS topic rt/api/programming_actuator/request handled by actuator_manager.py. A network-adjacent, unauthenticated attacker can join DDS domain 0 and publish a crafted message (api_id=1002) containing arbitrary Python, which the robot writes to disk under /unitree/etc/programming/ and binds to a physical controller keybinding. When the keybinding is pressed, the code executes as root and the binding persists across reboots.

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.

A vulnerability has been found in Tenda G1 16.01.7.8(3660). Affected by this issue is the function check_upload_file of the component Firmware Update Handler. The manipulation leads to insufficient verification of data authenticity. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used.

Lack of authentication vulnerability. An unauthenticated local user is able to see through the cameras using the web server due to the lack of any form of authentication.

Authentication bypass vulnerability, the exploitation of which could allow a local attacker to perform a Man-in-the-Middle (MITM) attack on the robot's camera video stream. In addition, if a MITM attack is carried out, it is possible to consume the robot's resources, which could lead to a denial-of-service (DOS) condition.

Using off-the-shelf commodity hardware, the Unitree Go 1 robotics platform version H0.1.7 and H0.1.9 (using firmware version 0.1.35) can be powered down by an attacker within normal RF range without authentication. Other versions may be affected, such as the A1.
