Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-77.
Summary
Unitree Go2 up to and including 1.1.11.4 contains an OS command injection flaw (CWE-78) in the set_volume function of the chat_go component. The function does not neutralize special characters in its Value argument, so attacker-supplied input reaches an operating system command. A remote attacker with no privileges can run commands on the device, and the CVSS 4.0 score is 9.4. CISA's SSVC assessment lists exploitation as proof of concept.

Description from the CNA
A security vulnerability has been detected in Unitree Robotics Unitree Go2 up to 1.1.11.4. The impacted element is the function set_volume of the file gpt_thread.py of the component chat_go. Such manipulation of the argument Value leads to os command injection. The attack can be launched remotely. Upgrading to version 1.1.11.5 is sufficient to resolve this issue. You should upgrade the affected component. The vendor confirmed early: "Submission 990502 corresponds to our internal ticket #474 (Go2 chat_go set_volume OS command injection, CWE-78)."
