CVE-2026-115995

Unitree Robotics Unitree Go2 chat_go gpt_thread.py set_volume os command injection

Published Oct 24, 2026 CVSS 4.0 · 9.4 Critical EPSS 1.4% KEV · Not listed
Description
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)."

Analysis

AI-generated

Technical impact

A vulnerability in the Unitree Go2 firmware allows an attacker to manipulate the volume parameter within the chat_go's gpt_thread.py component. By providing a crafted input, an adversary can execute arbitrary operating‑system commands, a flaw enumerated as CWE‑77 and CWE‑78. This injection can lead to Remote Code Execution against the device.

Affected Systems

Devices manufactured by Unitree Robotics, specifically the Unitree Go2, are affected when running firmware versions up to 1.1.11.4. The issue is corrected in firmware 1.1.11.5 and later. The flaw resides in the chat_go component of the robot's control system.

Risk and Exploitability

The flaw receives a CVSS score of 9.4, indicating critical severity. The EPSS score is 1%, and the vulnerability is not listed in CISA's KEV catalog, but the remote attack vector and lack of requirement for local access make exploitation practical over the network. An attacker who can reach the chat_go interface remotely can inject and execute commands on the robot's host operating system.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update the Unitree Go2 firmware to version 1.1.11.5 or later.
  • If firmware upgrade is not immediately possible, disable remote access to the chat_go interface or enforce strong authentication to prevent unauthenticated injection attempts.
  • Configure network firewall rules or segmentation so that only trusted internal networks can initiate requests against the Unitree Go2's chat_go component.
