Detailsinfo

A vulnerability was found in Unitree Robotics Unitree Go2 up to 1.1.11.4. It has been classified as very critical. This affects the function set_volume of the file gpt_thread.py of the component chat_go. The manipulation of the argument value with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability.
