## Summary

The Unitree Go2 robot's chat_go component, which handles its WebSocket client connections, is affected. Because the component does not properly validate server certificates, an attacker could potentially impersonate a trusted server, creating a risk of intercepted or manipulated communications.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Unitree Robotics Unitree Go2: 1.1.0, 1.1.1, 1.1.2, 1.1.3, 1.1.4, 1.1.5, 1.1.6, 1.1.7, 1.1.8, 1.1.9, 1.1.10, 1.1.11, 1.1.12, 1.1.13, 1.1.14.0, 1.1.14.1, 1.1.15.0, 1.1.15.1

## Description

A vulnerability was detected in Unitree Robotics Unitree Go2 up to 1.1.13/1.1.14.1/1.1.15.1. This affects the function WebSocketClient.connect of the file websocket.py of the component chat_go. Performing a manipulation results in improper certificate validation. The attack may be initiated remotely. The attack's complexity is rated as high. The exploitability is reported as difficult. The vendor confirmed early: "These issues were previously submitted by the researcher through our Security Response Center platform and are tracked internally as follows: Submission 990504 corresponds to our internal ticket #616 (Go2 chat_go WSS client disabled TLS server certificate validation, CWE-295)."
