CVE-2026-76639 is an unauthenticated, network-adjacent root remote-code-execution vulnerability in Unitree G1 EDU firmware through 1.5.2. The ChatGo knowledge-upload API insufficiently validates a caller-controlled upload identifier, enabling path traversal and arbitrary file writes as root. An attacker can use the unauthenticated DDS communication path to restart BashRunner, causing its startup-time file whitelist to include the planted payload. BashRunner subsequently invokes whitelisted content through a shell subprocess without enforcing a safe file type, resulting in execution as uid 0 on the Locomotion PC. The attack chain also relies on exposed WebRTC-to-DDS access and a static device key readable by unprivileged local users.

A path-traversal vulnerability in the Unitree G1 EDU chat_go component that enables access to bashrunner and arbitrary root-code execution on the robot's Locomotion PC.
An unauthenticated root remote-code-execution chain in the Unitree G1 AI chatbot (chat_go) service. Path traversal in knowledge-file uploads enables arbitrary file writes, followed by trusted execution by the bashrunner service.
A root remote-code-execution chain in Unitree G1's ChatGo AI and BashRunner services. A path traversal in the knowledge-upload feature permits writing an attacker-controlled file to a BashRunner-trusted directory; restarting the service causes execution as root.
A network-adjacent root remote-code-execution chain affecting the Unitree G1 EDU robot. The chain uses the chat_go and bashrunner components to obtain root execution on the robot's Locomotion PC.
