{"apiVersion":"1.0","identifier":"CVE-2026-76639","description":"Unitree G1 EDU firmware through 1.5.2 contains an unauthenticated remote code execution vulnerability that allows network-adjacent attackers to execute arbitrary commands as root by chaining three weaknesses: an unauthenticated WebRTC-to-DDS bridge on TCP port 9991, a static AES-128 key stored with world-readable permissions, and a path traversal flaw in the chat_go knowledge upload API. Attackers can publish DDS control messages to restart the bashrunner service, plant a malicious payload in its script execution directory via path traversal, and trigger execution of that payload as uid 0 through the bashrunner shell subprocess.","publishedAt":"2026-08-27T20:18:38","lastModifiedAt":"2026-08-27T20:18:38","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-76639","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00714,"riskScore":0.94,"affectedProduct":"Unitree G1 EDU","affectedVersions":"<=1.5.2","vulnerabilityType":"Firmware","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-76639","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-76639","en":"https://www.redsauce.net/en/cves/CVE-2026-76639","fr":"https://www.redsauce.net/fr/cves/CVE-2026-76639","pt":"https://www.redsauce.net/pt/cves/CVE-2026-76639","de":"https://www.redsauce.net/de/cves/CVE-2026-76639","sk":"https://www.redsauce.net/sk/cves/CVE-2026-76639","el":"https://www.redsauce.net/el/cves/CVE-2026-76639"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-76639"}}
