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.","published":"2026-08-27T20:18:38.230","modified":"2026-08-27T20:18:38.230","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://boschko.ca/g1-ble-rce/"},{"type":"WEB","url":"https://github.com/OlivierLaflamme/UniBLEed"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/unitree-g1-edu-unauthenticated-rce-via-dds-bridge-and-path-traversal"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T20:18:38.230"}}
