NVD description
OpenClaw versions prior to 2026.2.22 inject the x-OpenClaw-relay-token header into Chrome CDP probe traffic on loopback interfaces, allowing local processes to capture the Gateway authentication token. An attacker controlling a loopback port can intercept CDP reachability probes to the /json/version endpoint and reuse the leaked token as Gateway bearer authentication.
What to do
- Upgrade OpenClaw to
2026.2.22or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
