Vulnerability Summary

CVE-2026-22174: 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.
