Last modified

CVE-2026-22174 is a medium-severity vulnerability rated 5.9/10 on the CVSS scale. 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.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
