Affected: openclaw/openclaw
Attack vector: auth-bypass
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2026-22174
CWE: CWE-306
CVSS: 6.8 (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N)

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.
