CVE-2026-22174: OpenClaw < 2026.2.22 - Gateway Token Disclosure via Chrome CDP Probe

• Severity: medium (CVSS 6.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.1% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-03-18 · updated 2026-06-17
• Weakness: CWE-306

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.

Affected products

• OpenClaw: before 2026.2.22 — fixed in 2026.2.22

How to fix

Upgrade to a fixed version: OpenClaw 2026.2.22. Check the vendor advisory for mitigations.
