Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.3.22

Description When the trustedProxies setting is configured, the software incorrectly processes the X-Forwarded-For header, potentially allowing attackers to spoof loopback hops. This can bypass authentication and rate-limiting protections by presenting forged headers, effectively masquerading as a loopback client.

Recommendations Update to version 2026.3.22 or later.
