Description
OpenClaw before 2026.3.22 contains an authentication bypass vulnerability in the X-Forwarded-For header processing when trustedProxies is configured, allowing attackers to spoof loopback hops. Remote attackers can inject forged forwarding headers to bypass canvas authentication and rate-limiting protections by masquerading as loopback clients.
