CVE-2026-26317: OpenClaw affected by cross-site request forgery (CSRF) through loopback browser mutation endpoints

February 18, 2026 (updated February 20, 2026)

Browser-facing localhost mutation routes accepted cross-origin browser requests without explicit Origin/Referer validation. Loopback binding reduces remote exposure but does not prevent browser-initiated requests from malicious origins.
