What is CVE-2026-32045?

OpenClaw versions before 2026.2.21 have a significant security vulnerability that arises from the inappropriate application of tokenless Tailscale header authentication on HTTP gateway routes. This misconfiguration allows unauthorized parties, particularly those on trusted networks, to bypass necessary authentication measures, gaining unwarranted access to sensitive HTTP gateway routes without needing valid tokens or passwords. This poses a serious risk to the integrity of networked services relying on OpenClaw for secure access management.
