What is CVE-2026-41913?

The vulnerability in OpenClaw involves a race condition in the shared-secret authentication mechanism. This flaw allows attackers to exploit the system by initiating multiple concurrent authentication requests, effectively bypassing the intended rate-limiting protections.

Immediate updates to the affected versions are recommended to ensure robust protection against such exploits.
