Detailsinfo

A vulnerability was found in OpenClaw up to 2026.2.21. It has been classified as critical. Affected is an unknown functionality of the file /json/version of the component Authentication Token Handler. The manipulation with an unknown input leads to a missing authentication vulnerability. CWE is classifying the issue as CWE-306. The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
