Detailsinfo

A vulnerability was found in OpenClaw up to 2026.3.21. It has been declared as problematic. This vulnerability affects an unknown part of the file host-env-security-policy.json of the component Environment Variable Handler. The manipulation with an unknown input leads to a permissive list of allowed inputs vulnerability. The CWE definition for the vulnerability is CWE-183.
