Detailsinfo

A vulnerability was found in OpenClaw up to 2026.4.19. It has been rated as problematic. Affected by this issue is an unknown part of the component MiniMax API. The manipulation of the argument MINIMAX_API_HOST with an unknown input leads to a confused deputy vulnerability. Using CWE to declare the problem leads to CWE-441. The product receives a request, message, or directive from an upstream component, but the product does not sufficiently preserve the original source of the request before forwarding the request to an external actor that is outside of the product's control sphere. This causes the product to appear to be the source of the request, leading it to act as a proxy or other intermediary between the upstream component and the external actor. Impacted is confidentiality. CVE summarizes:
