CVE-2026-94047 Details
Description
A security vulnerability has been detected in samanhappy MCPHub up to 1.0.32. The impacted element is the function importTemplate of the file src/services/templateService.ts of the component Template Import Endpoint. The manipulation leads to improper privilege management. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may be used. Upgrading to version 1.0.33 is sufficient to resolve this issue. The identifier of the patch is 18a4467bc4ec6390b1f841d8a468a37e9922f837. It is advisable to upgrade the affected component.
A vulnerability in samanhappy MCPHub versions through 1.0.32 allows for improper privilege management in the template import feature. The issue arises in the 'importTemplate' function within 'src/services/templateService.ts', where the endpoint 'POST /api/templates/import' lacks adequate authorization checks. This vulnerability enables remote code execution by allowing non-admin users to import templates that create 'stdio'-type servers, which can execute arbitrary commands on the host system.
Upgrade to MCPHub version 1.0.33, which enforces the necessary privilege checks on the template import feature.
