      "value": "NextCRM is open-source customer relationship management (CRM) software. The CRM product catalog is an organization-wide business object. Normal application server actions restrict product creation, update, and deletion to `manager` and `admin` roles. However, in version 0.12.1, the MCP product tools expose the same write operations through `/api/mcp/mcp` using user-generated Bearer tokens and do not enforce role checks. Any authenticated low-privileged user who can generate an MCP API token can create, modify, archive, or soft-delete products in the shared CRM product catalog. Version 0.12.3 contains a fix."

Las acciones normales del servidor de aplicaciones restringen la creación, actualización y eliminación de productos a los roles de ’manager’ y ’admin’. Sin embargo, en la versión 0.12.1, las herramientas de productos de MCP exponen las mismas operaciones de escritura a través de ’/api/mcp/mcp’ utilizando tokens Bearer generados por el usuario y no aplican comprobaciones de rol. Cualquier usuario autenticado con bajos privilegios que pueda generar un token de API de MCP puede crear, modificar, archivar o eliminar de forma lógica productos en el catálogo de productos de CRM compartido. La versión 0.12.3 contiene una corrección."
