Summary

CordysCRM is an open source AI-powered customer relationship management system that supports private deployment. Prior to 1.7.2, GET /mcp/form/config/{formKey} calls McpController.getMcpField without authentication because ShiroFilter.addPublicPathFilters marks /mcp/** as anonymous and the controller has no permission annotation. An unauthenticated caller can obtain field names, types, required flags, default values, options, validation rules, and binding sources for CRM modules, allowing reconstruction of the application data model and more targeted attacks against other inputs. This issue is fixed in version 1.7.2.
