EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.7%, top 51% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
