CVE-2026-63646Public exploitNetwork attack vector

Unauthenticated schema disclosure via anonymous MCP route

Published Sep 18, 2026 · Updated Sep 18, 2026

Information disclosure in Cordys CRM before 1.7.2 allows remote attackers to read CRM field schemas through an unauthenticated HTTP endpoint. ShiroFilter.addPublicPathFilters marks /mcp/** anonymous, while McpController.getMcpField lacks a permission check and returns field metadata. Network access is sufficient to reconstruct module data models, but the flaw does not disclose CRM record contents or directly modify data.
