CVE-2026-55550
Published:July 20, 2026
Updated:August 04, 2026
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.
