CVE-2026-55550 | NextCRM is open-source customer relationship management (CRM… | CVSS 7.1 HIGH

Description

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.
