CVE-2026-55550: CWE-269: Improper Privilege Management in pdovhomilja nextcrm-app
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.

Technical Summary
CVE-2026-55550 describes an improper privilege management vulnerability (CWE-269) in the nextcrm-app by pdovhomilja. In version 0.12.1, the MCP product tools expose product catalog write operations through the /api/mcp/mcp endpoint using user-generated Bearer tokens but fail to enforce role-based access control. This allows authenticated users with low privileges to perform unauthorized product creation, modification, archiving, or soft deletion. The vulnerability is resolved in version 0.12.3.
Potential Impact
The vulnerability enables unauthorized modification of the CRM product catalog by any authenticated user who can generate an MCP API token. This can lead to integrity issues in the product data, potentially disrupting business operations relying on accurate product information. Confidentiality is not impacted, but integrity is highly affected. Availability impact is low.
Mitigation Recommendations
Upgrade to nextcrm-app version 0.12.3 or later, where this improper privilege management vulnerability has been fixed. Until upgrading, restrict access to the MCP API tokens and monitor for unauthorized use. Patch status is not explicitly confirmed in the advisory, but the fix is stated to be in version 0.12.3.
