AI-Generated

NextCRM version 0.12.1 is vulnerable due to improper authorization in its MCP campaign tools, allowing low-privileged authenticated users to access and manipulate campaigns created by others using valid Bearer API tokens. This flaw enables unauthorized enumeration, reading, updating, and deletion of campaigns, posing significant risks to data integrity and confidentiality. Organizations using this version of NextCRM should prioritize upgrading to version 0.12.2 to mitigate these security risks.

Original NVD Description

NextCRM is open-source customer relationship management (CRM) software. In version 0.12.1, the MCP campaign tools expose campaign read and write operations over the network using user-generated Bearer API tokens (`nxtc__...`). The application has an authorization model that restricts normal users to campaigns they created, but multiple MCP campaign handlers ignore the authenticated user ID and query or mutate campaigns only by object ID. As a result, a low-privileged authenticated user with a valid MCP API token can enumerate all campaigns, read campaign details, update or delete campaigns owned by other users, modify campaign templates and steps, and potentially trigger or pause campaign delivery. Version 0.12.2 fixes the issue.
