- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L

## Affected

- pdovhomilja nextcrm-app: 0.12.1

## 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.
