EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.6 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 76% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
