CVE-2026-58408 ChurchCRM CVE debrief

Who should care

Users of ChurchCRM, especially those with low-privileged accounts, should be aware of this vulnerability and take steps to protect their systems. This vulnerability has been fixed in version 7.4.0. Affected operators, platforms, and security teams should prioritize updates and compensating controls.

Technical summary

The vulnerability exists in the ChurchCRM system, specifically in the POST /CSVCreateFile.php endpoint. This endpoint generates and streams a CSV containing the full Personally Identifiable Information (PII) of every Person/Family record in the database. The issue arises from the lack of a dedicated isAdmin() or bExportData authorization check, allowing any single non-admin permission flag to reach the CSV bulk-export endpoint. Defenders should focus on restricting access and implementing additional authorization checks.

Defensive priority

High

Recommended defensive actions

• Update ChurchCRM to version 7.4.0 or later
• Restrict access to the /admin/export UI
• Monitor for suspicious activity on the /CSVCreateFile.php endpoint
• Implement additional authorization checks for data export
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
