CVE-2026-58408 Details
Description
ChurchCRM is an open-source church management system. Prior to version 7.4.0, a low-privileged user can bypass the /admin/export UI and exfiltrate the entire member directory. The POST /CSVCreateFile.php endpoint generates and streams a CSV containing the full Personally Identifiable Information (PII) of every Person/Family record in the database, without performing any feature-level or object-level authorization check beyond the coarse "has any admin permission" gate inherited from the legacy page bootstrap. In other words, any single non-admin permission flag is enough to reach the CSV bulk-export endpoint, even though such users should not have data export rights. The export script is missing a dedicated isAdmin() (or a new bExportData) authorization check of its own. This issue has been fixed in version 7.4.0.
A broken access control vulnerability has been identified in ChurchCRM versions prior to 7.4.0. The issue allows low-privileged users to bypass the admin export interface and exfiltrate the entire member directory. This is achieved by directly submitting export form data to the CSVCreateFile.php endpoint, which generates a CSV file containing full Personally Identifiable Information (PII) for every person and family record in the database. The vulnerability arises because the export endpoint lacks proper authorization checks, only relying on a generic 'has any admin permission' gate, which is too permissive for bulk PII exports.
Users should update to ChurchCRM version 7.4.0 or later, where this vulnerability has been fixed.
