Does this matter?

Lower severity and a low EPSS score (0.36%). Track it; it rarely justifies an emergency change on its own.

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.
