Detailsinfo

A vulnerability, which was classified as problematic, was found in ChurchCRM up to 7.3.x. Affected is the function isAdmin of the file CSVCreateFile.php of the component CSV bulk-export endpoint. The manipulation with an unknown input leads to a improper authorization vulnerability. CWE is classifying the issue as CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. This is going to have an impact on confidentiality. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-58408 since 06/30/2026. The exploitability is told to be easy.
