CVE-2026-58408: CWE-862: Missing Authorization in ChurchCRM CRM
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.
AI Analysis
Technical Summary
CVE-2026-58408 is a missing authorization vulnerability (CWE-862) in ChurchCRM's CSV export functionality. Before version 7.4.0, the POST /CSVCreateFile.php endpoint streams a CSV containing all member PII without enforcing proper feature-level or object-level authorization. The endpoint incorrectly allows any user with a single non-admin permission to access sensitive data, bypassing intended admin-only restrictions. The flaw is due to the absence of a dedicated isAdmin() or equivalent export-specific authorization check. This vulnerability was addressed in ChurchCRM version 7.4.0.
Potential Impact
An attacker with low privileges can exfiltrate the entire member directory, including sensitive personally identifiable information, without proper authorization. This leads to a confidentiality breach of all Person/Family records stored in the CRM. There is no impact on integrity or availability reported.
Mitigation Recommendations
This vulnerability is fixed in ChurchCRM version 7.4.0. Users should upgrade to version 7.4.0 or later to remediate this issue. No other official remediation or temporary fix is documented. Patch status is not explicitly stated but the fix is confirmed in version 7.4.0.
