CVE-2026-58411: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in ChurchCRM CRM
ChurchCRM is an open-source church management system. Prior to version 7.4.0, Cross-Site Scripting (XSS) vulnerabilities were identified due to insufficient output encoding of user-controlled request parameter names and parameter values. The application reflects attacker-controlled input into JavaScript string contexts and HTML attribute contexts without proper sanitization or contextual output encoding. Affected endpoints observed during testing: /FamilyCustomFieldsEditor.php, /PaddleNumList.php and /admin/system/church-info. Potential consequences include session-token theft, account takeover, unauthorized actions on behalf of authenticated users, exposure of sensitive church member information, credential harvesting, phishing, and privilege escalation when administrators are targeted. This issue has been resolved in version 7.4.0.

Affected endpoints include /FamilyCustomFieldsEditor.php, /PaddleNumList.php, and /admin/system/church-info. The vulnerability has been fixed in version 7.4.0.
Potential Impact
Successful exploitation can result in session-token theft, account takeover, unauthorized actions performed on behalf of authenticated users, exposure of sensitive church member information, credential harvesting, phishing attacks, and privilege escalation especially when administrators are targeted.
