CVE-2025-66313Public exploitNetwork attack vector

Authenticated SQL injection via unfiltered FieldSec values

Published Dec 1, 2025 · Updated Dec 2, 2025

SQL injection in ChurchCRM 7.0.5 and earlier allows remote authenticated users to read database data via a crafted FieldSec value. PersonCustomFieldsEditor.php and FamilyCustomFieldsEditor.php place FieldSec POST values directly into SQL UPDATE and INSERT statements without integer validation. High-privilege access to the custom-field editors is required; blind queries can extract database contents or delay database processing.
