ChurchCRM is an open-source church management system. Versions prior to 7.1.0 have an SQL injection vulnerability in the endpoints `/GroupPropsFormRowOps.php`, `/PersonCustomFieldsRowOps.php`, and `/FamilyCustomFieldsRowOps.php`. A user has to be authenticated.
For `ManageGroups` privileges have to be enabled and for the other two endpoints the attack has to be executed by an administrative user. These users can inject arbitrary SQL statements through the `Field` parameter and thus modify tables from the database. This vulnerability is fixed in 7.1.0.
