Description
ChurchCRM is an open-source church management system. Prior to 7.1.0, an authenticated API user can modify any family record's state without proper authorization by simply changing the {familyId} parameter in requests, regardless of whether they possess the required EditRecords privilege. /family/{familyId}/verify, /family/{familyId}/verify/url, /family/{familyId}/verify/now, /family/{familyId}/activate/{status}, and /family/{familyId}/geocode lack role-based access control, allowing users to deactivate/reactivate arbitrary families, spam verification emails, and mark families as verified and trigger geocoding. This vulnerability is fixed in 7.1.0.
Affected products
- ChurchCRM CRM: before 7.1.0 — fixed in 7.1.0
