What it is

ChurchCRM is an open-source church management system. Prior to 7.1.0, a stored cross-site scripting issue affects the Directory Reports form fields set from config, Person editor defaults rendered into address fields, and external self-registration form defaults. This is primarily an admin-to-admin stored XSS path where writable configuration fields are abused. This vulnerability is fixed in 7.1.0.
