Overview

civicrm/civicrm-core is an open source constituent relationship management for non-profits, NGOs and advocacy organizations.

Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF). CiviCRM did not provide sufficient protection on the CKEditor configuration form, which could allow a malicious third-party to trick a CiviCRM administrator into changing the configuration.
