Until a fix is available, restrict the assignment of the view_contacts capability to trusted users only and monitor access to the REST API endpoint. Avoid granting roles like Sales Rep the view_contacts capability without additional controls.
Description
Groundhogg CRM plugin for WordPress up to version 4.5.2 has an authorization bypass vulnerability via its REST API endpoint. Authenticated users with the view_contacts capability but without view_others_contacts can access any contact record, including sensitive personal information and user capabilities. This occurs because the endpoint lacks proper object-level ownership checks.
