Description

The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to unauthorized access of data due to a missing authorization check on the 'ninja-forms-views/token/refresh' REST callback in all versions up to, and including, 3.14.1. This makes it possible for unauthenticated attackers to view form submissions, which could potentially contain sensitive information.
