New User Approve < 3.2.3 - Missing Authorization to Unauthenticated Arbitrary User Approval, Denial, and Information Disclosure

Description

The New User Approve plugin for WordPress is vulnerable to unauthorized access of data and modification of data due to a missing capability check on multiple REST API endpoints in all versions up to, and including, 3.2.2. This makes it possible for unauthenticated attackers to approve or deny user accounts, retrieve sensitive user information including emails and roles, and force logout of privileged users.
