Front End Users <= 3.2.35 - Unauthenticated Membership Level and Account Status Self-Assignment

The Front End Users WordPress plugin through 3.2.35 does not restrict which account attributes a visitor may set when registering through its front-end forms, allowing unauthenticated users to assign themselves an arbitrary membership level and to mark their own account as approved, confirmed and paid, bypassing the Front End Users WordPress plugin through 3.2.35's content restrictions and its registration gating.
