WP Frontend Profile <= 1.3.8 - Cross-Site Request Forgery to Unauthorized User Account Approval or Rejection

The WP Frontend Profile plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.3.8. This is due to missing nonce validation on the 'update_action' function. This makes it possible for unauthenticated attackers to approve or reject user account registrations via a forged request granted they can trick an administrator into performing an action such as clicking on a link.
