Official description

The Custom Login And Signup Widget plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0. This is due to missing or incorrect nonce validation in the /frndzk_adminclsw.php file. This makes it possible for unauthenticated attackers to change the email and username settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
