Pray For Me <= 1.0.4 is vulnerable to Cross Site Request Forgery (CSRF) Leading to Plugin Settings Change vulnerability

The Pray For Me plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.4. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to update the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
