Get URL Cron <= 1.4.7 - Cross-Site Request Forgery via geturlcron_action_handle

The Get URL Cron plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.4.7. This is due to missing or incorrect nonce validation on the geturlcron_action_handle function called via an init hook. This makes it possible for unauthenticated attackers to modify many of the plugin's settings and create cron jobs, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
