Sticky Action Buttons <= 1.1 - Cross-Site Request Forgery to Plugin Settings Update

The Sticky Action Buttons plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1. This is due to missing or incorrect nonce validation on the sabs_options_page_form_submit() function. This makes it possible for unauthenticated attackers to update plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
