Input validation vulnerability in a3 Responsive Slider 2.1.0

The a3 Responsive Slider plugin for WordPress is vulnerable to a security issue called Cross-Site Request Forgery. This affects versions up to and including 2.1.0. This means that attackers who are not authenticated can inject malicious JavaScript into pages on the website. This code will run each time a user visits the page, if they can trick an administrator into clicking on a link or performing another action. To protect against this, website administrators should make sure that they have the latest version of the plugin installed.
