The plugin does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).

1. Put the following payload in any of the plugin's settings with a text field and save: " style=animation-name:rotation onanimationstart=alert(/XSS/)//

2. The XSS will be triggered when accessing the settings page again.
