The plugin does not sanitise and escape one of its settings, allowing high privilege users such as admin to use Cross-Site Scripting payload even when the unfiltered_html capability is disallowed.

Put the following payload in the Simple Banner Text setting of the plugin: <img src onerror=alert(/XSS/)>

The XSS will be triggered in the plugin's settings, as well as any frontend page with the banner
