Description The plugin does not sanitise and escape some of its inputs, 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)

Enter the following payload in the Close Button field in the plugin settings.

`<img src=s onerror=alert("XSS")>`

Save the settings and visit the homepage to see the XSS.
