Description 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).

2. Select "Button action" as Link and insert the following payload: javascript:alert(document.cookie);
