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).

In the plugin settings, add the POC <script>alert(1)</script> to the "External URL" or "Comments" fields and reload to see XSS.

Note: This must be tested on WordPress v5.8.7
