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)

1. Go to "Settings > NPS Monitoring" 
2. Add the payload `"><script>alert(3)</script>` in the "Title" field
3. Add the `[nps-computy]` shortcode to a page and view to see the XSS.
