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. In the plugin settings, select "WPBot Lite > Settings > Change Language" 
2. Select "FAQ" and in the "Welcome to FAQ Section" enter the payload `<script>alert(2)</script>`
3. Access the FAQ on the frontend to see XSS.
