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 widget area, add the widget "HL Twitter"
2. For the "Title" enter the payload `"><script>alert(1)</script>`
3. Save the widget and view the frontend to see the XSS
