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. Navigate to "URL Shortify > Settings > Links"
2. Add `"><script>alert(1)</script>` to the "Link Prefix" and save.
3. Go to "Links > Add New" to see the XSS.
