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)

Set “Greeting Text” option to:
<script>alert(1)</script>

Set “Enable the login box shortcode? [wplb]” option to:
Enabled

Shortcode:
