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 » Login rebuilder
 
2. In Login file keyword, add payload: "><iframe src="<svg onload=alert(4);>">
 
3. Save the changes to trigger XSS.
