WP Login Box <= 2.0.2 - Admin+ Stored XSS

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)

PoC

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