WordPress Plugin Vulnerabilities

Popup box < 3.8.6 - Admin+ Stored XSS in Categories

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)

Proof of Concept

1. Go to "Popup Box > Categories"
2. Add a new category and in the description field add `<script>alert(1)</script>`
3. Save and see the XSS

Affects Plugins

Fixed in 3.8.6
