WordPress Plugin Vulnerabilities
Popup box < 3.8.6 - Admin+ Stored XSS in Popup Settings
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. Add a new Popup 2. In the "Popups > Settings" section, add the PoC `"><script>alert(92)</script>` for any of the "Close Button" parameters. 3. Save and navigate back to the popups and see the XSS.
