WordPress Plugin Vulnerabilities
WP Post Popup <= 3.7.3 - Admin+ Stored XSS
Description
The plugin does not sanitise and escape some of its inputs, 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
Enter the following payload in the Close Button field in the plugin settings. `<img src=s onerror=alert("XSS")>` Save the settings and visit the homepage to see the XSS.
