WordPress Plugin Vulnerabilities
Top Bar < 3.0.5 - Admin+ Stored XSS
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 "Top Bar" in WP Admin 2. Save the settings and intercept the request in Burp 3. Change the `tpbr_color` parameter to: `"+onmouseover='alert(1)'"` 4. Submit and see XSS when you mouseover the bar on the frontend
