WordPress Plugin Vulnerabilities
Responsive Pricing Table < 5.1.8 - Admin+ Stored Cross-Site Scriping
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. Create a New Pricing Table and Add a pricing plan. 2. Add the following malicious XSS payload in the "Short description" parameter. XSS payload: `"><scri<script>pt>alert(1)</scri</script>pt>` 3. Save the Pricing table and click the Instant preview button to see the XSS.
