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.
