WordPress Plugin Vulnerabilities
Smart Forms < 2.6.96 - 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. Add a new form or edit an existing form 2. In the CSS field, enter the payload `</script><script>alert(/XSS: CSS/)</script>`. In the "After Submit" section, enter the payload `<script>alert(/XSS: after submit alert /)</script>` for the "Show Alert Message". 3. View the form and then see the XSS
