FormCraft < 1.2.7 - 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).

PoC

There are two XSS issues: Example A: 1. Create a new form. 2. Go to settings and then to custom messages. 3. In form sent replace message sent with payload. Example B: 1. Go to add field and then add email. 2. In label change your email to payload 3. Now return to your submissions and click on the recent submission you made to see the XSS.
