WordPress Plugin Vulnerabilities
User Meta < 2.4.3 - Admin+ Stored Cross-Site Scripting
Description
The plugin does not sanitise and escape the Form Name, as well as Shared Field Labels before outputting them in the admin dashboard when editing a form, which could allow high privilege users to perform Cross-Site Scripting attacks even when unfiltered_html is disallowed
Proof of Concept
An an admin - Create/edit a form and put the following payload in the Form name field: "><script>alert(/XSS-form-name/)</script> - Edit a Shared Field and put the following payload in the Field Label: "><script>alert(/XSS-field-label/)</script> Then edit the form again to trigger the XSS via Form Name, click on the shared field to trigger XSS via Field Label
