Vulnerability Title
Fluent Forms < 6.2.6 - Contributor+ Stored XSS via Date/Time Field
Source: CVE Program / CVE List V5
Vulnerability Description
The Fluent Forms WordPress plugin before 6.2.6 does not sanitise and escape one of its form field configuration settings before outputting it inside an inline script when a form is rendered, which could allow users with a role as low as Contributor (with delegated form-management permission, and therefore lacking the unfiltered_html capability, e.g. in a multisite setup) to perform Stored Cross-Site Scripting attacks that execute in the browser of any visitor who loads the form, including administrators previewing it.
