CVE-2026-11881: Fluent Forms < 6.2.6 - Contributor+ Stored XSS via Date/Time Field

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.

Affected products

How to fix

Upgrade to a fixed version: Fluent Forms 6.2.6. Check the vendor advisory for mitigations.
