Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in David de Boer Paytium: Mollie payment forms & donations allows Stored XSS.This issue affects Paytium: Mollie payment forms & donations: from n/a through 4.4.2.

The Paytium: Mollie payment forms & donations WordPress plugin before 4.3.7 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).
