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)

In the plugin's settings (WooCommerce > Settings > Currency > Frontend Switcher), tick "Enable switcher" and put the following payload in the "Panel header text" settings: <img src onerror=alert(/XSS/)>

Save the settings. The XSS will be triggered when viewing the settings page again, as well as in any frontend page
