Ultimate Maps by Supsystic < 1.2.16 – Admin+ Stored XSS | CVE 2023-6732 | Plugin Vulnerabilities

Description

The plugin does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Cross-Site Scripting attacks even when unfiltered_html is disallowed

Proof of Concept

Go to the Marker Categories settings of the plugin (/wp-admin/admin.php?page=ultimate-maps-supsystic&tab=marker_groups), add/edit a category and put the following payload as a title: text"autofocus/onfocus=alert(1)//

The XSS will be triggered when editing the related category again
