CVE-2025-15705 Details
Description
The Contact Form by Supsystic WordPress plugin before 1.8.0 does not sanitise and escape a form name, allowing users with access to the form editor to inject arbitrary web scripts that execute when another user views the form. On multisite installations, where administrators do not hold the unfiltered_html capability, this crosses a privilege boundary.
A stored cross-site scripting vulnerability has been identified in the Contact Form by Supsystic WordPress plugin, affecting versions prior to 1.8.0. The issue arises because the plugin fails to properly sanitize and escape form names, allowing users with access to the form editor to inject arbitrary scripts. These scripts are executed when another user views the form. This vulnerability is particularly concerning on multisite installations, where administrators lack the unfiltered_html capability, as it bypasses privilege restrictions.
Users are advised to update the Contact Form by Supsystic WordPress plugin to version 1.8.0 or later.
