CVE-2025-15705

Contact Form by Supsystic < 1.8.0 - Admin+ Stored XSS

Published Oct 25, 2026 CVSS 3.1 · 3.5 Low EPSS < 1% KEV · Not listed
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.
