CVE-2025-15705: Contact Form by Supsystic: Form-name stored cross-site scripting

Contact Form by Supsystic fails to sanitize and escape form names. A user with access to the form editor can store script in a form name that executes when another user views the form. On multisite, this crosses a privilege boundary because site administrators lack unfiltered_html. The minimum role outside that scenario, save action and output context are not disclosed in the export. Published affected versions: < 1.8.0.
