Summary
The Contact Form by Supsystic WordPress plugin, a contact form builder for WordPress sites, is affected. An authenticated user with form editing access can inject malicious scripts into a form name that run in the browser of anyone who views that form, and on multisite installations this can let a lower-privileged user bypass restrictions normally placed on administrators.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original 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.
