What is CVE-2025-15705?
The Contact Form by Supsystic WordPress plugin, prior to version 1.8.0, is vulnerable to an arbitrary web script injection. This vulnerability arises due to inadequate sanitization and escaping of form names, which allows users with access to the form editor to inject malicious scripts. These scripts execute when another user interacts with the form. In multisite environments, this issue poses an increased risk as it can breach privilege boundaries when administrators lack the unfiltered_html capability.
