What is CVE-2026-101921?

The WPForms – AI Form Builder plugin for WordPress has a reflected cross-site scripting vulnerability via an attacker-controlled key parameter. This occurs due to inadequate input sanitization and output escaping in all versions up to and including 2.0.2.1. Attackers can exploit this vulnerability to inject malicious web scripts that execute when users interact with affected forms. Successful exploitation hinges on a site administrator having saved a form that includes a Smart Tag in an iframe srcdoc attribute and displaying the form description publicly.
