CVE-2026-3492
CWE-79Published: March 11, 2026· Updated: Mar 11, 2026
Official Description
The Gravity Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 2.9.28.1. This is due to a compound failure involving missing authorization on the `create_from_template` AJAX endpoint (allowing any authenticated user to create forms), insufficient input sanitization (`sanitize_text_field()` preserves single quotes), and missing output escaping when the form title is rendered in the Form Switcher dropdown (`title` attribute constructed without `esc_attr()`, and JavaScript `saferHtml` utility only escapes `&`, `<`, `>` but not quotes). This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary JavaScript that executes when an Administrator searches in the Form Switcher dropdown in the Form Editor.
Technical Analysis
CVE-2026-3492 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
