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.

• CWE-79Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
