Lifecycle Timeline
2Description
The Fluent Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the AI Form Builder module in all versions up to, and including, 6.1.14 due to a combination of missing authorization checks, a leaked nonce, and insufficient input sanitization. The vulnerability allows Subscriber-level users to trigger AI form generation via a protected endpoint. When prompted, AI services will typically return bare JavaScript code (without <script> tags), which bypasses the plugin's sanitization. This stored JavaScript executes whenever anyone views the generated form, making it possible for authenticated attackers with Subscriber-level access and above to inject arbitrary web scripts that will execute in the context of any user accessing the form.

Stored cross-site scripting in the Fluent Forms WordPress plugin's AI Form Builder module (versions up to 6.1.14) enables authenticated subscribers to inject malicious scripts that execute for all users viewing affected forms through missing authorization checks, leaked nonces, and insufficient input sanitization of AI-generated content. An attacker with subscriber-level access can exploit this to perform actions on behalf of administrators or steal sensitive information from form viewers. …
