Vulnerability from github – Published: 2026-02-10 06:30 – Updated: 2026-02-10 06:30

Details

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 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.

Severity ?

6.4 (Medium)


                  
                    CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N

Title

Fluent Forms <= 6.1.14 - Authenticated (Subscriber+) Stored Cross-Site Scripting via AI Form Builder Module

Summary

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.

Severity ?

6.4 (Medium)


                        
                          CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
