At a glance

CVE-2026-6222 is a medium-severity Missing Authorization vulnerability in the Forminator Forms WordPress plugin, affecting versions <= 1.51.1. It carries a CVSS score of 5.3 (reachable over the network; high confidentiality impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 1.52; sites on affected versions should update now. Disclosed May 2026, reported by anhcd05.

Vulnerability Overview

The Forminator Forms plugin for WordPress is vulnerable to Missing Authorization in versions up to and including 1.51.1. This is due to the `processRequest()` method in `Forminator_Admin_Module_Edit_Page` (admin/abstracts/class-admin-module-edit-page.php) dispatching sensitive module-management actions — including export, delete, clone, delete-entries, publish/draft, and bulk variants — after only a nonce check, without ever verifying that the current user holds the `manage_forminator_modules` capability. The nonce used (`forminator_form_request`) is unconditionally embedded in the global `forminatorData` JavaScript object and localized on every Forminator admin page, including Templates and Reports pages accessible to users who explicitly lack module-management permissions. Because `processRequest()` is invoked during the `admin_menu` action hook — which fires before WordPress enforces page-level capability checks — a user whose Forminator role is restricted to Templates or Reports can craft a valid POST request targeting any published module and successfully trigger the vulnerable actions. This makes it possible for authenticated attackers with subscriber-level access (or any custom low-privilege Forminator role) to export the complete internal configuration of arbitrary forms/polls/quizzes (including notification routing, integration credentials, and conditional logic), delete modules, delete all submissions/votes, clone modules, or bulk-change publish/draft status.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-862: Missing Authorization

Forminator Forms <= 1.51.1 carries this weakness at processRequest(), and reaching it takes an account at Subscriber level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Forminator Forms the fix is 1.52: builds <= 1.51.1 are affected, anything from 1.52 onward is not.

Remediation

Update to version 1.52, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Forminator Forms 1.52 closes this, and updating the plugin is the step that ends it.
