Forminator Forms <= 1.51.1 - Missing Authorization to Authenticated (Subscriber+) Sensitive Information Disclosure via 'forminator_action' Parameter

  • Disclosed: 06.05.2026
  • Updated: 11.10.2026 10:23

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.
