Overview

@payloadcms/plugin-form-builder is a Form builder plugin for Payload CMS

Affected versions of this package are vulnerable to Arbitrary Code Injection via insufficient access control on the FormSubmissions and Forms collections, where the read access check only verifies that a user is authenticated rather than confirming the user belongs to the admin collection. An authenticated non-admin user can read all form submissions and the sensitive emails field on forms, which may expose personally identifiable information and email configuration data.
