Description

The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 3.13.2. This is due to the plugin not properly verifying that a user is authorized before the `ninja-forms-views` REST endpoints return form metadata and submission content. This makes it possible for unauthenticated attackers to read arbitrary form definitions and submission records via a leaked bearer token granted they can load any page containing the Submissions Table block. NOTE: The developer released a patch for this issue in 3.13.1, but inadvertently introduced a REST API endpoint in which a valid bearer token could be minted for arbitrary form IDs, making this patch ineffective.

• CWE-639Authorization Bypass Through User-Controlled KeyThe system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
