Detailsinfo

A vulnerability classified as problematic was found in Ninja Forms Plugin up to 3.13.1/3.13.2 on WordPress. This vulnerability affects an unknown part of the component REST Endpoint. The manipulation with an unknown input leads to a resource injection vulnerability. The CWE definition for the vulnerability is CWE-99. The product receives input from an upstream component, but it does not restrict or incorrectly restricts the input before it is used as an identifier for a resource that may be outside the intended sphere of control. As an impact it is known to affect confidentiality. CVE summarizes:

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.

The advisory is available at wordfence.com. This vulnerability was named CVE-2025-11924. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. The technical details are unknown and an exploit is not available.
