Executive brief
Ninja Forms, a popular WordPress plugin used for creating contact forms, contains a security flaw that allows unauthorized access to submitted data. An attacker can exploit this to view information submitted by users through these forms without needing to log in. This could lead to the exposure of sensitive customer information, such as personal details or private inquiries, potentially resulting in privacy violations and reputational damage.
Technical details
The vulnerability is classified as a Missing Authorization (CWE-862) flaw within the 'ninja-forms-views/token/refresh' REST callback. Because the plugin fails to perform an identity or permission check on this specific endpoint, any unauthenticated user can trigger the callback. Successful exploitation allows a remote attacker to retrieve and view form submission data stored by the plugin. The issue affects all versions up to and including 3.14.1; a fix was introduced in changeset 3489168.
