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 Ninja Forms plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.14.0. This is due to the unsafe application of the ninjaformsmergetags filter to user-supplied input within repeater fields, which allows the resolution of {postmeta:KEY} merge tags without authorization checks. This makes it possible for unauthenticated attackers to extract arbitrary post metadata from any post on the site, including sensitive data such as WooCommerce billing emails, API keys, private tokens, and customer personal information via the nfajaxsubmit AJAX action.
