Ninja Forms – The Contact Form Builder That Grows With You

The Ninja Forms - The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.14.1 via a callback function for the admin_enqueue_scripts action handler in blocks/bootstrap.php. This makes it possible for authenticated attackers, with Contributor-level access and above, to gain access to an authorization token to view form submissions for arbitrary forms, which could potentially contain sensitive information.

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 `ninja_forms_merge_tags` filter to user-supplied input within repeater fields, which allows the resolution of `{post_meta: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 `nf_ajax_submit` AJAX action.

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 – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the /ninja-forms-views/token/refresh function in all versions up to, and including, 3.13.2. This makes it possible for unauthenticated attackers to generate a token and view arbitrary form submissions. This is a duplicate of CVE-2025-11924.

The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.12.0. This is due to missing or incorrect nonce validation on the maybe_opt_in() function. This makes it possible for unauthenticated attackers to opt an affected site into usage statistics collection via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.12.0. This is due to missing or incorrect nonce validation when exporting CSV files. This makes it possible for unauthenticated attackers to delete those files granted they can trick an administrator into performing an action such as clicking on a link.

The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.11.0 via deserialization of untrusted input. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the use of a templating engine in all versions up to, and including, 3.10.2.1 due to insufficient output escaping on user data passed through the template. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 3.10.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
