CVE-2026-2268
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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.

dbcve analysis · high confidenceThe Ninja Forms WordPress plugin versions up to 3.14.0 has an insecure implementation of the `ninja_forms_merge_tags` filter in repeater fields that resolves `{post_meta:KEY}` merge tags without authorization. Unauthenticated attackers can exploit this via the `nf_ajax_submit` AJAX action to extract arbitrary post metadata including sensitive data like WooCommerce billing emails, API keys, and customer personal information.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Ninja Forms plugin installation and versionIn WordPress admin, go to Plugins > Installed Plugins and find Ninja Forms. Check the version number displayed, or inspect the plugin header in wp-content/plugins/ninja-forms/includes/index.phpAffected if The installed version is 3.14.0 or lower (any version up to and including 3.14.0)
-
Confirm the vulnerable AJAX endpoint is activeCheck if the nf_ajax_submit AJAX action is registered and publicly accessible. This can be verified by examining the plugin's AJAX handlers in includes/AJAX/Controllers/Submit.php or by checking if the action 'wp_ajax_nf_ajax_submit' or 'wp_ajax_nopriv_nf_ajax_submit' is hookedAffected if The AJAX endpoint accepts unauthenticated requests (wp_ajax_nopriv_ hook exists)
-
Identify use of repeater fields with merge tagsReview active Ninja Forms for any form that uses repeater fields. Check if any field settings or notification emails contain {post_meta:KEY} merge tags, which trigger the vulnerable filterAffected if Any form uses repeater fields with {post_meta:...} merge tags in field labels, default values, or notifications
You are affected if Ninja Forms version is 3.14.0 or lower AND the nf_ajax_submit endpoint is exposed to unauthenticated users AND your forms use repeater fields with post_meta merge tags.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpdate Ninja Forms to version 3.14.1 or later immediately. Until patched, consider disabling the plugin or restricting access to the nf_ajax_submit AJAX endpoint.
Ninja Forms version 3.14.1 or later (latest stable release)
- Navigate to the WordPress admin dashboard
- Go to Plugins > Installed Plugins
- Locate Ninja Forms plugin
