Summary
Vulnerability in the Ninja Forms WordPress plugin version 3.14.8 and earlier. Missing authorization in the Gutenberg block 'ninja-forms/submissions-table' allows authenticated attackers with Author role to expose stored form submissions (including PII) to unauthenticated visitors.
Risk Assessment
The risk is the leakage of sensitive personal data (names, emails, phone numbers) collected in forms, potentially violating user privacy and GDPR regulations.
Recommendation
Update the Ninja Forms plugin to the latest version. Restrict Author permissions to publish blocks with forms. Remove unnecessary bearer tokens from page source.

The Ninja Forms plugin version 3.14.8 and prior for WordPress Multisite contains an incorrect authorization vulnerability that allows a subsite Administrator to trigger network-wide deletion of all Ninja Forms data. Attackers can send a crafted POST request to the admin-ajax.php endpoint with the nf_delete_all_data action and a per-site nonce to invoke migration routines that unconditionally iterate all blogs via switch_to_blog(), dropping all nf3_* tables and clearing options and transients across every subsite in the network without requiring super-admin or network-admin privileges.
- CVE-2026-65048Critical
The Ninja Forms plugin for WordPress versions 3.10.4 through 3.14.9 contains an unauthenticated stored cross-site scripting vulnerability in the Repeatable Fieldset feature. The parseSubmissionIndex() function accepts arbitrary strings as submission indexes without numeric validation, and admin_form_element() interpolates the index directly into HTML without escaping. An unauthenticated attacker can submit a public form with a crafted repeater child key containing malicious script payloads, which execute in an administrator's browser when viewing submissions in the WordPress admin panel.
- CVE-2019-10869High
The Ninja Forms plugin for WordPress before version 3.0.23 (when the Uploads add-on is activated) contains path traversal and unrestricted file upload vulnerabilities. This allows an attacker to traverse the file system to access files and execute code via the name and tmp_name parameters in includes/fields/upload.php.
- CVE-2026-15256Medium
The Ninja Forms WordPress plugin before 3.14.10 does not prevent user-supplied query-string input, used to pre-populate a form field's default value, from being processed as a shortcode, allowing unauthenticated attackers to execute arbitrary shortcodes registered on the site when a form so configured is embedded on a public page.
- CVE-2026-15663Medium
The Ninja Forms plugin for WordPress is vulnerable to generic SQL injection via import files. An authenticated attacker with admin privileges can append SQL queries to existing ones to extract sensitive data from the database.
- CVE-2026-65052High
Ninja Forms WordPress plugin version 3.14.8 and earlier contains an improper input validation vulnerability. Unauthenticated attackers can inject arbitrary numeric values into form calculations and payment totals by submitting values that do not match any configured option in ListSelect or ListRadio fields. This can lead to manipulation of payment amounts, including setting them to zero.
- CVE-2026-65051Medium
Vulnerability in the Ninja Forms WordPress plugin version 3.14.8 allows unauthenticated attackers to bypass form validation by merging attacker-controlled field metadata before validation. Attackers can send a malicious AJAX request, overriding field types, removing required flags, and disabling CAPTCHA.
- CVE-2026-1239High
The Ninja Forms plugin for WordPress is vulnerable to unauthorized data access due to a missing authorization check on the 'ninja-forms-views/token/refresh' REST callback in all versions up to and including 3.14.1. This allows unauthenticated attackers to view form submissions, which may contain sensitive information.
Original NVD description (English source)
Ninja Forms WordPress plugin version 3.14.8 and prior contains a missing authorization vulnerability in the render callback of the `ninja-forms/submissions-table` Gutenberg block that allows authenticated attackers with Author-level privileges to expose stored form submissions to unauthenticated visitors by embedding the block with an arbitrary formID on a published post. Attackers can retrieve the signed bearer token injected into every page visitor's browser via `wp_localize_script` and use it against the REST API submissions endpoint to access all saved form submission field values, including sensitive personally identifiable information such as names, email addresses, and phone numbers.
