At a glance

CVE-2026-1307 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Ninja Forms WordPress plugin, affecting versions <= 3.14.1. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 3.14.2; sites on affected versions should update now. Disclosed March 2026, reported by Lucas Montes (NiRoX).

Vulnerability Overview

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.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Ninja Forms <= 3.14.1 takes an account at Contributor level or above. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Ninja Forms the fix is 3.14.2: builds <= 3.14.1 are affected, anything from 3.14.2 onward is not.

Remediation

Update to version 3.14.2, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Ninja Forms 3.14.2 closes this, and updating the plugin is the step that ends it.
