At a glance

CVE-2025-15510 is a medium-severity Missing Authorization vulnerability in the NEX-Forms WordPress plugin, affecting versions <= 9.1.8. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 9.1.9; sites on affected versions should update now. Disclosed January 2026, reported by Deadbee.

Vulnerability Overview

The NEX-Forms – Ultimate Forms Plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the NF5_Export_Forms class constructor in all versions up to, and including, 9.1.8. This makes it possible for unauthenticated attackers to export form configurations, that may include sensitive data, such as email addresses, PayPal API credentials, and third-party integration keys by enumerating the nex_forms_Id parameter.

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 privileges on the target site, and no interaction from a victim user.

CWE-862: Missing Authorization

Reaching this weakness in NEX-Forms <= 9.1.8 takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For NEX-Forms the fix is 9.1.9: builds <= 9.1.8 are affected, anything from 9.1.9 onward is not.

Remediation

Update to version 9.1.9, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: NEX-Forms 9.1.9 closes this, and updating the plugin is the step that ends it.
