At a glance

CVE-2025-67579 is a medium-severity Missing Authorization vulnerability in the WordPress User Extra Fields WordPress plugin, affecting versions <= 16.8. 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 16.9; sites on affected versions should update now. Disclosed December 2025, reported by Phat RiO.

Vulnerability Overview

The WordPress User Extra Fields plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 16.8. This makes it possible for unauthenticated attackers to perform an unauthorized action.

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 WordPress User Extra Fields <= 16.8 takes a caller who can reach the endpoint. 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 WordPress User Extra Fields the fix is 16.9: builds <= 16.8 are affected, anything from 16.9 onward is not.

Remediation

Update to version 16.9, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: WordPress User Extra Fields 16.9 closes this, and updating the plugin is the step that ends it.
