At a glance

CVE-2026-4094 is a high-severity Missing Authorization vulnerability in the FOX WordPress plugin, affecting versions <= 1.4.5. It carries a CVSS score of 8.1 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 1.4.6; sites on affected versions should update now. Disclosed May 2026, reported by Ren Voza.

Vulnerability Overview

The FOX – Currency Switcher Professional for WooCommerce plugin for WordPress is vulnerable to unauthorized data loss due to a missing capability check on the 'admin_head' function in all versions up to, and including, 1.4.5. This makes it possible for authenticated attackers, with Contributor-level access and above, to delete the entire multi-currency configuration by visiting any wp-admin page with the `woocs_reset` parameter appended. Additionally, because no nonce is verified, this is also exploitable via Cross-Site Request Forgery against any administrator. The vulnerability may also be exploited by Subscriber-level users if the site is configured to allow Subscriber access to 'wp-admin' pages.

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 integrity, availability.

CWE-862: Missing Authorization

FOX <= 1.4.5 carries this weakness at admin_head, and reaching it takes an account at Contributor level or above. 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 FOX the fix is 1.4.6: builds <= 1.4.5 are affected, anything from 1.4.6 onward is not.

Remediation

Update to version 1.4.6, 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: FOX 1.4.6 closes this, and updating the plugin is the step that ends it.
