## What is CVE-2026-4094?

CVE-2026-4094 is a high-severity missing authorization vulnerability in realmag777 FOX – Currency Switcher Professional for WooCommerce, published on 15 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.

Weakness: CWE-862 (Missing Authorization)
