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.
