- CVE-2026-9241, 28 May 2026
- The FOX - Currency Switcher Professional for WooCommerce plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in all versions up to and including 1.4.6. This is due to the `get_value()` function in `classes/fixed/fixed_user_role.php` trusting the attacker-controlled `$_REQUEST['wooc_order_user_roles']` parameter to determine the user's role context for role-based price resolution without any validation, allowing it to override the legitimate role data derived from the authenticated user's session object via `$user->roles`. This makes it possible for authenticated attackers, with Subscriber-level access and above, to impersonate higher-privileged roles - such as wholesale customer or administrator - and obtain discounted or otherwise restricted pricing that should not be available to their actual role. This vulnerability only has practical impact when the fixed user-role pricing feature is enabled and at least one product has a privileged-role price configured. CVE record
- CVE-2026-4094, 15 May 2026
- 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. CVE record
- CVE-2024-8271, 14 Sep 2024
- The The FOX - Currency Switcher Professional for WooCommerce plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 1.4.2.1. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode in the 'woocs_get_custom_price_html' function. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. CVE record
- CVE-2023-6556, 11 Jan 2024
- The FOX - Currency Switcher Professional for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via currency options in all versions up to, and including, 1.4.1.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record

- The WOOCS WordPress plugin before 1.3.7.1 does not sanitise and escape the key parameter of the woocs_update_profiles_data AJAX action (available to any authenticated user) before outputting it back in the response, leading to a Reflected cross-Site Scripting issue CVE record
What to do if you run FOX
If you run FOX, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
