Description
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.
