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 getvalue() function in classes/fixed/fixeduserrole.php trusting the attacker-controlled $REQUEST['woocorderuserroles'] 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.

The FOX – Currency Switcher Professional for WooCommerce plugin for WordPress is vulnerable to unauthorized data loss due to a missing capability check on the 'adminhead' 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 woocsreset 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.

The FOX – Currency Switcher Professional for WooCommerce plugin is vulnerable to Unauthenticated Arbitrary Shortcode Execution in versions up to, and including, 1.4.1.8. This allows unauthenticated attackers to execute arbitrary shortcodes. The severity and exploitability depends on what other plugins are installed and what shortcode functionality they provide.
