WOOCS – WooCommerce Currency Switcher <= 1.4.2.1 is vulnerable to Unauthenticated Arbitrary Shortcode Execution vulnerability

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.
