GoHero Store Customizer for WooCommerce <= 3.5 - Missing Authorization to Unuthenticated Settings Update

The GoHero Store Customizer for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the wooh_action_settings_save_frontend() function in all versions up to, and including, 3.5. This makes it possible for unauthenticated attackers to update limited plugin settings.
