The ECPay Ecommerce for WooCommerce plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'clear_ecpay_debug_log' AJAX action in all versions up to, and including, 1.1.2411060. This makes it possible for authenticated attackers, with Subscriber-level access and above, to clear the plugin's log files.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
