Advisory
Source description from Wordfence Intelligence.
The Klarna Checkout for WooCommerce plugin for WordPress is vulnerable to Denial of Service in all versions up to, and including, 2.13.4. This is due to kco_wc_log_js() function not restricting the size of the debug log. This makes it possible for unauthenticated attackers to fill up the log, potentially filling up the disk space and leading to a denial of service.
