Description

The Klarna Checkout for WooCommerce WordPress plugin before 2.13.5 exposes an unauthenticated WooCommerce Ajax endpoint that allows an attacker to flood the log files with data at the maximum size allowed for a POST parameter per request. This can result in rapid consumption of disk space, potentially filling the entire disk.
