What is CVE-2025-13666?
The Helloprint plugin for WordPress is affected by a security flaw that allows unauthenticated users to exploit a public REST API endpoint. In versions 2.1.2 and earlier, the plugin lacks proper authorization checks, making it vulnerable to unauthorized modifications of WooCommerce order statuses. Attackers can manipulate order statuses by sending requests to the /wp-json/helloprint/v1/complete_order_from_helloprint_callback endpoint using a valid order reference ID.
