Helloprint <= 2.1.2 - Missing Authorization to Unauthenticated Arbitrary Order Status Modification

Missing Authorization
CVE CVE-2025-13666
CVSS Medium (5.3)
Publicly Published December 5, 2025
Last Updated December 6, 2025
Researcher Md. Moniruzzaman Prodhan (NomanProdhan)
Description

The Helloprint plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 2.1.2. This is due to the plugin registering a public REST API endpoint without implementing authorization checks to verify request authenticity. This makes it possible for unauthenticated attackers to arbitrarily modify WooCommerce order statuses via the /wp-json/helloprint/v1/complete_order_from_helloprint_callback endpoint by providing a valid order reference ID.
