CVE-2024-3047Network attack vector

Unauthenticated internal-service access via attacker-selected destinations

Published May 2, 2024 · Updated Apr 8, 2026

Server-side request forgery in PDF Invoices & Packing Slips for WooCommerce 3.8.0 and earlier allows remote attackers to reach internal services. The transform() function turns an attacker-selected location into a server-originated web request without restricting the destination to external resources. No authentication is required, and the resulting request can query or modify internal services reachable from the WordPress host.
