CVE-2026-16981

DHL for WooCommerce < 4.0.1 - Unauthenticated Shipping Label Download via IDOR

The DHL Shipping Germany for WooCommerce WordPress plugin before 4.0.1 does not perform any authorization check (no capability, nonce, login, or ownership check) on one of its shipping-label download endpoints, so an unauthenticated attacker can enumerate sequential ids and download every stored shipping label, each containing the customer's full name, complete postal address, and order reference.
