DHL Shipping label endpoint permits unauthenticated order disclosure
DHL Shipping Germany for WooCommerce before 4.0.1 exposes a shipping-label download endpoint without a login, capability, nonce or order-ownership check. An unauthenticated attacker can enumerate sequential record IDs and download stored labels containing customer names, full postal addresses and order references. This unscored record received deeper review because it provides an unauthenticated sensitive-data disclosure primitive; the CNA does not disclose the endpoint path or parameter name.

Technical description
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.
