CVE-2026-16981: CWE-639 Authorization Bypass Through User-Controlled Key in DHL Shipping Germany for WooCommerce
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.
AI Analysis
Technical Summary
CVE-2026-16981 is an authorization bypass vulnerability (CWE-639) in the DHL Shipping Germany for WooCommerce WordPress plugin versions prior to 4.0.1. The plugin fails to perform any authorization checks—such as capability verification, nonce validation, login status, or ownership checks—on a shipping-label download endpoint. This allows unauthenticated attackers to enumerate sequential identifiers and download all stored shipping labels, exposing customers' personally identifiable information.
Potential Impact
An unauthenticated attacker can access and download shipping labels for all orders processed by the vulnerable plugin. Each label contains sensitive customer data including full names, complete postal addresses, and order references. This exposure risks customer privacy and may lead to further targeted attacks or identity theft.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix or update is released, restrict access to the affected endpoint through web server configuration or other access control mechanisms to prevent unauthorized downloads.
