DHL eCommerce Benelux for WooCommerce Unauthorized Label Modification Vulnerability
The DHL eCommerce (Benelux) for WooCommerce plugin for WordPress is vulnerable to unauthorized modification and loss of data due to a missing capability check and missing nonce verification on the create_label() and delete_label() functions in versions up to, and including, 2.2.3. These functions are wired to the wp_ajax_dhlpwc_label_create and wp_ajax_dhlpwc_label_delete hooks and act on an attacker-supplied post_id (WooCommerce order ID). This makes it possible for authenticated attackers, with Subscriber-level access and above, to create or delete DHL shipping labels associated with any WooCommerce order on the site.
Quick answer
DHL eCommerce (Benelux) for WooCommerce should be reviewed and updated if it matches the affected versions. The recommended fix is to apply the vendor-supported patched version or the mitigation steps below, then retest the public website with Fixnx.

How to fix it
DHL eCommerce (Benelux) for WooCommerce is affected by CVE-2026-9235.

Update or disable the plugin first on public WordPress and WooCommerce sites.
- Inventory every WordPress site where DHL eCommerce (Benelux) for WooCommerce is installed and enabled.
- Update DHL eCommerce (Benelux) for WooCommerce beyond the affected version 2.2.3 when a vendor-fixed release is available.

- Restrict the vulnerable AJAX or REST actions with WAF rules until the plugin is patched.
- Review WordPress, WooCommerce, and plugin logs for suspicious requests targeting the affected action or order/job/quote identifiers.
