Summary
The Germanized for WooCommerce plugin for WordPress is vulnerable to Unauthorized Access of Private Data via Activation Token Reuse in versions up to, and including, 4.1.4. This is due to the `on_user_email_changed` hook — which is responsible for rotating the activation token and recording a pending-email-change marker on an unactivated Customer account — only being registered inside the `is_double_opt_in_login_enabled()` branch when "Disable login for unactivated customers" is set to Yes, leaving the original `?activate=` token valid and entirely unbound to the email address it was issued for when that setting is No. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change their account email to a victim's billing email via the standard `/my-account/edit-account/` form and then redeem their original activation token through `customer_account_activate()`, triggering `link_customer_past_orders()` to reassign any matching guest order to the attacker's account and exposing the original buyer's billing name, street address, phone number, and purchased items on the attacker's My Account order page. Exploitation requires the site to have double opt-in enabled with "Disable login for unactivated customers" explicitly set to No (a non-default configuration), public customer registration enabled, and the original activation token redeemed within its one-day expiry window.
