Description
The Hungarian Pickup Points & Shipping Labels for WooCommerce plugin for WordPress is vulnerable to Authentication Bypass via the Kvikk webhook (IPN) handler in all versions up to, and including, 4.3. This is due to the ipn_process() function, which runs on every request through the init hook, comparing the X-API-KEY request header loosely against the stored Kvikk API key. When no Kvikk API key is saved, an empty or missing header matches the empty setting. This makes it possible for unauthenticated attackers who know an order's number and its tracking number to send forged webhook requests that remove the shipping label and tracking metadata from that order, provided the site has no Kvikk API key configured.
