Description
The PAYCOMET for WooCommerce plugin for WordPress is vulnerable to unauthorized modification and deletion of data via the card tokenization payment notification (wc-api=woocommerce_paytpv, tpvLstr=notify) in all versions up to, and including, 5.45, due to the notification hash check being skipped for execute_purchase notifications whose Order value contains '_tokenization'. This makes it possible for unauthenticated attackers to delete any customer's saved payment card by its ID, attach attacker-supplied PAYCOMET user tokens to that customer's account, and overwrite the stored payment tokens of subscription orders that used the card.
