Executive Summary

The PAYCOMET for WooCommerce WordPress plugin before version 5.46 has a flaw where it does not check cryptographic signatures on its payment notification endpoint during tokenization operations. This allows unauthenticated attackers to overwrite stored payment tokens linked to existing orders and delete saved card records.

Detection Guidance

Check the installed version of the PAYCOMET for WooCommerce plugin. If it is between 5.36 and 5.45, the system is vulnerable. Use WordPress admin panel or run the command: wp plugin list --name=paycomet-for-woocommerce to verify the version.
