Description
The PayPal Brasil para WooCommerce plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.7.8. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to disable or enable the PayPal Brasil BCDC payment gateway and overwrite its WooCommerce gateway settings, removing PayPal from checkout for all customers.
