Threat database

Payment Plugins for Stripe WooCommerce versions up to and including 4.0.17 are vulnerable to a reflected cross-site scripting (XSS) flaw via the '#response' URL fragment. This vulnerability arises from insufficient input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary scripts that execute when a user visits the crafted page. Exploitation depends on the 'Generic Errors' setting being unchecked, which causes raw Stripe error messages to be returned without sanitization.

The Payment Plugins for Stripe WooCommerce plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.0.7. 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 mark arbitrary pending asynchronous WooCommerce orders as paid by forging a charge.pending event with attacker-controlled metadata.order_id, metadata.gateway_id, and a charge object carrying status=succeeded and captured=true, triggering payment_complete() and downstream fulfillment flows with an attacker-supplied transaction ID. Exploitation requires the merchant to have left the webhook_secret_test or webhook_secret_live option blank, which is the plugin's default state until a Stripe-issued whsec_ value is manually configured; once a non-empty secret is set, the signature verification cannot be bypassed.

The Payment Plugins Braintree For WooCommerce plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the wc-braintree/v1/3ds/vaulted_nonce REST API endpoint in all versions up to, and including, 3.2.78. This is due to the endpoint being registered with permission_callback set to __return_true and processing user-supplied token IDs without verifying ownership or authentication. This makes it possible for unauthenticated attackers to retrieve payment method nonces for any stored payment token in the system, which can be used to create fraudulent transactions, charge customer credit cards, or attach payment methods to other subscriptions.
