DescriptionCVE.org

The Payment Plugins for PayPal WooCommerce WordPress plugin before 2.0.27 does not verify that a PayPal order supplied in a payment request belongs to the WooCommerce order being paid unless that PayPal order has already been completed, allowing unauthenticated attackers to have another buyer's approved but uncaptured payment captured against an order of their own.

AnalysisAI

Unauthenticated attackers can capture another buyer's approved-but-uncaptured PayPal payment against a WooCommerce order of their own choosing in Payment Plugins for PayPal WooCommerce versions before 2.0.27. The plugin fails to confirm that the PayPal order supplied in a payment request actually belongs to the WooCommerce order being paid unless that PayPal order is already completed, so any store running the vulnerable plugin with the PayPal gateway active is exposed. …
