CVE-2023-23941Network attack vector

Payment data tampering via unverified checkout details

Published Feb 3, 2023 · Updated Mar 10, 2025

Insufficient data verification in Shopware SwagPayPal before 5.4.4 allows remote attackers to alter PayPal order amounts and items. Shopware has not published the faulty code locus; affected JavaScript checkout methods can send PayPal an amount or item list that differs from the created order. Exposure requires PayPal Plus, Smart Payment Buttons, SEPA, Pay Later, Venmo, or credit-card checkout, and the consequence is payment-data integrity loss.
