CVE-2023-23941: Insufficient Verification of Data Authenticity

February 3, 2023 (updated February 15, 2023)

SwagPayPal is a PayPal integration for shopware/platform. If JavaScript-based PayPal checkout methods are used (PayPal Plus, Smart Payment Buttons, SEPA, Pay Later, Venmo, Credit card), the amount and item list sent to PayPal may not be identical to the one in the created order. The problem has been fixed with version 5.4.4. As a workaround, disable the aforementioned payment methods or use the Security Plugin in version >= 1.0.21.
