CVE-2021-41120 – Unauthorized access to Credit card form in sylius/paypal-plugin

https://notcve.org/view.php?id=CVE-2021-41120

sylius/paypal-plugin is a paypal plugin for the Sylius development platform. In affected versions the URL to the payment page done after checkout was created with autoincremented payment id (/pay-with-paypal/{id}) and therefore it was easy to predict. The problem is that the Credit card form has prefilled "credit card holder" field with the Customer's first and last name and hence this can lead to personally identifiable information exposure. Additionally, the mentioned form did not require authentication. The problem has been patched in Sylius/PayPalPlugin 1.2.4 and 1.3.1. • https://github.com/Sylius/PayPalPlugin/commit/2adc46be2764ccee22b4247139b8056fb8d1afff https://github.com/Sylius/PayPalPlugin/commit/814923c2e9d97fe6279dcee866c34ced3d2fb7a7 https://github.com/Sylius/PayPalPlugin/security/advisories/GHSA-25fx-mxc2-76g7 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-639: Authorization Bypass Through User-Controlled Key •
