CVE-2020-28199Public exploitNetwork attack vector

Unauthenticated credential disclosure via JSON response

Published Feb 26, 2021 · Updated Aug 4, 2024

Information disclosure in Amazon Pay Plugin before 9.4.2 for Shopware allows remote attackers to read the merchant Amazon Secret Access Key via JSON. The plugin adds the secret to a JSON response when the Enlight_Controller is used because a required authorization check is missing. Exploitation requires the JSON renderer and another plugin combination that reaches this controller; exposure compromises the credential's confidentiality and can enable unauthorized Amazon Pay activity.
