CVE-2021-21012Network attack vector

Sensitive information disclosure via checkout object reference

Published Jan 13, 2021 · Updated Sep 16, 2024

Insecure direct object reference in Adobe Commerce checkout in 2.4.1 and earlier allows remote authenticated users to read sensitive data. Adobe identifies the checkout module and user-controlled object reference, but has not published the affected request, code locus, or missing ownership check. A non-administrative account is sufficient, and impact is limited to unauthorized access to restricted checkout resources.
