CVE-2021-21026Network attack vector

Restricted-resource disclosure via integrations authorization failure

Published Feb 11, 2021 · Updated Sep 16, 2024

Improper authorization in Adobe Commerce 2.4.1 and earlier allows attackers with admin-console access to read restricted resources. Adobe identifies the integrations module as the locus but has not published the affected endpoint, failed authorization check, or input path. Successful exploitation requires access to the admin console and has no reported write or service-interruption impact.
