CVE-2022-3589Network attack vector

Cross-account data access via manipulated API requests

Published Nov 21, 2022 · Updated Apr 25, 2025

Authorization bypass in the ease2pay API used by Miele appWash allows remote authenticated users to read and partially modify other users' data. The endpoint trusts a user-controlled request value without verifying that the referenced record belongs to the authenticated caller, while insecure session tokens preserve the unauthorized context. A low-privilege account and network access to the cloud API are required; passwords remain protected, and service availability is unaffected.
