Sensitive data access via missing authentication check

Published Sep 9, 2025 · Updated Feb 26, 2026

Missing authentication in SAP NetWeaver on IBM midrange systems allows remote authenticated users to read, modify, or delete sensitive data. SAP has not disclosed the affected interface or operation; the public record states only that an authentication check is missing. A high-privilege account is required, and exploitation also exposes administrative functions and can interrupt the application.
