Authenticated data modification via unchecked OData operations
Published Apr 14, 2026 · Updated Apr 14, 2026
Missing authorization in SAP S/4HANA OData Service S4CORE 109 allows remote authenticated users to update or delete child entities. The exposed Manage Technical Object Structures OData operations process update and delete requests without enforcing required authorization checks. A valid low-privilege session and network access are required; the flaw alters technical-object data but does not disclose data or interrupt service.
