## Overview

SAP S/4HANA does not perform sufficient instance-level authorization checks for certain modification operations on associated business object data. An attacker with low privileges and local access to the system could bypass authorization checks to modify data belonging to objects they are not authorized for. This results in a high impact on integrity. There is no impact on confidentiality and availability.
