Authorization Bypass in SAP S/4HANA Draft Operations

Executive Summary

CVE-2026-44771 is a vulnerability in SAP S/4HANA where the Draft operation does not perform necessary authorization checks for an authenticated user. This means that a restricted user could access information within the entity that they should not have access to, leading to an escalation of privileges.

The vulnerability specifically results in a low impact on confidentiality, meaning unauthorized users may view sensitive data. However, it does not affect the integrity or availability of the application.

Compliance Impact

This vulnerability could affect compliance with regulations that mandate strict access controls and protection of sensitive data, such as GDPR and HIPAA.

• GDPR: Unauthorized access to personal data due to insufficient authorization checks may violate GDPR requirements for data protection and confidentiality. Organizations could face penalties if they fail to secure personal data adequately.
• HIPAA: If the exposed data includes protected health information (PHI), this vulnerability could lead to non-compliance with HIPAA's Privacy and Security Rules, which require strict access controls to safeguard patient data.

Organizations using SAP S/4HANA should assess whether the affected data falls under these regulations and take corrective actions to mitigate risks.
