CVE-2026-34264 (GCVE-0-2026-34264)

Vulnerability from cvelistv5 – Published: 2026-04-14 00:09 – Updated: 2026-04-14 13:14

Title

Information Disclosure vulnerability in SAP Human Capital Management for SAP S/4HANA

Summary

During authorization checks in SAP Human Capital Management for SAP S/4HANA, the system returns specific messages. Due to this, an authenticated user with low privileges could guess and enumerate the content shown, beyond their authorized scope. This leads to disclosure of sensitive information causing a high impact on confidentiality, while integrity and availability are unaffected.

Severity

6.5 (Medium)
