CVE-2026-66768 (GCVE-0-2026-66768)

Vulnerability from cvelistv5 – Published: 2026-09-08 00:11 – Updated: 2026-09-08 10:34

Title

Improper Access Control in SAP NetWeaver (SAP GUI for Java)

Summary

SAP GUI for Java does not correctly enforce the trust level policy for certain functions invoked from a connected backend system. A low-privileged attacker could exploit this weakness by manipulating a connected backend system to trigger affected functionality. This could allow arbitrary command execution on the victim's machine, leading to a high impact on the confidentiality, integrity, and availability of the affected system.
