CVE-2026-66768
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.
