CVE-2026-44756Network attack vector

Unauthenticated code execution via malformed EPP lengths

Published Sep 8, 2026 · Updated Sep 8, 2026

Memory corruption in SAP Extended Passport (EPP) Processing allows remote attackers to execute operating system commands via crafted requests. The shared SAP Kernel library deserializes externally supplied EPP length fields without boundary validation, causing a memory safety violation. EPP parsing occurs before authentication over HTTP, SAP GUI, and RFC paths, so successful exploitation grants control of the receiving SAP process and its data.
