Summary

CVE	CVE-2026-120017
State	PUBLISHED
Assigner	sap
Source Priority	CVE Program / NVD first with legacy fallback
Published	2026-11-10 01:17:16 UTC
Updated	2026-11-10 01:17:16 UTC
Description	SAP NetWeaver AS ABAP and ABAP Platform does not perform sufficient verification of incoming authentication assertions under certain configurations. An unauthenticated attacker could submit specially crafted data to bypass authentication and impersonate arbitrary users, including privileged accounts. Successful exploitation could cause a full system compromise, with the impact potentially extending to connected components and systems beyond the affected system. This results in a high impact on confidentiality, integrity, and availability of the application.
