CVE-2026-120017

Missing Authentication in SAP NetWeaver AS ABAP and ABAP Platform (SAML2 Service Provider)

Published Nov 10, 2026 CVSS 3.1 · 10 Critical EPSS < 1% KEV · Not listed

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.
