CVE-2026-0509Network attack vector

Authenticated RFC execution via missing authorization check

Published Feb 10, 2026 · Updated Feb 10, 2026

Missing authorization in SAP NetWeaver AS ABAP and ABAP Platform allows remote authenticated users to execute background RFCs. The background RFC processing path omits the required S_RFC authorization check in cases SAP has not publicly identified. Low-privileged accounts can therefore invoke unauthorized remote functions that alter application state or interrupt service, while confidentiality is unaffected.
