CVE-2026-89110

CRITICAL 9.9

Published 2026-10-13 · Last modified 2026-10-14

SAP NetWeaver Visual Composer does not perform sufficient authorization checks in certain portal functionality. An attacker with low privileges could invoke internal operations on a preconfigured remote system. Depending on the remote connection configuration, this could lead to a full compromise of the remote system. This results in a high impact on confidentiality, integrity and availability.
