SAP Security Patch Day – Critical SAP NetWeaver, Dispatcher and Gateway Vulnerabilities Patched
SAP November 2026 patch day fixes four CVSS 10.0 vulnerabilities in NetWeaver, Dispatcher, and Gateway.
SAP released its November 2026 Security Patch Day on November 10, addressing 35 new security notes including four maximum-severity (CVSS 10.0) vulnerabilities in NetWeaver, Web Dispatcher, Gateway, and SAML2 Service Provider. The critical flaws include unauthenticated memory corruption, broken access control, and missing authentication issues that could allow arbitrary code execution.

The lesson from this incident
Full lessonSAP's November 2026 Patch Day revealed four maximum-severity (CVSS 10.0) vulnerabilities across core enterprise components including NetWeaver, Web Dispatcher, and Gateway — flaws that allow unauthenticated memory corruption and arbitrary code execution without any credentials. This matters because SAP systems routinely house the most sensitive business data in an organization, and unauthenticated remote code execution represents a complete perimeter bypass. Attackers actively scan for unpatched SAP instances, meaning the window between patch release and exploitation attempts is extremely narrow. Organizations running kernel versions 7.53 through 9.20 that delay patching are leaving their most critical ERP infrastructure exposed to full system compromise.
