SAP's November 10 Security Patch Day includes 35 new security notes, four GitHub advisories and three updates to earlier notes. The release addresses vulnerabilities across SAP business platforms and developer components.
Four flaws carry SAP's maximum CVSS score of 10.0: CVE-2026-76964 in NetWeaver AS ABAP's Internet Communication Manager, CVE-2026-89126 in Web Dispatcher, CVE-2026-89103 in Gateway, and CVE-2026-120017 in the SAML2 Service Provider. These cover memory corruption, broken access control and missing authentication. Other fixes address code injection and additional risks.
MS-ISAC advisory 2026-128 reports no known exploitation in the wild as of November 10. That is not evidence that exploitation is impossible; the advisory warns that the most severe issues could allow code execution and full system compromise.
Organizations should inventory affected SAP components, match installed releases to the vendor's individual security notes, and prioritize the applicable patches after appropriate testing. Do not treat this summary as a universal version list. Restrict administrative access, use least privilege and network segmentation, and verify remediation with vulnerability scanning.
