Our summary

October 2026 Patch Day (13 October) brought 22 entries: 16 new SAP security notes, 4 GitHub advisories for SAP open-source libraries, and 2 updated notes. Four are rated Critical, led by a CVSS 10.0 SSRF in SAP Cloud SDK for Python and two 9.9 flaws in SAP NetWeaver Visual Composer and SAP S/4HANA. None of this month’s CVEs is in the CISA KEV catalog (16 October 2026 release).

By priority: 4 Critical, 3 High, 14 Medium and 1 Low. Most of the Medium notes are cross-site scripting and missing-authorization fixes in SAP NetWeaver Enterprise Portal, SAPUI5 and the ABAP stack.

Visual Composer is worth extra attention. Two SAP CVEs that CISA added to the KEV catalog in 2025, CVE-2025-31324 and CVE-2025-42999 (notes 3594142 and 3604119), are in the SAP NetWeaver Visual Composer development server. This month’s note 3797111 (CVE-2026-89110, CVSS 9.9) is a broken-access-control issue in SAP NetWeaver Visual Composer (VC70RUNTIME 7.50).

Three of the four GitHub advisories are for developer tooling and libraries (cla-assistant, yeoman-ui, cloud-security-services-integration-library). They are fixed by upgrading the package, not by applying an SAP note.

What to patch first

Ordered by: known exploitation (CISA KEV), then SAP priority, then CVSS. A triage aid, not a substitute for your own risk assessment.
