• CVE-2026-4475610.0<1%
  Unauthenticated buffer overflow in SAP Kernel Extended Passport (EPP) processing
  CVE-2026-44756 is a critical (CVSS 10.0) memory-safety flaw — a classic buffer overflow (CWE-120) — in the Extended Passport Protocol (EPP) processing library of SAP Kernel, the core runtime underlying SAP NetWeaver components (SAP's advisories tie the issue to SAP Kernel and the NetWeaver Message Server). An unauthenticated remote attacker can trigger it by sending a crafted network request containing a malformed EPP header to a system that processes EPP traffic. The malformed header causes undefined behavior and abnormal program termination, and SAP's maximum-severity rating plus vendor coverage of the flaw indicate it can enable unauthenticated remote code execution with high impact on confidentiality, integrity, and availability. Any organization running the affected SAP Kernel/NetWeaver components — essentially typical ABAP-stack SAP deployments — is exposed until patched. No public proof-of-concept is known, the flaw is not in CISA KEV, EPSS estimates only a 0.3% chance of exploitation within 30 days (25th percentile), and fixes shipped in SAP's September 2026 Security Patch Day.

• CVE-2026-582409.8<1%
  Unauthenticated Component Registration Flaw in SAP NetWeaver Message Server
  SAP NetWeaver Message Server does not sufficiently validate the authenticity of internal application server components when they register with the service (CWE-308). An unauthenticated attacker with network access to the affected service can send a crafted registration request to add or impersonate an application server component. Once registered, the attacker can potentially perform unauthorized actions within the SAP application environment, resulting in a high impact on confidentiality, integrity, and availability — reflected in the critical CVSS 9.8 score. Any organization running SAP NetWeaver deployments that rely on the Message Server is affected; the source data does not specify exact affected version ranges. There is no evidence of active exploitation, no public proof-of-concept, and the issue is not in CISA KEV, with EPSS assigning only a ~0.3% 30-day exploitation probability; a fix shipped in SAP's September 2026 Security Patch Day (a release that also patched other critical flaws, including the separately reported 'OVERPASS' SAP Kernel issue).

• CVE-2026-769699.4<1%
  Unauthenticated Credential Theft and Tenant Data Tampering in SAP @sap/cds-mtxs
  CVE-2026-76969 is a critical flaw (CVSS 9.4) in SAP's @sap/cds-mtxs npm package, the multitenancy component of the SAP Cloud Application Programming Model (CAP), which performs insufficient checks on certain functionality used in multitenant CAP applications with extensibility enabled. An unauthenticated attacker who can reach the affected endpoints can send specially crafted requests that cause the service to disclose sensitive credentials. With those credentials, the attacker can replace or delete tenant data, resulting in high impact to integrity and availability and partial impact to the confidentiality of business data. Only deployments running multitenant CAP applications on @sap/cds-mtxs with extensibility enabled are affected. Exploitation has not been observed: there is no known public proof of concept, the issue is not in CISA KEV, and EPSS estimates only a ~0.3% probability of exploitation within 30 days.

  Trust Level Policy Bypass Enables RCE in SAP GUI for Java
  SAP GUI for Java (CWE-807) fails to correctly enforce its trust level policy when certain functions are invoked from a connected backend system, meaning the client relies on untrusted backend input when making security decisions. To exploit it, an attacker needs low-privileged access to a connected backend (for example, a compromised or malicious SAP backend) and must manipulate that backend to trigger the affected functionality, which also requires interaction from the logged-in user (CVSS UI:R). Successful exploitation yields arbitrary command execution on the victim's workstation, with the changed-scope vector (S:C) allowing a backend-level foothold to break out onto the end-user machine and seriously impacting its confidentiality, integrity, and availability. Anyone running SAP GUI for Java to connect to SAP backends is exposed, particularly in scenarios where less-trusted or low-privileged users can influence the backend their colleagues connect to. There is no known public proof-of-concept, the flaw is not in CISA KEV, and EPSS estimates only a 0.3% chance of exploitation in the next 30 days, so no in-the-wild exploitation is currently known; a fix shipped as part of SAP's September 2026 security patch day.

• CVE-2026-819637.8<1%
  Local Privilege Escalation via Link Following in Windows Update Stack
  CVE-2026-81963 is a link-following flaw (CWE-59, improper link resolution before file access) in the Microsoft Windows Update Stack, in which the component fails to correctly resolve file links before opening them. A local attacker with low privileges can plant or manipulate a link (symlink/junction) that the privileged update stack follows during operation, redirecting its file access to an attacker-controlled target. The result is local privilege escalation — CVSS 3.1 rates this 7.8 (high) with high confidentiality, integrity, and availability impact — allowing an authorized local user or malware already on the machine to gain elevated rights. Affected products are Windows 11 23H2, 24H2, 25H2, and 26H1 and Windows Server 2025; any unpatched system on those versions is exposed to any local account holder. The flaw was fixed in Microsoft's record September 2026 Patch Tuesday (974 CVEs), was added to CISA's KEV on 2026-09-08 as one of two Windows zero-days reported as exploited in the wild, and has no known public PoC or confirmed ransomware use.

• CVE-2026-858807.8<1%
  Heap-Based Buffer Overflow in Windows ALPC Enables Local Privilege Escalation
  CVE-2026-85880 is a heap-based buffer overflow in Windows Advanced Local Procedure Call (ALPC), the Windows mechanism for local inter-process communication. An authorized local attacker can trigger the overflow by submitting crafted input over ALPC, corrupting heap memory in the component that handles the request. Successful exploitation allows the attacker to execute code with elevated privileges, typically gaining SYSTEM-level control of the local host, which is especially valuable as a post-exploitation or sandbox-escape step. Affected products include Windows 10 (1607, 1809, 21H2, 22H2) and Windows Server 2012, 2016, 2019, and 2022, meaning most on-premises Windows estates are in scope. The flaw was fixed in Microsoft's record 974-CVE September 2026 Patch Tuesday and was added to CISA's KEV on 2026-09-08, confirming exploitation in the wild; press reports describe Windows zero-days being chained with a Chrome zero-day in 'BlueMoon' kit attacks, though the data does not explicitly confirm this CVE is the Windows flaw in that chain.
