SAP Commerce Cloud CVE-2026-58231 Targeted in Exploitation Attempts Days After Patch

A maximum-severity (CVSS 10.0) unauthenticated RCE flaw in SAP Commerce Cloud, CVE-2026-58231, is under active exploitation days after patching.

CVE-2026-58231, rated 10.0 on CVSS, stems from insufficient authorization checks and input validation in SAP Commerce Cloud, enabling unauthenticated arbitrary code execution. Defused Cyber's honeypots detected exploitation attempts three days after the patch, and KEVIntel independently confirmed two attempts on August 14 from a US IP address. Onapsis urges customers to patch and rebuild, with an IP Filter Set offered as a temporary workaround. No actor attribution yet, though prior SAP NetWeaver flaw CVE-2025-31324 was exploited by China-nexus and criminal groups.

VU#369611: ExLlamaV3 contains Denial of Service vulnerability via insufficient bounds checking on kernel dispatch index

CERT/CC details CVE-2026-84286, an out-of-bounds memory access in ExLlamaV3's CUDA extension causing denial-of-service crashes; fixed via merged pull request.

CERT/CC published VU#369611 for CVE-2026-84286, an out-of-bounds memory access in the exllamav3_ext CUDA extension of the ExLlamaV3 LLM inference library. A crafted input with kernel parameter K set to 0 produces a negative index into a fixed 24-entry kernel dispatch array, causing a CUDA illegal memory access and denial-of-service crashes. The vendor fixed the issue in the main repository via pull request #310, and maintainers of 49 downstream projects, including ezexl3 and MawDiscord, are advised to rebuild against the patched version. The issue was reported by Nathan Keys and impact is limited to crashes and instability, not code execution.

CVE-2026-89775: Guest-to-Host Escape in KVM/arm64

Disclosed CVE-2026-89775 lets a guest VM escape to the host on KVM/arm64 systems with nested virtualization enabled.

Researcher Hyunwoo Kim disclosed CVE-2026-89775, a guest-to-host escape in KVM/arm64, after the embargo agreed with linux-distros maintainers expired. The root cause is a type truncation of the stage-1 walk level that makes a size computation return 0, the value meaning 'size unknown'. The VNCR pseudo-TLB invalidation path then interprets that 0 as a valid value on ARM64 hosts where nested virtualization is enabled.

2026-011: Critical Vulnerabilities in SAP Kernel and NetWeaver Message Server

SAP patched two critical flaws, OVERPASS (CVE-2026-44756, CVSS 10.0) and S4GET (CVE-2026-58240), allowing unauthenticated attackers to execute OS commands on SAP hosts.

On SAP's September 2026 Security Patch Day, SAP released Security Notes 3747649 and 3759472 fixing two critical unauthenticated remote vulnerabilities found by Onapsis. CVE-2026-44756 ('OVERPASS', CVSS 10.0) is a memory corruption flaw in Extended Passport (EPP) deserialisation in the SAP Kernel; CVE-2026-58240 ('S4GET', CVSS 9.8) is a missing authentication check in the NetWeaver Message Server that lets attackers register as trusted cluster nodes. Successful exploitation of either can yield OS command execution as the SAP service account, leading to full system and business data compromise, and CERT-EU urges immediate patching. No in-the-wild exploitation is reported.

Windows Remote Desktop Client Vulnerability Allows Attackers to Execute Remote Code

CERT/CC published VU#943094 for a server-side request forgery in Ascensio System SIA's ONLYOFFICE ownCloud integration plugin version 9.12, tracked as CVE-2026-84282. The /apps/onlyoffice/ajax/settings/address endpoint does not validate the user-supplied document server URL, so an authenticated administrator can make the ownCloud server send arbitrary requests to localhost and internal hosts.
