SAP Patches CVSS 10.0 Kernel Flaw Enabling Unauthenticated Remote Code Execution
SAP patched CVE-2026-44756 (CVSS 10.0), an unauthenticated kernel memory corruption allowing OS command execution, plus three other critical flaws.
SAP's September security updates include CVE-2026-44756 (OVERPASS, CVSS 10.0), a missing boundary validation during deserialization of Extended Passport (EPP) data in the SAP kernel, enabling unauthenticated attackers to run arbitrary OS commands with SAP administrative privileges. Also patched: CVE-2026-58240 (S4GET, CVSS 9.8), a missing authentication check in SAP NetWeaver Message Server yielding RCE as <sid>adm; CVE-2026-76969 (9.4), credential disclosure in SAP Cloud Application Programming Model multi-tenant apps; and CVE-2026-66768 (9.0), improper access control in SAP NetWeaver SAP GUI for Java. Onapsis, which discovered the flaws, says none have been exploited to date and recommends prioritizing internet-facing SAP systems.

Microsoft Patches Severe Entra ID Flaw (CVSS 10.0) Allowing Remote Code Execution
Microsoft patched CVE-2026-69836 (CVSS 10.0), a deserialization RCE in Entra ID; the flaw was fully mitigated service-side and was not exploited in the wild.
Microsoft disclosed CVE-2026-69836, a CVSS 10.0 remote code execution flaw in Entra ID caused by deserialization of untrusted data, and said the issue was fully mitigated on the service side with no customer action required. The security bulletin initially marked the flaw as exploited, but Microsoft corrected the status to not exploited in the wild on August 21, 2026. Microsoft credited principal security engineer Robert Fitzpatrick with the discovery. The article also recalls the Lazarus Group's exploitation of Windows WinSock AFD zero-day CVE-2026-68820 (CVSS 7.0) in the Operation Dream Job campaign.

Critical ArangoDB Bugs Expose Entire Databases and Enable Remote Code Execution as Root
Two critical ArangoDB flaws (CVSS 9.8/9.9) allow unauthenticated API access and root-level code execution; fixed in 3.12.11.
Remedio researchers reported two critical ArangoDB flaws on August 23, 2026: an authentication bypass via URL-encoded underscores (%5f) in path parsing (GHSA-rrgq-978q-36mq, CVSS 9.8) and a task-execution flaw where a client-controlled isSystem flag lets JavaScript run in the internal context (GHSA-rvhw-4hpw-9vrx, CVSS 9.9). Chained, they allow unauthenticated database access, theft of root password hashes, and root-level code execution when arangod runs as root, such as in the official container image. Patches shipped August 31 in ArangoDB 3.12.11, with GitHub Security Advisories published September 6; CVE identifiers were pending at disclosure time.

Cisco Nexus 9000 Series Switches Silicon One Remote Code Execution Vulnerability
Cisco patches unauthenticated RCE in Nexus 9000 Silicon One switches exposed via TCP ports 43210 and 43211 in the default L3 VRF.
Cisco disclosed and patched a vulnerability in the Silicon One integration for Nexus 9000 Series switches that allows an unauthenticated remote attacker to execute code with root privileges. The flaw stems from TCP ports 43210 and 43211 being accessible in the default Layer 3 VRF. Exploitation can also crash the S1HAL process and force an affected device to reload. Cisco has released software updates, and workarounds are available to mitigate exposure.
