Oracle Critical Security Update – 673 Vulnerabilities Patched Across Product Families

Oracle's September 2026 Critical Patch Update ships 673 patches across 17 product families, including 100+ critical and 240+ remotely exploitable flaws.

Oracle's September 2026 Critical Security Patch Update ships 673 patches covering 672 unique CVEs, with more than 130 additional CVEs resolved through bundled fixes, pushing the effective total past 800. Over 100 flaws are critical severity and more than 240 are remotely exploitable without authentication. Oracle E-Business Suite received 159 fixes, Fusion Middleware 153 (78 unauthenticated and network-exploitable), and Hyperion 102. No in-the-wild exploitation of these specific flaws is reported, but Oracle cites CISA's earlier 72-hour remediation order for actively exploited CVE-2026-21962 (CVSS 10.0).

CISA tells operators to harden Siemens S7 PLCs. Here’s how to do it without disrupting production

CISA, NSA, FBI and other agencies warn of active targeting of internet-exposed Siemens S7 PLCs and urge patching, exposure removal and hardening.

Joint advisory AA26-231A from the NSA, CISA, FBI, Department of Energy and EPA warns that actors are actively targeting Siemens S7 PLCs using internet scanning, AI-assisted scripts and libraries such as Snap7 and python-snap7 over S7comm on TCP port 102. The advisory covers S7-200 through S7-1500 series controllers and recommends patching, removing internet exposure, access controls, monitoring and disabling unneeded services. Siemens states no new S7 vulnerabilities are involved, only misconfigurations addressed in existing ProductCERT guidance SSB-104599. The article details how to apply each measure without breaking production dependencies such as remote I/O, HMI links and diagnostics.

US agencies warn of AI-powered attacks on Siemens industrial controllers

NSA, CISA, FBI, DOE, and EPA warn threat actors use AI-assisted scripts and snap7 libraries to access internet-exposed Siemens S7 PLCs in critical infrastructure sectors.

NSA, CISA, FBI, DOE, and EPA issued a joint advisory warning that threat actors combine open-source snap7.dll/python-snap7 libraries with AI-generated scripts to gain read/write access to Siemens S7-200 through S7-1500 PLCs over the S7comm protocol. Actors use Censys and ZoomEye to find internet-exposed devices and abuse default or weak credentials, with activity assessed as persistent reconnaissance and positioning for future write operations. Agencies urge device inventory, patching, removing PLCs from the internet, and hardening; the pattern resembles Iran-linked CyberAv3ngers targeting of Rockwell, Schneider, and Siemens PLCs.
