## Executive Summary

Critical infrastructure vulnerabilities are actively exploited across virtualization, print management, application delivery, and database platforms this quarter. Broadcom has released patches for a CVSS 9.3 integer-overflow flaw in VMware Workstation and Fusion that allows local attackers with elevated privileges to execute arbitrary code on the host [Critical VMware Workstation and Fusion Flaw Lets VM Admins Execute Host Code](https://thehackernews.com/2026/09/critical-vmware-workstation-and-fusion.html). Simultaneously, threat actors are chaining authentication bypass and remote code execution vulnerabilities in PaperCut to target educational institutions in the U.S. and Europe [Attackers Exploit PaperCut Flaws to Steal Credentials From Schools and Universities](https://thehackernews.com/2026/09/attackers-exploit-papercut-flaws-to.html).

Network perimeter defenses face sustained pressure from exploited authentication bypass flaws in Citrix NetScaler appliances [Critical Citrix NetScaler auth bypass now leveraged in attacks](https://www.bleepingcomputer.com/news/security/hackers-target-critical-citrix-netscaler-auth-bypass-in-attacks/) and a twelve-year-old logical decoding vulnerability in PostgreSQL that permits replication-role code execution [PostgreSQL Fixes 12-Year-Old Logical Decoding Flaw Enabling Replication-Role Code Execution](https://thehackernews.com/2026/09/postgresql-fixes-12-year-old-logical.html). These issues affect widely deployed enterprise infrastructure and require immediate patching cycles.

Remote monitoring and management platforms have become a recurring attack surface. N-able has issued four N-central hotfixes in five weeks, with the latest addressing a maximum-severity unauthenticated RCE flaw that the vendor's incident notice indicates has been exploited in the wild [N-able Issues Fourth N-central Hotfix in Five Weeks for Unauthenticated RCE Flaw](https://thehackernews.com/2026/09/n-able-issues-fourth-n-central-hotfix.html) [N-able patches max severity N-central flaw amid ongoing attacks](https://www.bleepingcomputer.com/news/security/n-able-patches-max-severity-n-central-flaw-amid-ongoing-attacks/). ConnectWise has also disclosed a ScreenConnect vulnerability without an immediately available patch, providing only temporary mitigations [ConnectWise warns of new ScreenConnect flaw without patch](https://www.bleepingcomputer.com/news/security/connectwise-warns-of-new-screenconnect-flaw-without-patch/).

Credential theft and session hijacking techniques are evolving beyond traditional phishing. The JSCeal malware demonstrates sophisticated V8 JavaScript compilation with obfuscation techniques to bypass Google authentication using stolen session cookies [JSCeal Malware Can Bypass Google Authentication Using Stolen Session Cookies](https://thehackernews.com/2026/09/jsceal-malware-can-bypass-google.html), while MikroTik router chains are being exploited to hijack devices with exposed SSH services [Hackers exploit new MikroTik RouterOS flaws to hijack routers](https://www.bleepingcomputer.com/news/security/hackers-exploit-new-mikrotik-routeros-flaws-to-hijack-routers/). These developments signal a shift toward post-exploitation persistence and identity-focused attacks.
