## Executive Summary

The September 2026 threat landscape is defined by a surge in actively exploited critical vulnerabilities across widely deployed infrastructure components. CISA has added five actively exploited flaws to its Known Exploited Vulnerabilities catalog, including a critical authorization bypass in JFrog Artifactory (CVE-2026-42016) and issues affecting ConnectWise ScreenConnect and MikroTik RouterOS [CISA Adds 5 Actively Exploited Artifactory, ScreenConnect, and RouterOS Flaws to KEV](https://thehackernews.com/2026/09/cisa-adds-5-actively-exploited.html). Simultaneously, a maximum-severity path traversal vulnerability in GitLab (CVE-2026-85706) poses immediate supply chain risk to both Community and Enterprise Edition instances [Maximum Severity GitLab Flaw Puts Supply Chains at Risk](https://www.darkreading.com/cyberattacks-data-breaches/maximum-severity-gitlab-flaw-supply-chains-risk).
