The Top 10 Vulnerabilities Threat Actors Exploited Most in 2026

This article explains why many "top exploited vulnerability" lists still include older CVEs, argues that CVSS alone is an insufficient prioritization metric, and recommends prioritizing vulnerabilities using CISA's KEV and EPSS. It highlights rapid real-world exploitation examples (ZeroLogon, Log4Shell, CVE-2026-56164, CVE-2026-8451) and positions ThreatMon's Attack Surface Management as a way to discover exposed assets, identify vulnerable technologies, prioritize based on exposure and asset importance, and reduce the window of exposure.
