What happened
Tenable blog posts (May 2026) highlight a sharp rise in vulnerability exploitation and worsening remediation times: vulnerability exploitation is now the top initial access vector while median time-to-patch has increased. Multiple high-risk, actively exploited vulnerabilities are covered—most notably a critical (CVSS 10.0) authentication bypass in Cisco Catalyst SD-WAN (CVE-2026-20182) being used by a sophisticated actor (UAT-8616) and other clusters, with CISA mandating emergency remediation. Several Linux-kernel local privilege escalations (Dirty Frag: CVE-2026-43284 & CVE-2026-43500; Fragnе
