About this tag
The CISA KEV tag covers CISA's Known Exploited Vulnerabilities Catalog, which lists actively exploited flaws that federal agencies and private defenders must prioritize. Recent threads highlight vulnerabilities in Splunk, Joomla, Cisco SD-WAN, Oracle PeopleSoft, Ivanti Sentry, Chromium, Arista EOS, AI LiteLLM, Check Point VPN, and SolarWinds Serv-U. Common themes include missing authentication, command injection, path traversal, and resource exhaustion bugs in enterprise infrastructure, edge devices, and AI tools. For WindowsForum readers, these updates emphasize patching discipline across mixed environments, where flaws in monitoring platforms, VPNs, and management planes can become beachheads for attackers.
