CISA Known Exploited Vulnerabilities (KEV)
To support the cybersecurity community and help network defenders stay ahead of active threat activity, CISA publishes cisa alert today updates and maintains the authoritative catalog of known exploited vulnerabilities. This KEV database highlights vulnerabilities that have been actively used in real-world attacks, making it an essential resource for security teams aiming to strengthen their defenses.
Organizations should incorporate the KEV catalog into their vulnerability management prioritization framework to ensure they address high-risk issues efficiently and stay aligned with the latest threat intelligence. With frequent updates — including entries marked as cisa kev added today — the catalog enables teams to react quickly to emerging exploitation trends. To streamline monitoring and improve response time, CVEfeed.io provides the freshest CISA KEV additions, delivering real-time visibility into newly identified exploited vulnerabilities and helping organizations maintain accurate, up-to-date security postures.
