CISA Known Exploited Vulnerabilities (KEV)
CISA's Known Exploited Vulnerabilities (KEV) catalog is the authoritative list of security flaws that have been confirmed exploited in real-world attacks. CVEFeed.io mirrors every entry, joins it to full CVE and severity data, and tracks new additions so you can prioritize remediation the moment a vulnerability enters the catalog.
Because each KEV entry carries direct evidence of active exploitation, the catalog is one of the highest-signal inputs for risk-based patch management — start here before triaging vulnerabilities that are only theoretically exploitable.
