Known Exploited Vulnerability Catalogs

For the benefit of the cybersecurity community and network defenders—and to help every organization better manage vulnerabilities and keep pace with threat activity—CISA maintains the authoritative source of vulnerabilities that have been exploited in the wild. Organizations should use the KEV catalog as an input to their vulnerability management prioritization framework.

CIRCL provides a known-exploited vulnerability catalog and supports the different status reasons described in GCVE BCP-07.

ENISA, via the CSIRTs network, provides a list of known-exploited vulnerabilities observed across the CSIRTs network.

Vulnerabilities actively exploited in the wild as observed by The Shadowserver Foundation's global honeypot network (honeypot/exploited-vulnerabilities API), ranked by number of unique IPs per day and enriched with CVSS scores and CISA KEV status.

Evidence-backed KEV intelligence enriched with confidence scoring, exploitation status, CISA KEV status, and sensor telemetry.
