About this Catalog
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.
This Known Exploited Vulnerabilities (KEV) catalog conforms to the GCVE BCP-07 standard (Best Current Practice) standard for documenting vulnerabilities with confirmed or suspected active exploitation.
Each entry includes exploitation status, evidence sources, and characteristics to help organizations prioritize vulnerability remediation efforts.
