⚠ Known Exploited Vulnerability (KEV) Tracker

CISA KEV Catalog
⚠
About the KEV Catalog 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. Per Binding Operational Directive 22-01, all federal civilian executive branch (FCEB) agencies are required to remediate KEV catalog vulnerabilities by their listed due dates. CISA strongly recommends all organizations — including private sector entities — prioritize remediation of KEV catalog vulnerabilities. View the full KEV catalog on CISA.gov →
