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.

Catalog overlap How much each pair of KEV catalogs shares. Each cell is the number of vulnerabilities present in both catalogs; colour intensity is the Jaccard index (shared ÷ combined). The diagonal shows each catalog's own total.

Hover a cell to compare two catalogs.

Coverage timeline Cumulative number of vulnerabilities each catalog has listed over time, by each catalog's earliest observation date (first seen, then recorded, falling back to the status update). A steep step marks a bulk import.

Hover a line for a catalog's running total.

Coverage lead time Which catalog tends to list a vulnerability first. Based on each catalog's earliest observation date (first seen, then recorded, falling back to the status update).

2302

Across 2302 vulnerabilities listed by more than one catalog, half reach all of their catalogs within 2 days of the first listing. The bars show how often each catalog is the earliest to list a vulnerability it shares.

Overlapping catalogs list 49% of shared vulnerabilities on the same day (often because one catalog mirrors another's listing date), so the per-catalog lead below is typically near zero — it is an average, surfacing the genuine separation in the long tail.

Hover a catalog for its lead-time detail.

Blind spots Vulnerabilities other catalogs flag as exploited but a given catalog does not carry. Click a catalog to list its gaps in the coverage table below; the corroborated figure counts those confirmed by two or more other catalogs — the stronger signal worth investigating.

Catalog combinations An UpSet view of catalog membership: each bar counts the vulnerabilities present in exactly the catalogs marked below it. The left bars show each catalog's own total — a catalog's columns are disjoint slices that add up to that total. Click a column to filter the coverage table below to that combination.

2968

Hover a column to see which catalogs share that group of vulnerabilities.

Catalog coverage Vulnerabilities other catalogs flag as exploited but Shadowserver does not carry — its blind spots, newest first listed at the top.
