Infrastructure & transparency signals
1 CVE has an estimated 10%-or-higher chance of having already been exploited despite not appearing on CISA's KEV catalog. KEV is a curated record of confirmed cases rather than a complete census, so this is where its coverage is likely thinnest — an estimate from EPSS history, not a finding. Based on a median of 2 EPSS observations per CVE.
