How this is computed
Action groups appear first: CISA KEV additions, exploitation evidence, confirmed breaches, and unverified leak-site claims. CVSS and EPSS maintenance follows. Each date is labelled with what it means (published, first seen, disclosed, observed, issued, deadline, or updated). A record is only shown as ended or downgraded when a source says so; a record that simply stops being mentioned is not treated as over.
