Domain knowledge for EPSS — exploit probability scores for CVEs, risk prioritization

EPSS

The Exploit Prediction Scoring System (EPSS) by FIRST.org estimates the probability a CVE will be exploited within 30 days. Prioritize remediation by exploit likelihood.

Data Model

  • Score lookup: epss_score_lookup, epss_score_history, epss_score_at_date.
  • Most exploitable: epss_most_exploitable(min_score), epss_score_by_percentile.
  • Triage, Search: epss_triage(cve_ids), epss_search(query, min_score).
  • Risk report: epss_risk_report.

Gotchas

  • Free public API: Rate limit 60/min. Use batch lookups, cache results.
