About This Vulnerability Database

This vulnerability database is built from three public data sources: the official CVE List for record data, the CISA KEV catalog for confirmed exploitation, and FIRST EPSS for exploitation probability. Records update on a daily sync.

Each record shows the CVSS base score from the assigning CNA or CISA, the EPSS percentile, affected vendor and product versions, and references grouped by type. KEV entries additionally carry the federal remediation due date and the required action CISA publishes.

Frequently Asked Questions

What is a vulnerability database?→

A vulnerability database collects records of publicly disclosed security flaws, identified by CVE IDs, with severity scores, affected products, and references. This database focuses on exploited and high-probability CVEs rather than every published record.

What is the CISA Known Exploited Vulnerabilities catalog?→

The CISA KEV catalog lists CVEs confirmed as exploited in the wild. US federal agencies must remediate listed vulnerabilities by a set due date, and the catalog is widely used as a remediation priority signal outside government.

What is an EPSS score?→

EPSS (Exploit Prediction Scoring System) is a FIRST-maintained model that estimates the probability a CVE will be exploited in the next 30 days. Scores range from 0 to 1 and update daily as new threat data arrives.

Which vulnerabilities are included in this database?→
  • +Every CVE listed in the CISA KEV catalog, regardless of publication year.
  • +CVEs with a 2026-or-later ID and an EPSS score of 0.1 or higher.
  • +CVEs with a 2026-or-later ID, an exploit-tagged reference, and an EPSS score of 0.05 or higher.
How often is this vulnerability database updated?→

Records sync daily from the CVE List, the CISA KEV catalog, and FIRST EPSS. New KEV additions and EPSS score changes appear on the next sync.
