CVE Intelligence

CVE Intelligence is HarborGuard's built-in vulnerability database, aggregated from four authoritative sources and cross-referenced against the packages currently deployed across your scanned images.

Sources

SourceWhat it provides
NVD (NIST National Vulnerability Database)Authoritative CVE records with CVSS v3.1 / v4 scoring, CPE matches, and CWE mappings.
OSV (Open Source Vulnerabilities)Ecosystem-aware advisories from Google for npm, PyPI, Go, RubyGems, crates.io, and others.
GHSA (GitHub Security Advisories)Curated advisories with proposed fix versions and reviewed exploitability notes.
CISA KEV (Known Exploited Vulnerabilities)The U.S. CISA catalogue of CVEs with confirmed exploitation in the wild.

Cross-referencing and deduplication

When the same vulnerability appears in multiple sources (NVD assigns a CVE, GHSA publishes an advisory, OSV imports the GHSA), HarborGuard stitches them into a single intelligence record keyed by CVE ID. Source-specific identifiers (GHSA-xxxx, OSV-xxxx) are kept on the record so you can trace any field back to its origin.

For each record, HarborGuard computes:

  • The affected packages across all sources, normalised to PURL form.
  • The canonical CVSS score — preferring NVD, falling back to GHSA when NVD has not scored the CVE yet.
  • The KEV flag — set when CISA has added the CVE to the Known Exploited Vulnerabilities catalogue.
  • The org impact — the count of your scanned images currently affected, computed by joining the affected-package set against your dependency inventory.
