Automated CVE Triaging with Composite Risk Scores

Description and use

Automated CVE triage that aggregates NVD, EPSS, and CISA KEV data to compute composite risk scores and prioritize remediation actions.

Problem

Manual CVE triage is time‑consuming and error‑prone, making it hard to prioritize vulnerabilities quickly.

Outcome

The system significantly speeds up CVE triage, providing a clear, data‑driven prioritization that helps teams focus on the most critical vulnerabilities first.

Workflow

• 1. Trigger triage job for a set of CVEs.
• 2. Parallelly query NVD, EPSS, and CISA KEV APIs for each CVE.
• 3. Aggregate data and calculate a composite risk score per CVE.
• 4. Rank CVEs by score and generate a prioritized recommendation list.
• 5. Deliver results to security analysts via a dashboard or notification.

Evidence

Automates CVE triaging by querying NVD, EPSS, and CISA KEV in parallel to calculate composite risk scores and deliver prioritized recommendations.
