<objective>
This skill researches known vulnerabilities for a specific dependency across multiple
sources: OSV.dev (npm, PyPI, Go, crates, Maven), NVD (CVSS scoring), GitHub Advisory
Database (maintainer responses), and Exa web search for advisories not yet indexed.

It queries OSV.dev first for speed and accuracy, cross-checks NVD for CVSS scoring, uses Exa
for recent advisories, and checks GitHub Advisory for maintainer responses, then
cross-references findings and prioritizes by CVSS score and exploitability — CRITICAL
(9.0-10.0) fixed immediately, HIGH (7.0-8.9) before merge, MEDIUM (4.0-6.9) planned, LOW
(0.1-3.9) documented — reporting fix versions and workarounds.

Out of scope: this is a single-dependency lookup, not a full project dependency sweep (use
dependency-audit for that).

# CVE Research Skill

## Overview

Research known vulnerabilities for project dependencies using multiple sources.

## Data Sources

| Source | API | Coverage |
|--------|-----|----------|
| NVD | nvd.nist.gov/vuln/api | All CVEs |
| OSV.dev | api.osv.dev | npm, PyPI, Go, crates, Maven |
| GitHub Advisory | github.com/advisories | npm, pip, composer, cargo |
| Exa Search | Via MCP | Real-time web search |

## Workflow

1. **Extract** dependencies from project (package.json, etc.)
2. **Query** each source for known CVEs
3. **Cross-reference** findings across sources
4. **Prioritize** by CVSS score and exploitability
5. **Report** with fix versions and workarounds

## Query Strategy

For each dependency:
1. Search OSV.dev first (fastest, most accurate for packages)
2. Cross-check NVD for CVSS scoring
3. Use Exa for recent advisories not yet in databases
4. Check GitHub Advisory for maintainer responses

## Severity Mapping

| CVSS Score | Severity | Action |
|------------|----------|--------|
| 9.0 - 10.0 | CRITICAL | Fix immediately |
| 7.0 - 8.9 | HIGH | Fix before merge |
| 4.0 - 6.9 | MEDIUM | Plan fix |
| 0.1 - 3.9 | LOW | Document |
