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
- Extract dependencies from project (package.json, etc.)
- Query each source for known CVEs
- Cross-reference findings across sources
- Prioritize by CVSS score and exploitability
- Report with fix versions and workarounds
Query Strategy
For each dependency:
- Search OSV.dev first (fastest, most accurate for packages)
- Cross-check NVD for CVSS scoring
- Use Exa for recent advisories not yet in databases
- 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 |
