name: cve-watchlist-action-recommendation-generator description: Generate prioritized CVE watchlists and actionable security recommendations for repositories. Use when analyzing CVE scan results, creating security reports, prioritizing vulnerability remediation, or generating security gate reports for CI/CD. Takes CVE scan results (JSON/SARIF from npm audit, pip-audit, Snyk), reachability analysis, and cutoff date as input. Combines severity, reachability, exploitability, and dependency criticality to rank CVEs by practical risk. Outputs markdown reports with concrete next-step guidance (immediate upgrade, monitor, ignore with justification, apply mitigation) suitable for issue trackers, security reviews, and CI security gates.

CVE Watchlist & Action Recommendation Generator

Generate prioritized CVE watchlists with actionable security recommendations for development and security teams.

Workflow

1. Gather Input Data

Collect required inputs:

Required:

• Repository name/path
• CVE scan results (JSON/SARIF format from npm audit, pip-audit, Snyk, etc.)
• Cutoff date (YYYY-MM-DD) for filtering new CVEs

Optional but recommended:

• Reachability analysis results (which vulnerable code paths are actually used)
• Exploit intelligence data (CISA KEV, ExploitDB)
• Dependency criticality ratings (how critical each dependency is)

Parse scan results:

python scripts/parse_scan_results.py scan_results.json auto 2024-01-01 > parsed_cves.json

2. Calculate Risk Scores

Combine multiple risk factors to prioritize CVEs:

python scripts/calculate_risk_score.py parsed_cves.json reachability.json exploits.json criticality.json > scored_cves.json

Risk scoring formula:

Risk Score = (Severity × 0.35) + (Reachability × 0.30) + (Exploitability × 0.20) + (Dependency Criticality × 0.15)

See risk_scoring.md for detailed methodology.

3. Generate Recommendations

For each CVE, determine appropriate action based on risk score and context:

Decision tree:

• Risk ≥ 80 (Critical) → Immediate upgrade (24-48h)
• Risk 60-79 (High) → Upgrade within days (3-5 days)
• Risk 40-59 (Medium) → Next maintenance cycle (2-4 weeks)
• Risk 20-39 (Low) → Monitor or defer
• Risk < 20 (Minimal) → Ignore with justification

See action_guidelines.md for complete decision tree and recommendation templates.

4. Generate Report

Create markdown-formatted report using template:

Report structure:

1. Executive Summary (CVE counts by risk tier)
2. Prioritized CVE Watchlist (grouped by risk tier)
3. For each CVE:
   • Risk score and breakdown
   • Affected package and versions
   • Reachability status
   • Exploit availability
   • Concrete action recommendation
   • Upgrade commands
   • Mitigation options (if applicable)
4. Summary of Actions (immediate, short-term, medium-term)
5. Dependency Overview
6. Next Steps

Use template from assets/report_template.md.

### 🔴 Critical Risk

#### CVE-2024-1234: SQL Injection in database-driver

**Risk Score**: 96 / 100 (Critical)

**Affected Package**: database-driver@1.2.3

**Severity**: Critical (CVSS 9.8)

**Reachability**: Direct call from src/db/query.js:42

**Exploitability**: Public exploit available (ExploitDB)

**Action**: Immediate upgrade required

**Steps**:
1. Upgrade database-driver from 1.2.3 to 2.0.0
2. Run full test suite
3. Deploy with rollback plan

**Command**:
```bash
npm install database-driver@2.0.0

Risk if not addressed: Attackers can execute arbitrary SQL queries, leading to data breach

## Tips

- **Always include reachability data** when available - it significantly improves prioritization accuracy
- **Check for breaking changes** in fix versions before recommending immediate upgrades
- **Document assumptions** when data is missing (e.g., "Assuming moderate risk due to unknown reachability")
- **Provide specific commands** for each package manager (npm, pip, maven, etc.)
- **Include mitigation options** for high-risk CVEs when upgrades are blocked
- **Link to CVE details** and security advisories for further investigation
- **Group multiple CVEs** in the same package when a single upgrade fixes all
