Security Vulnerability Check Skill

📋 Overview

Check project dependencies for known security vulnerabilities, supporting multiple languages and package managers:

• 🔒 CVE Database: Detect known vulnerabilities
• 📊 Severity Scoring: CVSS scoring system
• 🔧 Fix Recommendations: Suggest secure versions
• 🚨 Real-time Updates: Latest vulnerability data

🔧 Prerequisites

Language/Tool	Check Tool	Installation
Python	pip-audit, Safety	pip install pip-audit safety
JavaScript	npm audit	Built into npm
Java	OWASP Dependency-Check	Download CLI
.NET	dotnet list package --vulnerable	Built into .NET SDK
Ruby	bundler-audit	gem install bundler-audit
Go	govulncheck	go install golang.org/x/vuln/cmd/govulncheck@latest

🚀 Usage

Method 1: Use AI Assistant

"Check project security vulnerabilities"
"Scan dependencies for CVEs"
"Run security audit"

Method 2: Run Commands Manually

Python:

# Using pip-audit (recommended)
pip-audit                           # Scan current environment
pip-audit -r requirements.txt       # Scan specific file

# Using Safety
safety check                        # Scan current environment
safety check --json                 # JSON output

JavaScript/Node.js:

npm audit                           # Scan and show vulnerabilities
npm audit fix                       # Auto-fix (minor versions)
npm audit fix --force               # Force fix (may break compatibility)
npm audit --json                    # JSON output

Yarn:

yarn audit                          # Scan vulnerabilities
yarn audit --level high             # Show high severity only

pnpm:

pnpm audit                          # Scan vulnerabilities
pnpm audit --fix                    # Auto-fix

Java (Maven):

# Using OWASP Dependency-Check
mvn org.owasp:dependency-check-maven:check

# Using Snyk
snyk test

.NET:

dotnet list package --vulnerable              # List vulnerabilities
dotnet list package --vulnerable --include-transitive  # Include transitive deps

Ruby:

bundle audit check                  # Check Gemfile.lock
bundle audit update                 # Update vulnerability database

Go:

govulncheck ./...                   # Scan all packages
govulncheck -json ./...             # JSON output

🎯 What It Checks

Vulnerability Detection

• ✅ Known CVE IDs
• ✅ CVSS scores (severity)
• ✅ Affected version ranges
• ✅ Vulnerability descriptions and links

Dependency Analysis

• ✅ Direct dependencies
• ✅ Transitive dependencies
• ✅ Development dependencies (optional)
• ✅ License checks (some tools)

Fix Recommendations

• ✅ Recommended secure versions
• ✅ Fix PRs (some tools)
• ✅ Workarounds (if upgrade not possible)
• ✅ Alternative package recommendations

🆘 FAQ

Q: What to do after finding vulnerabilities?
A:

1. Assess severity (CVSS score)
2. Check if it affects your use case
3. Upgrade to fixed version
4. If upgrade not possible, find alternatives or mitigations

Q: What if npm audit fix breaks compatibility?
A:

1. First run npm audit to see details
2. Manually upgrade specific packages: npm update package-name
3. Use npm audit fix --dry-run to preview
4. Test before committing

Q: How to ignore specific vulnerabilities?
A:

• npm: Use npm audit fix --force or .auditrc
• Python: Add exceptions in .safety-policy.yml
• Note: Must have valid reason and review regularly

Q: CI/CD security check failures causing build failures?
A:

1. Set severity threshold (e.g., only high/critical fail)
2. Use continue-on-error: true as warning
3. Fix vulnerabilities regularly, don't accumulate

Q: How to prevent introducing vulnerabilities?
A:

1. Pre-commit hook running security checks
2. Auto-run audit in PRs
3. Use tools like Snyk/Dependabot for auto PRs
4. Regularly update dependencies
