Dependency Audit

Quick Start

Audit dependencies based on project type:

# Node.js
npm audit

# Python
pip-audit

# Go
govulncheck ./...

Instructions

Step 1: Identify Package Manager

Check for manifest files:

• package.json / package-lock.json → npm/yarn
• requirements.txt / pyproject.toml → pip
• go.mod → Go modules
• Cargo.toml → Cargo (Rust)
• Gemfile → Bundler (Ruby)

Step 2: Run Audit

Node.js (npm):

npm audit
npm audit --json  # Machine-readable output

Node.js (yarn):

yarn audit
yarn audit --json

Python:

pip install pip-audit
pip-audit
pip-audit -r requirements.txt

Go:

govulncheck ./...

Ruby:

bundle audit check --update

Step 3: Analyze Results

Categorize by severity:

Step 4: Fix Vulnerabilities

npm - Auto-fix:

npm audit fix
npm audit fix --force  # Breaking changes allowed

npm - Manual update:

npm update vulnerable-package
# or specific version
npm install vulnerable-package@2.0.0

Python - Update package:

pip install --upgrade vulnerable-package
# or pin safe version in requirements.txt
vulnerable-package>=2.0.0

Step 5: Verify Fixes

Re-run audit to confirm:

npm audit  # Should show 0 vulnerabilities
pip-audit  # Should show no issues

Common Scenarios

Transitive Dependencies

When vulnerability is in a sub-dependency:

# Check dependency tree
npm ls vulnerable-package

# Force resolution (npm)
# Add to package.json:
{
  "overrides": {
    "vulnerable-package": "2.0.0"
  }
}

No Fix Available

When no patched version exists:

1. Check if vulnerability affects your usage
2. Consider alternative packages
3. Implement workarounds if possible
4. Monitor for updates

Breaking Changes

When fix requires major version bump:

1. Review changelog for breaking changes
2. Update code to accommodate changes
3. Run tests thoroughly
4. Consider gradual rollout
