Automate OWASP Security Audits with Claude Code Security Pack

#claudecode #security #owasp #devops

Security reviews are one of the most time-consuming parts of the development cycle. Checking against OWASP Top 10, hunting for hardcoded secrets, and cross-referencing dependency CVEs — these are all critical, but they eat hours of developer time that could go toward shipping features.

The Claude Code Security Pack automates all three with three purpose-built skills: /security-audit, /secret-scanner, and /deps-check.

Why OWASP Top 10 Still Catches Teams Off Guard

The OWASP Top 10 has been the industry standard for web application security risks since 2003. Yet injection flaws, broken authentication, and security misconfigurations still appear regularly in production codebases — not because developers don't know about them, but because manual auditing is slow and easy to skip under deadline pressure.

Automated tooling changes this dynamic. When the check runs in seconds, it gets done every time.

How /security-audit Works

Point it at your source directory:

/security-audit src/
Enter fullscreen mode Exit fullscreen mode

The skill analyzes your code against OWASP Top 10 categories and outputs prioritized findings:

[CRITICAL] A03: Injection
  src/api/orders.py:87 — Raw SQL query with unsanitized user input
  Fix: Use parameterized queries or an ORM

  # Flagged code:
  query = f"SELECT * FROM orders WHERE user_id = {user_id}"

  # Suggested fix:
  cursor.execute("SELECT * FROM orders WHERE user_id = %s", (user_id,))

[HIGH] A02: Cryptographic Failures
  src/auth/tokens.py:23 — JWT signed with HS256 using a hardcoded secret
  Fix: Load signing key from environment; consider RS256 for distributed systems

[MEDIUM] A05: Security Misconfiguration
  config/app.py:11 — CORS origin set to "*" with credentials allowed
  Fix: Specify allowed origins explicitly
Enter fullscreen mode Exit fullscreen mode

Each finding includes the file path, line number, OWASP category, and a concrete remediation suggestion. No need to cross-reference documentation — the guidance is inline.

/secret-scanner: Catch Leaked Credentials Before They Hit Git

Hardcoded secrets in source code are a leading cause of breaches. This skill scans your entire project tree for patterns matching API keys, tokens, and passwords:

/secret-scanner .
Enter fullscreen mode Exit fullscreen mode

Example detections:

# These patterns get flagged:
STRIPE_SECRET_KEY = "sk_live_4eC39HqLyjWDarjtT1zdp7dc"
POSTGRES_URI = "postgresql://admin:hunter2@prod.db.internal/app"
AWS_SECRET_ACCESS_KEY = "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
Enter fullscreen mode Exit fullscreen mode 
[FOUND] src/config/settings.py:14
  Type: Stripe Live Secret Key
  Match: sk_live_4eC39... (truncated)
  Action: Rotate immediately. Move to environment variable or secrets manager.

[FOUND] docker-compose.yml:31
  Type: Database URI with credentials
  Note: docker-compose files are often committed to version control — verify .gitignore
Enter fullscreen mode Exit fullscreen mode

Running this as a pre-commit hook or CI step eliminates an entire class of credential exposure incidents.

/deps-check: Vulnerability Scanning for Your Dependencies

Supply chain attacks and unpatched dependencies are a growing attack vector. /deps-check scans your dependency manifest against known CVEs:

/deps-check requirements.txt
# or
/deps-check package.json
Enter fullscreen mode Exit fullscreen mode

Sample output:

Scanning 63 packages...

[HIGH] CVE-2024-3094 — cryptography==41.0.0
  CVSS: 9.1 — Allows remote code execution via malformed certificate
  Fix: pip install "cryptography>=42.0.4"

[HIGH] CVE-2023-32681 — requests==2.28.1
  CVSS: 7.5 — Authentication headers leaked on cross-origin redirects
  Fix: pip install "requests>=2.31.0"

[MEDIUM] CVE-2023-45853 — Pillow==9.5.0
  CVSS: 5.3 — Buffer overflow in TIFF parsing
  Fix: pip install "Pillow>=10.0.1"

Summary: 2 HIGH, 1 MEDIUM, 0 LOW
Upgrade command: pip install --upgrade cryptography requests Pillow
Enter fullscreen mode Exit fullscreen mode

The upgrade command is generated automatically, so remediation is a single copy-paste.

Getting Started in 3 Steps

Step 1: Install the Security Pack skills

Download from PromptWorks and place the skill files in your Claude Code skills directory (~/.claude/skills/ or the project-local .claude/skills/).

Step 2: Run your first audit

# In your project root
/secret-scanner .
/deps-check requirements.txt   # or package.json / Gemfile.lock
/security-audit src/
Enter fullscreen mode Exit fullscreen mode

Step 3: Integrate into CI

# .github/workflows/security-pack.yml
name: Security Pack Audit

on:
  pull_request:
    branches: [main, develop]

jobs:
  security:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Secret Scanner
        run: claude /secret-scanner .
      - name: Dependency Check
        run: claude /deps-check requirements.txt
      - name: OWASP Audit
        run: claude /security-audit src/
Enter fullscreen mode Exit fullscreen mode

Now every pull request gets an automated security review before merge.
