Claude Code Agent: Security Auditor — OWASP & Dependency Scan

Claude Code agent that audits your codebase for OWASP top 10 vulnerabilities, dependency issues, and security anti-patterns.

TL;DR
A Claude Code agent that scans your codebase for OWASP top 10 issues, CVEs, leaked secrets, and security anti-patterns.
§01

What it is

This is a security-focused Claude Code agent that audits your codebase for vulnerabilities. It checks for OWASP top 10 issues, scans dependencies for known CVEs, detects leaked secrets, and verifies compliance with security best practices. The agent is part of the Claude Code Templates collection.

It is designed for developers, security engineers, and DevOps teams who want automated security reviews before deployments or on a regular schedule. The agent uses Claude Code's file exploration tools to scan source code, configuration files, and dependency manifests.

§02

How it saves time or tokens

Manual security audits require expertise across multiple domains: injection attacks, authentication flaws, cryptographic misuse, and dependency management. This agent consolidates those checks into a single automated pass.

Running the agent before each deployment catches issues early, when they are cheap to fix. A SQL injection found during code review costs minutes to fix. The same vulnerability found in production costs incident response time, potential data exposure, and customer trust.

§03

How to use

  1. Install the security auditor agent:
npx claude-code-templates@latest --agent security/security-auditor --yes
  1. The agent activates automatically when Claude Code detects security-related tasks. You can also invoke it directly by asking for a security audit.
  1. Point it at specific directories or ask for a full codebase scan:
Run a security audit on the src/api/ directory.
Focus on authentication and input validation.
§04

Example

Asking the agent to check for common vulnerabilities:

Audit this Express.js API for OWASP top 10 issues.
Check package.json dependencies for known CVEs.
Look for hardcoded secrets in .env files and config/.

The agent produces a structured report:

§05

Security Audit Results

Critical

  • SQL injection in src/api/users.js:42 - raw user input in query
  • Hardcoded API key in config/payment.js:15

High

  • express-session using default cookie settings (no secure flag)
  • jsonwebtoken@8.5.1 has known CVE-2022-23529

Medium

  • CORS configured with wildcard origin
  • No rate limiting on /api/auth/login endpoint

Common pitfalls

  • The agent checks source code patterns but does not run dynamic analysis. It cannot detect runtime vulnerabilities like SSRF that depend on network configuration.
  • Dependency scanning relies on manifest files (package.json, requirements.txt, go.mod). If dependencies are vendored without manifests, the agent may miss them.
  • False positives are possible. The agent flags patterns that look like vulnerabilities but may be intentional (e.g., a test file with a hardcoded token for unit tests). Review findings before acting.

Frequently Asked Questions

What OWASP categories does the agent check?+

The agent checks for all OWASP top 10 categories including injection, broken authentication, sensitive data exposure, XML external entities, broken access control, security misconfiguration, cross-site scripting, insecure deserialization, using components with known vulnerabilities, and insufficient logging.

Does it scan dependencies for CVEs?+

Yes. The agent reads dependency manifests (package.json, requirements.txt, go.mod, Cargo.toml) and checks for packages with known CVEs. It flags the specific vulnerability and suggests the minimum version that includes the fix.

Can it detect leaked secrets?+

Yes. The agent scans for patterns that match API keys, database credentials, JWT secrets, and other sensitive values in source code and configuration files. It checks both hardcoded values and environment variable misuse.

How often should I run the security auditor?+

Run it before each deployment and after adding new dependencies. For high-security applications, schedule it as part of your CI pipeline. The agent is designed for repeated runs, producing consistent reports that can be diffed over time.

Does it replace tools like Snyk or Dependabot?+

It complements them. Snyk and Dependabot focus on dependency vulnerabilities with CVE databases. This agent adds source code analysis for OWASP issues, secret detection, and security anti-patterns that dependency scanners do not cover.
