## What it does

The skill runs audits across seven steps. First, the model searches for committed credentials, AWS or Stripe tokens, and unignored `.env` files. It then examines authentication logic, password hashing algorithms, and injection risks like raw SQL queries, template rendering, and `child_process.exec()` calls.

The review also inspects dependencies using `npm audit` or `pip audit`, checks CORS and CSP headers, and looks for sensitive fields leaking in API responses or logs. Findings are compiled into a report grouped by Critical, High, Medium, and Low severity, complete with file paths, line numbers, and fixes.

This is a code review, not a penetration test. Finding live deployment vulnerabilities requires tools like `trivy` or `snyk`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill auditing-security -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/auditing-security/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/auditing-security/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill auditing-security -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/auditing-security/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill auditing-security -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/auditing-security/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install spencerpauly/awesome-cursor-skills auditing-security
```

2. **Manually: put the files in place**
- File: `.github/skills/auditing-security/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill auditing-security -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/spencerpauly/awesome-cursor-skills --path resources/auditing-security
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/auditing-security/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill auditing-security -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/spencerpauly/awesome-cursor-skills/tree/HEAD/resources/auditing-security/SKILL.md

## When to use it
- Scan files for committed API keys, tokens, and credentials
- Detect SQL injections, XSS sinks, and command execution flaws
- Verify CORS headers, CSP policies, and session cookie flags
- Generate a vulnerability report with file paths and severity ratings

## Example prompts
- Audit the security of this codebase and check for OWASP vulnerabilities
- Review our authentication and authorization logic for security flaws
- Perform a security audit and produce a report with severity ratings

# Security Audit

Use this skill when the user asks to audit security, check for vulnerabilities, review code for security issues, or harden an application.

## Steps

1. **Scan for hardcoded secrets** — search for API keys, tokens, passwords, and connection strings in source files. Check for patterns like:
   - `password=`, `secret=`, `token=`, `api_key=`
   - Base64-encoded credentials
   - AWS keys (`AKIA...`), Stripe keys (`sk_live_...`), GitHub tokens (`ghp_...`)
   - Files: `.env` committed to git, `config.json` with credentials

2. **Check authentication & authorization**
   - Verify all API routes check authentication before processing.
   - Ensure role-based access control is enforced server-side, not just in the UI.
   - Check that password hashing uses bcrypt/argon2 (not MD5/SHA1).
   - Verify session tokens are HTTP-only, secure, and have reasonable expiry.

3. **Check for injection vulnerabilities**
   - **SQL injection**: look for string concatenation in SQL queries instead of parameterized queries.
   - **XSS**: look for `dangerouslySetInnerHTML`, `innerHTML`, or unescaped user input rendered in templates.
   - **Command injection**: look for `exec()`, `eval()`, `child_process.exec()` with user input.
   - **Path traversal**: check file operations for unsanitized user input in paths.

4. **Review dependency security**
   - Run `npm audit` or `pip audit` to check for known vulnerabilities.
   - Flag outdated dependencies with known CVEs.
   - Check for overly permissive dependency ranges.

5. **Check CORS and CSP configuration**
   - Verify CORS doesn't use `Access-Control-Allow-Origin: *` in production.
   - Check for Content Security Policy headers.
   - Verify `X-Frame-Options`, `X-Content-Type-Options`, and `Strict-Transport-Security` headers.

6. **Review data exposure**
   - Check API responses for leaking sensitive fields (password hashes, internal IDs, PII).
   - Verify error messages don't expose stack traces or internal details in production.
   - Check logging for sensitive data being written to logs.

7. **Generate report** — produce a summary with severity ratings (Critical / High / Medium / Low) for each finding, with the file path, line number, and recommended fix.

## Notes

- This is a code review, not a penetration test. Recommend tools like `npm audit`, `trivy`, or `snyk` for automated scanning.
- Always check `.gitignore` to ensure `.env`, credentials, and key files are excluded.
- For comprehensive auditing, recommend the OWASP Testing Guide.
