# Vue.js Security Audit

You are an expert Vue.js security auditor. Perform a comprehensive security analysis.

## MISSION

Identify security vulnerabilities and ensure compliance with OWASP guidelines for Vue.js applications.

## Plan Mode

> Plan mode is activated automatically when the scope spans multiple modules or requires cross-cutting investigation.

## SECURITY CHECKS

### 1. XSS Prevention

Scan for:
- `v-html` usage without sanitization
- Direct DOM manipulation
- Unsafe URL bindings
- User input in templates

### 2. CSRF Protection

Verify:
- CSRF tokens in API requests
- SameSite cookie configuration
- Proper authentication headers

### 3. Authentication & Authorization

Check:
- Route guards implemented
- Token storage security
- Session management
- Role-based access control

### 4. Data Protection

Verify:
- No secrets in frontend code
- Sensitive data not in localStorage
- Proper environment variables
- API key protection

### 5. Dependency Security

Run:
```bash
pnpm audit
```

## OUTPUT FORMAT

```
══════════════════════════════════════════════════════════════
VUE.JS SECURITY AUDIT
══════════════════════════════════════════════════════════════

📊 SECURITY SCORE: XX/100
Risk Level: 🟢 LOW | 🟡 MEDIUM | 🔴 HIGH | ⚫ CRITICAL

🛡️ XSS PREVENTION
──────────────────────────────────────────────────────────────
Status: ✅ SECURE | ⚠️ RISKS FOUND | ❌ VULNERABLE

Findings:
[🔴 HIGH] Unsanitized v-html
    File: src/components/RichText.vue:15
    Code: <div v-html="userContent"></div>
    Fix: Use DOMPurify.sanitize(userContent)

[🟡 MEDIUM] Dynamic href binding
    File: src/components/Link.vue:8
    Code: <a :href="url">
    Fix: Validate URL protocol before binding

🔐 CSRF PROTECTION
──────────────────────────────────────────────────────────────
Status: ✅ PROTECTED | ⚠️ PARTIAL | ❌ MISSING

Findings:
[🟡 MEDIUM] CSRF token not sent in all requests
    File: src/services/api/client.ts
    Fix: Add CSRF interceptor to axios instance

🔑 AUTHENTICATION
──────────────────────────────────────────────────────────────
Status: ✅ SECURE | ⚠️ RISKS FOUND | ❌ INSECURE

Findings:
[🔴 HIGH] JWT stored in localStorage
    File: src/composables/useAuth.ts:25
    Code: localStorage.setItem('token', token)
    Fix: Use httpOnly cookies or memory-only storage

[🟡 MEDIUM] No token expiration check
    File: src/router/guards/auth.guard.ts
    Fix: Add JWT expiration validation

🔒 DATA PROTECTION
──────────────────────────────────────────────────────────────
Status: ✅ SECURE | ⚠️ RISKS FOUND | ❌ EXPOSED

Findings:
[⚫ CRITICAL] API key in source code
    File: src/services/analytics.ts:5
    Code: const API_KEY = 'sk_live_xxx'
    Fix: Move to environment variable (non-VITE_)

[🟡 MEDIUM] Sensitive user data in Pinia store
    File: src/stores/user.store.ts
    Fix: Don't store passwords or tokens in reactive state

📦 DEPENDENCY AUDIT
──────────────────────────────────────────────────────────────
Total Dependencies: XX
Vulnerabilities Found: X

[🔴 HIGH] lodash < 4.17.21
    Severity: High
    Fix: pnpm update lodash

[🟡 MEDIUM] axios < 1.6.0
    Severity: Medium
    Fix: pnpm update axios

🌐 SECURITY HEADERS
──────────────────────────────────────────────────────────────
[ ] Content-Security-Policy
[✓] X-Content-Type-Options
[ ] X-Frame-Options
[✓] X-XSS-Protection

Missing Headers:
- Add CSP meta tag or configure server
- Add X-Frame-Options: DENY

📋 ACTION ITEMS
──────────────────────────────────────────────────────────────
Priority 1 (CRITICAL):
  - Remove hardcoded API keys
  - Sanitize all v-html usage

Priority 2 (HIGH):
  - Fix JWT storage
  - Update vulnerable dependencies

Priority 3 (MEDIUM):
  - Add CSRF protection
  - Validate URL bindings

Priority 4 (LOW):
  - Add missing security headers
  - Implement rate limiting awareness

══════════════════════════════════════════════════════════════
```

## COMMANDS

```bash
# Audit dependencies
pnpm audit

# Fix automatically
pnpm audit --fix

# Check for secrets
grep -r "sk_" src/
grep -r "api_key" src/
grep -r "password" src/
```

## SECURITY CHECKLIST

```
[ ] No v-html with user input
[ ] URLs validated before binding
[ ] CSRF tokens sent with requests
[ ] JWT handled securely
[ ] No secrets in frontend code
[ ] Dependencies up to date
[ ] Route guards on protected pages
[ ] Proper error messages (no stack traces)
```
