mcp_context7_query-docs(libraryId="/laravel/docs", query="authentication security")
```

### 🌐 Web Search — CVE and Vulnerability Lookup
```

```

## Validation Loop (MANDATORY)

Every security review MUST run these dependency checks:
```bash
composer audit            # Check PHP vulnerabilities
npm audit                 # Check JS vulnerabilities
php artisan route:list --compact  # Verify route middleware
```

Report any vulnerabilities found as Critical findings.

## Instructions

1. Run `git diff` to identify changed files
2. Scan for security vulnerabilities using checklist below
3. Check authentication and authorization patterns
4. Review input validation and sanitization
5. Report findings by severity (Critical → Warning → Suggestion)

## OWASP Top 10 Checklist

| # | Vulnerability | Laravel Check | React Check |
|---|---------------|---------------|-------------|
| A01 | Broken Access Control | Policies, Gates | Route guards |
| A02 | Cryptographic Failures | `Hash::make`, `encrypt` | No secrets in client |
| A03 | Injection | Eloquent, query builder | No `dangerouslySetInnerHTML` |
| A04 | Insecure Design | Business logic review | Component security |
| A05 | Security Misconfiguration | `.env` settings | Build config |
| A06 | Vulnerable Components | `composer audit` | `npm audit` |
| A07 | Auth Failures | Rate limiting, sessions | Token handling |
| A08 | Data Integrity | CSRF, mass assignment | Form validation |
| A09 | Logging Failures | Security event logs | Error boundaries |
| A10 | SSRF | URL validation | API call validation |

## Laravel Security Checks

```php
// Mass Assignment
$fillable = ['name', 'email'];  // ✅ Whitelist
$guarded = ['id', 'is_admin'];  // ✅ Blacklist

// SQL Injection Prevention
User::where('email', $email)->first();  // ✅ Safe
DB::raw("SELECT * FROM users WHERE email = '$email'");  // ❌ Dangerous

// CSRF
@csrf  // ✅ In forms
```

## React Security Checks

```tsx
// XSS Prevention
<div>{userInput}</div>  // ✅ Auto-escaped
<div dangerouslySetInnerHTML={{__html: userInput}} />  // ❌ XSS risk

// No secrets in client
const API_KEY = process.env.NEXT_PUBLIC_API_KEY;  // ⚠️ Visible to users
```

## Audit Commands

```bash
composer audit          # PHP vulnerabilities
npm audit               # JS vulnerabilities
php artisan route:list  # Check route middleware
```
