Laravel Security Audit: Free Online Scanner for Vulnerabilities and Misconfigurations

Laravel is one of the most secure PHP frameworks available — but only when configured correctly. A default Laravel installation has several security features, yet many developers inadvertently leave debug mode enabled, expose sensitive files, or misconfigure security headers in production.

The Laravel Security Checker by Jayax.dev scans your Laravel application for 15+ common security issues — from exposed environment files to missing CORS configurations.

Why Laravel Security Audits Are Essential

Laravel's Security Strengths (and Weaknesses)

Laravel provides excellent built-in security:

✅ CSRF protection out of the box
✅ SQL injection prevention via Eloquent ORM
✅ XSS protection via Blade templating {{ }} syntax
✅ Password hashing via bcrypt/argon2
✅ Encryption via OpenSSL/AES-256-CBC

But security gaps typically come from:

❌ Misconfigured production environments (APP_DEBUG=true)
❌ Exposed sensitive files (.env, composer.lock, etc.)
❌ Missing security headers (CSP, HSTS, X-Frame-Options)
❌ Improper CORS configuration (allowing all origins)
❌ Outdated dependencies with known CVEs
❌ Weak authentication implementations

Real-World Laravel Vulnerability Statistics

| Vulnerability | % of Laravel Apps Affected | |---------------|---------------------------| | APP_DEBUG enabled in production | ~35% | | Missing security headers | ~60% | | Exposed .env file | ~15% | | Weak CORS policy | ~40% | | Outdated Laravel version | ~45% | | No rate limiting on API | ~50% |

What the Laravel Security Checker Scans

1. Environment & Configuration

APP_DEBUG Status

What it checks: Whether Laravel's debug mode is enabled in production
Why it matters: Debug mode exposes stack traces, environment variables, database credentials, and application code to anyone who triggers an error
How to fix: Set APP_DEBUG=false in your .env file for production. This is the single most critical Laravel security setting.

Environment File Exposure

What it checks: Whether .env is directly accessible via URL
Why it matters: The .env file contains database credentials, API keys, application secrets, and encryption keys
How to fix: Ensure your web server blocks access to dot-files. For Apache, Laravel's default .htaccess handles this. For Nginx, add location ~ /\. { deny all; }

Storage Directory Exposure

What it checks: Whether /storage/ directory is publicly accessible
Why it matters: Contains logs, cached files, session files, and potentially sensitive uploaded content
How to fix: The storage/ directory should be outside the public web root. Configure your web server to only serve files from public/

Maintenance Mode Information Leakage

What it checks: Whether maintenance mode reveals framework information
Why it matters: Attackers can identify your framework and version during downtime
How to fix: Customize the maintenance mode response in resources/views/errors/503.blade.php

2. Security Headers

Content-Security-Policy (CSP)

What it checks: Whether CSP headers are configured
Why it matters: CSP prevents XSS by controlling which resources can be loaded. Without it, inline scripts and external resources can be injected
How to fix: Use spatie/laravel-csp or add headers in middleware

Strict-Transport-Security (HSTS)

What it checks: Whether HSTS header is present
Why it matters: Forces browsers to always use HTTPS, preventing SSL stripping attacks
How to fix: Add Strict-Transport-Security: max-age=31536000; includeSubDomains; preload via middleware

X-Frame-Options

What it checks: Whether clickjacking protection is enabled
Why it matters: Without it, your site can be embedded in an iframe on a malicious site
How to fix: Add X-Frame-Options: DENY or SAMEORIGIN header

X-Content-Type-Options

What it checks: Whether MIME-type sniffing is disabled
Why it matters: Browsers may interpret files as different content types, potentially executing malicious content
How to fix: Add X-Content-Type-Options: nosniff header

Referrer-Policy

What it checks: Whether referrer information is controlled
Why it matters: Sensitive URL parameters (tokens, IDs) may be leaked to third-party sites
How to fix: Add Referrer-Policy: strict-origin-when-cross-origin header

3. CORS & API Security

CORS Configuration

What it checks: Whether Cross-Origin Resource Sharing is properly configured
Why it matters: A wildcard * CORS policy allows any website to make requests to your API
How to fix: Configure config/cors.php to only allow specific trusted origins

API Rate Limiting

What it checks: Whether API routes have rate limiting
Why it matters: Without rate limiting, attackers can brute-force authentication endpoints or overwhelm your API
How to fix: Use Laravel's built-in throttle middleware: Route::middleware('throttle:60,1')

Sanctum/Passport Configuration

What it checks: Whether API authentication is properly set up
Why it matters: Unauthenticated API endpoints expose your data
How to fix: Ensure all sensitive routes have auth middleware

4. File & Directory Security

Sensitive File Access

What it checks: For exposed files like composer.json, package.json, webpack.mix.js, vite.config.js
Why it matters: Reveals your dependencies, scripts, and build configuration
How to fix: These files should not be accessible from the web. Ensure only public/ directory is served

Log File Exposure

What it checks: Whether Laravel logs are accessible via URL
Why it matters: Logs contain stack traces, user information, and potentially sensitive data
How to fix: Ensure storage/logs/ is not publicly accessible

Vendor Directory Exposure

What it checks: Whether the vendor/ directory is accessible
Why it matters: Exposes all PHP dependencies and their versions
How to fix: The vendor/ directory must be outside the web root

5. SSL/TLS Configuration

HTTPS Enforcement

What it checks: Whether the site forces HTTPS
Why it matters: All data (including passwords and session tokens) is transmitted in plaintext over HTTP
How to fix: Set APP_URL=https://... in .env and redirect HTTP to HTTPS

SSL Certificate Validity

What it checks: Whether the SSL certificate is valid and not expired
Why it matters: Expired or invalid certificates break trust and allow MITM attacks
How to fix: Renew your SSL certificate. Use Let's Encrypt for free certificates

FAQ — Laravel Security Checker

Is this tool safe for production environments?

Yes. The scanner performs non-invasive, read-only checks. It only accesses publicly available information and never attempts to exploit vulnerabilities, modify files, or inject code.

Can it detect all Laravel vulnerabilities?

No tool can detect all vulnerabilities. Our scanner focuses on configuration and hardening issues that are most commonly exploited. For comprehensive testing, combine with:

Static analysis tools (PHPStan, Psalm)
Dependency scanning (composer audit)
Professional penetration testing

How is this different from `composer audit`?

composer audit checks your PHP dependencies for known CVEs. Our tool checks your application configuration and web server setup. They complement each other — use both for complete coverage.

Does it work with Laravel Vapor / serverless?

Yes, the scanner works with any publicly accessible Laravel application, including those hosted on Laravel Vapor, Laravel Forge, Heroku, AWS, or any other hosting platform.

What Laravel versions are supported?

The scanner works with Laravel 6.x through 11.x. Some checks may not apply to very old versions.
