Fix Guides
Step-by-step instructions for fixing the most common Laravel security issues. Each guide includes code examples, server configurations, and verification steps.
Critical
- Exposed .env File - Block public access and rotate all compromised credentials
- Debug Mode in Production - Disable APP_DEBUG and stop leaking stack traces
- Telescope Exposed - Gate Telescope behind authentication in production
- Ignition Exposed - Remove or restrict the Ignition debug page
High
- XSS Prevention - Blade {!! !!} risks, output encoding, and CSP headers
- CORS Misconfiguration - Fix wildcard origins and credentials in config/cors.php
- Missing CSRF Protection - Add @csrf tokens and configure VerifyCsrfToken
- Insecure Session Config - Set Secure, HttpOnly, and SameSite cookie flags
- Weak SSL/TLS - Disable old protocols and configure strong cipher suites
- Missing Security Headers - Add HSTS, CSP, X-Frame-Options, and more
- Subdomain Takeover - Audit and clean up dangling DNS records
- Missing Rate Limiting - Protect login and API endpoints from brute force
- SQL Injection Prevention - Use parameterized queries, avoid DB::raw with user input
- JWT Token Vulnerabilities - Secure token signing, expiry, and validation
- Exposed Git Directory - Block access to .git in production
- Exposed Storage Directory - Prevent public browsing of /storage
Medium
- Directory Listing Enabled - Disable Options +Indexes in Apache and Nginx
- Missing Email Security - Configure SPF, DKIM, and DMARC
- DNS Security Issues - Fix dangling records and DNSSEC configuration

Frequently Asked Questions
How do I perform a security audit on a Laravel application?
Start by checking for exposed .env files, verifying security headers (CSP, X-Frame-Options, HSTS), testing CSRF and XSS protections, reviewing file upload handling, checking rate limiting on login and API endpoints, confirming debug mode is off in production, and auditing DNS records for dangling entries. Tools like StackShield automate these checks by scanning your production app externally.
What are the most common Laravel security vulnerabilities?
The most common vulnerabilities are exposed .env files with database credentials and API keys, missing security headers that enable XSS and clickjacking, CSRF token misconfiguration, insecure file upload handling, missing rate limiting on authentication endpoints, debug mode left enabled in production, and DNS misconfigurations that allow subdomain takeover.
Should I run a bug bounty program for my Laravel app?
Yes, even a basic responsible disclosure policy helps. Add a security.txt file at /.well-known/security.txt with contact details. For formal bug bounty programs, platforms like HackerOne and Bugcrowd let you define scope and rewards. Focus bounty scope on authentication, authorization, and data handling endpoints rather than debug or development routes.
How do I check if my Laravel .env file is exposed?
Try accessing yourdomain.com/.env in a browser. If it returns any content, your .env file is publicly accessible and your credentials are compromised. Ensure your web server is configured to block access to dotfiles. In Nginx, add a location block that denies access to files starting with a dot. In Apache, use .htaccess rules to deny access.
