5 Security Issues Documented
Common vulnerabilities found in Railway applications
Critical Security Issues
Public Database Endpoint
criticalDatabase accessible from public internet.
Database exposed to credential attacks.
Check if using public vs private database URL.
Enable Private Networking. Use internal database URL.
High Severity Issues
Connection String in Logs
highDatabase credentials visible in application logs.
Anyone with log access sees database credentials.
Search logs for connection strings or passwords.
Remove console.log of env vars. Use structured logging.
Auto-Deploy Without Review
highPush triggers production deploy without approval.
Vulnerable code reaches production immediately.
Check deploy configuration for auto-deploy status.
Enable branch protection. Require PR reviews.
Missing API Authentication
highRailway-deployed APIs without auth checks.
Unauthorized access to API endpoints.
Call API endpoints without credentials.
Add authentication middleware to all protected routes.
Medium Severity Issues
Resource Limits Not Set
mediumNo memory or CPU limits on services.
Runaway costs from DoS or bugs.
Check service configuration for resource limits.
Configure appropriate memory and CPU limits.
How to Prevent These Issues
- Run automated security scans before every deployment
- Configure database access controls (RLS/Security Rules) first
- Store all secrets in environment variables, never in code
- Enable email verification and strong password policies
- Add security headers to your hosting configuration
- Review AI-generated code for security before accepting

Get Starter ScanFrequently Asked Questions
What are the most common Railway security issues?
The most common issues are: exposed API keys/secrets, missing database access controls (RLS or Security Rules), weak authentication configuration, and missing security headers. These account for over 80% of vulnerabilities in Railway applications.
How do I find security issues in my Railway app?
Run a VAS security scan for automated detection of common vulnerabilities. Manually check: database access controls, search code for hardcoded secrets, verify authentication settings, and test security headers. VAS catches all of these automatically.
Are Railway security issues fixable?
Yes, nearly all Railway security issues are configuration problems with straightforward fixes. Missing RLS, exposed secrets, weak auth—all have clear remediation steps. Most fixes take under an hour to implement.
How quickly can Railway security issues be exploited?
Exposed databases and API keys can be discovered within minutes using automated scanners. Attackers actively scan for common patterns. This is why security configuration must happen before deployment, not after.
Does Railway have built-in security?
Railway provides security features, but they require configuration. Security isn't automatic—you must enable database access controls, manage secrets properly, configure auth settings, and add security headers. The tools exist; you must use them.
