4 Security Issues Documented
Common vulnerabilities found in Xano applications
High Severity Issues
Unauthenticated API Endpoints
highAPI groups published without auth middleware allow anyone to read, create, or delete data.
Account takeover of legitimate users. Attackers gain full access to victim accounts and any data/actions those accounts permit.
Attempt 20+ login requests with the same username in under 60 seconds. If all complete without rate limiting or lockout, the issue is present.
Enforce email verification, minimum password requirements, and rate limiting on auth endpoints. Test auth flows as unauthenticated and cross-user to verify access controls.
Unscoped CRUD Endpoints
highAuto-generated endpoints may return all records instead of scoping to the authenticated user.
Account takeover of legitimate users. Attackers gain full access to victim accounts and any data/actions those accounts permit.
Attempt 20+ login requests with the same username in under 60 seconds. If all complete without rate limiting or lockout, the issue is present.
Enforce email verification, minimum password requirements, and rate limiting on auth endpoints. Test auth flows as unauthenticated and cross-user to verify access controls.
Missing Input Validation
highFunction stacks processing user input without validation are vulnerable to injection.
Session hijacking, data theft, and arbitrary actions executed on behalf of logged-in users. XSS also enables keylogging and credential phishing within your own domain.
Submit test payloads (`<script>alert(1)</script>`, `' OR 1=1 --`) through every user input field. Any reflection or query error confirms the issue.
Use parameterized queries, sanitize all user input, and render dynamic content with framework escaping (React JSX, not dangerouslySetInnerHTML).
Medium Severity Issues
Exposed Instance Tokens
mediumXano API tokens in frontend code grant direct backend access.
Attack surface expansion. In combination with other findings, enables data exposure, account compromise, or service abuse.
Run a VAS scan against the deployed Xano app URL — automated detection is the fastest and most reliable path.
Scan your deployed application with a security tool that understands this stack. Address the specific findings — generic best practices don't catch platform-specific misconfigurations.
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
Find Issues Before Attackers Do
VAS scans your Xano app for all these issues automatically. Scans from $9, instant results.
Get Starter ScanFrequently Asked Questions
What are the most common Xano 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 Xano applications.
How do I find security issues in my Xano 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 Xano security issues fixable?
Yes, nearly all Xano 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 Xano 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 Xano have built-in security?
Xano 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.
