Xano Security Scanner
Built your backend with Xano? No-code doesn't mean no risk. We find the API vulnerabilities and misconfigurations attackers exploit.
Our automated security scanner analyzes your Xano application for vulnerabilities, misconfigurations, and exposed secrets. Get a comprehensive security report in minutes, not days.
Top 4 Security Issues in Xano Apps
Unauthenticated API Endpoints
API groups published without auth middleware allow anyone to read, create, or delete data.
Exposed Instance Tokens
Xano API tokens in frontend code grant direct backend access.
Unscoped CRUD Endpoints
Auto-generated endpoints may return all records instead of scoping to the authenticated user.
Missing Input Validation
Function stacks processing user input without validation are vulnerable to injection.
Where Security Breaks in Xano Apps
Built on Postgres, Xano applications share a recognizable fingerprint, which means attackers and automated scanners find them the same way every time. Based on real vulnerability patterns in Xano deployments, the breakdown is 0 critical-impact issues, 3 high-impact, and 1 medium-or-lower.
Unauthenticated API Endpoints
API groups published without auth middleware allow anyone to read, create, or delete data.
Fix: Enforce email verification, minimum password requirements, and rate limiting on auth endpoints. Test auth flows as unauthenticated and cross-user to verify access controls.
Exposed Instance Tokens
Xano API tokens in frontend code grant direct backend access.
Fix: 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.
Unscoped CRUD Endpoints
Auto-generated endpoints may return all records instead of scoping to the authenticated user.
Fix: 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
Function stacks processing user input without validation are vulnerable to injection.
Fix: Use parameterized queries, sanitize all user input, and render dynamic content with framework escaping (React JSX, not dangerouslySetInnerHTML).
What We Check
API Endpoint Audit
Tests all discovered Xano API endpoints for proper authentication.
Token Exposure
Scans JavaScript bundles for Xano API tokens and instance URLs.
Data Scoping
Verifies API responses are scoped to the authenticated user.
Security Headers
Checks for missing HTTP security headers and CORS issues.
What You'll Get
Why Xano Apps Need Security Scanning
Xano is a popular no-code backend for vibe coders. Its visual function stack builder makes API development accessible, but an endpoint without authentication is just as exploitable whether built visually or in code.
vas scans your deployed application by testing your Xano API endpoints the way an attacker would, probing for unauthenticated access and leaked tokens.
How Xano Security Scanning Works
Submit Your URL
Enter your Xano application URL. Our scanner automatically detects your tech stack and configures the appropriate security checks for Xano.
Automated Analysis
We scan for exposed secrets, security headers, authentication issues, database misconfigurations, and Xano-specific vulnerabilities. A deep scan typically completes in 20-30 minutes.
Get Actionable Results
Receive a detailed report with prioritized vulnerabilities, severity ratings, and step-by-step remediation guidance with code examples specific to Xano.
Common Questions About Xano Security
What vulnerabilities are most common in Xano apps?
The top finding classes in Xano apps: unauthenticated api endpoints; exposed instance tokens; unscoped crud endpoints.
What does a vas scan of a Xano app check?
The scan probes your deployed app for the specific findings above: api endpoint audit, token exposure, data scoping, security headers. It actually attempts each vulnerability class (not just header inspection) and reports results with severity + fix for each.
Is running a scan safe for production?
Yes. The scanner uses read-only probes against public endpoints: no data modification, no destructive tests. A deep scan typically finishes in 20-30 minutes and will not impact application availability.
Remediation Playbook for Xano
Priority-ordered fixes for the specific findings we see in Xano apps. Critical items close data-exposure gaps; high items prevent compromise; medium items reduce attack surface. Applies to apps using Postgres, the dominant Xano stack.
1. Unauthenticated API Endpoints
Why it matters: API groups published without auth middleware allow anyone to read, create, or delete data.
How to close it: Enforce email verification, minimum password requirements, and rate limiting on auth endpoints. Test auth flows as unauthenticated and cross-user to verify access controls.
2. Exposed Instance Tokens
Why it matters: Xano API tokens in frontend code grant direct backend access.
How to close it: 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.
3. Unscoped CRUD Endpoints
Why it matters: Auto-generated endpoints may return all records instead of scoping to the authenticated user.
How to close it: Enforce email verification, minimum password requirements, and rate limiting on auth endpoints. Test auth flows as unauthenticated and cross-user to verify access controls.
4. Missing Input Validation
Why it matters: Function stacks processing user input without validation are vulnerable to injection.
How to close it: Use parameterized queries, sanitize all user input, and render dynamic content with framework escaping (React JSX, not dangerouslySetInnerHTML).
Verify the fixes stuck
Run a vas scan after applying each fix to confirm the gap is actually closed. "I applied the fix" is not evidence. The fix may have been partial, reverted, or not deployed. Re-scanning gives you proof, and a record for compliance if you ever need it.
Secure Your Xano App
Don't let vulnerabilities compromise your hard work. Security issues in Xano applications can lead to data breaches, unauthorized access, and damaged user trust. The average data breach costs startups between $120,000 and $1.24 million.
Run your first scan free, in minutes. Scan before you launch and deploy with confidence knowing your application meets security best practices.
