Xano Security Scanner
Built your backend with Xano? No-code doesn't mean no risk. We find the API vulnerabilities and misconfigurations attackers exploit.
Enter your deployed app's URL. Review the findings, take the suggested fixes to your coding tool, and retest after making changes.
First scan free: issue counts and one finding revealed in detail. No card required.
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 check the reachable app for exposed secrets, browser protections, authentication issues and database access problems. A standard scan typically takes a few minutes; blocked requests or incomplete coverage are reported.
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 does a VAS scan of a Xano app check?
VAS checks the deployed pages, scripts and endpoints it can reach for issues including api endpoint audit, token exposure, data scoping, security headers. The report records findings and coverage limits; it does not certify the whole app as secure.
What will I receive in the report?
Findings include severity, supporting evidence and remediation guidance. Your first scan is free, with issue counts and one finding revealed in detail. Paid report access unlocks every finding. Use Export for AI to bring available findings into your coding tool, review the proposed changes and retest.
Can a scan verify every permission and private workflow?
No. Coverage depends on reachable pages, discovered endpoints and enabled checks. Configure a test login for supported authenticated checks. Review source code and business-specific permissions separately. Zero findings does not prove an app is secure.
Does VAS change my code or database policies?
VAS provides recommendations, not automatic fixes. Adapt any suggested policy or code change to your data model, test that permitted users still have access and that other users do not, then rescan. Read checks alone cannot confirm insert, update or delete permissions.
What should I know before scanning a production app?
Only scan apps you own or have permission to test. Scan requests can trigger firewall rules, logs and rate limits. Review enabled checks, and use staging or dedicated test accounts for sensitive workflows. Active tests, where enabled, need separate care because they can make changes.
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
Rescan after deploying a fix to check whether the original finding still appears. Compare the evidence and coverage with the previous report. For permissions and private workflows, also repeat the relevant tests with authorized and unauthorized test users.
