Webflow Security Scanner
Building with Webflow? Ensure your CMS and custom integrations are secure.
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.
Webflow Security Considerations
Webflow makes development fast, but AI-generated code often skips security best practices:
- !CMS field visibility settings
- !Form submission security
- !Custom code injection risks
- !Third-party integration security
Where Security Breaks in Webflow Apps
Built on a managed backend, Webflow applications share a recognizable fingerprint, which means attackers and automated scanners find them the same way every time. Based on real vulnerability patterns in Webflow deployments, the breakdown is 0 critical-impact issues, 2 high-impact, and 3 medium-or-lower.
Custom Code XSS
Pasted JavaScript embeds can introduce XSS vulnerabilities.
Fix: Audit all custom code embeds. Only paste from trusted sources.
CMS Content Visibility
CMS data may be exposed in page source if visibility not configured.
Fix: Configure Collection visibility settings. Don't store secrets in CMS.
Third-Party Script Risks
Embedded scripts have full page access.
Fix: Review all third-party scripts. Minimize external dependencies.
Form Data Handling
Forms lack server-side validation—client-only checks.
Fix: Use Webflow integrations for processing. Don't collect sensitive data.
Missing Security Headers
Custom security headers require manual configuration.
Fix: Add headers via custom code or Cloudflare proxy.
What We Check

What You'll Get
Why Webflow Apps Need Security Scanning
Webflow combines visual design with CMS capabilities. Understanding security implications of CMS settings and custom code helps protect your site.
vas scans your Webflow site for security headers, exposed data, and custom code vulnerabilities.
How Webflow Security Scanning Works
Submit Your URL
Enter your Webflow application URL. Our scanner automatically detects your tech stack and configures the appropriate security checks for Webflow.
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 Webflow.
Common Questions About Webflow Security
What does a VAS scan of a Webflow app check?
VAS checks the deployed pages, scripts and endpoints it can reach for issues including cms security, form security, custom code, 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 Webflow
Priority-ordered fixes for the specific findings we see in Webflow apps. Critical items close data-exposure gaps; high items prevent compromise; medium items reduce attack surface. Applies to apps using a managed backend, the dominant Webflow stack.
1. Custom Code XSS
Why it matters: Pasted JavaScript embeds can introduce XSS vulnerabilities.
How to close it: Audit all custom code embeds. Only paste from trusted sources.
2. CMS Content Visibility
Why it matters: CMS data may be exposed in page source if visibility not configured.
How to close it: Configure Collection visibility settings. Don't store secrets in CMS.
3. Third-Party Script Risks
Why it matters: Embedded scripts have full page access.
How to close it: Review all third-party scripts. Minimize external dependencies.
4. Form Data Handling
Why it matters: Forms lack server-side validation—client-only checks.
How to close it: Use Webflow integrations for processing. Don't collect sensitive data.
5. Missing Security Headers
Why it matters: Custom security headers require manual configuration.
How to close it: Add headers via custom code or Cloudflare proxy.
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.
Check your Webflow app
Find observable security issues in your deployed app, review the evidence and take the next steps with your coding tool.
Start with a free scan. See issue counts and one finding in detail, then decide whether you need full report access.
