Webflow Security Scanner
Building with Webflow? Ensure your CMS and custom integrations are secure.
Our automated security scanner analyzes your Webflow application for vulnerabilities, misconfigurations, and exposed secrets. Get a comprehensive security report in minutes, not days.
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
CMS Security
Review CMS field settings.
Form Security

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.

Common Questions About Webflow Security
What vulnerabilities are most common in Webflow apps?
The top finding classes in Webflow apps: custom code xss; cms content visibility; third-party script risks.
What does a VAS scan of a Webflow app check?
The scan probes your deployed app for the specific findings above: cms security, form security, custom code, 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. Scans typically finish in 15–20 minutes and will not impact application availability.
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
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 Webflow App
Don't let vulnerabilities compromise your hard work. Security issues in Webflow 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.
