4 Security Issues Documented
Common vulnerabilities found in Webflow applications
High Severity Issues
Custom code injection risks
highA common failure mode in Webflow applications: custom code injection risks. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
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.
Use parameterized queries, sanitize all user input, and render dynamic content with framework escaping (React JSX, not dangerouslySetInnerHTML).
Medium Severity Issues
CMS field visibility settings
mediumA common failure mode in Webflow applications: cms field visibility settings. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
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.
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.
Form submission security
mediumA common failure mode in Webflow applications: form submission security. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
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.

Third
mediumparty integration security
Attack surface expansion. In combination with other findings, enables data exposure, account compromise, or service abuse.
Run a VAS scan against the deployed Webflow app URL — automated detection is the fastest and most reliable path.

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 Webflow app for all these issues automatically. Scans from $9, instant results.
Get Starter ScanFrequently Asked Questions
What are the most common Webflow 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 Webflow applications.
How do I find security issues in my Webflow 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 Webflow security issues fixable?
Yes, nearly all Webflow 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 Webflow 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 Webflow have built-in security?
Webflow 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.
