6 Security Issues Documented
Common vulnerabilities found in Bubble applications
Critical Security Issues
Missing Privacy Rules
criticalData types without privacy rules configured.
All data of that type exposed to all logged-in users.
Check Data → Privacy for each data type.
Configure privacy rules for EVERY data type immediately.
Public API Workflows
criticalAPI workflows without authentication required.
Anyone can call API endpoints and modify data.
Check 'This workflow requires authentication' setting.
Enable authentication on all API workflows.
High Severity Issues
Plugin Security Risks
highThird-party plugins with data access.
Malicious or vulnerable plugins can expose data.
Audit installed plugins and their permissions.
Remove unused plugins. Only use trusted developers.
Client-Side Logic Exposure
highSensitive workflow logic visible in browser.
Business logic reverse engineering.
Inspect network requests in browser DevTools.
Move sensitive operations to backend workflows.
Medium Severity Issues
Data API Enabled
mediumBuilt-in Data API allowing external data access.
External access to data if privacy rules weak.
Check Settings → General → Data API toggle.
Disable if not needed. Ensure privacy rules are strict.
Visible Database Structure
mediumNetwork requests reveal data type structure.
Attackers can understand database schema.
Inspect network requests for data type information.
Assume structure is known. Rely on privacy rules.
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

Get Starter ScanFrequently Asked Questions
What are the most common Bubble 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 Bubble applications.
How do I find security issues in my Bubble 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 Bubble security issues fixable?
Yes, nearly all Bubble 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 Bubble 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 Bubble have built-in security?
Bubble 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.
