Bubble Security Checklist
Last updated: January 12, 2026
Use this checklist to ensure your Bubble application is secure before launch. 4 critical items require immediate attention.
Why This Security Checklist Matters
Security checklists serve as systematic guides for identifying vulnerabilities that might otherwise be overlooked during rapid development cycles. For Bubble applications specifically, this checklist addresses the most common security gaps that emerge when using AI-assisted development workflows.
Research from multiple security organizations indicates that approximately 80% of AI-built applications contain at least one exploitable vulnerability at launch. The vulnerabilities are often predictable—they follow patterns that this checklist is designed to catch. By systematically reviewing each item, you significantly reduce the risk of launching an insecure application.
Unlike generic security checklists, this guide focuses specifically on vulnerabilities prevalent in Bubble applications. Each item has been prioritized based on real-world attack patterns and the potential impact of exploitation. Critical items should be addressed before any production deployment.
Critical Priority
Critical items can lead to complete application compromise, data breaches, or unauthorized access to all user accounts. These must be addressed before deploying to production. Attackers actively scan for these vulnerabilities.
High Priority
High priority items represent significant security risks that could allow unauthorized access to sensitive data or functionality. While not immediately catastrophic, these vulnerabilities should be fixed as soon as possible.
Medium/Low Priority
Medium and low priority items strengthen your overall security posture. While they may not be immediately exploitable, addressing them prevents attack chains and defense-in-depth gaps.
Manual vs Automated Security Checking
While manual security reviews are thorough, they're time-consuming and prone to human error. Automated scanning catches common vulnerabilities instantly, freeing you to focus on business logic and complex security decisions.
Items VAS Automates
- Exposed API keys and secrets in JavaScript bundles
- HTTP security header configuration
- Supabase RLS policy testing
- Firebase Security Rules validation
- Cookie security attributes
Manual Review Still Required
- Business logic vulnerabilities
- Custom authentication implementations
- Access control logic in API routes
- Data validation requirements
- Third-party integration security
Privacy Rules
Configure privacy rules for all data types
Every data type should have explicit privacy rules defining access
Test privacy rules as different user roles
Verify rules work by testing as logged out, regular user, and admin
Don't rely on 'everyone' privacy level for sensitive data
Avoid public access to user data, financial info, or PII
Use 'This Thing's Creator' pattern
Restrict data access to the user who created it where appropriate
Review search constraints
Ensure searches respect privacy rules and don't leak data
API Workflow Security
Secure API workflows with authentication
Don't expose API workflows that modify data without auth
Use authentication tokens for API calls
Implement token-based auth for external API access
Validate input in workflows
Check data types and constraints in workflow logic
Rate limit API endpoints
Prevent abuse by limiting API call frequency
Plugin Security
Audit installed plugins
Review what data and permissions each plugin requires
Only use plugins from trusted developers
Check plugin reputation and reviews before installing
Remove unused plugins
Uninstall plugins you're not actively using
Keep plugins updated
Update plugins to get security fixes
General Security
Enable SSL (automatic for paid plans)
AutoEnsure HTTPS is enforced for your Bubble app
Configure option sets carefully
Option sets are often public - don't put secrets in them
Review page access rules
Configure which pages require login
Test with browser developer tools
Check what data is exposed in network requests
Don't Check Manually

How do Bubble privacy rules work?
Privacy rules define who can view and modify each data type. You can base access on user roles, ownership ('This Thing's Creator'), or custom conditions. Rules are enforced server-side, so they can't be bypassed from the frontend.
Can users bypass privacy rules?
Properly configured privacy rules cannot be bypassed - they're enforced server-side. However, rules that check client-side conditions or rely on hidden fields can potentially be exploited. Test your rules by logging in as different user types.
