Why Security Matters for Bubble

Key Security Concerns

Privacy rules buried in Data → Privacy tab - easy to miss entirely

API workflows are PUBLIC by default - anyone can call them

Visual builder hides security settings behind multiple menus

Third-party plugins have access to your data with varying security

Database structure visible to anyone who inspects network requests

Security Strengths

Built-in user authentication with SSO options

Privacy rules system (like RLS for no-code)

Hosted on AWS with automatic SSL

Version control and rollback capabilities

SOC 2 Type II certified on paid plans

Known Security Incidents

Widespread Privacy Rule Misconfigurations

high

Ongoing

Security researchers regularly find Bubble apps with missing privacy rules, exposing user data. Unlike code-based apps where you explicitly write queries, Bubble's visual nature makes it easy to forget privacy rules exist.

Step-by-Step Security Guide

1. Configure Privacy Rules

Every data type needs privacy rules. Without them, data may be accessible to any logged-in user.

2. Use Backend Workflows

Move sensitive logic (payments, data modifications) to backend workflows. Client-side workflows can be inspected.

3. Protect API Endpoints

Add authentication checks to all API workflow triggers. Don't expose unauthenticated endpoints.

4. Test Privacy Rules

5. Secure Form Inputs

Validate inputs in workflows. Never trust client-side data validation alone.

6. Audit Plugins

Review installed plugins for security. Only use plugins from trusted developers.

Common Security Mistakes

Avoid these common Bubble security pitfalls:

Missing privacy rules on data types

Sensitive logic in client-side workflows

Unauthenticated API endpoints

Trusting client-side validation

Installing untrusted plugins

Frequently Asked Questions

Are Bubble privacy rules secure?

Yes, privacy rules are evaluated server-side and can't be bypassed from the client. The key is configuring them correctly for every data type.

Can users see my workflow logic?

Users can see client-side workflow structure (not all details) in browser dev tools. That's why sensitive operations should use backend workflows which are fully server-side.
