6 Security Issues Documented

Common vulnerabilities found in Bubble applications

2 Critical2 High2 Medium

Critical Security Issues

Missing Privacy Rules

critical

Data types without privacy rules configured.

Impact

All data of that type exposed to all logged-in users.

How to Detect

Check Data → Privacy for each data type.

How to Fix

Configure privacy rules for EVERY data type immediately.

Public API Workflows

critical

API workflows without authentication required.

Impact

Anyone can call API endpoints and modify data.

How to Detect

Check 'This workflow requires authentication' setting.

How to Fix

Enable authentication on all API workflows.

High Severity Issues

Plugin Security Risks

high

Third-party plugins with data access.

Impact

Malicious or vulnerable plugins can expose data.

How to Detect

Audit installed plugins and their permissions.

How to Fix

Remove unused plugins. Only use trusted developers.

Client-Side Logic Exposure

high

Sensitive workflow logic visible in browser.

Impact

Business logic reverse engineering.

How to Detect

Inspect network requests in browser DevTools.

How to Fix

Move sensitive operations to backend workflows.

Medium Severity Issues

Data API Enabled

medium

Built-in Data API allowing external data access.

Impact

External access to data if privacy rules weak.

How to Detect

Check Settings → General → Data API toggle.

How to Fix

Disable if not needed. Ensure privacy rules are strict.

Visible Database Structure

medium

Network requests reveal data type structure.

Impact

Attackers can understand database schema.

How to Detect

Inspect network requests for data type information.

How to Fix

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

Frequently 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.
