Can Bubble apps be hacked?

Bubble-Specific Attack Vectors

These are the paths attackers actually take into Bubble applications — not a generic OWASP list, but what automated scanners and security researchers find when they look at Bubble apps specifically, given the stack (a hosted backend):

1. **Missing Privacy Rules**: Data types without privacy rules expose all data to all users.

2. **Public API Workflows**: API workflows are public by default—anyone can call them.

3. **Plugin Security Risks**: Third-party plugins have access to your data with varying security.

4. **Visible Database Structure**: Network requests reveal database schema to inspecting users.

5. **Client-Side Logic Visibility**: Workflow logic partially visible in browser developer tools.

Real-world example

Security researchers regularly find Bubble apps with fully exposed databases.

How these issues get discovered

This isn't targeted — automated scanners run across the entire internet looking for known patterns, and Bubble apps surface like everything else. Your hosting provider's fingerprint in response headers makes the underlying stack easy to identify. Once identified, the scanner probes the specific vulnerability classes listed above.

What a security scan of a Bubble app looks at

• **Privacy Rules** — Test privacy rule effectiveness.
• **API Workflows** — Check workflow authentication.
• **Data Security** — Review data type settings.
• **Plugin Security** — Analyze plugin configurations.
