Base44 security

Database Tables Publicly Accessible Without Authentication

Your Base44 app's database tables are readable by anyone, even unauthenticated visitors. Personal information, email addresses, passwords, payment details, and private business data are all accessible by directly querying the database through the app's API layer.

This happens because Base44's default table configuration may not enforce access restrictions, or the access rules were misconfigured during setup. Anyone who discovers the API endpoint or inspects network requests can pull all records from any table.

You might discover this when a user reports seeing other users' data, when you find your data indexed by search engines, or during a security review that reveals all tables are open.

Error Messages You Might See

Common Causes

  • Default table permissions left open — Base44 tables are created without row-level or table-level access restrictions enabled
  • No authentication required for read operations — The data API allows GET requests without any auth token or session
  • API endpoints exposed in frontend code — Network requests visible in browser DevTools reveal direct database query endpoints
  • Access rules only on UI, not data layer — Page-level restrictions hide the UI but the underlying data endpoints remain accessible
  • Admin tables not separated — Sensitive admin data lives in the same unrestricted tables as public content

How to Fix It

  1. Audit all table permissions — Go through every table in your Base44 dashboard and check who has read, write, and delete access
  2. Enable authentication on all data endpoints — Require a valid session or API token for any data read or write operation
  3. Implement row-level access — Configure rules so users can only read and modify their own records
  4. Separate public and private tables — Keep truly public content (blog posts, product listings) in separate tables from private data (users, orders)
  5. Test as an unauthenticated user — Open your app in an incognito window and check what data you can access without logging in

Frequently Asked Questions

How do I check if my Base44 tables are publicly accessible?

Open your app in an incognito browser window without logging in. Try accessing data pages or inspect network requests in DevTools. If you can see table data without authentication, your tables are public.

Can I restrict access to specific fields within a table?

Base44 typically allows table-level and row-level access rules. For field-level restrictions, you may need to create separate tables for sensitive fields and apply stricter access rules to those tables.
