Base44 manages hosting, database, and auth for you, which hides some risk but not all of it. Security researchers documented real platform flaws, including an open redirect that leaked access tokens, stored cross-site scripting, and premium features enforced only in the browser. The convenience of a managed platform makes it easy to assume everything is secure by default, and that assumption is the risk.
The risks that actually matter
Client-side-only enforcement
Access rules and premium gates that run only in the browser can be bypassed by anyone reading the app. Enforcement has to happen on the server.
Keys in generated integration code
A key inside generated client code can still be extracted from the bundle, even though Base44 manages the backend.
Data exposure through platform flaws
Documented issues meant access tokens and sensitive data were exposed in ways a developer would not see, so managed does not mean audited.
How to secure a Base44 app
- Enforce every access and premium check on the server, never client-only.
- Store keys in Base44's secret configuration, not inline in generated code.
- Rotate any credential that may have been exposed.
- Review what data each key and role can reach.
