Base44 handles hosting, database, and auth for you, which hides some risk but not all of it. Keys can still end up in generated integration code, and security researchers have documented real platform flaws, including an open redirect that leaked access tokens, stored cross-site scripting, and premium features enforced only on the client. If a key was exposed, rotate it first, then check what it could reach.
Why it's a problem
Because Base44 manages the backend, it is easy to assume everything is secure by default, and that assumption is the risk. A key inside generated integration code can still be extracted from a client bundle, and documented platform issues meant access tokens and data were exposed in ways a developer would not see. Client-side-only enforcement means checks can be bypassed by anyone reading the app.
How to fix it, in order
- 1Rotate any exposed key. Regenerate it at the provider. If a Base44-managed credential was exposed, rotate it through the Base44 settings.
- 2Move keys into Base44's secret storage. Use the platform's environment or secret configuration rather than inline values in generated code, so keys are not in the client bundle.
- 3Enforce access checks on the server. Any premium gate or authorization check that only runs in the browser can be bypassed. Make sure the enforcement happens in the backend, not just the UI.
- 4Review what the exposed key could access. Check logs for unexpected use and treat any data the key could read as potentially accessed.
Why Base44 does this
Base44 generates a full working app from a prompt, and when an integration needs a key the fastest path to a running app is to place it where the generated code can reach it. The platform doing so much automatically also means security-relevant details are hidden, so an exposed key or a client-only check is easy to miss.
Stop it happening again
Do not assume a managed platform means a secure app. Keep keys in Base44's secret storage, enforce every access rule on the server, and scan the app for inline secrets before you share or launch it.
The quick fix
- Rotate any exposed key at the provider or in Base44 settings.
- Store keys in Base44's secret configuration, not inline in generated code.
- Enforce premium and auth checks server-side, never client-only.
- Review logs for use the exposed key may have enabled.
