Base44 owns the backend. Permissions are still yours.

Security Scanner forBase44 Apps

Base44 built its own backend instead of wiring up Supabase or Firebase, so there's no anon key to leak. But every entity still ships with a permission rule you have to get right, and the platform itself has already had one critical authorization bug of its own. ShipSafe verifies what it can see from the outside, and walks you through the rest.

The short answer

Why Base44 Apps Need An Outside Check

Base44 is not another Supabase wrapper. Its founder built the whole stack — frontend, backend, database, auth, and hosting — from the ground up rather than stitch together third-party services, and Wix acquired the company in 2025 for exactly that vertical integration. It's a real architectural difference from Lovable, Bolt, and most of the AI-builder category, and it changes what a security check needs to look at.

Because there's no client-exposed database key, the classic “grep the anon key, check RLS” approach doesn't apply here. The risk moves to Base44's own permission model: every entity ships with a CRUD access rule you configure, and Base44's own guidance is blunt about what happens when that rule is left open. The platform itself has also shipped an authorization bug of its own — in July 2025, Wiz Research disclosed a critical SSO bypass in two of Base44's endpoints, patched within 24 hours.

None of that makes Base44 unusually risky as a builder. It means the checklist is different from a Supabase stack, and it's worth running once before you ship. See how this compares to other builders in the vulnerabilities by platform reference.

Common vulnerabilities

Where Base44 Apps Actually Get Exposed

Base44 owns its backend end-to-end, so there's no anon key or RLS policy to check. The real exposure lives in entity permissions and endpoint authorization.

  1. Default-Open Entity Permissions

    Critical

    Every entity Base44 generates carries its own CRUD-level access rule — public, authenticated, creator-only, or role-based — and Base44's own documentation is direct about the risk: if those rules aren't set correctly, the wrong people could view or change data in your app. Base44's security guidance names the most common failure outright: setting an entity to 'No restrictions' to get it working during development, then never coming back to tighten it before launch.

  2. Authentication Bypass via Undocumented App Endpoints

    Critical

    In July 2025, Wiz Research disclosed two unauthenticated Base44 platform endpoints — a registration route and an OTP-verification route — that let anyone create a verified account on someone else's private, SSO-protected app using only its app_id, a non-secret value visible in the app's URL and manifest file. Wix patched it within 24 hours of disclosure and found no evidence of exploitation, but it shows that on a platform-owned backend, an authorization gap doesn't stay contained to one app.

  3. API Keys and Secrets Reaching the Client Bundle

    High

    Base44 gives you a Secrets vault and proxies certain integration calls through its own backend so keys never touch the browser — but only for integrations wired that way. Base44's own Security Scan explicitly checks generated code for hardcoded secrets like exposed API keys, which is a fair signal for how often a key ends up pasted into a prompt or a client-side fetch instead of the vault.

  4. Broken Authorization on Generated CRUD Endpoints (IDOR)

    High

    Base44 generates a full read/create/update/delete API for every entity you create, and each operation gets its own access rule. It's easy to lock down the screens a user sees in the UI while leaving the underlying operation open, so a logged-in user — or anyone who can guess or enumerate a record ID — can call the endpoint directly and reach records that were never meant to be theirs.

How ShipSafe Verifies Your Base44 App

1

Verify Your Live App From the Outside

ShipSafe checks your deployed Base44 app the way an outsider would: TLS and certificate health, security headers, and — with your explicit consent — whether the endpoints Base44 generated respond to an unauthenticated request the way they should.

2

Walk the Base44 Permission Checklist

Entity permissions live inside Base44's own dashboard, not in a file ShipSafe can read. So ShipSafe walks you through every entity's access rule against Base44's own model — public, authenticated, creator-only, role-based — and you confirm what only you can see.

Get an Honest Report and a Verified Badge

External findings and your self-attested checklist combine into one severity-ranked report. Fix what's open, and ShipSafe issues a verification badge that re-checks itself on a rolling window.

Frequently Asked Questions

Does Base44 use Supabase or Firebase like other AI builders?
No, and this is the biggest architectural difference in the category. Where Lovable, Bolt, and most AI builders wire your app up to Supabase or Firebase, Base44's founder made the deliberate choice to build the entire backend — database, auth, and hosting — from the ground up instead of integrating a third-party provider. That means there's no anon key sitting in your frontend bundle and no RLS policy to write. It also means the security boundary that matters is Base44's own permission model, not a Postgres row-level policy.
What was the Base44 vulnerability Wiz Research found?
In July 2025, security firm Wiz disclosed a critical authentication bypass affecting Base44's platform. Two endpoints — one for registering a new account, one for verifying it by OTP — didn't check whether the caller was actually authorized for the app in question. All an attacker needed was the app's app_id, a value visible in its URL and manifest file, to create a verified account on a private, SSO-protected app and reach whatever it exposed. Wiz reported the issue on July 9, 2025; Wix (Base44's parent company) shipped a fix within 24 hours and reported no evidence the bug was exploited before it was patched.
Is my Base44 app secure by default?
Assume it isn't until you've checked. Base44 automatically sets some data permissions as it builds your app, but it doesn't guarantee they're the right ones for handling real user data — its own documentation warns that misconfigured permissions let the wrong people view or change your data, and its security guide names the most common mistake outright: setting an entity to 'No restrictions' to make it work, then never tightening it. Base44 owning the backend removes one class of mistake, a leaked database key. It doesn't remove the permission layer, and that layer is still yours to get right.
Can ShipSafe scan my Base44 app?
Partially, and we'd rather tell you exactly where the line is than oversell it. Base44's backend is proprietary: there's no Supabase migration file or exposed anon key for ShipSafe to read, and the entity permission matrix lives inside Base44's own dashboard, not in a repo. What ShipSafe can do: verify your live app from the outside — TLS and certificate health, security headers, and, with your consent, whether specific endpoints respond to an unauthenticated request the way they should. If you've connected your app to GitHub through Base44's own sync feature, ShipSafe can also scan that synced frontend code for hardcoded secrets and other client-side exposure, the same way it scans any repo. What it can't do is reach into Base44's permission panel for you. That check runs through a guided checklist matched to Base44's own CRUD and role model, and you attest what you found. Combined, that's an honest, independently verified picture, not a claim that we silently audited a backend we can't see.
How do I fix Base44 permission and endpoint issues?
Start with Base44's own advice, which is sound: default every entity to the most restrictive access level that still lets your app function, then loosen only what you've confirmed needs to be open. Walk every entity, not just the ones you remember creating, since it's the forgotten ones that stay on 'No restrictions.' Test as a logged-out, unauthenticated user and confirm you can't read or write data that isn't yours. Move any API key that isn't already in Base44's Secrets vault out of client-side code. And keep an eye on Base44's own changelog and security advisories: as the July 2025 Wiz disclosure showed, the platform moves fast to patch its own bugs, but a patch doesn't retroactively lock down an entity you left open.
