Base44 Security Scan: Find and Fix the Holes in Your AI-Built App

Base44's own docs say it in one line, and I respect them for it: you are responsible for your app's security. No AI builder, Base44 included, will hand you a guarantee. What Base44 does hand you is something most no-code platforms still don't: a security scanner built into every app, on every plan, free tier included, that explains each finding and fixes it with your approval.

If you vibe-coded your app in a weekend, this is the fifteen-minute ritual that makes sure you shipped your product and not somebody else's data. If you want to try it on your own app, start here: Base44.

Why Base44's scanner matters more than most

Speed is the whole point of AI building. Speed is also how security debt happens: a data table created with default permissions, an API key pasted where a visitor's browser can read it, a backend function anyone can call with a curl command. The traditional answer is a security review you can't afford. Base44's answer is the security scan, which checks your app for exactly the failure modes AI-built apps tend to have:

• Data permission issues: tables missing permission rules, or people with more access than they should have
• User field access: app users changing their own profile fields to inherit access they shouldn't have
• Exposed secrets: API keys, passwords or tokens sitting where visitors could read them
• Unauthenticated backend functions: functions a stranger can call without signing in
• Credit protection: AI or email features reachable from outside your app, so someone else can spend your integration credits
• App dependencies: third-party libraries with known vulnerabilities, with the recommended version to upgrade to
• Code vulnerabilities: patterns in your app's code like missing access checks or unsafe handling of user input
• Security headers: browser-level protections like X-Frame-Options and Permissions-Policy

That list is not a marketing summary. It is the docs' own category list, and each one comes with a recommended fix you can apply in a click.

Step 1: Run the scan in Base44

1. Open your app's editor and click Dashboard.
2. Click Security.
3. Click Run Security Scan.

Each area shows Checking while it runs, and results appear section by section as they finish, so you can start reviewing before the whole scan completes. If an area shows Not checked, run the scan again. The publish panel also shows your app's Security status: No risks, Out of date with a Scan button, or Risks found. It warns you, though it does not stop you from publishing, which is worth knowing about yourself before your users find out the hard way.

Step 2: Read your findings the right way

Switch between the By category and By severity views to triage. The docs' severity scale runs Critical, High, Medium, Low. Code vulnerability findings go deeper than a label: each one shows an impact statement, the security category it maps to (think OWASP Top 10, CWE numbers), the evidence in your code, an attack scenario walking through how it could be exploited, and a suggested fix. That is the level of explanation I used to pay a consultant for, and it is the part that makes the fixes trustworthy, because you can see the reasoning instead of taking the AI's word for it.

Step 3: Fix deliberately, not blindly

The scan never applies fixes automatically. Every fix is your call:

1. Fix all applies every recommended fix at once (severity view), or fix a whole group at once (category view).
2. Fix N selected applies fixes only to the issues you picked.
3. Expand a single issue to review and fix it on its own.

Three rules from the docs that I would underline twice. First, review each recommendation before applying it. Second, if you changed your app after the last scan, the page shows Rescan to apply fixes and disables fix buttons; run the scan again so every fix works from current results. Third, when you apply any fix, Base44 records it as a message in your app's AI chat and creates a checkpoint first, so if a fix does something unexpected you can revert from that checkpoint. Every security change to your app has a paper trail.

Step 4: Know the two fixes that can break real pages

The docs are unusually honest here, so I'll pass it on unchanged. If your app doesn't require login, a data permissions fix can break a page where visitors look up something they submitted, like a booking, without signing in. When that happens, the fix's message in the AI chat shows Fix the visitor lookup page, which sends the AI a ready-made request to repair that page while keeping records private. Similarly, fixing an Anyone can run this function backend function makes it require a signed-in user, which can break signed-out pages, webhooks or external integrations that call it. Test those paths and rescan. Base44 tells you where the sharp edges are. Most platforms don't.

Step 5: Acknowledge what's intentional

Some findings aren't mistakes. Apps without login are expected to expose backend functions, and the riskier ones get flagged High anyway. Use the More actions icon on an issue and select Acknowledge: it moves to the Acknowledged section and stops reappearing on future scans. Restore it any time. Acknowledging a real risk is a decision; ignoring a warning you never read is not.

Step 6: The new bit, and my favorite update this month

Here is what changed recently, straight from the product changelog. When you ask the AI to fix a security finding, Base44 now checks whether the problem can actually be reached before it changes anything. If nothing can exploit it, the finding is cleared with an explanation instead of a code change. The docs add the fine print: a finding cleared this way is removed from your scan results and from your workspace counts, and if that code changes later, the scan can flag it again. That is the right instinct. Security work should reduce risk, not generate busywork and break working code to satisfy a linter.

For teams: the Security Center, and the new scheduled scans

Solo builders can stop at Step 6. If you run a workspace with a pile of apps, Base44's Security Center is a workspace-wide dashboard for owners and admins on Business and Enterprise plans. It ranks the riskiest apps first, lets you filter by risk level, scan state, visibility, stored secrets, connectors and more, and from each app row you can notify the owner, transfer ownership, or unpublish an app on the spot.

The newest piece, added October 22, is scheduled scans. Turn on a weekly run (up to 200 apps) or a monthly run (up to 500), and Base44 rescans automatically, but only the apps that changed since their last scan, starting with the riskiest. Each run typically uses about 1 to 2 credits per app scanned, apps that haven't changed are skipped and cost nothing, and run history with statuses and credit use is kept for 90 days.

Limitations, stated plainly

I promised no marketing copy, so here is what the docs say you don't get:

• The app-level scan is on all plans, including free. But code vulnerability scanning requires the Builder plan or above, and the Security Center needs Business or Enterprise, with scheduled scans on Enterprise only.
• Bulk scans run on up to 20 apps at a time, and only one bulk scan can run in a workspace at once.
• You can notify an app's owners at most once every 24 hours, up to 20 apps at a time, and only for apps that have been scanned and have open risks.
• Scheduled scans exclude agents, Superagents and Base Code apps.
• Publishing is never blocked by risks, only warned about.
• Data tables and private apps are encrypted, but the docs are explicit that data is not end-to-end encrypted and Base44 admins can access your data if needed.

What you end up with

A repeatable ritual, not a one-time panic: scan before your first publish, rescan after anything significant (new tables, changed permissions, new integrations), acknowledge what's deliberate, and keep the browser security settings in your app's Browser Security card tightened. Teams on Enterprise can set the weekly schedule and forget it. You get the record of every fix in the AI chat, checkpoints to revert anything that misbehaves, and for the full picture, a CSV export of your workspace inventory from the Security Center.

Our take

The insecurity of AI-built apps is a real and growing conversation, and most platforms respond with a shrug and a security disclaimer. Base44 built the opposite: a scanner that explains itself, fixes with your approval, keeps a paper trail, and just got smart enough to stop chasing findings nobody can actually exploit. If you're shipping real products with AI, run this before your users do.
