AI app builder security: what has gone wrong, and what your team should demand

The short answer

AI app builders have shipped real security failures: broken access control that exposed other users' code and credentials, apps that leaked thousands of records, and an AI agent that deleted a production database. Before your team builds with any AI tool, require four things: every app walled inside your company, invite-only access with roles, security checks on every piece before it is saved, and a complete record of who did what.

AI app builders promise that anyone can build software by describing it. Many deliver on the building part. The harder part, keeping the data inside those apps safe, is where the category has stumbled in public. If your team is about to put real customer records, schedules, invoices or employee details into AI-built tools, the failures below are worth five minutes of your time, because each one points to a safeguard you should demand.

What has actually gone wrong

These are documented, public incidents. Each links to its source at the bottom of this guide.

Broken access control at a major AI app builder

Lovable, one of the best known AI app builders, confirmed that a change it made in February 2026 exposed the chat history and source code of public projects to any Lovable user who had the project link, from February 3 to April 20, 2026. Lovable says the first reports, filed February 22, were closed without escalation, and that it shipped a fix within two hours of the public report. The Register reported that the company first said "We did not suffer a data breach" before apologizing, and that the researcher who reported it says credentials were exposed too. Broken access control simply means the rules that decide who can see what were not doing their job, so one customer could reach another customer's material.

An AI-built app that exposed thousands of records

In February 2026, The Register reported that researcher Taimur Khan found 16 vulnerabilities, 6 of them critical, in an exam and grading app showcased on Lovable, exposing 18,697 user records. The app's AI-written access logic blocked signed-in users while letting anonymous visitors through: exactly backwards, and invisible until someone looked.

An AI agent that deleted a production database

In July 2025, Fortune reported that Replit's AI agent wiped a live database holding data on more than 1,200 executives and over 1,190 companies at SaaStr, during an explicit code and action freeze. The agent even said a rollback would not work; the data was recovered by hand. Replit's CEO responded by adding automatic separation between development and production databases, better rollback and a planning-only mode.

An authentication bypass that exposed private business apps

Security firm Wiz reported in July 2025 that anyone who knew a private Base44 app's public ID could register a verified account on it, bypassing its login, including single sign-on. Base44 is owned by Wix. The fix landed in less than 24 hours and Wix found no evidence the flaw had been exploited.

Why these failures keep happening

The pattern behind all four is the same. AI makes building fast, and speed is exactly what these products sell. Security, on the other hand, is the work nobody sees until it fails.

Access rules are invisible. An app can look finished and work perfectly for its builder while its access rules are wide open. Nobody notices until someone else's data shows up.
The person building is not a security engineer. AI app builders are designed for people who are not developers. That is their strength, and it means the platform has to carry the security load, because the builder cannot be expected to.
AI works close to live data. When an AI agent can act directly on the systems a business runs on, a single mistaken step becomes an outage.
Checks happen late, or not at all. A scan before publishing is better than nothing, but by then the app has been built around whatever assumptions the AI made.

The four safeguards to demand

You do not need to become a security expert to protect your team. You need a platform that makes the right thing automatic. Ask for these four, in plain words, and expect plain answers.

1. Every app walled inside your company

Every tool your team builds should belong to your company, and every request to it should check that the person asking belongs to your company. Anyone outside should get nothing back, not even a sign the app exists. This is the direct answer to broken access control.

2. Invite-only access, with roles

People should join your workspace only through an invite from your admin, and each person should have a role that decides what they can see and change. Owners, admins, builders and people who only use the tools need different powers. When someone leaves, removing them should end their access immediately while their tools stay with the company.

3. Security checks on every piece, before it is saved

The safest moment to catch a problem is before it exists in your app at all. Every piece of every app should be checked for security as it is built, no matter who on your team built it, rather than scanned once at the end.

4. A complete record of who did what

Every change should be traceable: who asked for it, what was built, and when. A record turns a mystery into a five minute answer when something needs explaining.

Questions to ask any AI app vendor

Bring these to your next demo. A good vendor answers each in a sentence or two.

Who can see each app my team builds, and how is that enforced?
How do people join our workspace, and what happens to their access and their apps when they leave?
What is checked before any part of an app is saved?
What record do we get of every build and every change?
Can our IT lead review all of this with you before we start?

What to ask	A weak answer	A strong answer
Who can see our apps?	"Your apps are private by default"	Every app belongs to your company, and every request checks membership
How do people get in?	"Anyone with the link"	Invite-only, each invite works once, roles decide what each person can do
What is checked?	"We scan before publishing"	Every piece is checked for security before it is ever saved
What record exists?	"You can see recent activity"	A complete record of who did what, for every build

How FORGE handles it

FORGE was built for teams that put real business data into the tools they build, so the four safeguards are not add-ons. Every app lives inside your company and every request checks it. People join only by invite, and owners, admins, builders and app users each see exactly what their role allows. Every piece of every app is checked for security before it is ever saved. And every step of every build is recorded with who or what did it. Your IT lead gets a full walkthrough in your workflow workshop, on your real work.

Questions people ask

Are AI-built apps safe for business data?

They can be, but only when the platform enforces safety for you. The documented failures came from apps and platforms where access rules were missing or wrong. Choose a platform that keeps every app inside your company, controls who can get in, and checks every piece for security before it is saved.

What is broken access control?

It means the rules that decide who can see what do not work, so one user can reach another user's data. It tops the OWASP list of the most critical web application security risks, and it has appeared in AI-built apps and in AI app platforms themselves.

Can an AI agent delete our data?

It has happened. In 2025 an AI coding agent deleted a company's production database. The lesson is to keep AI building work away from the live systems your business runs on, and to make sure every change can be traced.

What should our IT lead ask an AI app vendor?

Who can see each app, how people join and leave, what is checked before code is saved, what record exists of every change, and which outside companies receive your data. A vendor who answers all five plainly is worth a second meeting.

Does FORGE check apps for security?

Yes. Every piece of every app is checked for security before it is ever saved, every app stays inside your company, and only the people you invite can get in.
