What are common security mistakes in Base44 apps?
Get instant answers about your app's security.
Short Answer
The mistakes we see repeatedly in Base44 apps: exposed api keys; database exposure; missing security headers. Each one is a specific failure mode of Base44's workflow — not generic programming mistakes.
Detailed Answer
The mistakes we actually see in Base44 apps
These aren't hypothetical — they're what VAS finds when it scans a Base44 app for the first time. Listed in order of how often they appear:
1. Exposed API Keys
*Why it happens:* OpenAI, Stripe, and other secret keys embedded in frontend code. Attackers can extract these and abuse your API quotas or access sensitive services.
*Fix:* Verify with a scan — catching this manually requires knowing it exists, which is the problem.
2. Database Exposure
*Why it happens:* Supabase or Firebase tables accessible without proper Row Level Security or Security Rules, allowing unauthorized data access.
*Fix:* Verify with a scan — catching this manually requires knowing it exists, which is the problem.
3. Missing Security Headers
*Why it happens:* Lack of Content-Security-Policy, Strict-Transport-Security, and other headers leaves your app vulnerable to XSS and MITM attacks.
*Fix:* Verify with a scan — catching this manually requires knowing it exists, which is the problem.
4. Weak Authentication
*Why it happens:* No password requirements, missing email verification, and lack of brute force protection on login endpoints.
*Fix:* Verify with a scan — catching this manually requires knowing it exists, which is the problem.
5. Source Map Exposure
*Why it happens:* Production source maps revealing your entire application source code, including API endpoints and business logic.
*Fix:* Verify with a scan — catching this manually requires knowing it exists, which is the problem.
Why these specifically show up in Base44 (and not as much elsewhere)
Base44's workflow optimizes for speed — idea to deployed app in minutes. The mistakes above aren't character flaws, they're the predictable output of a speed-optimized workflow that doesn't enforce security gates. The fix is treating security gates as non-negotiable, not as "I'll get to it later."

Expert Perspectives
“There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.”
“Vibe coding your way to a production codebase is clearly risky. Most of the work we do as software engineers involves evolving existing systems, where the quality and understandability of the underlying code is crucial.”

How common are these mistakes in Base44 apps — is this overstated?
Understated, if anything. The majority of Base44 apps scanned for the first time have at least one of the high-likelihood mistakes above. "Exposed API Keys" in particular is the default state of a new Base44 app before any security work. Our sample skews toward apps whose owners care enough to scan — the base rate for never-scanned Base44 apps is higher.
What are the actual consequences when these mistakes ship to production?
The consequence ladder: (a) data exposure — emails, passwords, PII, payment info readable by anyone; (b) account takeover — if auth is weak, legitimate accounts get hijacked; (c) third-party abuse — an exposed OpenAI or Stripe key gets drained of quota or money; (d) regulatory — GDPR/CCPA notification requirements trigger at ~first exposure; (e) reputational — "Base44 app data breach" is a headline that doesn't age well. Each consequence compounds the next.
How do I avoid these mistakes when building with Base44?
Three non-negotiable habits: (1) Configure Row Level Security (RLS) policies at table/collection creation — before writing any feature code. (2) Treat any paste-a-key-into-code as a bug from the first keystroke, not "I'll move it to env vars later." (3) Run a VAS scan before every production deploy — five minutes of scanning prevents hours-to-weeks of breach response. Specifically: start with exposed api keys.
