What are common security mistakes in Emergent (emergent.sh) apps?
Get instant answers about your app's security.
Short Answer
The mistakes we see repeatedly in Emergent (emergent.sh) apps: exposed supabase credentials with missing rls; client-side api key leakage; unprotected api endpoints. Each one is a specific failure mode of Emergent (emergent.sh)'s workflow — not generic programming mistakes.
Detailed Answer
The mistakes we actually see in Emergent (emergent.sh) apps
These aren't hypothetical — they're what VAS finds when it scans a Emergent (emergent.sh) app for the first time. Listed in order of how often they appear:
1. Exposed Supabase Credentials with Missing RLS
*Why it happens:* Emergent apps often connect to Supabase without configuring Row Level Security, leaving tables publicly readable.
*Fix:* Verify with a scan — catching this manually requires knowing it exists, which is the problem.
2. Client-Side API Key Leakage
*Why it happens:* Third-party API keys are embedded directly in generated frontend code instead of server-side proxies.
*Fix:* Verify with a scan — catching this manually requires knowing it exists, which is the problem.
3. Unprotected API Endpoints
*Why it happens:* Backend routes generated by Emergent may lack authentication middleware.
*Fix:* Verify with a scan — catching this manually requires knowing it exists, which is the problem.
4. Insecure Default Auth Configuration
*Why it happens:* Generated auth flows may skip email verification, rate limiting, and password complexity requirements.
*Fix:* Verify with a scan — catching this manually requires knowing it exists, which is the problem.
Why these specifically show up in Emergent (emergent.sh) (and not as much elsewhere)
Emergent (emergent.sh)'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 Emergent (emergent.sh) apps — is this overstated?
Understated, if anything. The majority of Emergent (emergent.sh) apps scanned for the first time have at least one of the high-likelihood mistakes above. "Exposed Supabase Credentials with Missing RLS" in particular is the default state of a new Emergent (emergent.sh) app before any security work. Our sample skews toward apps whose owners care enough to scan — the base rate for never-scanned Emergent (emergent.sh) 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 — "Emergent (emergent.sh) 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 Emergent (emergent.sh)?
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 supabase credentials with missing rls.
