Vibe-coded app security, in plain language
Apps built with AI ship fast, and they ship the same handful of security holes again and again. These guides explain the issues that actually matter, how to tell if your app has them, and how to fix them.
Is your platform safe?
What each vibe-coding platform handles for you, and what you still have to check.
LovableIs Lovable safe? A security guide for Lovable appsLovable apps talk to Supabase from the browser. The security question is your RLS policies and what is in the bundle.BoltIs Bolt safe? A security guide for Bolt appsBolt generates the frontend AND the backend endpoints. Check that the generated API actually checks who is calling.ReplitIs Replit safe? A security guide for Replit appsReplit builds and hosts. The distinct risks are exposed Secrets/env config and a database reachable from the open internet.v0Is v0 safe? A security guide for v0 appsv0 generates Next.js apps. The distinct risks are unguarded Server Actions and Route Handlers, and NEXT_PUBLIC secret leakage.Base44Is Base44 safe? A security guide for Base44 appsBase44 runs its own backend with per-entity permissions. The distinct risk is an entity whose access rules were left open.
Vulnerabilities explained
The issues we find most often, what they mean, and how to close them.
VulnerabilityIDOR / BOLA: reading another user's dataThe single most common serious bug in vibe-coded apps: change an ID in a request and see someone else's data.VulnerabilityMissing Supabase Row Level Security (RLS)The number one reason AI-generated apps leak data: tables left readable by anyone with the public key.VulnerabilityAnonymous database accessWhen a logged-out visitor can read or write your app's data directly, bypassing the app entirely.VulnerabilitySecrets and API keys exposed in the frontendPrivate keys shipped in your JavaScript bundle, where anyone can read them and run up your bill.VulnerabilityPublic file storage bucketsUser uploads (IDs, receipts, documents) left world-readable in Supabase, Firebase, or S3 storage.VulnerabilityMissing security headersBaseline HTTP headers (CSP, HSTS, and friends) that harden your app against common attacks.VulnerabilityInsecure CORS configurationA wildcard cross-origin policy combined with credentials, letting other sites act as your users.VulnerabilityBroken access controlUsers reaching pages, actions, or admin functions they should never be allowed to use.
