Why Security Matters for Vibe Coders

Your Learning Path (Step 2 of 4)

The Speed vs Security Tradeoff

Vibe coding is incredibly fast. What used to take weeks now takes hours. You can go from idea to working app in a single afternoon. This speed is revolutionary, but it comes with a hidden cost.

When you ask AI to build a feature, it optimizes for one thing: making it work. Security is almost never the priority. The AI doesn't think about:

• Who might try to abuse this feature
• What data needs protection
• How attackers commonly exploit similar systems
• What happens if something goes wrong

This isn't a flaw in the AI. It's doing exactly what you asked. But it means security becomes entirely your responsibility.

Real Risks for Vibe-Coded Apps

These aren't theoretical concerns. Here's what actually happens when security is ignored:

Exposed API Keys

Your OpenAI, Stripe, or AWS keys get pushed to GitHub or embedded in frontend code. Attackers find them within minutes using automated scanners. Result: unexpected bills that can reach thousands of dollars before you notice.

Missing Database Security

Supabase and Firebase apps without Row Level Security (RLS) expose all user data to anyone who knows the database URL. One API call can download your entire user table, including emails, passwords, and personal information.

Unprotected Endpoints

API routes that should require authentication are left open. Attackers can delete data, modify records, or access admin functionality without logging in.

Credential Stuffing

Without rate limiting, attackers can try thousands of stolen username/password combinations against your login page. If any of your users reuse passwords, their accounts get compromised.

The True Cost of Security Incidents

Why Vibe-Coded Apps Are More Vulnerable

1. Speed Encourages Shortcuts

When you can build in hours, adding security feels like it's slowing you down. The temptation to "add security later" is strong. But later rarely comes, and by then you have real users at risk.

2. AI Doesn't Think Like an Attacker

Traditional developers learn security through experience. They've seen what goes wrong. AI tools generate code based on patterns, not security awareness.

3. Founders Often Lack Technical Background

Many vibe coders are domain experts, designers, or entrepreneurs, not security specialists. They don't know what to look for because they've never needed to before.

4. Security Issues Are Invisible

A broken feature is obvious. Users complain. But a security hole? It works perfectly until someone exploits it. You won't know your API keys are exposed until the bill arrives.

Security Doesn't Have to Be Hard

Here's the good news: basic security is not complicated. Most vibe-coded apps can be significantly more secure with just a few changes:

1. Run a security scan to identify obvious issues
2. Move secrets to environment variables (10 minutes)
3. Enable database RLS if using Supabase or Firebase (30 minutes)
4. Add authentication checks to sensitive API routes (varies)
5. Set up HTTPS (usually automatic with Vercel/Netlify)

These basic steps prevent the vast majority of attacks targeting vibe-coded apps.

Your Responsibility as a Builder

When users sign up for your app, they trust you with their data. This is true whether you're a Fortune 500 company or a solo founder who built everything with Cursor last weekend.

The tools you use don't change your obligations:

• If you collect email addresses, you need to protect them
• If you handle passwords, you need to hash them properly
• If you process payments, you need to secure that flow
• If you store personal data, you need to prevent unauthorized access

Vibe coding democratizes building. It doesn't democratize the consequences of building insecurely.
