Outdated coding methods to avoid when vibe coding

AI gave you working code.

But did it give you secure code?

Outdated Coding Methods to Avoid (When Vibe Coding) is a sharp, visual guide that helps you catch the dangerous defaults AI still suggests—before they quietly wreck your app, compromise user data, or create costly security gaps.

Why this guide matters

AI tools are fast—but they’re trained on forums and legacy codebases where insecure practices are still the norm.

Why you need this guide

AI tools are fast—but they’re trained on forums and outdated codebases where insecure practices are still the norm.

If you’ve ever seen AI confidently suggest:

• localStorage for session tokens
• MD5 or SHA1 for password hashing
• API keys hardcoded directly into app.py
• eval() used to “dynamically run logic”
• No rate limiting on login forms
• HTTP instead of HTTPS
• Or worse: AI just hallucinates something that looks legit—
  but would expose user data or break your auth flow...

...then you already know the risk.

The problem isn’t just what AI suggests—
It’s what it forgets to warn you about.

This guide shows you how to catch these issues, fix them fast, and prompt your AI to generate safer, smarter code from the start.

What’s inside:

Every chapter follows the same trusted format:

• A short, no-jargon intro that explains what’s risky and why
• One real-world example of what can go wrong
• A visual AVOID / USE INSTEAD table
• AI prompt templates to guide your assistant toward modern best practices
• A glossary that simplifies confusing terms (right at the end of each chapter)

Learn from what actually happens

In 2024, Rabbit Inc. accidentally shipped source code with live API keys—including access to voice and email services.
The result?
Spammers hijacked their services within hours.

This guide breaks down exactly what they did wrong—and how you can avoid doing the same, even when moving fast with AI.
