How to not get hacked when you’re vibe coding. This can literally sav...

Everyone's always talking about how easy it is to hack these vibe-coded apps. Probably saw it with the Tea app. Okay, so I'm going to be breaking down the three biggest vibe-coding vulnerabilities that your tool will not code with unless you specifically ask it to use these. I've done a ton of research on this. I've spent a couple hundred hours vibe-coding myself now and testing out all these tools individually. If you aren't careful with this stuff, you can cost yourself a lot of money. Here are your three biggest vulnerabilities when you're vibe-coding and then along with how to stop each one of them. The first one is no rate limiting, specifically on your API endpoint. So imagine your API endpoint is a cashier at a grocery store, for example. Without limits, one person could get in line literally 10,000 times at the same time. You have no limits on it, so you can't do anything about it. If you're using an external API, this will also make your API build go up like crazy and just crash your apps. Number two is input validation. So imagine your input field is the front door to your house. Without input validation, you're literally having it wide open with a sign that says come and rob me. This literally means that the users can send anything to your server. I once saw an example with an e-commerce site that was vibe-coded, so they didn't validate their price inputs and users were able to place negative prices on all their products. Number three, and probably the most common, is exposed API keys. So what that means is you have your API key written into your front-end code. This is essentially the same thing as writing your credit card number on your forehead. I've seen examples where people run up $30,000 on other people's API keys for no reason. They could use your API keys in their own projects. I've seen examples where API keys are literally used to crypto-mine. The easiest way to fix this is right before you start a new project vibe-coding, make a super strict PRD document. This stands for product requirements document. I've talked about this before in exactly what you'd have in every single section. The three things that you're going to want to make sure you have in your PRD document is rate limiting on every single endpoint, validate all inputs, and move all your API keys into your environment variables. And that's how you can save yourself thousands of dollars from working in states.
