"All right, imagine I wanted to break into your app. Here's exactly what I'd do. First, I'd create an account like any normal user. I'd click around, use every feature, and learn how your app works. Nothing suspicious. Then I'd open my browser's developer tools and watch the requests your app sends to the server. I'm just looking for patterns. Let's say I notice your app loads a document with the number 742. Interesting. So I ask myself one simple question. What happens if I change that number? I replaced 742 with 743, and suddenly I'm looking at another user's private document. That's a huge problem. The server should have stopped me and said, sorry, that document doesn't belong to you. Instead, it just trusted the number I sent. I wouldn't keep doing this manually. I'd let an AI agent test hundreds or even thousands of document numbers automatically while I grab a coffee. If your app has this bug, attackers could end up accessing customer profiles, invoices, uploaded files, business documents, API keys, or other sensitive information. That information can be used for phishing, account takeovers, identity theft, fraud, blackmail, or simply leaked online to destroy your company's reputation. And the scary part? None of this requires some Hollywood hacker skills. It happens because the server forgot to check whether I was actually allowed to see that document. The fix is simple. Every request should verify who owns the data before sending it back. Never trust IDs coming from the browser. Security researchers call this an IDOR vulnerability. It's one of the most common security mistakes in web applications. Follow for more."
