Imagine clicking a random link and accidentally transferring your bank balance to a hacker. That's CSRF in a nutshell — and your app is probably vulnerable right now. Let's fix that.
Your browser is loyal — it sends your cookies everywhere you go. Hackers love that. CSRF attacks exploit this blind trust to make your browser submit requests you never intended. Here's how it works and how to stop it.
What happens when you send the same parameter twice in a URL? Chaos. Beautiful, exploitable chaos. Let me show you how attackers abuse duplicate parameters to bypass your security checks.
Cross-Site Request Forgery sounds complicated, but it's basically a hacker tricking your browser into doing bad things while you're logged in. Here's how it works, why it's sneaky, and how to stop it cold.
Insecure Direct Object References are embarrassingly easy to exploit and shockingly common in production APIs. One wrong endpoint and any user can read—or delete—everyone else's data. Let's fix that.
That innocent ?redirect_to= parameter in your URL? Hackers are using it to send your users straight to malware sites — and your users will never suspect a thing.
Your users are logged in, authenticated, and trusting your app with their data. Now imagine a malicious website quietly making requests on their behalf — transferring money, changing passwords, deleting accounts — without them ever clicking anything suspicious. Welcome to CSRF, the sneaky impersonation attack that's been around forever and still bites developers daily.
You called exec() to run a quick ping. The attacker called it to run rm -rf /. Command injection turns your server into an open terminal — here's exactly how it happens and how to stop it.
Meet \\\r\\\n — the two most underrated troublemakers in web security. CRLF injection can split your HTTP responses, inject fake headers, and even pull off XSS. Spoiler: your framework probably saves you, but only if you know when to let it.
You built a beautiful REST API, authenticated every endpoint, and even wrote tests. But did you check whether user A can read user B's data just by changing a number in the URL? That's IDOR — the vulnerability that's embarrassingly easy to exploit and embarrassingly easy to miss.
Changing ?user_id=123 to ?user_id=124 and suddenly seeing someone else's medical records. IDOR is OWASP's #1 vulnerability and it's embarrassingly simple — yet developers ship it every day. Let's fix that.
You're logged into your bank. You visit a sketchy site. Your browser quietly transfers $10,000 without you knowing. That's CSRF — and your app might be wide open to it right now.
You built a beautiful API, deployed it proudly, and then someone just changed ?user_id=123 to ?user_id=124 and read your entire user database. IDOR is the vulnerability hiding in plain sight — and it's embarrassingly easy to miss.
You built a cute profile picture uploader. A hacker uploaded a PHP shell and now owns your server. Let's make sure that never happens to you.
You've probably shipped an IDOR vulnerability without knowing it. Insecure Direct Object Reference is embarrassingly simple, insanely common, and responsible for some of the biggest data breaches of the decade. Let's fix that.
Your app blindly trusts the Host header in every request — and attackers love that. Here's how password reset link poisoning works, why it's so sneaky, and how to stop it before a hacker finds it first.
Insecure Direct Object References — the bug so simple it's embarrassing, yet so common it's in the OWASP Top 10. I once found my own app serving every user's private invoices to anyone who guessed a URL. Let me save you that call with your CEO.
You built a perfect user registration endpoint. Too bad anyone can send role=admin in the body and become a superuser. Mass assignment is the vulnerability your ORM is hiding from you.
Your logged-in user visits an innocent-looking page. Suddenly, they've just transferred money, changed their email, or deleted their account — and they have absolutely no idea. Welcome to CSRF, the sneakiest free labor a hacker ever got.
Imagine someone tricking you into wiring money just by getting you to visit a website. That's CSRF - and it's been silently attacking users for decades. Let's break it down.
Change one number in a URL and suddenly you're reading someone else's medical records. IDOR is embarrassingly simple, devastatingly common, and pays out big on bug bounties. Let's break it down.
That innocent shell_exec() call? It's basically handing a stranger your server's keyboard. Let's talk about OS command injection - the vulnerability that turns your app into a personal hacker playground.
You built an API. You tested it. Everything works. Then a hacker changes ?user_id=123 to ?user_id=124 and downloads someone else's data. Welcome to IDOR — the embarrassingly simple bug that haunts production apps worldwide.
You didn't build a phishing page. But an attacker is using your trusted domain to redirect victims to one. Open redirect — the vulnerability that makes your good reputation work against you.
Changing ?invoice_id=1001 to ?invoice_id=1002 and suddenly seeing someone else's bank details? That's IDOR — the embarrassingly simple vulnerability that's OWASP's #1 security risk and still breaks production apps every single day.
You built an API. You added authentication. You feel safe. But one tiny URL like /api/orders/1337 could hand all your users' data to a random stranger. Welcome to IDOR - the embarrassingly simple bug that breaks into Fortune 500 companies daily.
