Your API shouldn't blindly bind every field the client sends. Here's how mass assignment vulnerabilities let attackers promote themselves to admin by just asking nicely â and how to stop it.
SQL injection was first documented in 1998. It's 2026. It's still the #1 cause of data breaches. Let's fix that â with code examples so obvious you'll cringe at your past self.
JWTs are everywhere â auth systems, microservices, mobile apps. They're also riddled with footguns. From the 'alg: none' disaster to secret-less HS256 setups, here's what actually goes wrong and how to stop it.
Server-Side Request Forgery is the attack behind the Capital One breach, countless cloud credential leaks, and a whole lot of red-faced engineers. If your app fetches URLs, you need to read this.
JWTs are everywhere â and so are the mistakes that make them catastrophically insecure. From the 'alg:none' disaster to secret key leaks, here's what developers get wrong and how to fix it.
Your users think they're clicking 'Play Video' but they're actually approving a bank transfer. Clickjacking is sneaky, underrated, and embarrassingly easy to fix â if you know it exists.
SQL injection has been on the OWASP Top 10 since 2003 and is still wrecking databases in 2026. It's not the hackers who are embarrassing â it's us. Let's finally fix that.
JWTs are everywhere â and so are JWT vulnerabilities. From the 'alg: none' disaster to weak secrets and missing expiry checks, here's what you're almost certainly getting wrong.
Cross-Site Scripting has been killing web apps since the 90s. It's embarrassingly simple, wildly misunderstood, and your React app probably isn't as safe as you think. Let's fix that.
Server-Side Request Forgery sounds complicated, but the concept is delightfully evil: trick a server into making HTTP requests *it* shouldn't be making, then read what comes back. It took down Capital One. It lives in your URL-fetching code. Let's fix that.
SQL injection has been on the OWASP Top 10 since the list was invented. It's older than most junior devs' coding careers. And yet â it still takes down databases in 2026. Let's figure out why, and kill it for good.
You built an API, added authentication, and felt secure. Then someone changed /api/orders/1001 to /api/orders/1002 and read your customer's private data. Welcome to IDOR â the vulnerability hiding in plain sight!
You built a beautiful REST API. GET /api/users/123 returns user 123's data. What happens when an attacker tries /api/users/124? If your answer isn't 'a 403 error', we need to talk about IDOR.
Your API checks the balance, then deducts it. In those few milliseconds, a hacker fires 50 requests simultaneously. Race conditions are everywhere â in payment systems, rate limiters, and coupon codes â and they're terrifyingly easy to exploit.
Your API works perfectly â it returns exactly the data it's asked for. The problem? It'll return MY data when someone ELSE asks for it. Meet IDOR, the bug that turns user IDs into skeleton keys.
You're logged into your bank. You visit a 'funny meme' site. Suddenly your bank just transferred $500. You clicked nothing. Welcome to CSRF - where your browser betrays you completely!
You're merging objects. Parsing JSON. Building APIs. Sounds harmless, right? Prototype pollution can turn innocent-looking JavaScript into a backdoor. Here's how it works and how to stop it.
Cross-Site Request Forgery is the sneaky attack where your own users become unwitting accomplices. Learn how it works, why it's still on the OWASP Top 10, and how to stop it cold.
You change one number in a URL and suddenly you're looking at a stranger's medical records. That's IDOR â the embarrassingly simple bug that keeps breaking apps everywhere. Let's fix it.
Your logged-in users are weapons. CSRF turns their trusted sessions against them â making them change passwords, transfer money, or delete accounts without clicking a single intentional button. Here's how to stop it.
Insecure Direct Object Reference is the embarrassingly simple vulnerability hiding in almost every CRUD app. One wrong assumption and strangers are reading each other's invoices, DMs, and medical records.
You built an API, added authentication, and felt secure. Then a hacker changed one number in the URL and read every user's private data. IDOR is embarrassingly simple, devastatingly common, and entirely preventable â here's how.
Insecure Direct Object References are stupidly simple to exploit yet responsible for massive data breaches. Here's how to find them, fix them, and never ship them again.
You built a REST API, you're feeling great. Then a hacker changes /api/orders/1001 to /api/orders/1002 and reads someone else's order. Congrats, you just shipped an IDOR vulnerability â the bug that launched a thousand data breaches.
