JWTs are everywhere â and so are the critical mistakes developers make with them. Algorithm confusion attacks, leaked secrets, and 'none' algorithm exploits have burned real companies. Here's how to use JWTs without shooting yourself in the foot.
You're using Math.random() to generate password reset tokens? A hacker can predict your 'random' numbers and own every account on your platform. Here's why crypto-insecure randomness is a silent killer â and how to fix it in 5 minutes.
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.
Your app isn't vulnerable to SQL injection? Great. But have you audited your 847 node_modules for prototype pollution? No? Buckle up.
You trust your logs to tell the truth. But what if attackers are writing the story? Log injection lets hackers forge entries, hide attacks, and even trigger XSS in your log viewer â and most devs never see it coming.
JWTs are everywhere, and so are the mistakes. From the infamous 'alg: none' trick to storing tokens in localStorage like it's 2013 â let's fix the most common JWT security blunders before they fix you.
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 bugs. From the infamous 'alg: none' disaster to leaking secrets in browser storage, here's how developers routinely shoot themselves in the foot with JSON Web Tokens and how to stop.
JSON Web Tokens are everywhere â and so are the footguns. From the infamous 'alg: none' exploit to weak secrets that crack in seconds, here's how JWTs go wrong and how to do them right.
JWTs are everywhere, and so are the footguns. From the infamous 'alg: none' exploit to weak secrets and missing expiry, let's walk through how developers get JWTs catastrophically wrong â and how to fix it.
JWTs look secure â they're signed! But 'alg: none', weak secrets, and missing claim validation have leaked millions of accounts. Here's how attackers break JWTs and how to make yours bulletproof.
JWTs are everywhere â auth headers, cookies, URL params. They look secure. They feel secure. But a shocking number of apps verify them wrong, sign them weakly, or don't verify them at all. Let's talk about that.
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.
JWTs are everywhere â and so are the rookie mistakes that let attackers waltz right through your auth layer. Let's fix that before someone signs their own admin token.
You've sanitized your inputs, parameterized your queries, and patched your deps. But did you check if someone can silently corrupt every object in your Node.js app? Welcome to prototype pollution.
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.
OAuth 2.0 is everywhere â GitHub login, Google auth, Spotify â but most devs implement it wrong and hand attackers the keys to the kingdom. Here's what trips people up and how to actually do it right.
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 blocked JavaScript with a strict CSP, hardened your API, and patched every XSS. Then an attacker injected 3 lines of CSS and exfiltrated your CSRF tokens anyway. Here's how CSS steals secrets â and how to stop it.
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.
You added 'Sign in with Google' in 10 minutes and felt like a genius. But did you validate the state parameter? Check the token audience? Secure your redirect URIs? Didn't think so. Let's fix that.
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.
OAuth 2.0 powers 'Login with Google' on half the internet â and half the internet is implementing it wrong. Here are the most dangerous OAuth mistakes developers make and how to fix them.
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.
