There was this moment—about two years back—when I was debugging what should’ve been a harmless bug. Our Node.js app kept returning odd values in a user permissions object. Took me a bit, but the root cause chilled me. Prototype pollution.…
We see a lot of folks jump straight into using the fs module for file work in Node.js, but that’s where trouble can sneak in if you’re not careful. Reading and writing files isn’t just about picking the right method—it’s…
We’ve all had that moment—some weird request hits our API, and everything just stops working. Maybe it was a missing field. Maybe it was a string where we expected a number. Or worse, a script tag slipped into a field…
We see command injection slip into Node.js projects more often than folks realize, especially when the child_process module gets involved. It’s easy to overlook, but letting user input touch shell commands—especially with exec—can give attackers a straight shot at your…
We see Express.js everywhere—fast, flexible, and powering a ton of web apps and APIs. But with that popularity comes a steady stream of attackers looking for weak spots. In our training bootcamp, we push the idea that securing Express.js isn’t…
We see a lot of Node.js apps go live with good intentions but shaky defenses, and it’s easy to forget that just writing code isn’t enough. Threats hit from every angle—data leaks, broken authentication, risky packages. That’s why we built…
Secure coding in Node.js starts with recognizing that every choice in development can open or close the door to attackers. From the dependencies you install to how you manage user sessions, each decision shapes your application’s security. Node.js has unique…
We see clickjacking pop up more often than most folks expect—a user thinks they’re clicking a harmless button, but behind the scenes, they’re triggering something dangerous because your site’s been tucked away inside a hidden frame. It’s not just a…
We’ve all had that moment—opening up the browser, watching our web app flicker to life, and wondering, “Is this safe?” Not just from broken code or missed logic, but from real, lurking threats. We’re talking about scripts sneaking in, maybe…
We train developers every day to spot the weak points in their JavaScript API calls, especially when using fetch or axios. We’ve seen how easy it is for mistakes to creep in—tokens exposed, bad input slipping through, or sensitive data…
