Someone just pwned V8 — and it's not what you'd expect

Himanshu Anand spent a free afternoon playing with V8, Google's open-source JavaScript engine that runs Chrome and Node. He found a way to break it. The writeup is raw — no corporate polish, just a dev working through what went wrong and why. V8 is the engine behind basically everything you build with JavaScript. If you can break V8, you can break a lot of things people think are safe.

The post doesn't sell the exploit as a weapon. It reads like a dev log: what he tried, what worked, what didn't. That's the honest part. The kind of thing that circulates quietly in security circles and shows up in boardroom briefings later when someone's asking why their Node stack got hit.

Why this matters for us: a lot of the apps running in our neighborhoods — payment processors, delivery tools, side hustles — are built on Node. When the engine underneath gets pwned, the people who know about it move fast, and the rest of us just watch our apps break.
