⚠️ A sneaky prototype pollution vulnerability is hiding in steal.js! It all revolves around the packageName variable in npm-convert.js — worryingly simple! Think of it like a recipe book that allows anyone to add their own ingredients without permission, potentially ruining the dish. In this case, it's letting users change the behavior of your application unexpectedly! If exploited, an attacker could manipulate the application's data structures, leading to unpredictable behavior or even security risks. Imagine a chef who suddenly decides to substitute salt with sugar — the results could be disastrous!
