⚠️ A sneaky heap-based buffer overflow in Google V8 can let bad actors execute arbitrary code from a JavaScript regular expression! 😱 Think of it like a chef who trusts the recipe blindly and adds an ingredient that turns out to be a health hazard — once it's in the mix, the whole dish could be ruined! 🍽️ With this vulnerability, an attacker could potentially run any code they desire in the Chrome sandbox! This means they could manipulate or steal sensitive data without you even realizing it!

Put simply

Think of it like a chef who trusts the recipe blindly and adds an ingredient that turns out to be a health hazard — once it's in the mix, the whole dish could be ruined! 🍽️ This flaw occurs in Google V8 before version 1.1.10.14, allowing attackers to exploit the heap memory and execute malicious code through carefully crafted regular expressions in JavaScript.
