React Hacked: How One Request Can Take Over Your Server.

Description

Stop what you are doing and check your package.json. 🛑 A new critical vulnerability, dubbed "React2Shell" (CVE-2025-55182), has been discovered in React Server Components, and it is being actively exploited. This is a CVSS 10.0 severity flaw that allows attackers to achieve Remote Code Execution (RCE) on your server with a single HTTP request—no authentication required. If you are using Next.js or React 19, your application is likely at risk. In this video, I break down: 💀 The Exploit: How the "Flight" protocol deserialization flaw works. 🔍 The Impact: Why this is being called the "Log4J of JavaScript." 🛡️ The Fix: Exactly which versions of Next.js and React you need to upgrade to immediately. 👨‍💻 Demo: A look at how the attack vector works (safely) so you understand the risk. Don't leave your servers open to a shell. Patch now. Timestamps: 0:00 - The React2Shell Crisis 1:45 - What is CVE-2025-55182?
