Remote Code Execution (RCE)

React Server Components are vulnerable to Remote Code Execution RCE. The vulnerability is due to the unsafe deserialization of attacker-controlled payloads sent to Server Function endpoints, which allows an attacker to execute arbitrary code without authentication...

React 19.0 / 19.1.0 / 19.1.1 / 19.2.0 Remote Code Execution

On November 29th, Lachlan Davidson reported a security vulnerability in React that allows unauthenticated remote code execution by exploiting a flaw in how React decodes payloads sent to React Server Function endpoints. Even if your app does not implement any React Server Function endpoints it ma...
