Descriptions

The React Developer Tools extension registers a message listener with window.addEventListener('message', <listener>) in a content script that is accessible to any webpage that is active in the browser. Within the listener is code that requests a URL derived from the received message via fetch(). The URL is not validated or sanitised before it is fetched, thus allowing a malicious web page to arbitrarily fetch URL’s via the victim's browser.

La extensión React Developer Tools registra un detector de mensajes con window.addEventListener('message', ) en un script de contenido al que se puede acceder desde cualquier página web que esté activa en el navegador. Dentro del oyente hay un código que solicita una URL derivada del mensaje recibido mediante fetch(). La URL no se valida ni se sanitiza antes de recuperarla, lo que permite que una página web maliciosa obtenga URL de forma arbitraria a través del navegador de la víctima.
