CVE-2023-5654 Information

Description

The React Developer Tools extension registers a message listener with window.addEventListener(‘message’ ) 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.
