Описание

Happy DOM is a JavaScript implementation of a web browser without its graphical user interface. Versions prior to 20.8.9 may attach cookies from the current page origin (window.location) instead of the request target URL when fetch(..., { credentials: "include" }) is used. This can leak cookies from origin A to destination B. Version 20.8.9 fixes the issue.

A flaw was found in Happy DOM, a JavaScript implementation of a web browser without its graphical user interface. This vulnerability allows for information disclosure where cookies from the current page's origin can be inadvertently attached to network requests made to a different destination. This occurs when the fetch function is used with the credentials: "include" option, potentially leading to the leakage of sensitive user data to unintended recipients.
