CVE-2026-34226
capricorn86 happy-dom, Red Hat Ansible Automation Platform 2, Red Hat OpenShift Container Platform 4 취약점
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.
