A security researcher has found a new flaw in Microsoft’s Edge browser that allows attackers to access content from other domains you have open in your browser, or to act as you on those domains. For instance, if you click a specially crafted link, the attacker could tweet as you, assuming you have Twitter opened in Edge as well. This is called a universal cross-site scripting (UXSS) or same-origin policy bypass vulnerability. Watch the video to learn more about these flaws and what you can do if you use the Edge browser.
