Overview

Affected versions of this package are vulnerable to User Interface (UI) Misrepresentation of Critical Information due to the address bar truncating the display of URLs from the end rather than prioritizing the origin. An attacker can mislead users about the true origin of a website by crafting long URLs that obscure the actual domain.
