Overview

Affected versions of this package are vulnerable to User Interface (UI) Misrepresentation of Critical Information via the Android custom tab UI, which displayed only the "site" rather than the full hostname. An attacker can mislead users about the true origin of web content by hosting user-supplied content on a subdomain, potentially causing users to believe the content is from a different subdomain.
