Overview
Affected versions of this package are vulnerable to User Impersonation via the handling of blob: URIs, which could obscure the actual origin of a page. An attacker can deceive users regarding the true origin of web content by crafting a malicious URL. This is only exploitable if the application is running on an Android operating system.
