The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to an externally controlled reference to a resource in another sphere in the bundle-uri feature when cloning from a malicious remote server. A remote attacker can advertise a crafted UNC or file:// bundle URI to disclose sensitive information.
