Overview

Affected versions of this package are vulnerable to Information Exposure when it allows HTTP cookies to be set for Top Level Domains (TLDs) if the hostname is provided with a trailing dot. This issue allows arbitrary sites to set cookies that then would get sent to a different and unrelated site or domain by a malicious actor.
