Overview

Affected versions of this package are vulnerable to Inappropriate Encoding for Output Context due to the URL parser which wrongly accepts percent-encoded URL separators like / when decoding the hostname part of a URL, making it a different URL using the wrong hostname when it is later retrieved.
