Overview

Affected versions of this package are vulnerable to Open Redirect through the X-Forwarded-Host header. If the value of the header is prefixed with a invalid domain character (for example a /), it is always accepted as the actual host of that request. Since this host is used for all url helpers, an attacker could change generated links and redirects.
