The Host Authorization middleware in Action Pack before 6.1.2.1, 6.0.3.5
suffers from an open redirect vulnerability. Specially crafted Host
headers in combination with certain “allowed host” formats can cause the
Host Authorization middleware in Action Pack to redirect users to a
malicious website. Impacted applications will have allowed hosts with a
leading dot. When an allowed host contains a leading dot, a specially
crafted Host header can be used to redirect to a malicious website.
