There is a possible open redirect vulnerability in the Host Authorization
middleware in Action Pack.
Specially crafted “X-Forwarded-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. For example,
configuration files that look like this:
config.hosts << '.EXAMPLE.com'
When an allowed host contains a leading dot, a specially crafted Host header
can be used to redirect to a malicious website.
This vulnerability is similar to CVE-2021-22881 and CVE-2021-22942.
The fixed releases are available at the normal locations.
To aid users who aren’t able to upgrade immediately we have provided patches for
the two supported release series. They are in git-am format and consist of a
single changeset.
Please note that only the 6.1.Z, 6.0.Z, and 5.2.Z series are supported at
present. Users of earlier unsupported releases are advised to upgrade as soon
as possible as we cannot guarantee the continued availability of security
fixes for unsupported releases.
