CVE-2021-22881 Open this link in a new tabAmendment
This was deemed not a vulnerability.
Overview
rails is an opensource MVC web framework.
Affected versions of this package are vulnerable to Open Redirect. Specially crafted Host headers in combination with certain allowed host formats can cause the Host Authorization middleware in ActionPack to redirect users to a malicious website. When an allowed host contains a leading dot, a specially crafted Host header can be used to redirect to a malicious website.
NOTE: This advisory was altered as the actual vulnerability is in the actionpack module, which is a dependency of rails.
