How to fix?
Upgrade rails_multisite to version 4.0.0 or higher.
Overview
rails_multisite is a gem for multi-db support for Rails applications.
Affected versions of this package are vulnerable to Improper Input Validation. Secure/signed cookies share secrets between sites in a multi-site application.
Impact
This vulnerability impacts any Rails applications using rails_multisite alongside Rails' signed/encrypted cookies. Depending on how the application makes use of these cookies, it may be possible for an attacker to re-use cookies on different 'sites' within a multi-site Rails application.
