How to fix?
Upgrade ransack to version 4.0.0 or higher.
Overview
Affected versions of this package are vulnerable to Insecure Defaults. The library poses a major security risk that can likely be exploited to extract sensitive information or fully compromise the application. An attacker is be able to perform character by character brute-force of arbitrary attributes on associated database objects.
Note:
An application is potentially vulnerable if it exposes a search/filtering function which processes an unrestricted query object, usually represented by a Ruby hash constructed via the q GET parameter.
Workaround
Users who are unable to upgrade to the fixed version can restrict which associations and attributes are respected via a whitelist.
