Don't open user-supplied links with target="_blank"

This will give the target site full access to your Javascript environment through window.opener, if the target is on the same domain.

Even if the target site is on another domain, it still has some access and can for example manipulate window.location to perform a phishing attack.

You may use a rel="noopener" attribute to avoid this in modern browsers, except IE or Edge.

Does your version of Ruby on Rails still receive security updates?
Rails LTS provides security patches for old versions of Ruby on Rails (3.2 and 2.3).
