Ruby on Rails 'number_to_currency' Helper Cross Site Scripting Vulnerability

Ruby on Rails is prone to a cross-site scripting vulnerability because it fails to sufficiently sanitize user-supplied input.

An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.

This vulnerability is fixed in Ruby on Rails 4.0.2 and 3.2.16.
