Overview

Affected versions of this package are vulnerable to Information Exposure. There is a possible information exposure / unintended method execution when using the redirect_to or polymorphic_url helper with untrusted user input. This arises because url_for supports building polymorphic URLs via an array of arguments (usually symbols and records). If a developer passes a user input array, strings can result in unwanted route helper calls.
