How to fix?

Upgrade actionpack to version 2.3.0, 3.1.0, 4.0.2 or higher.

Overview

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via the simple_format helper in Ruby on Rails meaning that any user provided HTML attributes will not be escaped correctly.

Note:

The simple_format helper converts user supplied text into html text which is intended to be safe for display. A change made to the implementation of this helper means that any user provided HTML attributes will not be escaped correctly. As a result of this error, applications which pass user-controlled data to be included as html attributes will be vulnerable to an XSS attack.
