Impacted is confidentiality, integrity, and availability. CVE summarizes:

The ActiveSupport::XmlMini_JDOM backend in lib/active_support/xml_mini/jdom.rb in the Active Support component in Ruby on Rails 3.0.x and 3.1.x before 3.1.12 and 3.2.x before 3.2.13, when JRuby is used, does not properly restrict the capabilities of the XML parser, which allows remote attackers to read arbitrary files or cause a denial of service (resource consumption) via vectors involving (1) an external DTD or (2) an external entity declaration in conjunction with an entity reference.

The weakness was disclosed 10/22/2013 by Ben Murphy as APPLE-SA-2013-10-22-5 as confirmed mailinglist post (Apple Security Mailinglist). The advisory is shared for download at lists.apple.com. The mailinglist post contains:

Multiple issues existed in Ruby on Rails, the most serious of which may lead to cross site scripting. These issues were addressed by updating the Rails implementation used by Profile Manager to version 2.3.18.
