CVE-2013-6416
Cross-site scripting (XSS) vulnerability in the simple_format helper in actionpack/lib/action_view/helpers/text_helper.rb in Ruby on Rails 4.x before 4.0.2 allows remote attackers to inject arbitrary web script or HTML via a crafted HTML attribute.
Does this matter?
Lower severity and a low EPSS score (1.96%). Track it; it rarely justifies an emergency change on its own.
