높음 7.5CVE-2011-0449 · GHSA-4ww3-3rxj-8v6q · Published 21/02/2011 · updated 16/06/2026

Package	Affected versions	Patched versions
actionpack RubyGems	`≥ 3.0.0, < 3.0.4`	`3.0.4`
rails rubyonrails	`= 3.0.0= 3.0.1= 3.0.2= 3.0.3= 3.0.4`	No fix yet

Description

actionpack/lib/action_view/template/resolver.rb in Ruby on Rails 3.0.x before 3.0.4, when a case-insensitive filesystem is used, does not properly implement filters associated with the list of available templates, which allows remote attackers to bypass intended access restrictions via an action name that uses an unintended case for alphabetic characters.
