select
and style
elements.Code is only impacted if allowed tags are being overridden. This may be done via application configuration:ruby# In config/application.rbconfig.action_view.sanitized_allowed_tags = ["select", "style"]
see https://guides.rubyonrails.org/configuring.html#configuring-action-viewOr it may be done with a :tags
option to the Action View helper sanitize
:<%= sanitize @comment.body, tags: ["select", "style"] %>
see https://api.rubyonrails.org/classes/ActionView/Helpers/SanitizeHelper.html#method-i-sanitizeOr it may be done with Rails::Html::SafeListSanitizer directly:ruby# class-level optionRails::Html::SafeListSanitizer.allowed_tags = ["select", "style"]
orruby# instance-level optionRails::Html::SafeListSanitizer.new.sanitize(@article.body, tags: ["select", "style"])
All users overriding the allowed tags by any of the above mechanisms to include both “select” and “style” should either upgrade or use one of the workarounds immediately.## ReleasesThe FIXED releases are available at the normal locations.## WorkaroundsRemove either select
or style
from the overridden allowed tags.## CreditsThis vulnerability was responsibly reported by windshock.OS | Version | Architecture | Package | Version | Filename |
