  - # Possible XSS Vulnerability in Rails::Html::SanitizerThere is a possible XSS vulnerability with certain
    configurations of Rails::Html::Sanitizer.This vulnerability has been assigned the CVE identifier
    CVE-2022-32209.Versions Affected: ALLNot affected: NONEFixed Versions: v1.4.3## ImpactA possible XSS
    vulnerability with certain configurations of Rails::Html::Sanitizer may allow an attacker to inject
    content if the application developer has overridden the sanitizer's allowed tags to allow both `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]```or```ruby# 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.##
