Summary
Rails has possible XSS Vulnerability in Action Controller
Details

Possible XSS Vulnerability in Action Controller

There is a possible XSS vulnerability when using the translation helpers (translate, t, etc) in Action Controller. This vulnerability has been assigned the CVE identifier CVE-2024-26143.

Versions Affected: >= 7.0.0. Not affected: < 7.0.0 Fixed Versions: 7.1.3.1, 7.0.8.1

Impact

Applications using translation methods like translate, or t on a controller, with a key ending in "_html", a :default key which contains untrusted user input, and the resulting string is used in a view, may be susceptible to an XSS vulnerability.

For example, impacted code will look something like this:

class ArticlesController < ApplicationController
  def show  
    @message = t("message_html", default: untrusted_input)
    # The `show` template displays the contents of `@message`
  end
end

To reiterate the pre-conditions, applications must:

  • Use a translation function from a controller (i.e. not I18n.t, or t from a view)
  • Use a key that ends in _html
  • Use a default value where the default value is untrusted and unescaped input
  • Send the text to the victim (whether that's part of a template, or a render call)

All users running an affected release should either upgrade or use one of the workarounds immediately.

Releases

The fixed releases are available at the normal locations.

Workarounds
