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: ```ruby 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 ----------- There are no feasible workarounds for this issue. Patches ------- To aid users who aren't able to upgrade immediately we have provided patches for the two supported release series. They are in git-am format and consist of a single changeset. • 7-0-translate-xss.patch - Patch for 7.0 series • 7-1-translate-xss.patch - Patch for 7.1 series Credits ------- Thanks to ooooooo_q for the patch and fix!
