Rails has possible XSS Vulnerability in Action Controller
# 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.

ReDoS based DoS vulnerability in Action Dispatch
There is a possible regular expression based DoS vulnerability in Action Dispatch related to the If-None-Match header. This vulnerability has been assigned the CVE identifier CVE-2023-22795. A specially crafted HTTP `If-None-Match` header can cause the regular expression engine to enter a state of catastrophic backtracking, when on a version of Ruby below 3.2.0. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability All users running an affected release should either upgrade or use one of the workarounds immediately.
