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. Specially crafted cookies, in combination with a specially crafted `X_FORWARDED_HOST` header can cause the regular expression engine to enter a state of catastrophic backtracking. 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.

Rails has possible Sensitive Session Information Leak in Active Storage
# Possible Sensitive Session Information Leak in Active Storage

There is a possible sensitive session information leak in Active Storage.  By
default, Active Storage sends a `Set-Cookie` header along with the user's
session cookie when serving blobs.  It also sets `Cache-Control` to public.
Certain proxies may cache the Set-Cookie, leading to an information leak.

This vulnerability has been assigned the CVE identifier CVE-2024-26144.

Versions Affected:  >= 5.2.0, < 7.1.0
Not affected:       < 5.2.0, > 7.1.0
Fixed Versions:     7.0.8.1, 6.1.7.7

Impact
------
A proxy which chooses to caches this request can cause users to share
sessions. This may include a user receiving an attacker's session or vice
versa.

This was patched in 7.1.0 but not previously identified as a security
vulnerability.

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
-----------
Upgrade to Rails 7.1.X, or configure caching proxies not to cache the
Set-Cookie headers.

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.

Exposure of information in Action Pack
Action Pack is a framework for handling and responding to web requests. Under certain circumstances response bodies will not be closed. In the event a response is *not* notified of a `close`, `ActionDispatch::Executor` will not know to reset thread local state for the next request. This can lead to data being leaked to subsequent requests. This has been fixed in Rails 7.0.2.1, 6.1.4.5, 6.0.4.5, and 5.2.6.1. Upgrading is highly recommended, but to work around this problem a middleware described in GHSA-wh98-p28r-vrc9 can be used.
