Possible ReDoS vulnerability in HTTP Token authentication in Action Controller
There is a possible ReDoS vulnerability in Action Controller's
HTTP Token authentication. This vulnerability has been assigned
the CVE identifier CVE-2024-47887.

## Impact

For applications using HTTP Token authentication via
`authenticate_or_request_with_http_token` or similar, a carefully
crafted header may cause header parsing to take an unexpected amount
of time, possibly resulting in a DoS vulnerability. All users running
an affected release should either upgrade or apply the relevant
patch immediately.

Ruby 3.2 has mitigations for this problem, so Rails applications
using Ruby 3.2 or newer are unaffected. Rails 8.0.0.beta1 depends
on Ruby 3.2 or greater so is unaffected.

## Releases

The fixed releases are available at the normal locations.

## Workarounds

Users on Ruby 3.2 are unaffected by this issue.

Missing security headers in Action Pack on non-HTML responses
Permissions-Policy is Only Served on HTML Content-Type

The application configurable Permissions-Policy is only served
on responses with an HTML related Content-Type.

This has been assigned the CVE identifier CVE-2024-28103.

Versions Affected:  >= 6.1.0
Not affected:       < 6.1.0
Fixed Versions:     6.1.7.8, 7.0.8.4, and 7.1.3.4

Impact
------

Responses with a non-HTML Content-Type are not serving the configured
Permissions-Policy. There are certain non-HTML Content-Types that
would benefit from having the Permissions-Policy enforced.

Rails has a possible XSS vulnerability in its Action Pack debug exceptions
### Impact
The debug exceptions page does not properly escape exception messages.
A carefully crafted exception message could inject arbitrary HTML and JavaScript into the page, leading to XSS.
This affects applications with detailed exception pages enabled (`config.consider_all_requests_local = true`),
which is the default in development.

### Releases
The fixed releases are available at the normal locations.

Possible Content Security Policy bypass in Action Dispatch
There is a possible Cross Site Scripting (XSS) vulnerability
in the `content_security_policy` helper in Action Pack.

## Impact

Applications which set Content-Security-Policy (CSP) headers
dynamically from untrusted user input may be vulnerable to
carefully crafted inputs being able to inject new directives
into the CSP. This could lead to a bypass of the CSP and its
protection against XSS and other attacks.

## Releases

The fixed releases are available at the normal locations.

## Workarounds

Applications can avoid setting CSP headers dynamically from
untrusted input, or can validate/sanitize that input.

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.

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
