actionpack Improper Input Validation vulnerability
The template selection functionality in `actionpack/lib/action_view/template/resolver.rb` in Ruby on Rails 3.0.x before 3.0.10 and 3.1.x before 3.1.0.rc6 does not properly handle glob characters, which allows remote attackers to render arbitrary views via a crafted URL, related to a "filter skipping vulnerability."

actionpack Improper Authentication vulnerability
The `decode_credentials` method in `actionpack/lib/action_controller/metal/http_authentication.rb` in Ruby on Rails before 3.0.16, 3.1.x before 3.1.7, and 3.2.x before 3.2.7 converts Digest Authentication strings to symbols, which allows remote attackers to cause a denial of service by leveraging access to an application that uses a `with_http_digest` helper method, as demonstrated by the `authenticate_or_request_with_http_digest` method.

actionpack allows bypass of database-query restrictions
`actionpack/lib/action_dispatch/http/request.rb` in Ruby on Rails before 3.2.16 and 4.x before 4.0.2 does not properly consider differences in parameter handling between the Active Record component and the JSON implementation, which allows remote attackers to bypass intended database-query restrictions and perform NULL checks or trigger missing WHERE clauses via a crafted request that leverages (1) third-party Rack middleware or (2) custom Rack middleware.  NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-0155.

actionpack Cross-site Scripting vulnerability
Cross-site scripting (XSS) vulnerability in `actionpack/lib/action_view/helpers/form_tag_helper.rb` in Ruby on Rails 3.x before 3.0.17, 3.1.x before 3.1.8, and 3.2.x before 3.2.8 allows remote attackers to inject arbitrary web script or HTML via the `prompt` field to the `select_tag` helper.

Untrusted users can run pending migrations in production in Rails
There is a vulnerability in versions of Rails prior to 6.0.3.2 that allowed an untrusted user to run any pending migrations on a Rails app running in production.

This vulnerability has been assigned the CVE identifier CVE-2020-8185.

Versions Affected:  6.0.0 < rails < 6.0.3.2
Not affected:       Applications with `config.action_dispatch.show_exceptions = false` (this is not a default setting in production)
Fixed Versions:     rails >= 6.0.3.2

Impact
------

Using this issue, an attacker would be able to execute any migrations that are pending for a Rails app running in production mode. It is important to note that an attacker is limited to running migrations the application developer has already defined in their application and ones that have not already run.

Workarounds
-----------

Until such time as the patch can be applied, application developers should disable the ActionDispatch middleware in their production environment via a line such as this one in their config/environment/production.rb:

`config.middleware.delete ActionDispatch::ActionableExceptions`

Cross-site Scripting vulnerability in i18n translations helper method
Cross-site scripting (XSS) vulnerability in the i18n translations helper method in Ruby on Rails 3.0.x before 3.0.11 and 3.1.x before 3.1.2, and the rails_xss plugin in Ruby on Rails 2.3.x, allows remote attackers to inject arbitrary web script or HTML via vectors related to a translations string whose name ends with an "html" substring.

actionpack vulnerable to Cross-site Scripting
Cross-site scripting (XSS) vulnerability in `actionpack/lib/action_view/helpers/translation_helper.rb` in the internationalization component in Ruby on Rails 3.x before 3.2.16 and 4.x before 4.0.2 allows remote attackers to inject arbitrary web script or HTML via a crafted string that triggers generation of a fallback string by the i18n gem.

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.
