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 allows remote attackers to bypass database-query restrictions, perform NULL checks via crafted request
`actionpack/lib/action_dispatch/http/request.rb` in Ruby on Rails before 3.0.14, 3.1.x before 3.1.6, and 3.2.x before 3.2.6 does not properly consider differences in parameter handling between the Active Record component and the Rack interface, which allows remote attackers to bypass intended database-query restrictions and perform NULL checks via a crafted request, as demonstrated by certain `['xyz', nil]` values, a related issue to CVE-2012-2660.

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 Improper Input Validation vulnerability
The `to_s` method in `actionpack/lib/action_dispatch/middleware/remote_ip.rb` in Ruby on Rails 3.0.5 does not validate the X-Forwarded-For header in requests from IP addresses on a Class C network, which might allow remote attackers to inject arbitrary text into log files or bypass intended address parsing via a crafted header.

ReDoS based DoS vulnerability in Action Dispatch
There is a possible regular expression based DoS vulnerability in Action Dispatch. This vulnerability has been assigned the CVE identifier CVE-2023-22792.

Versions Affected: >= 3.0.0 Not affected: < 3.0.0 Fixed Versions: 5.2.8.15 (Rails LTS), 6.1.7.1, 7.0.4.1
Impact

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.
Releases

The FIXED releases are available at the normal locations.
Workarounds

We recommend that all users upgrade to one of the FIXED versions. In the meantime, users can mitigate this vulnerability by using a load balancer or other device to filter out malicious X_FORWARDED_HOST headers before they reach the application.
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.

    6-1-Use-string-split-instead-of-regex-for-domain-parts.patch - Patch for 6.1 series
    7-0-Use-string-split-instead-of-regex-for-domain-parts.patch - Patch for 7.0 series

Please note that only the 7.0.Z and 6.1.Z series are supported at present, and 6.0.Z for severe vulnerabilities. Users of earlier unsupported releases are advised to upgrade as soon as possible as we cannot guarantee the continued availability of security fixes for unsupported releases.

Improper Input Validation in actionpack
Ruby on Rails 2.1 before 2.1.3 and 2.2.x before 2.2.2 does not verify tokens for requests with certain content types, which allows remote attackers to bypass cross-site request forgery (CSRF) protection for requests to applications that rely on this protection, as demonstrated using text/plain.

actionpack and activesupport vulnerable to information leaks
A certain algorithm in Ruby on Rails 2.1.0 through 2.2.2, and 2.3.x before 2.3.4, leaks information about the complexity of message-digest signature verification in the cookie store, which might allow remote attackers to forge a digest via multiple attempts.

Possible ReDoS vulnerability in query parameter filtering in Action Dispatch
There is a possible ReDoS vulnerability in the query parameter filtering routines of Action Dispatch. This vulnerability has been assigned the CVE identifier CVE-2024-41128.

Impact
------

Carefully crafted query parameters can cause query parameter filtering 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.

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.
