🚨 Your current dependencies have known security vulnerabilities 🚨
This dependency update fixes known security vulnerabilities. Please see the details below and assess their impact carefully. We recommend to merge and deploy this as soon as possible!
Here is everything you need to know about this upgrade. Please take a good look at what changed and the test results before merging this pull request.
There is a possible regular expression based DoS vulnerability in Action
Dispatch. This vulnerability has been assigned the CVE identifier CVE-2023-22792.
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.
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.
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.
Versions Affected: All
Not affected: None
Fixed Versions: 6.1.7.1, 7.0.4.1
Impact
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.
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 If-None-Match headers before they reach
the application.
Users on Ruby 3.2.0 or greater are not affected by this vulnerability.
There is a possible open redirect when using the redirect_to helper with
untrusted user input.
Vulnerable code will look like this:
redirect_to(params[:some_param])
Rails 7.0 introduced protection against open redirects from calling
redirect_to with untrusted user input. In prior versions the developer was
fully responsible for only providing trusted input. However the check
introduced could be bypassed by a carefully crafted URL.
All users running an affected release should either upgrade or use one of
the workarounds immediately.
CSP headers were only sent along with responses that Rails considered as
"HTML" responses. This left API requests without CSP headers, which could
possibly expose users to XSS attacks.
Releases
The FIXED releases are available at the normal locations.
Under certain circumstances response bodies will not be closed, for example a
bug in a webserver (puma/puma#2812) or a bug in a Rack
middleware. 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,
especially when interacting with ActiveSupport::CurrentAttributes.
Upgrading to the FIXED versions of Rails will ensure mitigation if this issue
even in the context of a buggy webserver or middleware implementation.
Patches
This has been fixed in Rails 7.0.2.2, 6.1.4.6, 6.0.4.6, and 5.2.6.2.
Workarounds
Upgrading is highly recommended, but to work around this problem the following
middleware can be used:
class GuardedExecutor < ActionDispatch::Executor
def call(env)
ensure_completed!
super
end
private
def ensure_completed!
@executor.new.complete! if @executor.active?
end
end
# Ensure the guard is inserted before ActionDispatch::Executor
Rails.application.configure do
config.middleware.swap ActionDispatch::Executor, GuardedExecutor, executor
end
There is a possible XSS vulnerability in Action View tag helpers. Passing
untrusted input as hash keys can lead to a possible XSS vulnerability. This
vulnerability has been assigned the CVE identifier CVE-2022-27777.
Versions Affected: ALL
Not affected: NONE
Fixed Versions: 7.0.2.4, 6.1.5.1, 6.0.4.8, 5.2.7.1
Impact
If untrusted data is passed as the hash key for tag attributes, there is a
possibility that the untrusted data may not be properly escaped which can
lead to an XSS vulnerability.
There is a potential denial of service vulnerability present in
ActiveRecord’s PostgreSQL adapter.
This has been assigned the CVE identifier CVE-2022-44566.
Versions Affected: All.
Not affected: None.
Fixed Versions: 7.0.4.1, 6.1.7.1
Impact
In ActiveRecord <7.0.4.1 and <6.1.7.1, when a value outside the range for a
64bit signed integer is provided to the PostgreSQL connection adapter, it
will treat the target column type as numeric. Comparing integer values
against numeric values can result in a slow sequential scan resulting in
potential Denial of Service.
Workarounds
Ensure that user supplied input which is provided to ActiveRecord clauses do
not contain integers wider than a signed 64bit representation or floats.
There is a possible vulnerability in ActiveRecord related to the
sanitization of comments. This vulnerability has been assigned the CVE
identifier CVE-2023-22794.
Previously the implementation of escaping for comments was insufficient for
If malicious user input is passed to either the annotate query method, the
optimizer_hints query method, or through the QueryLogs interface which
automatically adds annotations, it may be sent to the database with
insufficient sanitization and be able to inject SQL outside of the comment.
In most cases these interfaces won’t be used with user input and users
should avoid doing so.
There is a possible escalation to RCE when using YAML serialized columns in
Active Record. This vulnerability has been assigned the CVE identifier CVE-2022-32224.
Versions Affected: All.
Not affected: None
Fixed Versions: 7.0.3.1, 6.1.6.1, 6.0.5.1, 5.2.8.1
Impact
When serialized columns that use YAML (the default) are deserialized, Rails
uses YAML.unsafe_load to convert the YAML data in to Ruby objects. If an
attacker can manipulate data in the database (via means like SQL injection),
then it may be possible for the attacker to escalate to an RCE.
Impacted Active Record models will look something like this:
classUser < ApplicationRecordserialize:options# Vulnerable: Uses YAML for serializationserialize:values,Array# Vulnerable: Uses YAML for serializationserialize:values,JSON# Not vulnerableend
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.
The released versions change the default YAML deserializer to use YAML.safe_load, which prevents deserialization of possibly dangerous
objects. This may introduce backwards compatibility issues with existing
data.
In order to cope with that situation, the released version also contains two
new Active Record configuration options. The configuration options are as
follows:
config.active_storage.use_yaml_unsafe_load
When set to true, this configuration option tells Rails to use the old
"unsafe" YAML loading strategy, maintaining the existing behavior but leaving
the possible escalation vulnerability in place. Setting this option to true
is not recommended, but can aid in upgrading.
The "safe YAML" loading method does not allow all classes to be deserialized
by default. This option allows you to specify classes deemed "safe" in your
application. For example, if your application uses Symbol and Time in
serialized data, you can add Symbol and Time to the allowed list as follows:
There is a possible code injection vulnerability in the Active Storage module
of Rails. This vulnerability has been assigned the CVE identifier
CVE-2022-21831.
There is a possible code injection vulnerability in the Active Storage module
of Rails. This vulnerability impacts applications that use Active Storage
with the image_processing processing in addition to the mini_magick back end
for image_processing.
Vulnerable code will look something similar to this:
Where the transformation method or its arguments are untrusted arbitrary
input.
All users running an affected release should either upgrade or use one of the
workarounds immediately.
Workarounds
To work around this issue, applications should implement a strict allow-list
on accepted transformation methods or arguments. Additionally, a strict image
magick security policy will help mitigate this issue.
There is a possible regular expression based DoS vulnerability in Active
Support. This vulnerability has been assigned the CVE identifier CVE-2023-22796.
Versions Affected: All
Not affected: None
Fixed Versions: 6.1.7.1, 7.0.4.1
Impact
A specially crafted string passed to the underscore method 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.
This affects String#underscore, ActiveSupport::Inflector.underscore,
String#titleize, and any other methods using these.
All users running an affected release should either upgrade or use one of the
workarounds immediately.
Workarounds
There are no feasible workarounds for this issue.
Users on Ruby 3.2.0 or greater may be able to reduce the impact by
configuring Regexp.timeout.
