🚨 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 update. Please take a good look at what changed and the test results before merging this pull request.
It is possible to forge a secure or host-only cookie prefix in Rack using
an arbitrary cookie write by using URL encoding (percent-encoding) on the
name of the cookie. This could result in an application that is dependent on
this prefix to determine if a cookie is safe to process being manipulated
into processing an insecure or cross-origin request.
This vulnerability has been assigned the CVE identifier CVE-2020-8184.
Versions Affected: rack < 2.2.3, rack < 2.1.4
Not affected: Applications which do not rely on __Host- and __Secure- prefixes to determine if a cookie is safe to process
Fixed Versions: rack >= 2.2.3, rack >= 2.1.4
Impact
An attacker may be able to trick a vulnerable application into processing an
insecure (non-SSL) or cross-origin request if they can gain the ability to write
arbitrary cookies that are sent to the application.
Workarounds
If your application is impacted but you cannot upgrade to the released versions or apply
the provided patch, this issue can be temporarily addressed by adding the following workaround:
module Rack
module Utils
module_function def parse_cookies_header(header)
return {} unless header
header.split(/[;] */n).each_with_object({}) do |cookie, cookies|
next if cookie.empty?
key, value = cookie.split('=', 2)
cookies[key] = (unescape(value) rescue value) unless cookies.key?(key)
end
end
end
end

There was a possible directory traversal vulnerability in the Rack::Directory app
that is bundled with Rack.
Versions Affected: rack < 2.2.0
Not affected: Applications that do not use Rack::Directory.
Fixed Versions: 2.1.3, >= 2.2.0
Impact
If certain directories exist in a director that is managed by Rack::Directory, an attacker could, using this vulnerability, read the
contents of files on the server that were outside of the root specified in the
Rack::Directory initializer.
Workarounds
Until such time as the patch is applied or their Rack version is upgraded,
we recommend that developers do not use Rack::Directory in their
applications.

There's a possible information leak / session hijack vulnerability in Rack.
Attackers may be able to find and hijack sessions by using timing attacks
targeting the session id. Session ids are usually stored and indexed in a
database that uses some kind of scheme for speeding up lookups of that
session id. By carefully measuring the amount of time it takes to look up
a session, an attacker may be able to find a valid session id and hijack
the session.
The session id itself may be generated randomly, but the way the session is
indexed by the backing store does not use a secure comparison.
Impact:
The session id stored in a cookie is the same id that is used when querying
the backing session storage engine. Most storage mechanisms (for example a
database) use some sort of indexing in order to speed up the lookup of that
id. By carefully timing requests and session lookup failures, an attacker
may be able to perform a timing attack to determine an existing session id
and hijack that session.
Response.[] and MockResponse.[] for creating instances using status, headers, and body. (@ioquatix)
Convenient cache and content type methods for Rack::Response. (#1555, @ioquatix)
Changed
Request#params no longer rescues EOFError. (@jeremyevans)
Directory uses a streaming approach, significantly improving time to first byte for large directories. (@jeremyevans)
Directory no longer includes a Parent directory link in the root directory index. (@jeremyevans)
QueryParser#parse_nested_query uses original backtrace when reraising exception with new class. (@jeremyevans)
ConditionalGet follows RFC 7232 precedence if both If-None-Match and If-Modified-Since headers are provided. (@jeremyevans)
.ru files supports the frozen-string-literal magic comment. (@eregon)
Rely on autoload to load constants instead of requiring internal files, make sure to require 'rack' and not just 'rack/...'. (@jeremyevans)
Etag will continue sending ETag even if the response should not be cached. (@henm)
Request#host_with_port no longer includes a colon for a missing or empty port. (@AlexWayfer)
All handlers uses keywords arguments instead of an options hash argument. (@ioquatix)
Files handling of range requests no longer return a body that supports to_path, to ensure range requests are handled correctly. (@jeremyevans)
Multipart::Generator only includes Content-Length for files with paths, and Content-Dispositionfilename if the UploadedFile instance has one. (@jeremyevans)
Request#ssl? is true for the wss scheme (secure websockets). (@jeremyevans)
Rack::HeaderHash is memoized by default. (#1549, @ioquatix)
Rework host/hostname/authority implementation in Rack::Request. #host and #host_with_port have been changed to correctly return IPv6 addresses formatted with square brackets, as defined by RFC3986. (#1561, @ioquatix)
Rack::Builder parsing options on first #\ line is deprecated. (#1574, @ioquatix)
Removed
Directory#path as it was not used and always returned nil. (@jeremyevans)
BodyProxy#each as it was only needed to work around a bug in Ruby <1.9.3. (@jeremyevans)
URLMap::INFINITY and URLMap::NEGATIVE_INFINITY, in favor of Float::INFINITY. (@ch1c0t)
Deprecation of Rack::File. It will be deprecated again in rack 2.2 or 3.0. (@rafaelfranca)
Support for Ruby 2.2 as it is well past EOL. (@ioquatix)
Remove Rack::Files#response_body as the implementation was broken. (#1153, @ioquatix)
Remove SERVER_ADDR which was never part of the original SPEC. (#1573, @ioquatix)
