[Security] Bump rack from 2.2.2 to 2.2.3

Merged Administrator requested to merge dependabot/bundler/rack-2.2.3 into master

Created by: dependabot-preview[bot]

Bumps rack from 2.2.2 to 2.2.3. This update includes a security fix.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Percent-encoded cookies can be used to overwrite existing prefixed cookie names 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

Patched versions: ~> 2.1.4; >= 2.2.3 Unaffected versions: none
