Local Code Execution through Argument Injection via dash leading git url parameter in Gemfile

In bundler versions before 2.2.33, when working with untrusted and apparently harmless Gemfile's, it is not expected that they lead to execution of external code, unless that's explicit in the ruby code inside the Gemfile itself. However, if the Gemfile includes gem entries that use the git optio...

GHSA-QG54-694P-WGPP Regular expression denial of service vulnerability (ReDoS) in date

Date’s parsing methods including Date.parse are using Regexps internally, some of which are vulnerable against regular expression denial of service. Applications and libraries that apply such methods to untrusted input may be affected. The fix limits the input length up to 128 bytes by default...

RubyGems: Bundler's RCE with response using Marshal

A vulnerability was found in Bundler's dependency API endpoint, which uses Marshal serialization. This could allow for remote code execution if a client receives a specially crafted response. The impact is increased risk from specifying an untrusted source or man-in-the-middle attack...

RVM automatically does "bundle install" on a Gemfile specified by .versions.conf in $PWD

RVM, by default, hooks cd and automatically parses a file named .versions.conf in the directory being changed to. The intention seems to be that, if the user's $rvmautoinstallbundlerflag setting is enabled, then .versions.conf can specify a Gemfile that will automatically be fed to bundle install...

Man-in-the-Middle (MitM)

pry-rescue is vulnerable to man-in-the-middle MitM attacks. The vulnerability exists due to the use of the deprecated :rubygems option in the Gemfile, causing insecure HTTP requests to be made. A malicious user can potentially compromise the download to conduct MitM attacks...
