ArchLinux: 202106-14: ruby-bundler: insufficient validation
Summary
Bundler 1.16.0 through 2.2.9 and 2.2.11 through 2.2.17 sometimes chooses a dependency source based on the highest gem version number, which means that a rogue gem found at a public source may be chosen, even if the intended choice was a private gem that is a dependency of another private gem that is explicitly depended on by the application.
Resolution
Upgrade to 2.2.18-1.
# pacman -Syu "ruby-bundler>=2.2.18-1"
The problem has been fixed upstream in version 2.2.18.
