I understand, but you should think that every system that will ship with ruby 2.6 will also ship a vulnerable bundler by default and CVE-2021-43809 has a 7.3 CVSS rating.
Removing/upgrading the system bundler may be tricky.
Ruby 2.6 is still in the security maintenance phase.

Hi,
Ruby 2.6.9 ships with bundler 1.17.2, which is affected by CVE-2021-43809.
Is there a plan to upgrade it to resolve the issue?

I saw that in the past, there was an upgrade and then a downgrade because of some issue:
https://git.ruby-lang.org/ruby.git/commit/?id=91533d9ab17a08385381d87991e01e8674e069a1

Thanks a lot,
Regards
Nat
