How to fix?

Upgrade rubygems-update to version 2.7.9, 3.0.3 or higher.

Overview

rubygems-update is an inbuilt rubygem for updating rubygems.

Affected versions of this package are vulnerable to Arbitrary Code Injection. Gem::GemcutterUtilities#with_response may output the API response to stdout as it is. Therefore, if the API side modifies the response, escape sequence injection may occur.
