Upgrade github.com/cli/go-gh/v2/pkg/auth to version 2.11.1 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure due to the auth.TokenForHost function. An attacker can redirect authentication tokens intended for specific hosts to unauthorized hosts by exploiting the improper token sourcing mechanism within a codespace environment.
Note:
This exploitation depends on the environment variables: if GITHUB_TOKEN or GH_TOKEN are set and if the application is running in a codespace that is not GitHub.com or ghe.com.
