wolfictl is a command line tool for working with Wolfi. A git authentication issue in versions prior to 0.16.10 allows a local user’s GitHub token to be sent to remote servers other than github.com
. Most git-dependent functionality in wolfictl relies on its own git
package, which contains centralized logic for implementing interactions with git repositories. Some of this functionality requires authentication in order to access private repositories. A central function GetGitAuth
looks for a GitHub token in the environment variable GITHUB_TOKEN
and returns it as an HTTP basic auth object to be used with the github.com/go-git/go-git/v5
library. Most callers (direct or indirect) of GetGitAuth
use the token to authenticate to github.com only; however, in some cases callers were passing this authentication without checking that the remote git repository was hosted on github.com. This behavior has existed in one form or another since commit 0d06e1578300327c212dda26a5ab31d09352b9d0 - committed January 25, 2023. This impacts anyone who ran the wolfictl check update
commands with a Melange configuration that included a git-checkout
directive step that referenced a git repository not hosted on github.com. This also impacts anyone who ran wolfictl update <url>
with a remote URL outside of github.com. Additionally, these subcommands must have run with the GITHUB_TOKEN
environment variable set to a valid GitHub token. Users should upgrade to version 0.16.10 to receive a patch.
