github.com/rancher/rke2/pkg/cli/defaults is a next-generation Kubernetes distribution for Rancher

Affected versions of this package are vulnerable to Incorrect Permission Assignment for Critical Resource in the form of weak Access Control Lists (ACL) on sensitive files on Windows nodes. A user in the groups BUILTIN\Users or NT AUTHORITY\Authenticated Users may be able to escalate privileges due to the following files and patterns not being adequately protected:

C:\etc\rancher\wins\config
C:\var\lib\rancher\agent\rancher2_connection_info.json
C:\etc\rancher\rke2\config.yaml.d\50-rancher.yaml
C:\var\lib\rancher\agent\applied\*-*-applied.plan
C:\usr\local\bin\rke2
C:\var\lib\rancher\capr\idempotence\idempotent.sh
C:\etc\rancher\node\password
C:\var\lib\rancher\rke2\agent\logs\kubelet.log
C:\var\lib\rancher\rke2\data\v1.**.**-rke2r*-windows-amd64-*\bin\*
C:\var\lib\rancher\rke2\bin\*
