Access Controls
etcd creates certain directory paths (etcd data directory and the directory path when provided to automatically generate self-signed certificates for TLS connections with clients) with restricted access permissions (700) by using the os.MkdirAll. This function does not perform any permission checks when a given directory path exists already.
github.com/etcd-io/etcd/pkg/fileutil
Make sure these directories have the desired permit (700).
