Insufficiently Protected Credentials

Summary

Docker CLI is the command line interface for the Docker container runtime. A bug was found in the Docker CLI where running "docker login my-private-registry.example.com" with a misconfigured configuration file (typically "~/.docker/config.json") listing a "credsStore" or "credHelpers" that could not be executed would result in any provided credentials being sent to "registry-1.docker.io" rather than the intended private registry. For users unable to update, ensure that any configured "credsStore" or "credHelpers" entries in the configuration file reference an installed credential helper that is executable and on the PATH. The vulnerability affects Docker CLI versions prior to 20.10.9.
