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.
This bug has been fixed in Docker CLI 20.10.9. Users should update to this
version as soon as possible. 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.
