Details

As written in the advisory (Markdown source, shown as plain text).

## Impact 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. ## Patches This bug has been fixed in Docker CLI 20.10.9. Users should update to this version as soon as possible. ## Workarounds Ensure that any configured `credsStore` or `credHelpers` entries in the configuration file reference an installed credential helper that is executable and on the `PATH`. ## For more information If you have any questions or comments about this advisory: * [Open an issue](https://github.com/docker/cli/issues/new/choose) * Email us at [email protected] if you think you’ve found a security bug
