Official description

The LangGraph CLI is the official command-line interface for LangGraph. From 0.4.15 until 0.4.32, langgraph deploy --verbose passes a temporary registry push token on standard input to docker login --password-stdin, but the CLI subprocess helper prints command input in verbose mode. Anyone who can read resulting CI logs or terminal recordings before the token's maximum 12-hour expiration can pull deployment images or push images to that deployment's image repository. Deployments without --verbose and remote image builds are not affected, and the token alone cannot update a deployment to execute a pushed image. This issue is fixed in version 0.4.32.
