Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The official rabbitmq docker images before 3.7.13-beta.1-management-alpine (Alpine specific) contain a blank password for a root user. System using the rabbitmq docker container deployed by affected versions of the docker image may allow a remote attacker to achieve root access with a blank password.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The official RabbitMQ Docker Alpine images before version 3.7.13-beta.1-management-alpine ship with a root user that has a blank password. This creates a trivial authentication bypass where remote attackers can connect to the RabbitMQ management interface or SSH into the container using the root account with no password, achieving full root access to the containerized environment.

MitigationImmediately upgrade to a patched RabbitMQ Docker image version 3.7.13-beta.1-management-alpine or later, and enforce strong authentication credentials for all users, especially the root user.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed RabbitMQ Docker image version
    Run 'docker images' and check the TAG column for the RabbitMQ image, or run 'docker inspect <container_id>' and look at the Image tag
    Affected if The image tag shows version 3.7.12 or lower, or contains 'alpine' in the tag name with no version visible that is higher than 3.7.12
  2. Confirm the image is Alpine-based
    Run 'docker inspect <image_id>' and look for 'Alpine' in the OS/Architecture fields, or check if the tag contains 'alpine'
    Affected if The image is based on Alpine Linux (tag contains 'alpine') and the version is 3.7.12 or earlier
  3. Check if the management interface port is exposed
    Run 'docker inspect <container_id>' and look for ExposedPorts in the config, or run 'docker ps' to see published ports
    Affected if Port 15672 (management UI) or 5672 (AMQP) is published to the host or accessible remotely
  4. Verify root user authentication configuration
    Check the Docker image or container for /etc/passwd entries and look for root user configuration. Attempt to access the management interface at port 15672 using default guest:guest credentials, or check if no password is required for root
    Affected if The root user has no password set, or default guest credentials work without modification, allowing unauthenticated access
  5. Check for SSH access enabled in the container
    Inspect the container for running SSH daemon (port 22) or check image Dockerfile/Entrypoint for SSH configuration
    Affected if SSH is enabled and accessible with root user and no password required

You are affected if you are running a RabbitMQ Docker Alpine image version 3.7.12 or lower with exposed management interface or SSH access, where the root user has a blank password allowing unauthenticated remote access.

Upgrade available Upgrade to a release after 3.7.12
Interim mitigation

Immediately upgrade to a patched RabbitMQ Docker image version 3.7.13-beta.1-management-alpine or later, and enforce strong authentication credentials for all users, especially the root user.

Recommended fix High confidence

RabbitMQ Docker Image >= 3.7.13 (or 3.7.13-beta.1-management-alpine for Alpine variants)

  1. 1. Stop any running containers using the affected RabbitMQ Docker image
  2. 2. Pull the fixed RabbitMQ Docker image version 3.7.13 or later (or 3.7.13-beta.1-management-alpine or newer for Alpine variants)
  3. 3. Update your docker-compose.yml or Kubernetes manifests to reference the new image version
  4. 4. Ensure any persistent volumes with the old image are properly backed up before recreation
  5. 5. Start the new container with the updated image
  6. 6. Verify that the root user now has a proper password configured or that authentication is properly enforced
  7. 7. Test RabbitMQ functionality to ensure the upgrade did not break existing applications
Caveat Minor: Ensure any automation or scripts relying on blank root password are updated; also note that Erlang/AMQP client compatibility should be verified
