Privileged Port Exposed
mediumDetects EXPOSE instructions for ports below 1024, which traditionally require root privileges to bind, conflicting with the security best practice of running containers as non-root users.

Detects RUN instructions using Alpine Linux's apk add command without the --no-cache flag, which unnecessarily increases Docker image size by 2-5 MB.
Detects VOLUME instructions that mount the Docker socket, giving a container full control over the host's Docker daemon, equivalent to unrestricted root access.
Detects usage of the deprecated MAINTAINER instruction, which has been deprecated since Docker 1.13 in favor of LABEL instructions with standardized OCI metadata keys.
