What is port 2375?

Port 2375 is the Docker daemon REST API without TLS. If exposed to the internet, anyone can gain complete control of the host — running arbitrary commands, reading all container data, spawning new containers, or using the host for cryptomining. This is one of the most common misconfigurations leading to serious data breaches. Use port 2376 (Docker with TLS) or bind Docker exclusively to a UNIX socket.
