Issue in ./help/configuration/cli/set-configuration-values.md

bin/magento config:sensitive:set [--scope=“...”] [--scope-code=“...”] path value
In this case I think you should remove value from the command and add it separately via prompt. I.e. remove value from the example, indicating that it can be done, but with a notation that it leaves creds in history ( bash_history ).
Even though this is a minor vulnerability, it's still a vulnerability. It is better not to leave sensetive credentials in any history.
