When a developer is running the local development environment, any process that can reach the developer's localhost service, including a web page loaded from an arbitrary origin, can query the configserver for local Nhost configuration and secrets and can mutate the local `.secrets` file.\n\nThis impacts developers using `nhost dev`: project admin secrets, JWT signing keys, webhook secrets, Grafana credentials, and custom environment variables can be read, and attacker-controlled secrets can be written to the local development project.\n\n### Details\n\nThe CLI registers a hidden `configserver` command in `cli/main.go:39` and `cli/main.go:41`. That command is used as the local development configserver image in `nhost dev`: `cli/cmd/dev/up.go:176` through `cli/cmd/dev/up.go:200` select `nhost/cli:` as the configserver image, and `cli/dockercompose/configserver.go:80` through `cli/dockercompose/configserver.go:84` run it with the `configserver` command.
