Summary

Nhost is an open source Firebase alternative with GraphQL. In versions of Nhost CLI prior to 1.46.0, the hidden `nhost configserver` used by `nhost dev` exposes the Mimir GraphQL API with dummy authorization directives and permissive CORS. 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. This 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. Version 1.46.0 of Nhost CLI contains a fix.
