What is CVE-2026-47671?

The Nhost CLI, used by developers for local environment setups, contains a vulnerability in versions prior to 1.46.0 that can expose critical project secrets. The hidden command nhost configserver, utilized by nhost dev, inadvertently allows access to the Mimir GraphQL API with weak authorization settings and permissive Cross-Origin Resource Sharing (CORS). This enables an attacker who accesses the local service to query for sensitive configuration data such as JWT signing keys, project admin secrets, and custom environment variables, potentially leading to unauthorized changes to the local .secrets file. The issue affects developers running local instances and has been addressed in version 1.46.0.

Affected Version(s)
