{"id":"CVE-2026-47671","state":"PUBLISHED","title":"Nhost CLI local configserver allows cross-origin unauthenticated read/write access to local development configuration and secrets","description":"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.","publishedAt":"2026-07-21T20:00:53.145Z","updatedAt":"2026-07-22T15:44:11.174Z","severity":{"score":5.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["nhost cli"],"affected":[{"vendor":"nhost","product":"cli","versions":[{"version":"< 1.46.0","status":"affected"}]}],"references":["https://github.com/nhost/nhost/security/advisories/GHSA-64cj-qvx5-m4f3","https://github.com/nhost/nhost/pull/4302","https://github.com/nhost/nhost/commit/e407511627d2c2c1137a70e9ca1ca31095d23479","https://github.com/nhost/nhost/releases/tag/cli@1.46.0"],"weaknesses":["CWE-306"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/47xxx/CVE-2026-47671.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-47671","state":"PUBLISHED","datePublished":"2026-07-21T20:00:53.145Z","dateUpdated":"2026-07-22T15:44:11.174Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-19T21:10:38.797Z"},"containers":{"cna":{"title":"Nhost CLI local configserver allows cross-origin unauthenticated read/write access to local development configuration and secrets","descriptions":[{"lang":"en","value":"Nhost is an open source Firebase alternative with GraphQL.
