{"cve":"CVE-2026-47671","nvd":{"published":"2026-07-21T20:17:01.473","modified":"2026-10-24T19:10:00.127","status":"Analyzed","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-306"],"references":["https://github.com/nhost/nhost/commit/e407511627d2c2c1137a70e9ca1ca31095d23479","https://github.com/nhost/nhost/pull/4302","https://github.com/nhost/nhost/releases/tag/cli@1.46.0","https://github.com/nhost/nhost/security/advisories/GHSA-64cj-qvx5-m4f3","https://github.com/nhost/nhost/security/advisories/GHSA-64cj-qvx5-m4f3"],"products":["nhost:cli"],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-47671","score":0.00354,"percentile":0.28842,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-64cj-qvx5-m4f3","url":"https://osv.dev/vulnerability/GHSA-64cj-qvx5-m4f3","summary":"Nhost CLI local configserver allows cross-origin unauthenticated read/write access to local development configuration and secrets","modified":"2026-06-25T18:56:16.236929704Z","packages":[{"ecosystem":"Go","name":"github.com/nhost/nhost","purl":"pkg:golang/github.com/nhost/nhost","ranges":["<0.0.0-20260518172022-e407511627d2"],"fixed":["0.0.0-20260518172022-e407511627d2"]}]},{"id":"GO-2026-5166","url":"https://osv.dev/vulnerability/GO-2026-5166","summary":"Nhost CLI local configserver allows cross-origin unauthenticated read/write access to local development configuration and secrets in github.com/nhost/nhost","modified":"2026-06-25T18:45:28.028014439Z","packages":[{"ecosystem":"Go","name":"github.com/nhost/nhost","purl":"pkg:golang/github.com/nhost/nhost","ranges":["<0.0.0-20260518172022-e407511627d2"],"fixed":["0.0.0-20260518172022-e407511627d2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
