{"id":"CVE-2026-128070","summary":"Nuxt dev server serves files from a parent directory that contains a lockfile","details":"Nuxt is an open-source web development framework for Vue.js. From 3.5.0 until 4.6.4, Nuxt can choose a parent directory as the default workspaceDir in either of two cases: a stray parent lockfile when the project is outside a Git repository and has no workspace file above it, or a parent pnpm or Deno settings file that does not declare packages or a workspace, including when the project is inside a Git repository. When the development server is reachable from an untrusted network, Vite permits /_nuxt/@fs/ requests beneath that widened directory, allowing unauthenticated clients to read files such as credentials and SSH keys. The issue affects the development server only; production builds and projects whose parent directories contain no qualifying files are unaffected. This issue is fixed in version 4.6.4.","aliases":["GHSA-mjrq-cffv-q4qc"],"modified":"2026-11-14T02:47:33.966607093Z","published":"2026-11-13T17:20:27.855Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/128xxx/CVE-2026-128070.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-552"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/128xxx/CVE-2026-128070.json"},{"type":"FIX","url":"https://github.com/nuxt/nuxt/commit/89d3306d1976dd52ac2e73078806a3e889cbb8bd"},{"type":"WEB","url":"https://github.com/nuxt/nuxt/releases/tag/v4.6.4"},{"type":"ADVISORY","url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-mjrq-cffv-q4qc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-128070"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nuxt/nuxt","events":[{"introduced":"9683c3dad3fc31d5a2f780f6e7e785c1eeedc797"},{"fixed":"b9a6b687018a87db72832620beec55bf46abd623"},{"fixed":"89d3306d1976dd52ac2e73078806a3e889cbb8bd"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"3.5.0"},{"fixed":"4.6.4"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"},{"range":[{"fixed":"89d3306d1976dd52ac2e73078806a3e889cbb8bd"}],"source":"REFERENCES_COMMIT"},{"original_tag":"v4.6.4","range":[{"fixed":"b9a6b687018a87db72832620beec55bf46abd623"}],"source":"REFERENCES_TAG"}]}}],"versions":["v4.6.3","v4.6.2","v4.6.1","v4.6.0","v4.5.0","v4.5.2","v4.5.1","v4.4.8","v4.4.7","v4.4.6","v4.4.5","v4.4.4","v4.4.3","v4.4.2","v4.4.1","v4.4.0","v4.3.1","v4.3.0","v4.2.2","v4.2.1","v4.2.0","v4.1.3","v4.1.2","v4.1.1","v4.1.0","v4.0.3","v4.0.2","v4.0.1","v4.0.0","v4.0.0-rc.0","v4.0.0-alpha.4","v4.0.0-alpha.3","v4.0.0-alpha.2","v4.0.0-alpha.1","v3.12.2","v3.12.1","v3.12.0","v3.11.2","v3.11.1","v3.11.0","v3.10.3","v3.10.2","v3.10.1","v3.10.0","v3.9.3","v3.9.2","v3.9.1","v3.9.0","v3.8.2","v3.8.1","v3.8.0","v3.7.4","v3.7.3","v3.7.2","v3.7.1","v3.7.0","v3.6.5","v3.6.4","v3.6.3","v3.6.2","v3.6.1","v3.6.0","v3.5.3","v3.5.2","v3.5.1","v3.5.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-128070.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
