{"id":"CVE-2026-128077","summary":"Nuxt: Incomplete fix for CVE-2026-119200: a leading `//` in the request path bypasses `server/middleware` path checks and server route rules on page routes","details":"Nuxt is an open-source web development framework for Vue.js. From 4.6.0 until 4.6.4, Nuxt parses a request path beginning with // as a URL host before rendering a page, while Nitro server/middleware and routeRules continue to evaluate the original path. An unauthenticated request such as //x/admin can therefore resolve to the /admin page without route-scoped serverHandlers, server/middleware path checks, redirects, or security headers configured for /admin. API handlers in server/api and server/routes, appMiddleware, page middleware are unaffected. This issue is fixed in version 4.6.4.","aliases":["GHSA-r99w-jh2x-3mg9"],"modified":"2026-11-14T02:47:33.960760428Z","published":"2026-11-13T17:41:28.932Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-436","CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/128xxx/CVE-2026-128077.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/128xxx/CVE-2026-128077.json"},{"type":"FIX","url":"https://github.com/nuxt/nuxt/commit/75c12c6fb4c22ec2cbde0051da24776d2dffa868"},{"type":"WEB","url":"https://github.com/nuxt/nuxt/releases/tag/v4.6.4"},{"type":"ADVISORY","url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-r99w-jh2x-3mg9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-128077"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nuxt/nuxt","events":[{"introduced":"49da92fe0dc0cf97bd218167da822e2827232380"},{"fixed":"b9a6b687018a87db72832620beec55bf46abd623"},{"fixed":"75c12c6fb4c22ec2cbde0051da24776d2dffa868"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StringRangeExpression","range":[{"introduced":"4.6.0"},{"fixed":"4.6.4"}]},{"source":"REFERENCES_COMMIT","range":[{"fixed":"75c12c6fb4c22ec2cbde0051da24776d2dffa868"}]},{"original_tag":"v4.6.4","range":[{"fixed":"b9a6b687018a87db72832620beec55bf46abd623"}],"source":"REFERENCES_TAG"}]}}],"versions":["v4.6.3","v4.6.2","v4.6.1","v4.6.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-128077.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
