{"id":"CVE-2026-71315","summary":"Nuxt route rules silently dropped for mixed-case paths, bypassing appMiddleware auth gates (incomplete fix for CVE-2026-53721)","details":"Nuxt is an open-source web development framework for Vue.js. From 3.21.7 until 3.21.10 and 4.5.1, mixed-case routeRules keys can fail to match case-folded lookups when router.options.sensitive is false and drop appMiddleware authorization gates. This is caused by an incomplete fix for CVE-2026-53721. This issue is fixed in 3.21.10 and 4.5.1.","aliases":["GHSA-hxvh-4h3w-prp9"],"modified":"2026-08-08T03:30:36.935179491Z","published":"2026-08-05T21:05:15.379Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71315.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-178","CWE-863"]},"references":[{"type":"WEB","url":"https://github.com/nuxt/nuxt/releases/tag/v3.21.10"},{"type":"WEB","url":"https://github.com/nuxt/nuxt/releases/tag/v4.5.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71315.json"},{"type":"ADVISORY","url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-hxvh-4h3w-prp9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71315"},{"type":"FIX","url":"https://github.com/nuxt/nuxt/commit/619963309e082190bac4a26b05f2dd155b039b81"},{"type":"FIX","url":"https://github.com/nuxt/nuxt/commit/ad624a75ad2d215f43633f6b40be346a7194d34d"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nuxt/nuxt","events":[{"introduced":"b7d57903b947e788fadfcfdf88be7951943731bf"},{"introduced":"fd806be61503f6ccad099c070a5d803777ba8a57"},{"fixed":"452dd50d92ccdf6f456b500e71d0f26baaeff796"},{"fixed":"deafc94128005346ed8ef4dd5e64f940d80377d3"},{"fixed":"619963309e082190bac4a26b05f2dd155b039b81"},{"fixed":"ad624a75ad2d215f43633f6b40be346a7194d34d"}],"database_specific":{"extracted_events":[{"introduced":"4.4.7"},{"fixed":"4.5.1"},{"introduced":"3.21.7"},{"fixed":"3.21.10"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v3.21.9","v4.5.0","v3.21.8","v4.4.8","v4.4.7","v3.21.7"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-71315.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N"}]}
