{"id":"CVE-2026-128074","summary":"Nuxt payload URL generation has quadratic cost for repeated slashes in the request path","details":"Nuxt is an open-source web development framework for Vue.js. From 4.6.0 until 4.6.4, _payload.json URL generation and the experimental early-404 path use a trailing-slash regular expression whose work grows quadratically with a long run of slash characters. An unauthenticated request can synchronously occupy the Node.js event loop and delay other requests when server-side rendering uses isr, swr, or cache route rules, or when experimental.early404 is enabled. Applications without those route rules and without experimental.early404, fully prerendered applications, and client-only applications are unaffected; the impact is limited to availability. This issue is fixed in version 4.6.4.","aliases":["GHSA-r9jc-w898-3fv6"],"modified":"2026-11-14T02:47:33.960506132Z","published":"2026-11-13T17:34:38.857Z","database_specific":{"cwe_ids":["CWE-1333"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/128xxx/CVE-2026-128074.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/128xxx/CVE-2026-128074.json"},{"type":"FIX","url":"https://github.com/nuxt/nuxt/commit/97424dd21c59b60cc7ece28576e15069ca0fdbc4"},{"type":"WEB","url":"https://github.com/nuxt/nuxt/releases/tag/v4.6.4"},{"type":"ADVISORY","url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-r9jc-w898-3fv6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-128074"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nuxt/nuxt","events":[{"introduced":"49da92fe0dc0cf97bd218167da822e2827232380"},{"fixed":"b9a6b687018a87db72832620beec55bf46abd623"},{"fixed":"97424dd21c59b60cc7ece28576e15069ca0fdbc4"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"4.6.0"},{"fixed":"4.6.4"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"},{"range":[{"fixed":"97424dd21c59b60cc7ece28576e15069ca0fdbc4"}],"source":"REFERENCES_COMMIT"},{"source":"REFERENCES_TAG","original_tag":"v4.6.4","range":[{"fixed":"b9a6b687018a87db72832620beec55bf46abd623"}]}]}}],"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-2026-128074.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
