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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.9,"severity":"medium","source":"CNA: GitHub_M","vector":"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","version":"4.0"}],"modifiedAt":1794591278857,"publishedAt":1794591278857,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-r9jc-w898-3fv6"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/nuxt/nuxt/commit/97424dd21c59b60cc7ece28576e15069ca0fdbc4"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/nuxt/nuxt/releases/tag/v4.6.4"}],"remediation":[],"revision":"25960afb3835bc161f306c0a1116243a0d3e76e370bc1d0d25319ac171f56d89","sources":[{"modifiedAt":1794591278857,"name":"CNA: GitHub_M","retrievedAt":1794593377144,"url":"https://www.cve.org/CVERecord?id=CVE-2026-128074"}],"ssvc":null,"status":"published","title":"Nuxt payload URL generation has quadratic cost for repeated slashes in the request path","updatedAt":1794593377144}
