Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-114131/ (Markdown: https://insights.sbomify.com/CVE-2026-114131/index.md)","id":"CVE-2026-114131","markdown":"https://insights.sbomify.com/CVE-2026-114131/index.md","name":"CVE-2026-114131","record":{"aliases":["GHSA-6gq8-jgmh-3ffp"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-436","name":"Interpretation Conflict"}],"description":"Nuxt is an open-source web development framework for Vue.js. From 3.11.0 until 3.21.4 and 4.4.4, Nuxt compares route-rule keys with the raw request path while route resolution decodes dynamic and catch-all parameters, allowing a percent-encoded segment to resolve to a protected page without matching the routeRules entry intended for that path. As a result, appMiddleware can be skipped during server rendering and an unauthenticated requester can receive the gated page and its SSR data. The same mismatch affects app-manifest rules including redirect, appLayout, ssr, prerender, and payload flags derived from cache, isr, and swr. This vulnerability is fixed in 4.4.4 and 3.21.4.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Nuxt: Route rules are matched against the raw request path, so a percent-encoded segment can bypass `appMiddleware` on dynamic and catch-all routes","id":"CVE-2026-114131","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":4,"n_references":5,"next":{"headline":"Nuxt: Server-side route rules (`redirect`, `headers`, `proxy`, `ssr`) are skipped for case-variant paths when routing is case-insensitive","id":"CVE-2026-114132"},"packages":[{"ecosystem":"npm","fixed":["3.21.4"],"introduced":["3.11.0"],"last_affected":[],"package":"nuxt","purl":null,"source":"GHSA-6gq8-jgmh-3ffp"},{"ecosystem":"npm","fixed":["3.21.4"],"introduced":["3.11.0"],"last_affected":[],"package":"nuxt","purl":"pkg:npm/nuxt","source":"GHSA-6gq8-jgmh-3ffp"},{"ecosystem":"npm","fixed":["4.4.4"],"introduced":["4.0.0"],"last_affected":[],"package":"nuxt","purl":null,"source":"GHSA-6gq8-jgmh-3ffp"},{"ecosystem":"npm","fixed":["4.4.4"],"introduced":["4.0.0"],"last_affected":[],"package":"nuxt","purl":"pkg:npm/nuxt","source":"GHSA-6gq8-jgmh-3ffp"}],"prev":{"headline":"Nuxt: Incomplete fix for GHSA-934w-87qh-qr26: a `javascript:` URL prefixed with an ASCII control character executes from `\u003cNuxtLink\u003e` when `pages` is disabled","id":"CVE-2026-114130"},"products":["nuxt"],"published":"2026-10-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-21","vendors":["nuxt"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-114131/"}
