An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-47200 exists.\n\nAffected packages and fixed versions:\n- @nuxt/nitro-server (npm): affected from 3.20.0; fixed in 3.21.6\n- @nuxt/nitro-server (npm): affected from 3.20.0; fixed in 3.21.6\n- @nuxt/nitro-server (npm): affected from 4.2.0; fixed in 4.4.6\n- @nuxt/nitro-server (npm): affected from 4.2.0; fixed in 4.4.6\n- nuxt (npm): affected from 3.11.0; fixed in 3.21.6\n- nuxt (npm): affected from 3.11.0; fixed in 3.21.6\n- nuxt (npm): affected from 4.0.0-alpha.1; fixed in 4.4.6\n- nuxt (npm): affected from 4.0.0-alpha.1; fixed in 4.4.6\n\nTask:\n1. 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-2026-47200/ (Markdown: https://insights.sbomify.com/CVE-2026-47200/index.md)","id":"CVE-2026-47200","markdown":"https://insights.sbomify.com/CVE-2026-47200/index.md","name":"CVE-2026-47200","record":{"aliases":["GHSA-hg3f-28rg-4jxj"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Nuxt web framework","requires_auth":"none","summary":"Attackers can bypass route middleware protections on server island pages in Nuxt when experimental component islands are enabled.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"nuxt","vendor":"nuxt"},{"product":"nuxt\\/nitro-server","vendor":"nuxt"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"Nuxt is an open-source web development framework for Vue.js.

Until this fix, requests through that endpoint rendered the page component directly via the SSR renderer without instantiating Vue Router, which meant route middleware declared on the page (including definePageMeta({ middleware })) did not run.
