{"id":"CVE-2026-71320","summary":"Nuxt: Server-Side Remote Code Execution via Runtime Template Injection in Nuxt Server Island Props","details":"Nuxt is an open-source web development framework for Vue.js. From 3.4.0 until 3.21.10 and 4.5.1, an attacker can inject a template key through /__nuxt_island/ props into a dynamic component when `vue.runtimeCompiler: true` is enabled, causing template execution in the Nitro process. This issue is fixed in 3.21.10 and 4.5.1.","aliases":["GHSA-9473-5f9j-94wq"],"modified":"2026-08-08T03:30:17.474261877Z","published":"2026-08-05T21:29:51.370Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-74","CWE-94"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71320.json"},"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-2026-71320.json"},{"type":"ADVISORY","url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-9473-5f9j-94wq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71320"},{"type":"FIX","url":"https://github.com/nuxt/nuxt/commit/5b60017f7f1d5e9384cadf1d6c580b99d583c418"},{"type":"FIX","url":"https://github.com/nuxt/nuxt/commit/ee6c846338f4eb75801815dda86df1f494725859"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nuxt/nuxt","events":[{"introduced":"8aacdde48e8388c8bb11b9a5c2f59935341bfcfd"},{"introduced":"25e3a9046cc1b3dd9c1bf2c188a627b0a9446ad2"},{"fixed":"452dd50d92ccdf6f456b500e71d0f26baaeff796"},{"fixed":"deafc94128005346ed8ef4dd5e64f940d80377d3"},{"fixed":"5b60017f7f1d5e9384cadf1d6c580b99d583c418"},{"fixed":"ee6c846338f4eb75801815dda86df1f494725859"}],"database_specific":{"extracted_events":[{"introduced":"4.0.0"},{"fixed":"4.5.1"},{"introduced":"3.4.0"},{"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","v4.4.6","v3.21.6","v3.21.5","v4.4.5","v3.21.4","v4.4.4","v3.21.3","v4.4.3","v4.4.2","v3.21.2","v4.4.1","v4.4.0","v4.3.1","v3.21.1","v3.21.0","v4.3.0","v3.20.2","v4.2.2","v3.20.1","v4.2.1","v3.20.0","v4.2.0","v3.19.3","v4.1.3","v3.19.2","v4.1.2","v3.19.1","v4.1.1","v3.19.0","v4.1.0","v3.18.1","v4.0.3","v3.18.0","v4.0.2","v4.0.1","v4.0.0","v3.17.7","v3.17.6","v3.17.5","v3.17.4","v3.17.3","v3.17.2","v3.17.1","v3.17.0","v3.16.2","v3.16.1","v3.16.0","v3.15.4","v3.15.3","v3.15.2","v3.15.1","v3.15.0","v3.14.1592","v3.14.159","v3.14.0","v3.13.2","v3.13.1","v3.13.0","v3.12.4","v3.12.3","v3.12.2","v3.12.1","v3.12.0","v3.11.2","v3.11.1","v3.11.0","v3.10.3","v3.10.2","v3.10.1","v3.10.0","v3.9.3","v3.9.2","v3.9.1","v3.9.0","v3.8.2","v3.8.1","v3.8.0","v3.7.4","v3.7.3","v3.7.2","v3.7.1","v3.7.0","v3.6.5","v3.6.4","v3.6.3","v3.6.2","v3.6.1","v3.6.0","v3.5.3","v3.5.2","v3.5.1","v3.5.0","v3.4.3","v3.4.2","v3.4.1","v3.4.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-71320.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
