{"id":"CVE-2026-45669","summary":"Nuxt: Reflected XSS in `navigateTo()` external redirect","details":"Nuxt is an open-source web development framework for Vue.js. From versions 3.4.3 to before 3.21.6 and 4.0.0-alpha.1 to before 4.4.6, navigateTo() with external: true generates a server-side HTML redirect body containing a \u003cmeta http-equiv=\"refresh\"\u003e tag. The destination URL is only sanitized by replacing \" with %22, leaving \u003c, \u003e, &, and ' unencoded. An attacker who can influence the URL passed to navigateTo(url, { external: true }) can break out of the content=\"…\" attribute and inject arbitrary HTML/JavaScript that executes under the application's origin. This issue has been patched in versions 3.21.6 and 4.4.6.","aliases":["GHSA-fx6j-w5w5-h468"],"modified":"2026-07-08T08:05:17.236036304Z","published":"2026-06-12T12:51:42.640Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45669.json","cwe_ids":["CWE-83"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45669.json"},{"type":"ADVISORY","url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-fx6j-w5w5-h468"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45669"},{"type":"FIX","url":"https://github.com/nuxt/nuxt/pull/35052"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nuxt/nuxt","events":[{"introduced":"1464294d6abe13b54fdb8d204732345551c8e647"},{"fixed":"1a8fff351be63bdc639a8b0a2f5a9e74dad240c9"},{"introduced":"8aacdde48e8388c8bb11b9a5c2f59935341bfcfd"},{"fixed":"30a45f7bb206a8373b9183e60eb344891a6f5bb8"}],"database_specific":{"cpe":"cpe:2.3:a:nuxt:nuxt:*:*:*:*:*:*:*:*","source":"CPE_RANGE","extracted_events":[{"introduced":"3.4.3"},{"fixed":"3.21.6"},{"introduced":"4.0.0"},{"fixed":"4.4.6"}]}}],"versions":["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"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45669.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N"}]}
