{"schema_version":"1.9.0","id":"GHSA-jjm6-p2m9-9w4x","published":"2026-10-22T16:51:37Z","modified":"2026-10-22T17:00:04.471901983Z","aliases":["CVE-2026-114130"],"summary":"Nuxt: Incomplete fix for GHSA-934w-87qh-qr26: a `javascript:` URL prefixed with an ASCII control character executes from `<NuxtLink>` when `pages` is disabled","details":"## Impact\n\nAn application that renders `<NuxtLink :to=\"...\">` with a value it does not control can be made to render an anchor whose `href` executes script in the application's origin when clicked.\n\nThis is an incomplete fix for [GHSA-934w-87qh-qr26](https://github.com/nuxt/nuxt/security/advisories/GHSA-934w-87qh-qr26) (CVE-2026-53722). It only affects applications running without a `pages/` directory, where `pages` resolves to `false` and Nuxt registers its own router in place of vue-router. Applications using vue-router are not affected.\n\nPrefixing `javascript:` with an ASCII C0 control character, for example `%01`, meant the value was not recognised as having a protocol. It was classified as an internal route and so never reached the protocol check added in GHSA-934w-87qh-qr26, and the router used for `pages: false` passed it through to the rendered `href` unchanged. Browsers strip the leading control character and run the result as a script URL.\n\nBoth `<NuxtLink custom>` and the default anchor are affected, and the `href` is present in the server-rendered HTML.\n\n## Mitigating factors\n\n- The application must have `pages` disabled (no `pages/` directory, or `pages: false`).\n- The application must bind untrusted input to `:to`.\n- A victim must click the rendered link.\n\n## Affected versions\n\n`nuxt` `<4.6.0`, including all Nuxt 3 releases. Versions before `4.4.7` and `3.21.7` are also affected by GHSA-934w-87qh-qr26.\n\n## Patches\n\nFixed in `nuxt@4.6.0`. Nuxt 3 reached end of life on 31 July 2026 and will not receive a fix.\n\nAnchor `href` values are now checked for script-capable protocols wherever they are rendered, including the router used when `pages` is disabled. Protocol detection also moved to the platform `URL` parser, so a URL is classified the same way the browser will read it.\n\n## Workarounds\n\nUpgrade to `nuxt@4.6.0` or later. If you cannot upgrade, including on Nuxt 3, validate values before binding them to `:to`, for example by rejecting anything that is not a path beginning with a single `/`.","affected":[{"package":{"name":"nuxt","ecosystem":"npm","purl":"pkg:npm/nuxt"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"4.6.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-jjm6-p2m9-9w4x/GHSA-jjm6-p2m9-9w4x.json"}}],"references":[{"type":"WEB","url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-jjm6-p2m9-9w4x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-114130"},{"type":"WEB","url":"https://github.com/nuxt/nuxt/pull/36459"},{"type":"WEB","url":"https://github.com/nuxt/nuxt/commit/355ed9565127ff9b1453deb7160059ed55b3cb85"},{"type":"WEB","url":"https://github.com/nuxt/nuxt/commit/df46569d5d3c7a7799de54c328634168fbae70bb"},{"type":"PACKAGE","url":"https://github.com/nuxt/nuxt"},{"type":"WEB","url":"https://github.com/nuxt/nuxt/releases/tag/v4.6.0"}],"database_specific":{"cwe_ids":["CWE-79"],"github_reviewed":true,"github_reviewed_at":"2026-10-22T16:51:37Z","nvd_published_at":"2026-10-21T18:17:25Z","severity":"LOW"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
