Nuxt: Incomplete fix for GHSA-934w-87qh-qr26: a `javascript:` URL prefixed with an ASCII control character executes from `<NuxtLink>` when `pages` is disabled
Impact
An 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.
This is an incomplete fix for 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.
Prefixing 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.
Both <NuxtLink custom> and the default anchor are affected, and the href is present in the server-rendered HTML.
Mitigating factors
- The application must have
pagesdisabled (nopages/directory, orpages: false). - The application must bind untrusted input to
:to. - A victim must click the rendered link.
Affected versions
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.
Patches
Fixed in nuxt@4.6.0. Nuxt 3 reached end of life on 31 July 2026 and will not receive a fix.
Anchor 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.
Workarounds
Upgrade 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 /.
