Detailsinfo

A vulnerability classified as problematic has been found in Nuxt up to 4.5.99. Affected is an unknown code block of the component NuxtLink/no-pages router. The manipulation with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79.

This is going to have an impact on integrity. CVE summarizes:

Nuxt is an open-source web development framework for Vue.js. Prior to 4.6.0, an incomplete fix for CVE-2026-53722 allows an application with pages disabled to render a script-capable URL through NuxtLink when attacker-controlled input bound to to is prefixed with an ASCII C0 control character. The no-pages router classifies the value as an internal route before the earlier protocol check and passes it to the rendered anchor href; browsers remove the leading control character and interpret the remaining javascript: URL. The default anchor and NuxtLink custom output are affected, the unsafe href is present in server-rendered HTML, and a victim must click the link for script to execute in the application's origin. This issue is fixed in version 4.6.0.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-114130 since 10/20/2026. The exploitability is told to be easy. It is possible to launch the attack remotely.

This vulnerability is assigned to T1059.007 by the MITRE ATT&CK project.
