Executive Summary

This vulnerability affects Nuxt versions 4.0.0 before 4.4.7 and 3.x before 3.21.7. It occurs because these versions fail to properly validate script-capable URLs in the navigateTo open option. As a result, attackers can supply javascript: URLs through the open parameter, which leads to the execution of arbitrary client-side scripts within the application's origin when user-controlled input is passed to navigateTo.

Impact Analysis

The vulnerability allows attackers to execute arbitrary client-side scripts in the context of the affected application. This can lead to various security issues such as cross-site scripting (XSS), which may result in data theft, session hijacking, or unauthorized actions performed on behalf of the user.
