medium Tenable Self-Hosted Container Security Plugin ID 442159

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Nuxt is an open-source web development framework for Vue.js. In @nuxt/rspack-builder and @nuxt/webpack-
 builder versions 3.15.4 to before 3.21.6, and 4.0.0-alpha.1 to before 4.4.6, there is an incomplete fix
 for GHSA-4gf7-ff8x-hq99. Source code may be stolen during dev when using the webpack / rspack builder if
 the dev server is bound to a non-loopback address (e.g. nuxt dev --host) and the developer opens a
 malicious site on the same network. This issue has been patched in versions 3.21.6 and 4.4.6.
 (CVE-2026-45670)

Update the @nuxt/rspack-builder library and its related packages to version 3.21.6 or later.
