Description

This is an incomplete fix for GHSA-6m52-m754-pw2g. Source code may still 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.

Recommendation

Update the @nuxt/rspack-builder package to the latest compatible version. Followings are version details:

  • Affected version(s): **>= 3.15.4, < 3.21.7 >= 4.0.0, < 4.4.7**
  • Patched version(s): **3.21.7 4.4.7**
