Description
This 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.
Recommendation
Update the @nuxt/rspack-builder package to the latest compatible version. Followings are version details:
Affected version(s): **>= 4.0.0-alpha.1, <= 4.4.5 >= 3.15.4, <= 3.21.5** Patched version(s): **4.4.6 3.21.6**
