CVE-2026-45670

5.9 mediumEPSS 0.2%

Medium (5.9) in nuxt. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in @nuxt/rspack-builder 3.21.6, 4.4.6.

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.
