What is CVE-2026-128072?

A security flaw in the Nuxt framework allows untrusted Origin, Referer, or Sec-Fetch-Site headers to be accepted. This occurs when the Host header matches an attacker-controlled hostname and can lead to DNS rebinding, enabling a malicious page opened by a developer to access sensitive client-side JavaScript chunks and inline source maps. This exposes compiled application source code, local filesystem paths, and potentially sensitive developer-controlled values. Mitigating this vulnerability requires developers to be cautious about opening untrusted web pages and updating to version 4.6.4, which addresses this issue.

Affected Version(s)

nuxt >= 3.0.0, < 4.6.4

rspack-builder >= 3.12.2, < 4.6.4

webpack-builder >= 3.0.0, < 4.6.4
