Detailsinfo

A vulnerability was found in Nuxt up to 4.6.3. It has been rated as problematic. Affected by this issue is an unknown code block. The manipulation with an unknown input leads to a information disclosure vulnerability. Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. CVE summarizes:

Nuxt is an open-source web development framework for Vue.js. From 3.0.0 until 4.6.4, Nuxt wraps non-HTTP errors thrown during server rendering with createError and incorrectly treats the result as an error deliberately exposed by the application. In production, the error page payload (__NUXT_DATA__) and JSON error response can therefore disclose the original message and data, including an upstream $fetch URL, query-string secrets, response bodies, database hosts, or similar sensitive details, regardless of what a custom error.vue renders. Errors deliberately created with createError or showError, errors returned by useFetch or useAsyncData, and server/api routes are not affected because their client-visible behavior is intentional or follows a different path. This issue is fixed in version 4.6.4.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-128075 since 11/12/2026. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1592 by the MITRE ATT&CK project.

Upgrading to version 4.6.4 eliminates this vulnerability.
