DescriptionNuxt 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.
