AI-suggested

Upgrade Nuxt to version 4.6.4 or later, where this issue is fixed. No other mitigation is required as the fix addresses the root cause of sensitive data exposure in error messages.

Description

A vulnerability in Nuxt versions from 3.0.0 up to but not including 4.6.4 causes sensitive information to be exposed in error messages during server rendering. Non-HTTP errors are wrapped and treated as deliberately exposed errors, leading to disclosure of original error messages and data such as upstream fetch URLs, query-string secrets, response bodies, and database hosts. This exposure occurs in the error page payload and JSON error responses, regardless of custom error page rendering. The issue is fixed in version 4.6.4.
