Nuxt Nuxt
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Nuxt是Nuxt团队开源的一个免费的开源框架。 Nuxt 4.4.7之前版本和3.21.7之前版本存在权限许可和访问控制问题漏洞，该漏洞源于在Linux上运行开发服务器时，将vite-node IPC服务器绑定到抽象命名空间Unix套接字且未设置权限限制，可能导致本地用户枚举和连接，低权限用户可利用未受保护的模块请求处理器通过SSR插件管道读取任意文件。

Vulnerability Title
Nuxt - Arbitrary File Read via World-Connectable vite-node IPC Socket on Linux
Source: CVE Program / CVE List V5
Vulnerability Description
Nuxt 4.0.0 before 4.4.7 and 3.18.0 before 3.21.7, when running the development server (nuxt dev) on Linux, binds the vite-node IPC server to an abstract-namespace Unix socket without permission restrictions, allowing local users to enumerate and connect. Unprivileged co-resident users can exploit the unprotected module request handler to read arbitrary files such as .env and SSH keys through the SSR plugin pipeline. Production builds are unaffected, as the IPC server runs only in development.
