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.

Quasar 框架是一个用于构建高性能 Vue.js 用户界面的框架。从版本 1.0.0 到 3.3.0， 在执行构建前会递归删除已解析的构建输出目录（ ），但在此过程中未对以下路径进行有效校验：项目根目录、用户主目录、文件系统根目录以及通过符号链接解析的外部目录。 如果存在不安全且可信赖的构建配置，那么在编译开始前，就可能删除由构建用户有权写入的数据。默认情况下，攻击者无法控制输入到 的内容，因此要利用此漏洞，需要借助已被入侵或缺乏足够信任保障的自动化流程来影响构建配置，或者由开发人员执行了错误的配置。 此问题已

Vulnerability Title
Quasar Framework: App Vite build cleanup can recursively remove unsafe configured output directories
Source: CVE Program / CVE List V5
Vulnerability Description
Quasar Framework is a framework for building high-performance Vue.js user interfaces. From 1.0.0 until 3.3.0, @quasar/app-vite recursively removed the resolved build.distDir before building without rejecting the project root, user home directory, filesystem roots, or symlink-resolved external directories. An unsafe trusted configuration can delete data writable by the build user before compilation begins. No attacker-controlled input reaches build.distDir by default, so exploitation requires compromised or less-trusted automation to influence build configuration, or a developer to run a mistaken configuration. This issue is fixed in version 3.3.0.
