What is CVE-2026-106108?
CVE-2026-106108 is a medium-severity path traversal vulnerability in @quasar app-vite, published on 13 Oct 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
Quasar Framework is a framework for building high-performance Vue.js user interfaces. From 3.1.0 until 3.3.0, @quasar/app-vite SSG page definitions returned by getSsgPages() could supply dir and filename values that were joined to build.distDir without verifying the final destination. Parent traversal or an existing symlink below the distribution directory could create new HTML files or directories outside the output tree with the build user's permissions. Application configuration and SSG page definitions are trusted by default, so exploitation requires a build process that derives them from external or otherwise less-trusted content; existing files remain protected by the renderer's no-overwrite behavior. This issue is fixed in version 3.3.0.
Weakness: CWE-22
