Title

Quasar Framework: App Vite SSG page output paths can escape the configured distribution directory

Summary

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.

Vulnerability from github – Published: 2026-10-07 16:14 – Updated: 2026-10-07 16:14

Summary

Quasar Framework: App Vite SSG page output paths can escape the configured distribution directory

Details

Summary

During an SSG build, page definitions returned by getSsgPages() can provide custom dir and filename values. The builder joined those values to build.distDir and wrote the generated page without verifying that the final destination remained inside the distribution directory.

Details

A page definition containing parent-directory traversal could cause the build to create a new HTML file outside build.distDir. An existing symlink below the distribution directory could also redirect a generated file or newly created directories outside the output tree.

Quasar application configuration and SSG page definitions are trusted input by default, so this is not normally a remote file-write primitive. The issue becomes relevant when an application derives SSG page definitions from external or otherwise untrusted content, or when build configuration is compromised. Existing files are protected by the SSG renderer's no-overwrite behavior, but new files and directories can be created with the permissions of the build user.

Impact

An attacker able to influence an application's SSG page definitions could create files outside the intended build output directory during quasar build -m ssg.

Remediation

Resolve each page destination against the real build.distDir, reject absolute and parent-traversing paths, reject destinations that resolve to the output root where a file is expected, and verify existing ancestors after resolving symlinks.

Severity

5.7 (Medium)
