Vite is a frontend tooling framework for javascript. The Vite dev server option server.fs.deny
can be bypassed on case-insensitive file systems using case-augmented versions of filenames. Notably this affects servers hosted on Windows. This bypass is similar to CVE-2023-34092 – with surface area reduced to hosts having case-insensitive filesystems. Since picomatch
defaults to case-sensitive glob matching, but the file server doesn’t discriminate; a blacklist bypass is possible. By requesting raw filesystem paths using augmented casing, the matcher derived from config.server.fs.deny
fails to block access to sensitive files. This issue has been addressed in [email protected], [email protected], [email protected], and [email protected]. Users are advised to upgrade. Users unable to upgrade should restrict access to dev servers.
