summary: Path traversal in github.com/cloudwego/hertz
description: |-
    Improper path sanitization on Windows permits path traversal attacks. Static
    file serving with the Static or StaticFS functions allows an attacker to access
    files from outside the filesystem root.

    This vulnerability does not affect non-Windows systems.
