Versions less than 0.1.4 of the static file server module fancy-server are vulnerable to directory traversal. An attacker can provide input such as `../` to read files outside of the served directory.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
