    Summary: Path traversal in github.com/valyala/fasthttp

    Details: The fasthttp.FS request handler is vulnerable to directory traversal attacks on Windows systems, and can serve files from outside the provided root directory. URL path normalization does not handle Windows path separators (backslashes), permitting an attacker to construct requests with relative paths.
