+# Improper validation of Windows paths could lead to directory traversal attack
+
+`tower_http::services::fs::ServeDir` didn't correctly validate Windows paths
+meaning paths like `/foo/bar/c:/windows/web/screen/img101.png` would be allowed
+and respond with the contents of `c:/windows/web/screen/img101.png`. Thus users
+could potentially read files anywhere on the filesystem.
+
+This only impacts Windows. Linux and other unix likes are not impacted by this.
+
+See [tower-http#204] for more details.
