WS-2022-0412

Date: August 19, 2025

Path resolution in hyper-staticfile 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.
