Magic Wormhole makes it possible to get arbitrary-sized files and directories from one computer to another. Prior to 0.24.0, there is a path traversal when a receiver who specifies "--output <dir>" where that output directory currently exists (as a directory). This vulnerability is fixed in 0.24.0.
