CVE-2026-42448 Details
Description
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.
A path traversal vulnerability has been identified in Magic Wormhole versions prior to 0.24.0. This issue occurs when a receiver specifies an output directory that already exists as a directory. The vulnerability allows for arbitrary-sized files and directories to be transferred from one computer to another, but with the potential for unintended file overwrites due to the path traversal.
Users can upgrade to Magic Wormhole version 0.24.0 or later to address this vulnerability. Alternatively, ensure that the local target directory specified with the '--output' option does not already exist as a directory.
