What is CVE-2026-32116?

Magic Wormhole is designed to facilitate the transfer of arbitrary-sized files and directories between computers. However, versions 0.21.0 to 0.22.0 have a security vulnerability that allows a malicious sender to overwrite critical local files on the receiver's machine, such as ~/.ssh/authorized_keys and .bashrc, which could lead to serious security compromises. This issue is mitigated in version 0.23.0 and highlights the importance of using the latest software versions to protect against potential attacks.
