Upgrade onionshare-cli to version 2.6.4 or higher.
Overview
onionshare-cli is a software that lets you securely and anonymously send and receive files. It works by starting a web server, making it accessible as a Tor onion service, and generating an unguessable web address so others can download files from you, or upload files to you. It does not require setting up a separate server or using a third party file-sharing service.
Affected versions of this package are vulnerable to Symlink Attack in the set_file_info process. An attacker can access sensitive local files by supplying a directory containing a symbolic link to a file outside the intended shared directory, which is then served to remote recipients through the file sharing service.
