How to fix?

Upgrade onionshare-cli to version 2.5 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 Information Exposure where an attacker with a primitive that allows for filesystem access from the context of the Onionshare process can access sensitive files in the entire user home folder.
