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 Authentication Bypass where an attacker with access to the chat environment can spoof his leave event but still persist in the chat with access to all sent messages and the possibility to write in the chat
