    Summary: Username spoofing in OnionShare

    Details: OnionShare is an open source tool that lets you securely and anonymously share files, host websites, and chat with friends using the Tor network.

An adversary with access to the chat environment can use the rename feature to impersonate other participants by adding whitespace characters at the end of the username.
