NVD Description

Note: Versions mentioned in the description apply only to the upstream onionshare package and not the onionshare package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

OnionShare is an open source tool that lets you securely and anonymously share files, host websites, and chat with friends using the Tor network. In affected versions it is possible to change the username to that of another chat participant with an additional space character at the end of the name string. 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.
