CVE-2022-21696
OnionShare is an open source tool that lets you securely and anonymously share files, host websites, and chat with friends using the Tor network.
Does this matter?
Lower severity and a low EPSS score (0.71%). Track it; it rarely justifies an emergency change on its own.
Description
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.
