CVE-2026-54707
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 (0.40%). 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. Prior to 2.6.4, OnionShare CLI/Desktop does not enforce the Receive mode disable_files setting in cli/onionshare_cli/web/receive_mode.py, where ReceiveModeRequest._get_file_stream() writes multipart file[] data to disk despite the text-only setting. This issue is fixed in version 2.6.4.
