CVE-2026-54707

CVE-2026-54707 · OnionShare Receive mode writes uploaded files even when file uploads are disabled

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
