CVE-2026-54706

CVE-2026-54706 · OnionShare follows symlinks in shared directories, allowing unintended disclosure of local files

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 follows symbolic links in cli/onionshare_cli/web/send_base_mode.py through SendBaseModeWeb.set_file_info() and stream_individual_file(), allowing remote recipients of Share or Website mode to read local files outside the selected directory. This issue is fixed in version 2.6.4.
