CVE-2026-54706
OnionShare follows symlinks in shared directories, allowing unintended disclosure of local files
MEDIUM 4.8EPSS 0.3%
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.
