Affected: onionshare

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.

 https://cve.radiocsirt.org/vuln/pysec-2026-3585 PYSEC-2026-3585 — OnionShare follows symlinks in shared directories, allowing unintended disclosure of local files 2026-10-08T17:39:00.734490+00:00

Affected: PyPI: onionshare-cli

### Summary OnionShare CLI/Desktop 2.6.3 can follow symbolic links inside a selected Share or Website directory and serve the symlink target rather than limiting access to files physically contained in the selected directory. If a user shares a directory that contains attacker-supplied or otherwise untrusted symlinks, a remote recipient with access to the OnionShare service can read arbitrary local files readable by the OnionShare process that the symlink points to.

This affects the shipped `onionshare-cli` Python package and the desktop application because both call the same `onionshare_cli.web` file-indexing and streaming code.

### Details Tested repository: `https://github.com/onionshare/onionshare` at commit `8cc75e1d7e88bd31f7276733449d412bf71c8999`.

Affected product evidence: - `cli/pyproject.toml` declares `onionshare_cli` version `2.6.3`. - `desktop/pyproject.toml` declares `onionshare` version `2.6.3` and depends on `onionshare_cli` from `../cli`. - `cli/setup.py` publishes `onionshare-cli` and includes `onionshare_cli.web` plus templates/static resources. - `desktop/setup.py` publishes `onionshare` and exposes both `onionshare` and `onionshare-cli` console scripts.

Reachable default/common paths: - CLI share mode is the default mode when no `--receive`, `--website`, or `--chat` flag is provided (`cli/onionshare_cli/__init__.py:234-241`) and accepts filesystem paths from CLI arguments (`cli/onionshare_cli/__init__.py:184-189`). - CLI website mode is exposed thro…
