Summary

Collabora Online is a collaborative online office suite based on LibreOffice technology. Any deployment of voila dashboard allow local file inclusion. Any file on a filesystem that is readable by the user that runs the voila dashboard server can be downloaded by someone with network access to the server. Whether this still requires authentication depends on how voila is deployed. The issues affect versions 0.0.2 through 0.2.16, 0.3.0a0 through 0.3.7, 0.4.0a0 through 0.4.3, and 0.5.0a0 through 0.5.5.
