## Description
### Impact
The secure view feature of the rich documents app can be bypassed by using unprotected internal API endpoint of the rich documents app.
### Patches
It is recommended that the Nextcloud Office app (richdocuments) is upgraded to 8.0.0-beta.1, 7.0.2 or 6.3.2.
### Mitigation
To enforce the confidentiality of your files it is crucial to restrict the ability to download the documents.
This includes ensuring that your [WOPI configuration]() is configured to only serve documents between Nextcloud and Collabora. It is highly recommended to define the list of Collabora server IPs as the allow list within the Office admin settings of Nextcloud.
