NVD Description

Note: Versions mentioned in the description apply only to the upstream nextcloud-desktop package and not the nextcloud-desktop package as distributed by Debian. See How to fix? for Debian:14 relevant fixed versions and status.

Nextcloud Desktop is the desktop sync client for Nextcloud. Prior to 3.16.5, when trying to manually lock a file inside an end-to-end encrypted directory, the path of the file was sent to the server unencrypted, making it possible for administrators to see it in log files. This vulnerability is fixed in 3.16.5.
