The Nextcloud Desktop Client is a tool to synchronize files from Nextcloud
Server. Starting with version 3.0.0 and prior to version 3.6.5, a malicious
server administrator can gain full access to an end-to-end encrypted
folder. They can decrypt files, recover the folder structure, and add new
files. Users should upgrade the Nextcloud Desktop client to 3.6.5 to
receive a patch. No known workarounds are available.
