Nextcloud: File drop public link can also be converted to federated share

So bear with me.

Nextcloud: Trusted servers exchange can be triggered by attacker

The trusted servers exchanged the full user list with another server. As soon as 1 federated share is created between two instances. It is questionable if...

Nextcloud: Federated shares are not password protected

Hi again, So more from me. Bare with me because this is a highly theoretical issue. But I never the less thing it should be mitigated. Or at least disclosed. Premissie: 1. user1 on serverA has a federated share established with user2 on serverB 2. the database not the full system of serverB is...

Get a public link share again plenty of those around 2. Click the 'add to your Nextcloud' 3. A federated share is added/create...
