    Lock the pc, if you leave and lock the db, if pc is locked, lid is closed and this is absolute a non-issue.

    German BSI is sometimes a little bit over motivated ;-)

      You don’t even need to lock the pc, locking the db is sufficient. The issue allows changing the settings on unlocked databases without needing to re-confirm (at least according to the article).

      there is.

      But I agree that the UI distracts from the fundamentals in these early days, still

      On Jerboa(List View) the link is on the thumbail, maybe it’s the same on the browser version. Keep in mind that the article on heise is in german.

      It’s a denial of service vulnerability. Requiring the existing master password to change the master password will stop a drive by miscreant denying you access to your db. And password change system I’ve ever used has required the existing password to he entered first.

      Likewise a full db export feel like a big enough deal to require authorization.

      If you’re careful and lock your machine when you leave it then you should be pretty safe. I’m surprised these aren’t already features.

        No, requiring the existing master password won’t help. A drive by miscreant with access to an unlocked computer with an unlocked DB can delete all the DB entries. If the DB is locked they can just delete the DB file. KeePassXC can’t defend against this, that takes properly functioning versioned backups.

          yeah, maybe denial of service isn’t it. I replied to a comment above why I think it should still be protected functionality to help prevent data leak.

          Yeah, that’s fair. But a full db export that they could then email themselves. It’d be nice to have some more protection against that. Or Change the master password and email the encrypted file to themselves.
