Password field submitted using GET method

Hi there we run Acunetix scan in our Nextcloud β€œ17.0.2” and we got the below issues:
Password field submitted using GET method in the below items:

/index.php/apps/calendar/
/index.php/apps/files
/index.php/apps/files/
/index.php/apps/tasks/
/index.php/settings/admin
/index.php/settings/apps
/index.php/settings/help
/index.php/settings/user
/index.php/settings/users
/index.php/settings/users/admin

Also: HTML form without CSRF protection
in many pages examples:
/core/doc/user/
/core/doc/user/contents.html
/core/doc/user/external_storage/
/core/doc/user/pim/sync_thunderbird.html
/core/doc/user/search.html
/core/doc/user/session_management.html
/core/doc/user/user_2fa.html
/core/doc/user/userpreferences.

and many more…
Is this real? And is there any workaround or fix for them?
