# Note di rilascio di Django 3.0.10

*1 Settembre 2020*

Django 3.0.10 fixes two security issues and two data loss bugs in 3.0.9.

## CVE-2020-24583: Incorrect permissions on intermediate-level directories on Python 3.7+

On Python 3.7+, [`FILE_UPLOAD_DIRECTORY_PERMISSIONS`](/it/4.0/ref/settings/#std-setting-FILE_UPLOAD_DIRECTORY_PERMISSIONS) mode was not
applied to intermediate-level directories created in the process of uploading
files and to intermediate-level collected static directories when using the
[`collectstatic`](/it/4.0/ref/contrib/staticfiles/#django-admin-collectstatic) management command.

You should review and manually fix permissions on existing intermediate-level
directories.

## CVE-2020-24584: Permission escalation in intermediate-level directories of the file system cache on Python 3.7+

On Python 3.7+, the intermediate-level directories of the file system cache had
the system’s standard umask rather than `0o077` (no group or others
permissions).

## Correzioni di bug

- Fixed a data loss possibility in the
  [`select_for_update()`](/it/4.0/ref/models/querysets/#django.db.models.query.QuerySet.select_for_update). When using
  related fields pointing to a proxy model in the `of` argument, the
  corresponding model was not locked ([#31866](https://code.djangoproject.com/ticket/31866)).
- Fixed a data loss possibility, following a regression in Django 2.0, when
  copying model instances with a cached fields value ([#31863](https://code.djangoproject.com/ticket/31863)).
