Django 2.2.16 fixes two security issues and two data loss bugs in 2.2.15.
On Python 3.7+, 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
management command.
You should review and manually fix permissions on existing intermediate-level directories.
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).
Fixed a data loss possibility in the
select_for_update()
. When using
related fields pointing to a proxy model in the of
argument, the
corresponding model was not locked (#31866).
Fixed a data loss possibility, following a regression in Django 2.0, when copying model instances with a cached fields value (#31863).
