[dependabot]

Bumps django-cms from 3.4.5 to 3.4.7.

Changelog

Sourced from django-cms's changelog.

3.4.7 (2020-07-21)

• Removed extra quotation mark from the sideframe button template
• Fixed a bug where xframe options were processed by clickjacking middleware when page was served from cache, rather then get this value from cache
• Fixed a bug where cached page permissions overrides global permissions
• Fixed a bug where editing pages with primary keys greater than 9999 would throw an exception.
• Fixed broken wizard page creation when no language is set within the template context (see #5828).
• Fixed a security vulnerability in the plugin_type url parameter to insert JavaScript code.

3.4.6 (2018-03-26)

• Changed the way drag and drop works in the page tree. The page has to be selected first before moving.
• Fixed a bug where the cms alias plugin leaks context into the rendered aliased plugins.
• Fixed a bug where users without the "Change advanced settings" permission could still change a page's template.
• Added on_delete to ForeignKey and OneToOneField to silence Django deprecation warnings.
• Fixed a bug where the sitemap would ignore the public setting of the site languages and thus display hidden languages.
• Fixed an AttributeError raised when adding or removing apphooks in Django 1.11.
• Fixed an InconsistentMigrationHistory error raised when the contenttypes app has a pending migration after the user has applied the 0010_migrate_use_structure migration.
• Fixed a bug where plugins rendered multiple times won't be editable
