The edit and preview endpoints enforce this via `render_page()`, but the structure endpoint does not, allowing a low-privileged staff user to read the plugin structure of a view-restricted page.\n\n### Details\n`render_object_structure` (in `cms/views.py`) loads the `PageContent` object and renders `cms/toolbar/structure.html` directly. Unlike `render_object_endpoint` (used by edit/preview), which renders through `render_pagecontent` → `render_page` and calls `user_can_view_page(request.user, page)` (returning 404 when the user may not view the page), the structure endpoint performs no page-level authorization.\n\nThe rendered structure board includes each plugin's `get_short_description()`  (e.g. link names/URLs, text snippets), so the content of a restricted page is disclosed, not just its shape.\n\n### Impact\nA staff user (any account with `is_staff=True`) who lacks view permission on a  view-restricted page can retrieve that page's plugin structure and short descriptions by requesting the structure endpoint with the page's content-type id and object id.\n\nThis only applies when `CMS_PERMISSION=True` and the page has view restrictions (or `CMS_PUBLIC_FOR='staff'`). Sites without per-page view restrictions are not affected.\n\n### Patches\nFixed in 5.0.8: the structure endpoint now enforces `user_can_view_page()` for `PageContent` objects, matching edit/preview.\n\n### Workarounds\nNone other than restricting staff access. Upgrade is recommended.\n\n### Credits\nReported by the security team at the University of Sydney ([@reporter]).\n\n## Affected packages\n\n- `django-cms < 5.0.8`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `django-cms 5.0.8`","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
