Title

django CMS: Structure endpoint bypasses page-view permission

Summary

django CMS is an easy-to-use and developer-friendly enterprise content management system powered by Django. Prior to 5.0.8, render_object_structure in cms/views.py renders cms/toolbar/structure.html for a PageContent object without calling user_can_view_page(). Any staff account can request a restricted page’s structure when CMS_PERMISSION is enabled and the page has view restrictions or CMS_PUBLIC_FOR is set to staff. The response exposes plugin get_short_description() values, including link names, URLs, and text snippets, rather than only the page shape. This issue is fixed in versions 5.0.8.

Severity

Vulnerability from github – Published: 2026-08-20 18:42 – Updated: 2026-08-20 18:42

Summary

django CMS: Structure endpoint bypasses page-view permission

Details

Summary

The structure-board endpoint (render_object_structure) renders a page's plugin structure without verifying that the requesting user is allowed to view the page. 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.

Details

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.

The 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.

Impact

A 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.

This 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.

Patches

Fixed in 5.0.8: the structure endpoint now enforces user_can_view_page() for PageContent objects, matching edit/preview.

Workarounds

None other than restricting staff access. Upgrade is recommended.

  "details": "### Summary\nThe structure-board endpoint (`render_object_structure`) renders a page\u0027s plugin structure without verifying that the requesting user is allowed to view the page. 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` \u2192 `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\u0027s `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\u0027s plugin structure and short descriptions by requesting the structure endpoint with the page\u0027s content-type id and object id.\n\nThis only applies when `CMS_PERMISSION=True` and the page has view restrictions (or `CMS_PUBLIC_FOR=\u0027staff\u0027`). 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]).",
