# CVE-2026-61663

> 4.3 MEDIUM · 🧪 PoC

## Beschreibung

django CMS is an easy-to-use and developer-friendly enterprise content management system powered by Django. Prior to 5.0.9, render_object_structure fails to authorize non-PageContent objects that use PlaceholderRelationField. An active staff user without cms.use_structure or model-level view or change permission can request the //admin/cms/placeholder/object//structure// endpoint with guessed content_type_id and object_id values. The response discloses placeholder slot names, plugin trees, plugin identifiers, labels, and object existence for frontend-editable objects. The fix applies user_can_view_placeholder_source to the non-PageContent branch while keeping the structure board read-only for view-only users. This issue is fixed in versions 5.0.9.
