CVE-2026-61663Public exploitNetwork attack vector

Authenticated structure disclosure via missing object authorization

Published Aug 20, 2026 · Updated Aug 25, 2026

Missing authorization in django CMS before 5.0.9 allows remote authenticated users to read plugin structure via a CMS endpoint. The render_object_structure view accepts guessed content type and object identifiers for non-PageContent PlaceholderRelationField objects without an object-level authorization check. An active staff account is required; exposure is limited to placeholder slots, plugin trees, identifiers, labels, and object existence, not content modification.
