{"id":"CVE-2026-61663","summary":"django CMS: Missing authorization in `render_object_structure` discloses non-PageContent placeholder structure to low-privileged staff","details":"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/\u003ccontent_type_id\u003e/structure/\u003cobject_id\u003e/ 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.","aliases":["GHSA-8qj2-c6q4-f399","PYSEC-2026-3823"],"modified":"2026-09-11T03:30:57.874530069Z","published":"2026-08-20T18:07:28.005Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-639","CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61663.json"},"references":[{"type":"WEB","url":"https://github.com/django-cms/django-cms/releases/tag/5.0.9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61663.json"},{"type":"ADVISORY","url":"https://github.com/django-cms/django-cms/security/advisories/GHSA-8qj2-c6q4-f399"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61663"},{"type":"FIX","url":"https://github.com/django-cms/django-cms/commit/9c82abfeb25471583e23906ea1ebef9202527b04"},{"type":"FIX","url":"https://github.com/django-cms/django-cms/pull/8703"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/django-cms/django-cms","events":[{"introduced":"0"},{"fixed":"9c82abfeb25471583e23906ea1ebef9202527b04"},{"fixed":"d7eeb6526bd757cfcdf28122066f39803990c5e4"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"5.0.9"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["5.0.8","5.0.7","5.0.6","5.0.5","5.0.4","5.0.3","5.0.2","5.0.1","5.0.0","5.0.0a1","4.0.0dev11","4.0.0","3.5.2","3.5.1","3.5.0","3.5.0rc1","3.4.2","3.4.1","3.4.0","3.4.0rc3","3.4.0rc2","3.4.0rc1","3.3.0","3.3.0.rc4","3.3.0.rc3","3.3.0.rc2","3.2.0","3.2.0.rc14","3.2.0.rc13","3.2.0.rc12","3.2.0.rc11","3.2.0.rc10","3.2.0.rc9","3.2.0.rc8","3.2.0.rc7","3.2.0.rc6","3.2.0.rc5","3.2.0.rc4","3.2.0.rc3","3.2.0.rc1","2.3.4","3.1","3.0.9","3.0.10","3.0.8","3.0.7","3.0.6","3.0.5","3.0.3","3.0.4","3.0.2","3.0.1","3.0","3.0c2","3.0c1","temporary","3.0.0.beta3","3.0.0.beta2","3.0.0.beta","2.4.1","2.4.0","2.4.0.rc1","2.3.5","2.1.4","2.2","2.3.3","show","2.3.2","2.3.2.rc1","2.3","2.3rc1","2.1.3","2.1.2","2.1.1","2.1.0","2.1.0.rc3","2.1.0.rc2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-61663.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
