{"cve":"CVE-2026-61663","nvd":{"published":"2026-08-20T19:16:56.823","modified":"2026-10-26T10:10:00.140","status":"Awaiting Analysis","description":"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/<content_type_id>/structure/<object_id>/ 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-639","CWE-862"],"references":["https://github.com/django-cms/django-cms/commit/9c82abfeb25471583e23906ea1ebef9202527b04","https://github.com/django-cms/django-cms/pull/8703","https://github.com/django-cms/django-cms/releases/tag/5.0.9","https://github.com/django-cms/django-cms/security/advisories/GHSA-8qj2-c6q4-f399","https://github.com/django-cms/django-cms/security/advisories/GHSA-8qj2-c6q4-f399"],"products":[],"source":"nvd","synced_at":"2026-10-26T10:28:23.151169805+00:00"},"epss":{"cve":"CVE-2026-61663","score":0.00342,"percentile":0.27477,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-8qj2-c6q4-f399","url":"https://osv.dev/vulnerability/GHSA-8qj2-c6q4-f399","summary":"django CMS: Missing authorization in `render_object_structure` discloses non-PageContent placeholder structure to low-privileged staff","modified":"2026-09-10T12:25:51.292752883Z","packages":[{"ecosystem":"PyPI","name":"django-cms","purl":"pkg:pypi/django-cms","ranges":["<5.0.9"],"fixed":["5.0.9"]}]},{"id":"PYSEC-2026-3823","url":"https://osv.dev/vulnerability/PYSEC-2026-3823","summary":"django CMS: Missing authorization in `render_object_structure` discloses non-PageContent placeholder structure to low-privileged staff","modified":"2026-09-10T12:15:04.989023120Z","packages":[{"ecosystem":"PyPI","name":"django-cms","purl":"pkg:pypi/django-cms","ranges":["<5.0.9"],"fixed":["5.0.9"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
