{"cve":"CVE-2026-63003","nvd":{"published":"2026-08-20T19:16:57.163","modified":"2026-10-26T10:10:00.140","status":"Deferred","description":"django CMS is an easy-to-use and developer-friendly enterprise content management system powered by Django. Prior to 5.0.9, page duplication lacks an object-level authorization check on the source page. In cms/admin/forms.py, DuplicatePageForm.source accepts any Page, the AddPageForm constructor does not narrow a hidden source field, AddPageForm.clean does not validate the source against the user, and AddPageForm.save calls from_source. In cms/admin/pageadmin.py, duplicate and PageAdmin.has_add_permission check only whether a staff user may add a page. A crafted source value can therefore copy every placeholder and plugin from an unauthorized page with permissions=False, stripping source view restrictions and exposing content across sites or restricted subtrees when CMS_PERMISSION is enabled. 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:H/I:N/A:N","score":6.5},"cwes":["CWE-639","CWE-862"],"references":["https://github.com/django-cms/django-cms/commit/3e1ccf7573eb1a74ebbbfaaa812c1f5cadf14e6c","https://github.com/django-cms/django-cms/pull/8713","https://github.com/django-cms/django-cms/releases/tag/5.0.9","https://github.com/django-cms/django-cms/security/advisories/GHSA-6x92-6vx4-5fwr"],"products":[],"source":"nvd","synced_at":"2026-10-26T10:28:23.151169805+00:00"},"epss":{"cve":"CVE-2026-63003","score":0.00415,"percentile":0.35517,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-6x92-6vx4-5fwr","url":"https://osv.dev/vulnerability/GHSA-6x92-6vx4-5fwr","summary":"django CMS: Broken access control in page *Duplicate* allows reading the content of any page (cross-site / restriction bypass)","modified":"2026-09-10T12:25:36.931395327Z","packages":[{"ecosystem":"PyPI","name":"django-cms","purl":"pkg:pypi/django-cms","ranges":["<5.0.9"],"fixed":["5.0.9"]}]},{"id":"PYSEC-2026-3821","url":"https://osv.dev/vulnerability/PYSEC-2026-3821","summary":"django CMS: Broken access control in page *Duplicate* allows reading the content of any page (cross-site / restriction bypass)","modified":"2026-09-10T12:15:03.041235202Z","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).
