{"id":"CVE-2026-63003","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-63003","generatedAt":"2026-10-28T00:52:17.520Z","title":"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.","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.","published":"2026-08-20T19:16:57.000Z","lastModified":"2026-10-26T10:10:00.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-639","CWE-862"],"affected":[],"epss":{"score":0.00415,"percentile":0.35547,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.41%).
