{"apiVersion":"1.0","identifier":"CVE-2026-63003","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.","publishedAt":"2026-08-20T19:16:57","lastModifiedAt":"2026-08-21T22:16:42","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-63003","cvssScore":6.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","epssProbability":0.00239,"riskScore":0.66,"affectedProduct":"django CMS","affectedVersions":"<5.0.9","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-63003","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-63003","en":"https://www.redsauce.net/en/cves/CVE-2026-63003","fr":"https://www.redsauce.net/fr/cves/CVE-2026-63003","pt":"https://www.redsauce.net/pt/cves/CVE-2026-63003","de":"https://www.redsauce.net/de/cves/CVE-2026-63003","sk":"https://www.redsauce.net/sk/cves/CVE-2026-63003","el":"https://www.redsauce.net/el/cves/CVE-2026-63003"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-63003"}}
