      "value": "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."

      "value": "django CMS es un sistema de gestión de contenido empresarial fácil de usar y amigable para desarrolladores, impulsado por Django. Antes de la versión 5.0.9, la duplicación de páginas carece de una verificación de autorización a nivel de objeto en la página de origen. En cms/admin/forms.py, DuplicatePageForm.source acepta cualquier Página, el constructor de AddPageForm no restringe un campo de origen oculto, AddPageForm.clean no valida el origen contra el usuario, y AddPageForm.save llama a from_source. En cms/admin/pageadmin.py, duplicate y PageAdmin.has_add_permission verifican solo si un usuario del personal puede añadir una página. Un valor de origen manipulado puede, por lo tanto, copiar cada marcador de posición y plugin de una página no autorizada con permissions=False, eliminando las restricciones de vista de origen y exponiendo contenido a través de sitios o subárboles restringidos cuando CMS_PERMISSION está habilitado. Este problema está solucionado en las versiones 5.0.9."
