      "value": "django CMS is an easy-to-use and developer-friendly enterprise content management system powered by Django. Prior to 5.0.8, the move_plugin endpoint in cms/admin/placeholderadmin.py accepts an attacker-controlled plugin_parent value without rejecting a plugin’s own identifier or a descendant identifier. A staff user with plugin-change permission under CMS_PERMISSION can create a parent_id cycle in the plugin tree. The _get_descendants_cte and _get_ancestors_cte queries in cms/models/pluginmodel.py have no cycle guard, so get_descendants() and later rendering, copy, or delete operations can recurse indefinitely or reach a database recursion limit, corrupting the tree and consuming request workers. This issue is fixed in versions 5.0.8."

      "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 5.0.8, el endpoint move_plugin en cms/admin/placeholderadmin.py acepta un valor plugin_parent controlado por el atacante sin rechazar el propio identificador de un plugin o un identificador descendiente. Un usuario del personal con permiso de cambio de plugin bajo CMS_PERMISSION puede crear un ciclo de parent_id en el árbol de plugins. Las consultas _get_descendants_cte y _get_ancestors_cte en cms/models/pluginmodel.py no tienen una protección contra ciclos, por lo que get_descendants() y las operaciones posteriores de renderizado, copia o eliminación pueden recursar indefinidamente o alcanzar un límite de recursión de la base de datos, corrompiendo el árbol y consumiendo trabajadores de solicitudes. Este problema se corrige en las versiones 5.0.8."
