      "value": "Apache Neethi does not properly detect circular references in policy definitions. When a WS-Policy document contains circular policy references (where Policy A references Policy B which references Policy A), the policy normalization process can enter an infinite loop or cause excessive recursion, leading to a stack overflow or application hang. An attacker can craft malicious policy documents with circular references to cause a Denial of Service condition\n\nUsers are recommended to upgrade to version 3.2.2, which fixes this issue."

      "value": "Apache Neethi no detecta correctamente las referencias circulares en las definiciones de políticas. Cuando un documento WS-Policy contiene referencias circulares de políticas (donde la Política A hace referencia a la Política B que hace referencia a la Política A), el proceso de normalización de políticas puede entrar en un bucle infinito o causar una recursión excesiva, lo que lleva a un desbordamiento de pila o a un bloqueo de la aplicación. Un atacante puede crear documentos de políticas maliciosos con referencias circulares para causar una condición de denegación de servicio.\n\nSe recomienda a los usuarios actualizar a la versión 3.2.2, que corrige este problema."
