      "value": "Vulnerabilidad de autorización faltante en el servicio de delegación thrift y rest de Apache HBase.\n\nUna operación de escaneo en el servicio thrift/rest tiene 3 pasos: abrir, obtener (posiblemente múltiples veces), cerrar.\nEl paso de apertura devolverá un ID que se pasará de vuelta al servidor para identificar las instancias del escáner almacenadas en el lado del servidor.\nSe omitió la verificación de propietario en los pasos de obtención y cierre, lo que significa que un usuario puede obtener filas del escáner que es abierto por otros usuarios, y cerrar escáneres que pertenecen a otros usuarios.\n\nEste problema afecta a Apache HBase: desde 3.0.0-alpha-1 hasta 3.0.0-beta-1, desde 2.6.0 hasta 2.6.5, desde 2.5.0 hasta 2.5.14, hasta 2.4.*.\n\nSe recomienda a los usuarios actualizar a la versión 3.0.0-beta-2, 2.6.6 y 2.5.15, lo que soluciona el problema."
