      "value": "SHIRASAGI is a Content Management System. Prior to version 1.18.0, SHIRASAGI is vulnerable to a Post-Unicode normalization issue. This happens when a logical validation or a security check is performed before a Unicode normalization. The Unicode character equivalent of a character would resurface after the normalization. The fix is initially performing the Unicode normalization and then strip for all whitespaces and then checking for a blank string. This issue has been fixed in version 1.18.0.\n"

Esto sucede cuando se realiza una validaci\u00f3n l\u00f3gica o una verificaci\u00f3n de seguridad antes de una normalizaci\u00f3n Unicode. El car\u00e1cter Unicode equivalente a un car\u00e1cter resurgir\u00eda despu\u00e9s de la normalizaci\u00f3n. La soluci\u00f3n consiste inicialmente en realizar la normalizaci\u00f3n Unicode y luego eliminar todos los espacios en blanco y luego comprobar si hay una cadena en blanco. Este problema se solucion\u00f3 en la versi\u00f3n 1.18.0."
