      "value": "Ghost is a Node.js content management system. Prior to 6.54.1, any staff-level user was able to leak the hashed passwords of other staff users through the Ghost Admin API. An offline password-guessing attack against the hashes could lead to account takeover if successful, but Device Verification should have prevented an attacker from logging in with a recovered password. Depending on the database used, leaked hashes may not have had the correct casing for all characters, increasing the difficulty of a password-guessing attack. This issue is fixed in version 6.54.1."

      "value": "Ghost es un sistema de gestión de contenido Node.js. Antes de la versión 6.54.1, cualquier usuario con nivel de personal podía filtrar las contraseñas con hash de otros usuarios de personal a través de la API de administración de Ghost. Un ataque de adivinanza de contraseñas sin conexión contra los hashes podría llevar a la toma de control de la cuenta si tenía éxito, pero la Verificación de Dispositivo debería haber impedido que un atacante iniciara sesión con una contraseña recuperada. Dependiendo de la base de datos utilizada, los hashes filtrados podrían no haber tenido el uso de mayúsculas y minúsculas correcto para todos los caracteres, aumentando la dificultad de un ataque de adivinanza de contraseñas. Este problema está solucionado en la versión 6.54.1."
