      "value": "blueprintUE is a tool to help Unreal Engine developers. Prior to 4.2.0, when a password reset is initiated, a 128-character CSPRNG token is generated and stored alongside a password_reset_at timestamp. However, the token redemption function findUserIDFromEmailAndToken() queries only for a matching email + password_reset token pair — it does not check whether the password_reset_at timestamp has elapsed any maximum window. A generated reset token is valid indefinitely until it is explicitly consumed or overwritten by a subsequent reset request. This vulnerability is fixed in 4.2.0."

      "value": "blueprintUE es una herramienta para ayudar a los desarrolladores de Unreal Engine. Antes de la versión 4.2.0, cuando se inicia un restablecimiento de contraseña, se genera un token CSPRNG de 128 caracteres y se almacena junto con una marca de tiempo password_reset_at. Sin embargo, la función de canje de token findUserIDFromEmailAndToken() consulta solo por un par coincidente de correo electrónico + token de restablecimiento de contraseña - no verifica si la marca de tiempo password_reset_at ha excedido alguna ventana máxima. Un token de restablecimiento generado es válido indefinidamente hasta que se consume explícitamente o se sobrescribe por una solicitud de restablecimiento posterior. Esta vulnerabilidad se corrige en la versión 4.2.0."
