Descriptions
Mattermost fails to enforce character limits in all possible notification props allowing an attacker to send a really long value for a notification_prop resulting in the server consuming an abnormal quantity of computing resources and possibly becoming temporarily unavailable for its users.
Mattermost no aplica límites de caracteres en todos los posibles accesorios de notificación, lo que permite a un atacante enviar un valor muy largo para un notification_prop, lo que hace que el servidor consuma una cantidad anormal de recursos informáticos y posiblemente deje de estar disponible temporalmente para sus usuarios.
