Winlogbeat versions before 5.6.16 and 6.6.2 had an insufficient logging flaw. An attacker able to inject certain characters into a log entry could prevent Winlogbeat from recording the event.
When a security-critical event occurs, the product either does not record the event or omits important details about the event when logging it.
