| Doc Text: |
A flaw was found in the Timelion visualization plugin in Kibana. An authenticated user can exploit this by sending a specially crafted Timelion expression. This expression overwrites internal series data properties with an excessively large quantity value. This improper validation of input quantity can lead to a Denial of Service (DoS) by causing excessive memory allocation, making the service unavailable.
