Kibana is vulnerable to a denial of service due to an inefficient algorithmic complexity when processing deeply nested expressions in TSVB visualizations. This vulnerability allows an attacker to manipulate input data, causing the evaluation to consume excessive resources and block all further requests until the service is restarted. Organizations using Kibana should prioritize addressing this issue to maintain service availability and prevent potential disruptions.

Original NVD Description

Inefficient Algorithmic Complexity (CWE-407) in Kibana can lead to denial of service via Input Data Manipulation (CAPEC-153). A specially crafted, deeply nested expression submitted to a Kibana TSVB visualization is evaluated with a worst-case cost that grows disproportionately with the size of the input. Because the evaluation runs synchronously, a single request consumes the Kibana request-processing thread indefinitely, and Kibana stops responding to all further requests until the service is restarted.
