CWE-400

Description

Uncontrolled Resource Consumption (CWE-400) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated attacker with low-privilege access can trigger a denial of service condition in Kibana by sending a specially crafted, oversized request payload. Processing this user-supplied input requires resource-intensive memory allocation that can exhaust the available heap memory in the Kibana process, causing it to crash and become unavailable to all users.

Affected configurations

• elastic kibana (>= 8.0.0 < 8.19.19) • elastic kibana (>= 9.0.0 < 9.3.8) • elastic kibana (>= 9.4.0 < 9.4.4)
