CWE-400

Description

Uncontrolled Resource Consumption (CWE-400) in Elasticsearch can lead to denial of service via Excessive Allocation (CAPEC-130). A low-privileged authenticated user can submit a specially crafted query that causes uncontrolled memory growth in the query processing engine, resulting in an out-of-memory condition that terminates the Elasticsearch node. The condition can be triggered repeatedly, including by queries embedded in shared resources, causing persistent cluster unavailability.

Affected configurations

• elastic elasticsearch (>= 8.0.0 < 8.19.23) • elastic elasticsearch (>= 9.0.0 < 9.4.8) • elastic elasticsearch (>= 9.5.0 < 9.5.5)
