CWE-789

Description

Memory Allocation with Excessive Size Value (CWE-789) in Elasticsearch can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated user with connector management privileges could cause the cluster to allocate an uncontrolled amount of memory when connector resources with an excessively large `description` field are created and subsequently accessed, exhausting available heap memory and crashing the affected node.

Affected configurations

• elastic elasticsearch (>= 8.12.0 < 8.19.23) • elastic elasticsearch (>= 9.0.0 <= 9.3.8) • elastic elasticsearch (>= 9.4.0 < 9.4.8) • elastic elasticsearch (>= 9.5.0 < 9.5.5)
