CVE-2024-37280: Elastic Elasticsearch

Medium severity, CVSS 4.9. EPSS: 0.6% chance of exploitation in the next 30 days.

A flaw was discovered in Elasticsearch, affecting document ingestion when an index template contains a dynamic field mapping of “passthrough” type. Under certain circumstances, ingesting documents in this index would cause a StackOverflow exception to be thrown and ultimately lead to a Denial of Service. Note that passthrough fields is an experimental feature.

Affected products

• Elastic Elasticsearch: from 8.13.1, before 8.14.0 (fixed in 8.14.0)
