CVE-2024-37280: Elasticsearch StackOverflow vulnerability
First published: Thu Jun 13 2024(Updated: )
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.
