Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The org.elasticsearch:elasticsearch-grok Maven package, versions 7.17.0 up to but not including 8.15.1, is vulnerable to a large recursion in the innerForbidCircularReferences function of the PatternBank class, which can crash the Elasticsearch node. An attacker needs the read_pipeline cluster privilege to trigger it. Upgrade to version 8.15.1 or later.
