## Overview

A flaw was discovered in Elasticsearch, where a large recursion using the innerForbidCircularReferences function of the PatternBank class could cause the Elasticsearch node to crash.

A successful attack requires a malicious user to have read_pipeline Elasticsearch cluster privilege assigned to them.

## Affected packages

- `org.elasticsearch:elasticsearch-grok >= 7.17.0, < 8.15.1`

## Remediation

Upgrade to a patched release:

- `org.elasticsearch:elasticsearch-grok 8.15.1`
