## Summary

- **CVE ID:** CVE-2026-72679
- **Severity:** MEDIUM
- **CVSS Score:** 6.5 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
- **CWE:** CWE-674
- **Published:** Aug 13, 2026
- **Last Modified:** Aug 13, 2026

## Description

Elasticsearch does not apply its configurable input length restriction to a user-supplied pattern accepted by an intervals query. Compiling a deeply nested pattern drives unbounded recursion that exhausts the thread stack and raises a fatal error, terminating the Elasticsearch node process and causing a denial of service for that node. An authenticated user holding only read-only privileges on a single searchable index can trigger the condition with one small search request.

## Affected Products

- Elastic — Elasticsearch (8.19.0)
- Elastic — Elasticsearch (9.0.0)
