CVE-2026-78583 (GCVE-0-2026-78583)

Vulnerability from cvelistv5 – Published: 2026-09-03 18:35 – Updated: 2026-09-03 18:49

Title

Incorrect Authorization in Kibana Leading to Privilege Escalation

Summary

Incorrect Authorization (CWE-863) in Kibana can lead to privilege escalation via Input Data Manipulation (CAPEC-153). Elasticsearch cluster privilege declarations originating from integration packages were not validated before being used to mint credentials for enrolled Elastic Agents. A user holding Fleet management privileges could therefore cause every Elastic Agent on a targeted policy to receive a credential carrying arbitrarily elevated Elasticsearch cluster privileges, up to and including full cluster administration.

Severity
