CVE-2026-78583

HighCVSS 8.1/10Last modified Sep 8, 2026

Description

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.
