Last modified
CVE-2026-78609 is a medium-severity vulnerability rated 5.4/10 on the CVSS scale. Incorrect Authorization (CWE-863) in Elastic Cloud on Kubernetes (ECK) can lead to unauthorized modification of data via Metadata Spoofing (CAPEC-690). An actor holding limited Kubernetes permissions confined to a single namespace could cause attacker-controlled certificate material to be included in the Elasticsearch client trust bundle managed by ECK in a separate namespace.. EPSS estimates a 0.09% chance of exploitation in the next 30 days.
