Missing Authorization in Kibana Leading to Unauthorized Deletion of Data

Published: Sep 26, 2026Updated: Sep 26, 2026 Sources: CVE List NVDCWE-862

6.5MEDIUM

Description

Missing Authorization (CWE-862) in Kibana can lead to unauthorized deletion of data via Exploiting Incorrectly Configured Access Control Security Levels (CAPEC-180). An authenticated user holding Synthetics privileges scoped to a single Kibana space could permanently delete Synthetics monitors that are shared into spaces they have no access to. Where a monitor is associated with a private location, the same operation also destroys the underlying Elastic Agent integration configuration without the authorization checks that Fleet would otherwise apply.
