What is CVE-2026-78582?
CVE-2026-78582 is a medium-severity missing authorization vulnerability in Elastic Kibana, published on 26 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
