CVE-2026-102410

medium

Missing Authorization (CWE-862) in Kibana can lead to information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1).

Vendor / product: Elastic — kibana

Missing Authorization (CWE-862) in Kibana can lead to information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An internal API surface within the Metrics Experience feature did not enforce a Kibana-level authorization check that an equivalent, related API in the same feature did enforce. As a result, a user who held only data-store-level read access to an index, but no corresponding Kibana feature privilege, could retrieve index-derived metric data through Kibana that the properly-authorized API would otherwise have blocked.
