CVE-2026-102410: Missing Authorization in Kibana Leading to Information Disclosure
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.

Frequently Asked Questions
Which users are exposed to this authorization gap?
A user must have data-store-level read access to an index but lack the corresponding Kibana feature privilege. Such a user may still retrieve index-derived metric data through the affected internal Metrics Experience API surface.
What access does exploitation provide?
The issue enables disclosure of index-derived metric data that a properly authorized related API would block. The provided impact information indicates confidentiality impact only, with no integrity or availability impact.
