CVE-2026-82299Network attack vectorHinoki check available

Authenticated information disclosure through Fleet debugging interfaces

Published Sep 3, 2026 · Updated Sep 3, 2026

Kibana 9.0.0 through 9.4.5 and 9.5.0 through 9.5.2 allows remote authenticated users to read sensitive data through incorrect authorization. Elastic identifies Fleet debugging interfaces as the affected locus but has not disclosed the specific endpoint or faulty authorization operation. Exposure requires Fleet debugging interfaces to be enabled, and the reported consequence is information disclosure without data modification or service interruption.
