CVE-2026-72655Network attack vectorHinoki check available

Unauthorized case modification via unchecked API attributes

Published Aug 13, 2026 · Updated Aug 13, 2026

Authorization bypass in Elastic Kibana 8.0.0 through 8.19.19 and 9.0.0 through 9.4.4 allows remote authenticated users to alter case data. The case management API accepts user-controlled object attributes without applying the case-edit authorization enforced by the user interface. View-only case access is sufficient to modify case records, and all configurations in the affected releases expose the behavior.
