CVE-2026-72660 is a vulnerability in Kibana where an uncaught exception caused by improper input validation can lead to a denial of service. An authenticated user with low privileges can supply specially crafted data that triggers an internal error, causing the Kibana process to terminate. This results in service unavailability until the system is restarted. The issue affects multiple Kibana versions prior to specific fixed releases. No known exploits are reported in the wild, and a patch is available.

Uncaught Exception (CWE-248), resulting from Improper Input Validation (CWE-20), in Kibana can lead to denial of service via Input Data Manipulation (CAPEC-153). An authenticated user holding only low-privileged access can cause an internal error condition in Kibana by supplying specially crafted data. The resulting error is raised on an execution path so it propagates as an uncaught exception and terminates the Kibana process. Kibana is unavailable to all users until the service is restarted, and the condition can be triggered repeatedly.
