CVE-2026-78582Network attack vectorHinoki check available

Cross-space monitor deletion via incomplete authorization

Published Sep 26, 2026 · Updated Sep 26, 2026

Missing authorization in Elastic Kibana allows remote authenticated users to delete Synthetics monitors shared with inaccessible spaces. The Synthetics monitor deletion flow accepts a monitor visible in one space and removes the shared saved object and associated private-location integration without checking privileges for every referenced space or applying Fleet authorization. Exposure requires Kibana spaces and a monitor shared across spaces; deletion permanently removes the monitor and can also destroy its Elastic Agent integration configuration.
