Executive Summary

CVE-2026-72652 is an Allocation of Resources Without Limits or Throttling vulnerability (CWE-770) in Kibana. It allows an authenticated user to submit a specially crafted request that causes excessive resource consumption, leading to a denial of service. The issue specifically affects deployments using the Timeline feature.

Detection Guidance

Monitor Kibana logs for excessive resource consumption or unusual Timeline feature usage. Check for high CPU/memory usage on Kibana nodes during authenticated sessions. Use Elasticsearch monitoring APIs to track resource allocation trends.

Impact Analysis

This vulnerability can render Kibana unavailable by consuming excessive resources, disrupting normal operations. It requires an authenticated account with access to the Timeline feature to exploit. Systems running affected Kibana versions (8.0.0 to 8.19.18 and 9.0.0 to 9.3.4) are vulnerable.

Compliance Impact

This vulnerability could indirectly impact compliance with GDPR or HIPAA by causing system unavailability, potentially leading to disruptions in data processing or access. Denial of service conditions may violate availability requirements in these regulations, especially if the affected system handles sensitive personal or health data.

Mitigation Strategies

Upgrade Kibana to version 8.19.19 or 9.3.5 or later. If upgrading is not possible, restrict access to the Timeline feature for authenticated users until patched.
