Allocation of Resources Without Limits or Throttling (CWE-770) in Kibana can lead to a denial of service via Excessive Allocation (CAPEC-130). An authenticated user with low-level permissions could submit a specially crafted request that causes excessive resource consumption, which may render Kibana unavailable.
AnalysisAI
Denial of service in Elastic Kibana allows any authenticated low-privilege user to render the analytics interface unavailable by submitting specially crafted requests that trigger unbounded resource consumption (CWE-770, CAPEC-130). All Kibana versions prior to 8.19.17 and 9.3.0 are affected. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid Kibana account with at minimum low-level permissions - confirmed by CVSS PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.5 Medium score accurately reflects the constrained impact profile: high availability disruption (A:H) offset by the PR:L authentication requirement. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade Kibana to version 8.19.17 (for 8.x deployments) or 9.3.0 (for 9.x deployments) as directed by Elastic security advisory ESA-2026-31 at https://discuss.elastic.co/t/kibana-8-19-17-9-3-0-security-update-esa-2026-31/390050. … Detailed patch versions, workarounds, and compensating controls in full report. |
