Improper Neutralization of Special Elements in Data Query Logic (CWE-943) in Kibana can lead to information disclosure via NoSQL Injection (CAPEC-676). An authenticated user with access to the affected query functionality could submit specially crafted input that alters the intended query logic, returning data the user is not authorized to read.
AnalysisAI
NoSQL injection in Kibana exposes unauthorized Elasticsearch data to authenticated low-privilege users who can submit crafted query input. The flaw, classified as CWE-943 (Improper Neutralization of Special Elements in Data Query Logic / CAPEC-676), allows manipulation of backend NoSQL query logic to return records outside the user's authorized data scope. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid Kibana user account with access to the affected query functionality; the CVSS PR:L metric confirms low-privilege authentication is sufficient and no administrative role is needed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N places this squarely in the medium-to-high band: network-reachable, low complexity, requiring only a valid low-privilege account, with high confidentiality impact. … 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 9.4.5 or 9.5.1 as detailed in Elastic security advisory ESA-2026-168 (https://discuss.elastic.co/t/kibana-9-4-5-9-5-1-security-update-esa-2026-168/390082). … Detailed patch versions, workarounds, and compensating controls in full report. |
