Summary

CVE-2025-68386 is a medium-severity Incorrect Authorization (CWE-863) vulnerability in Elastic Kibana. Its CVSS base score is 4.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-24 (Access Control Decisions) — see the control section below for these in your framework.

Vulnerability Data

Improper Authorization (CWE-285) in Kibana can lead to privilege escalation (CAPEC-233) by allowing an authenticated user to change a document's sharing type to "global," even though they do not have permission to do so, making it visible to everyone in…

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

Improper authorization (CWE-863) directly enables privilege escalation by bypassing access controls on document sharing via crafted requests.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authorization checks on the document sharing-type change action, blocking the unauthorized escalation to global visibility.

prevent

Ensures users are granted only the minimum privileges required, preventing an authenticated user from possessing the ability to alter sharing scope.

prevent

Requires the system to render an explicit access-control decision before permitting the crafted request to modify a document's sharing type.

PR.AA-05 mostly match
prevents

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

prevents

By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
