CVE-2026-33460: CWE-863 Incorrect Authorization in Elastic Kibana
CVE-2026-33460 is an incorrect authorization vulnerability in Elastic Kibana affecting versions 8. 0. 0, 9. 0. 0, and 9. 3. 0. It allows a user with Fleet agent management privileges in one Kibana space to access Fleet Server policy details from other spaces. This occurs because an internal enrollment endpoint uses an unscoped internal client that bypasses space-scoped access controls, exposing operational identifiers, policy names, management states, and infrastructure linkage details from unauthorized spaces. The vulnerability has a medium severity with a CVSS score of 4.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-33460) in Elastic Kibana arises from incorrect authorization (CWE-863) where an internal enrollment endpoint bypasses space-scoped access controls by using an unscoped internal client. As a result, a user with Fleet agent management privileges in one space can retrieve sensitive Fleet Server policy information from other spaces they are not authorized to access. The exposed data includes operational identifiers, policy names, management states, and infrastructure linkage details. The issue affects Kibana versions 8.0.0, 9.0.0, and 9.3.0. The CVSS 3.1 base score is 4.3, indicating medium severity. No patch or official remediation level has been published as of the vulnerability disclosure date.
Potential Impact
The impact is limited to unauthorized disclosure of Fleet Server policy details across Kibana spaces. There is no indication of integrity or availability impact. The information disclosed includes operational identifiers, policy names, management states, and infrastructure linkage details, which could aid an attacker in understanding or mapping the environment but does not directly allow modification or disruption of services. No known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Fleet agent management privileges to trusted users only to minimize risk. Monitor Elastic's advisories for updates on patches or mitigations addressing this vulnerability.
