CVE-2026-72681: CWE-862 Missing Authorization in Elastic Kibana
Kibana Agent Builder does not correctly verify that the requesting user holds the privileges required by a separate Kibana feature before it creates and runs a tool that invokes that feature's functionality. This allows privilege escalation and could lead to disclosure of sensitive information that the user is not authorized to read.
AI Analysis
Technical Summary
The vulnerability in Elastic Kibana 9.4.0 involves improper authorization checks in the Kibana Agent Builder component. Specifically, it does not correctly verify that the user requesting the creation and execution of a tool holds the required privileges for the invoked feature. This missing authorization (CWE-862) can lead to privilege escalation and unauthorized disclosure of sensitive data. There is no vendor-provided patch or official remediation level indicated in the available data. No known exploits are reported in the wild.
Potential Impact
An attacker with limited privileges can exploit this vulnerability to escalate their privileges within Kibana and access sensitive information that should be restricted. This could lead to unauthorized data disclosure but does not affect system integrity or availability according to the CVSS vector.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to Kibana 9.4.0 to trusted users only and monitor for suspicious activity related to privilege escalation attempts.
