CVE-2026-33461: CWE-863 Incorrect Authorization in Elastic Kibana
Incorrect Authorization (CWE-863) in Kibana can lead to information disclosure via Privilege Abuse (CAPEC-122). A user with limited Fleet privileges can exploit an internal API endpoint to retrieve sensitive configuration data, including private keys and authentication tokens, that should only be accessible to users with higher-level settings privileges. The endpoint composes its response by fetching full configuration objects and returning them directly, bypassing the authorization checks enforced by the dedicated settings APIs.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-33461) in Elastic Kibana involves incorrect authorization (CWE-863) where an internal API endpoint bypasses intended access controls. Users with limited Fleet privileges can retrieve sensitive configuration data, including private keys and authentication tokens, that should only be accessible to users with higher-level settings privileges. The flaw stems from the endpoint composing its response by fetching full configuration objects and returning them directly without enforcing the authorization checks that dedicated settings APIs apply. Affected versions include 8.0.0, 9.0.0, and 9.3.0. The CVSS 3.1 score is 7.7 (high severity), reflecting network attack vector, low attack complexity, privileges required, no user interaction, scope change, and high confidentiality impact. No official patch or remediation level has been published by Elastic as of the data provided.
Potential Impact
An attacker with limited Fleet privileges can abuse this vulnerability to disclose sensitive configuration data such as private keys and authentication tokens. This unauthorized information disclosure could compromise the security of the affected Kibana deployment by exposing credentials and secrets that are intended to be restricted to higher-privileged users. There is no indication of impact on integrity or availability. No known exploits in the wild have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Fleet user privileges to trusted personnel only and monitor access to internal API endpoints if possible. Avoid granting Fleet privileges to untrusted users. Follow Elastic's official advisories for updates on patches or mitigations.
