CVE-2026-33460
MEDIUM4.3EPSS 0.03%Incorrect Authorization in Kibana Fleet Leading to Information Disclosure
Published: 4/13/2026Modified: 4/13/2026
Description
Incorrect Authorization (CWE-863) in Kibana can lead to cross-space information disclosure via Privilege Abuse (CAPEC-122). A user with Fleet agent management privileges in one Kibana space can retrieve Fleet Server policy details from other spaces through an internal enrollment endpoint. The endpoint bypasses space-scoped access controls by using an unscoped internal client, returning operational identifiers, policy names, management state, and infrastructure linkage details from spaces the user is not authorized to access.
