3Description
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.
Analysis
Kibana's Fleet agent management endpoint fails to enforce space-scoped access controls, allowing authenticated users with Fleet privileges in one space to retrieve sensitive Fleet Server policy details from unauthorized spaces including policy names, operational identifiers, and infrastructure linkage information. The vulnerability affects Kibana across multiple versions and requires valid user authentication with Fleet agent management permissions, resulting in cross-space information disclosure without the ability to modify data.
