Technical details
An authorization bypass in the user configuration API endpoint fails to enforce role-based access controls, allowing authenticated users to enumerate all configured users and roles via a single API request regardless of their privilege level. The vulnerable component is the security configuration API on Windows and Linux deployments before version 3.2.0. An authenticated remote attacker with limited privileges can retrieve sensitive enumeration data without proper authorization checks.
