Technical details
The vulnerability is an authorization bypass in the API of HPE Networking Fabric Composer that allows authenticated low-privilege operator users to access data beyond their assigned privilege level. The flaw enables an attacker with valid credentials to retrieve sensitive information that should be restricted to higher-privilege roles. This information disclosure could facilitate further attacks on downstream network services managed by the platform. Authentication is required to exploit this vulnerability, limiting the attack surface to users with valid accounts.
