A vulnerability has been identified in the SSH daemon of HPE Networking Fabric Composer that could allow an unauthenticated remote attacker to gain administrative access to vulnerable AFC hosts. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system leading to complete system compromise.

A critical vulnerability has been identified in the SSH daemon of HPE Networking Fabric Composer (AFC). An unauthenticated remote attacker can exploit this flaw to gain administrative access to vulnerable AFC hosts. Successful exploitation allows arbitrary command execution as a privileged user on the underlying operating system. This leads to complete system compromise without requiring any credentials. The vulnerability is tracked as CVE-2026-76658 and is currently awaiting full analysis by NVD. HPE has published a security bulletin with remediation guidance. The severity is rated High given the unauthenticated remote exploitation vector and full system compromise potential.
