CVE-2026-76658
CriticalCVSS 10.0Summary
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.
Risk Assessment
An attacker could gain full control of the AFC host, potentially leading to compromise of the entire infrastructure managed by Fabric Composer.
Recommendation
Apply HPE patches immediately and restrict SSH access to trusted networks.
