CVE-2026-76658Network attack vector

Unauthenticated privileged command execution

Published Sep 1, 2026 · Updated Sep 1, 2026

Improper authentication in HPE Aruba Networking Fabric Composer 7.0.0 through 7.3.3 allows remote attackers to execute privileged commands. HPE identifies the SSH daemon as the affected locus but has not published the authentication error or crafted input that triggers it. No credentials or user interaction are required, and successful exploitation grants administrative access and complete control of the host.
