CVE-2026-73712Network attack vector

Unauthenticated remote command execution

Published Sep 1, 2026 · Updated Sep 3, 2026

Command injection in HPE Aruba Networking Fabric Composer 7.0.0 through 7.3.3 allows remote attackers to execute operating-system commands. HPE identifies the API as the vulnerable locus but has not disclosed the endpoint, parameter, or operation that fails to neutralize command input. No authentication or user interaction is required, but exploitation depends on unspecified high-complexity preconditions outside attacker control and permits complete host compromise.
