CVE-2026-73716Network attack vector

Privileged command execution via OS command injection

Published Sep 1, 2026 · Updated Sep 2, 2026

OS command injection in HPE Aruba Networking Fabric Composer 7.0.0 through 7.3.3 allows remote attackers to execute privileged host commands. HPE identifies the locus only as the underlying operating system and has not disclosed which command path fails to neutralize untrusted input. Exploitation requires user interaction and preconditions outside the attacker's control, but success grants privileged command execution and complete host compromise.
