CVE-2026-23820Network attack vector

Authenticated OS command execution via inconsistent CLI filtering

Published May 12, 2026 · Updated May 12, 2026

OS command injection in affected HPE Aruba Networking AOS-8 Instant and AOS-10 AP releases allows remote authenticated users to run commands. HPE attributes the flaw to inconsistent CLI input filtering but does not identify the affected command, parser, or unsanitized input path. High-privilege CLI access is required; exploitation escapes the restricted shell and grants arbitrary command execution on the access point.
