CVE-2026-44856Network attack vector

Authenticated code execution via PAPI stack overflow

Published May 12, 2026 · Updated May 12, 2026

Stack-based buffer overflow in HPE Aruba Networking AOS-8 and AOS-10 allows remote authenticated users to execute elevated code. HPE identifies PAPI management services reached through the CLI but does not disclose the affected parser, request field, or specific unsafe buffer operation. Exploitation requires administrative credentials and crafted CLI requests; success yields arbitrary code with elevated operating-system privileges.
