CVE-2026-76691Network attack vector

Authenticated command execution via API buffer overflow

Published Sep 15, 2026 · Updated Sep 22, 2026

Buffer overflows in the HPE EdgeConnect SD-WAN Gateway API allow remote authenticated users to execute privileged operating-system commands. HPE has not identified the affected API operation, input field, or unsafe copy routine, so the precise overflow mechanism is undisclosed. A network-reachable account with high privileges is required; successful exploitation runs commands as a privileged operating-system user.
