CVE-2026-76673Network attack vector

Unauthenticated administrative access

Published Sep 15, 2026 · Updated Sep 21, 2026

Authentication bypass in HPE Networking EdgeConnect SD-WAN Orchestrator allows remote attackers to gain administrative privileges via its API. HPE identifies the API as the affected locus but does not disclose which endpoints or validation operation improperly accepts unauthenticated requests. No account or user interaction is required, and successful exploitation grants administrative control leading to complete compromise of the Orchestrator host.
