Privilege escalation via API authentication bypass
Published Sep 1, 2026 · Updated Sep 3, 2026
Authentication bypass in the API endpoint of HPE AOS-CX switches allows remote attackers to obtain privileged API access. HPE has not disclosed the affected API routes or the request-processing error that circumvents authentication. Exploitation requires network access to the management API and specific undisclosed conditions, after which the attacker gains the privileges exposed by the affected endpoint.
