Privilege escalation via API authorization bypass
Published Sep 1, 2026 · Updated Sep 3, 2026
Privilege escalation in affected AOS-CX 10.10, 10.13, 10.16, 10.17, and 10.18 releases allows remote authenticated users to change settings. HPE identifies broken access control in an API endpoint but has not disclosed the endpoint, affected setting classes, or failed authorization check. Operator-level credentials are required; the flaw crosses the documented read-only operator boundary and permits unauthorized configuration-state changes.
