Authenticated privilege escalation via API authorization failure
Published Sep 1, 2026 · Updated Sep 2, 2026
Improper authorization in HPE Aruba Networking Fabric Composer 7.0.0 through 7.3.3 allows remote authenticated users to alter settings. The API accepts low-privilege operator requests for certain settings without enforcing the authorization required for those state changes. Low-privilege operator credentials are required, and the published impact is unauthorized configuration change without disclosed data access or code execution.
