CVE-2026-73727Network attack vector

Sensitive information disclosure via improper API authorization

Published Sep 1, 2026 · Updated Sep 2, 2026

Improper access control in HPE Aruba Networking Fabric Composer 7.0.0 through 7.3.3 allows remote authenticated users to read sensitive data. The API permits a low-privilege operator to retrieve information beyond the account's authorized scope, but HPE has not identified the endpoint or failed authorization check. Operator credentials and network access to the management API are required; exposure is limited to confidentiality, although disclosed data can aid access to supported network services.
