CVE-2026-73745Network attack vector

Unauthenticated internal service information disclosure

Published Sep 1, 2026 · Updated Sep 2, 2026

Information disclosure in HPE Aruba Networking Fabric Composer 7.0.0 through 7.3.3 allows remote attackers to view internal service data. HPE identifies an unspecified API endpoint but has not disclosed the request, response fields, or validation failure that exposes the information. Exploitation requires no privileges but does require user interaction and high-complexity conditions; the disclosed consequence is limited insight into internal services and workflows.
