CVE-2026-73729

Sensitive-data disclosure through undisclosed OS flaw

Published Sep 1, 2026 · Updated Sep 2, 2026

Information disclosure in HPE Aruba Networking Fabric Composer 7.0.0 through 7.3.3 allows local users to read sensitive data. HPE identifies the underlying operating system and upstream AFC dependencies as the affected area but has not disclosed the specific locus or operation that exposes data. Exploitation requires authenticated low-privilege operator access to those local dependencies and reveals data beyond the account's authorization boundary.
