CVE-2026-73739

Administrative disclosure of cleartext sensitive information

Published Sep 1, 2026 · Updated Sep 1, 2026

Information disclosure in HPE Aruba Networking Fabric Composer 7.0.0 through 7.3.3 allows local users to read cleartext sensitive information. HPE identifies the affected locus only as the product API and has not disclosed which endpoint returns protected data or the operation that exposes it in cleartext. Exploitation requires administrative privileges and local access; the reported consequence is confidentiality loss that can expose information useful for further access to supported network services.
