CVE-2026-73736Network attack vector

Unauthenticated system-file disclosure

Published Sep 1, 2026 · Updated Sep 1, 2026

Information disclosure in HPE Aruba Networking Fabric Composer 7.0.0 through 7.3.3 allows remote attackers to read some system files. HPE identifies the web-based management interface as the exposed component but has not published the request path or the operation that permits files in the affected directory to be read. No authentication or user interaction is required, and the reported consequence is limited to file confidentiality without data modification or service interruption.
