Administrative access via adjacent authentication bypass
Published Sep 1, 2026 · Updated Sep 2, 2026
Authentication bypass in HPE Networking Fabric Composer 7.0.0 through 7.3.3 allows attackers to gain administrative access over an adjacent network. The flaw is in the underlying operating system, but HPE has not disclosed the affected authentication control or the incorrect operation that permits bypass. No credentials or user interaction are required, but high-complexity conditions and adjacent-network access are necessary; successful exploitation permits configuration changes and access to or manipulation of sensitive data.
