CVE-2026-76740Network attack vector

Remote command execution on rack management controllers

Published Oct 19, 2026 · Updated Oct 19, 2026

Command execution in HPE Superdome Flex RMC allows remote attackers to execute arbitrary commands through the management network. The supplied advisory also covers HPE Superdome Flex 280 Server and HPE Compute Scale-up Server 3200 and 3250, but does not identify the affected endpoint or input-handling defect. Exploitation targets the Rack Management Controller rather than a named host application; authentication requirements and consequences beyond controller command execution remain unverified in retrievable primary material.
