OpenStack disclosed OSSA-2026-008 for a command injection vulnerability in Ironic IPMI console implementations, later assigned CVE-2026-42510. The flaw allows a project manager designated as a node.owner to inject arbitrary commands that are executed by an Ironic conductor when a console session is activated. The issue was reported by Dmitry Tantsur and Tuomo Tanskanen of the Metal3.io Security Team.
The vulnerability affects specific Ironic versions only when the optional ipmitool-shellinabox or ipmitool-socat console interfaces are explicitly enabled through enabled_console_interfaces; OpenStack noted that console backends are disabled by default. Patches were released for maintained and some unmaintained branches, and OpenStack warned that ipmitool-shellinabox is already slated for removal because of security support concerns, urging security-sensitive operators to stop using it immediately.
