======================================================================= OSSA-2026-008: Command Injection in Ironic IPMI Console Implementations =======================================================================
:Date: April 27, 2026 :CVE: CVE-2026-pending Affects ~~~~~~~ - Ironic: >=4.3.0 <26.1.6, >=27.0.0 <29.0.5, >=30.0.0 <32.0.1, >=33.0.0 <35.0.1 Description ~~~~~~~~~~~ Dmitry Tantsur and Tuomo Tanskanen from the Metal3.io Security Team reported a vulnerability in Ironic's IPMI console backends. A project manager for the project marked as a ``node.owner`` can inject arbitrary commands which a conductor executes on console activation. No console backends are enabled by default in Ironic. Only installations which have set ``[conductor]/enabled_console_interfaces`` to enable either ``ipmitool-shellinabox`` or ``ipmitool-socat`` are vulnerable.

Security sensitive operators are strongly encouraged to stop use of this console interface immediately. Thanks, Jay Faulkner OpenStack Vulnerability Management Team Ironic Security Liason
