Live › vulnerability › CVE-2026-116755
The Orchestrator component of SoftIron HyperCloud passes VM template content, such as the description field, into a shell here-document without quoting the terminator, so injected shell syntax is executed. An attacker with valid management-plane credentials can run arbitrary commands as the privileged orchestration user on hypervisor hosts during deploy, migrate, or network setup.
Summary written from the sources below. Check the originals before acting.

Organizations running SoftIron HyperCloud Orchestrator from 1.0 through 2.6.17 are affected. Exploitation requires valid credentials and access to the management plane; owning a virtual machine alone is not enough. Deployments where only tightly restricted operators can reach the management plane have a smaller exposure, but the sources do not say how to scope that further.

2.6.18Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
Improper Neutralization of Special Elements used in a Command ('Command Injection') in the Orchestrator component of SoftIron HyperCloud allows an authenticated user with access to the management plane to execute arbitrary operating system commands on hypervisor hosts as the privileged orchestration user. Attacker-controlled virtual machine template content (for example, the VM DESCRIPTION field) is delivered to hosts through a shell here-document whose terminator is not quoted, so shell expansion and here-document terminator injection are performed on that content during virtual machine lifecycle operations such as deploy, migrate, and network setup. Exploitation requires valid credentials, access to the management plane (owning a virtual machine alone is not sufficient), and a lifecycle operation that reaches the affected host. This issue affects the Orchestrator component of SoftIron HyperCloud from 1.0 through 2.6.17 and is fixed in 2.6.18.
