What it is

A flaw was found in the Ansible Automation Platform automation-controller. When a

WorkflowJobTemplate is copied, the deep-copy permission sanitizer validates only the inventory,

unified_job_template, and credentials of each cloned node and fails to check the instance_groups

(and execution_environment and labels) that were preserved from the original. A user with

organization workflow-admin permission but no role on the referenced instance groups can copy a

workflow, become its administrator, and launch jobs pinned to instance groups they are not

authorized to use — including the control-plane instance group — bypassing the InstanceGroup

use_role boundary and causing attacker-influenced automation to run in the control-plane

execution context.
