Description
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.
