What is CVE-2026-84719?
CVE-2026-84719 is a critical missing authorization vulnerability in Red Hat Ansible Automation Platform 2.4 for RHEL 8, published on 23 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
