Published Sep 23, 2026CWE-862EPSS 0.45%

Overview

CVE-2026-84719 is a critical-severity vulnerability. It was published on September 23, 2026 and has a CVSS 3.1 base score of 9.9 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.9, rated CRITICAL. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
