Auth bypass in Red Hat Ansible Automation Platform 2
CVE-2026-84470
A flaw was found in Ansible Automation Platform's automation-controller (AWX). The Bulk Job Launch API (POST /api/v2/bulk/job_launch/) authorizes the requested instance_groups with only a read-level permission check, whereas the standard single-job launch path requires use-level permission on the same field. A principal that holds read (but not use) permission on an instance group -- for example the built-in read-only System Auditor role -- together with execute permission on a job template can launch bulk jobs onto instance groups they are not authorized to use, bypassing execution-placement isolation.
