Summary
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.
Red Hat severity: Moderate — CVSS 6.4 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:L). Weakness: CWE-862.
Affected Red Hat products: Red Hat Ansible Automation Platform 2. Red Hat does not currently list a fixing RHSA for this CVE.

Mitigation checklist
- - Restrict who holds the System Auditor role and avoid combining it with job-template execute grants; review custom roles that pair read on instance groups with execute on job templates. - Where feasible, restrict access to the Bulk Job Launch endpoint (/api/v2/bulk/job_launch/) at the network/proxy layer to trusted automation callers until the fix is applied. - Audit workflow/bulk jobs for placement onto instance groups the launching principal does not hold use_role on.
