    Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing
    IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to
    individual teams, while automation developers retain the freedom to write tasks that leverage existing
    knowledge without the overhead. Ansible Automation Platform makes it possible for users across an
    organization to share, vet, and manage automation content by means of a simple, powerful, and agentless
    language.

    Security Fix(es):

    * automation-controller: Privilege escalation via provisioning-callback host-match bypass (CVE-2026-84474)
    * automation-controller: Instance-group privilege escalation via workflow job template copy
    (CVE-2026-84719)
    * automation-controller: Arbitrary file read via Project scm_branch git argument injection
    (CVE-2026-84711)
    * automation-controller: Privilege escalation via constructed inventory attachment (CVE-2026-84684)
    * automation-controller: Instance-group privilege escalation via Schedule and workflow node attachment
    (CVE-2026-84638)
    * automation-controller: Remote code execution via Project scm_url git argument injection (CVE-2026-84502)
    * automation-controller: awx: Privilege escalation to OpenShift namespace via pod_spec_override injection
    in container groups (CVE-2026-75884)
    * automation-controller: Kubernetes service account token exfiltration via HashiCorp Vault credential SSRF
    (CVE-2026-12564)
