    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):

    * ansible-rulebook: exposure inventory passwords in plain text when starting a rulebook activation with
    verbosity set to debug in EDA (CVE-2025-2877)
