Description

The remote Redhat Enterprise Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:71112 advisory.

Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing IT automation at scale.

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.
