CVE-2024-11079 (opens in a new tab)How to fix?
Upgrade ansible-core to version 2.18.0 or higher.
Overview
ansible-core is an a radically simple IT automation system. It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. Ansible makes complex changes like zero-downtime rolling updates with load balancers easy.
Affected versions of this package are vulnerable to Improper Input Validation through the use of the hostvars object. Attackers can bypass unsafe content protections and execute templated content, leading to arbitrary code execution. This is only exploitable if attackers can modify the content returned to a play that utilizes hostvars to reference unsafe content
Workaround
Restrict access to inventory files and Ansible playbooks to trusted users to minimize exploitation risks and avoid using the hostvars object to reference content marked as !unsafe.
