CVE-2024-11079

Ansible-core: unsafe tagging bypass via hostvars object in ansible-core

Description

A flaw was found in Ansible-Core. This vulnerability allows attackers to bypass unsafe content protections using the hostvars object to reference and execute templated content. This issue can lead to arbitrary code execution if remote data or module outputs are improperly templated within playbooks.

Remediation

Workaround:

  • To mitigate this vulnerability, avoid using the hostvars object to reference content marked as !unsafe. Ensure that all remote data from modules or lookups is properly sanitized and validated before use in playbooks. Additionally, restrict access to inventory files and Ansible playbooks to trusted users to minimize exploitation risks.
