Critical (9.8) in redhat ansible. EPSS 3.5% chance of exploitation in the next 30 days. Fixed in ansible 1.6.7.
Ansible before 1.6.7 does not prevent inventory data with "{{" and "lookup" substrings, and does not prevent remote data with "{{" substrings, which allows remote attackers to execute arbitrary code via (1) crafted lookup('pipe') calls or (2) crafted Jinja2 data.
