Description Tapas Jena 2021-06-07 10:57:58 UTC 
if there are ansible users out there who are trying to put templates in multi-line yaml strings(https://yaml-multiline.info/), and the facts being
handled don't routinely include special template characters, then their controller will be vulnerable to a template injection through the facts used in template.
Comment 2 Tapas Jena 2021-06-08 06:13:27 UTC 
Analysis is complete and its found to be a legitimate issue. The issue has been successfully reproduced. Hence, marking it as "Affected" -> "fix" for AAP 1 and Ansible Tower.
