Summary
Ansible Exposes Sensitive Information
Details

A flaw was found in the Ansible Engine prior to 2.10.6rc1, 2.9.18rc1, and 2.8.19rc1, where sensitive info is not masked by default and is not protected by the no_log feature when using the sub-option feature of the basic.py module. This flaw allows an attacker to obtain sensitive information. The highest threat from this vulnerability is to confidentiality.
