CVE-2018-10855: Medium severity redhat Ansible Engine vulnerability
Ansible 2.5 prior to 2.5.5, and 2.4 prior to 2.4.5, do not honor the nolog task flag for failed tasks. When the nolog flag has been used to protect sensitive data passed to a task from being logged, and that task does not run successfully, Ansible will expose sensitive data in log files and on the terminal of the user running Ansible.
Other sources
Ansible through version 2.5 does not properly honour the nolog option with failed task iterations. When a list of secret items is supplied to a task and a task iteration fails, secrets can be disclosed in logs despite the nolog option being enabled.
