CVE-2018-10855: Inclusion of Sensitive Information in Log Files

July 3, 2018 (updated July 25, 2019)

Ansible does not honor the no_log task flag for failed tasks. When the no_log 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.
