Vulnerability details

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists due to improper honor of 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.
