Summary
Ansible discloses sensitive information in traceback error message
Details

Ansible is an IT automation system that handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. A flaw was found in Ansible Engine's ansible-connection module where sensitive information, such as the Ansible user credentials, is disclosed by default in the traceback error message when Ansible receives an unexpected response from set_options. The highest threat from this vulnerability is confidentiality.
