Background
Ansible is an open-source automation tool that allows users to automate IT tasks such as configuration management, application deployment, and orchestration. It uses a declarative language to describe system configurations and relies on modules to perform specific tasks. The 'uri' module in Ansible is used to send HTTP or HTTPS requests to a specified URI. This module is vulnerable to an Improper Output Neutralization for Logs flaw, which exposes sensitive data to content and JSON output.
