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 simple and human-readable language called YAML to define automation tasks. Ansible is widely used in the industry due to its simplicity and scalability. However, a vulnerability has been discovered in Ansible that could lead to the disclosure of sensitive data.
Vulnerability Detail
The vulnerability (CVE-2020-1736) in Ansible Engine occurs when a file is moved using the atomic_move primitive.
