Fixed In Version: ansible 2.3.1.0, ansible 2.4.0.0
Doc Type: If docs needed, set a value
Doc Text:
An input validation flaw was found in Ansible, where it fails to properly mark lookup-plugin results as unsafe. If an attacker could control the results of lookup() calls, they could inject Unicode strings to be parsed by the jinja2 templating system, resulting in code execution. By default, the jinja2 templating language is now marked as 'unsafe' and is not evaluated.

Description Borja Tarraso 2017-05-11 11:59:49 UTC
Jason McKerr of Red Hat reports:

Data returned in lookup() variables is not marked as unsafe and could result in unicode strings being passed through to the jinja2 templating system.
