CRITICAL 9.8EPSS 4.84%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (4.84%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Ansible before versions 2.3.1.0 and 2.4.0.0 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.
