CVE-2020-10684

A flaw was found in Ansible Engine, all versions 2.7.x, 2.8.x and 2.9.x
prior to 2.7.17, 2.8.9 and 2.9.6 respectively, when using ansible_facts as
a subkey of itself and promoting it to a variable when inject is enabled,
overwriting the ansible_facts after the clean. An attacker could take
advantage of this by altering the ansible_facts, such as ansible_hosts,
users and any other key data which would lead into privilege escalation or
code injection.
