The remote Redhat Enterprise Linux 7 / 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:3600 advisory.
Ansible: masked keys for uri module are exposed into content and json output (CVE-2020-14330)
Ansible: module_args does not censor properly in --check mode (CVE-2020-14332)
ansible: dnf module install packages with no GPG signature (CVE-2020-14365)
ansible: atomic_move primitive sets permissive permissions (CVE-2020-1736)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
